Irreplaceable

y oldest brother, Tom, became a computer guy in the early 1970s. As with many of his ilk, he promised me how much better off we would all be as computers increased in their capabilities and reach. Through the years, we would talk and his enthusiasm for computing never waned, but intensified, if anything.

Of course, my mother was always complaining that the “paperless world” he promised was not showing any sign of appearing anytime soon. And in a shocking development, he was mostly right. I still shake my head when I think of what a pain it was to type out documents, using copious amounts of correction fluid, nearly getting high on the fumes. Then, in the 1980s, we college students were given access to mainframes that let us edit our manuscripts “electronically” before printing them. Of course, there was only one printer, and it was always in a building halfway across campus. However, arriving there and seeing your neat little pile of pages was a thrill (as you can see, my college years were nothing like Animal House.) Before I knew it, not only did I have my own “personal” computer, I could connect to something called the “Internet” and use “electronic mail” to communicate all around the world. Crazy.

Next came cellular phones, further advances in the electronics in everything, and the creation of “screenagers.” (Yes, I am looking at you, children of mine.)

Then came the pièce de résistance: videoconferencing. Although first introduced at the World’s Fair in New York in 1964, it had what might be considered a long incubation period as the quality and extent of the technology were developed. Spouses everywhere rejoiced; no longer would their scientist spouse have to go to the far reaches of the globe to have a geekout with other similar creatures for days on end, never bringing back appropriate gifts for the kids. They could stay home, conference during the day, and still take the trash out and walk the dog at night. Perfect.

It just hasn’t worked out that way. Although it has been great for from two to several people to share information and discussions, I have not seen a conference successfully use it as a full replacement, though heavens knows I have seen it tried. At some level it seems counterintuitive; we in the sciences are comfortable using computers and the technology is good, I must admit. We could gain as much information from talks broadcast over the Internet. (How do you think I figured out how to change my wiper blades?) What we miss is all the other stuff that goes on at conferences—sidebars where we catch up with colleagues on current work or their family, the chance to follow up with a speaker, or meet new colleagues or vendors. That said, we do a lot of that electronically perfectly well, thank you. Most people are good about answering emails, and web pages allow some of us to convince people that we have not aged in the 20 years since the photo was taken. So why do we still go to conferences? Hint: it is not the rubber chicken served at Divisional Business Meetings. Face-to-face contact is simply irreplaceable for picking up on body language, for instantly correcting statements that if said in an email or text could be misinterpreted, engendering silence at the very least, and most likely sharp words. We also tend to be civil, I think, during technical discussions when we are in close proximity without the Internet between us. (For a counter example, see any discussion board on any subject anywhere.) The rapport built into these face-to-face meetings can serve as the foundation for future collaborations and much stronger connections. The breakfasts, lunches, receptions, and dinners give us a chance to get to know the person better, though sometimes that familiarity occurs just a little bit at a time over many meetings.

I think this topic struck me after I had traveled eight of the last 13 weeks. Relieved that Heather had not changed the locks, I wondered if it was worth it. In thinking about my conference experiences, I realized that although my brother got all the brains in the family, on this topic he was way off base. Face-to-face scientific conferences are irreplaceable, although they could work on the rubber chicken. Until next time, be safe and happy.

And the

2019 Nobel Prize in Chemistry Goes to…

I

by Marca M. Doeff

t was the week after the announcement of the winners of the 2019 Nobel Prize in Chemistry, and we were gathered together in Atlanta for the 236th meeting of The Electrochemical Society. Given that the prize was awarded to three scientists who performed seminal work leading to the development of the lithium-ion battery—John Goodenough, Stan Whittingham, and Akira Yoshino, the Atlanta Hilton was buzzing with excitement. After all, ECS meetings have been and still are the best settings for hearing about and discussing all things “battery.” One of the winners of the award, Stan Whittingham, was attending the meeting, and was stopped in his tracks constantly by people wanting to shake his hand and offer congratulations or to take selfies with him. That got me to thinking (after taking my own selfie with Prof. Whittingham) about the long journey from these initial discoveries, made in the 1970s and 80s, to where we are today.

The Lithium-Ion Battery Market Today

Lithium-ion batteries enabled the revolution in consumer electronics starting in the late 20th century; there is no doubt that cell phones, tablets, and laptop computers are great conveniences that have made a positive impact on how we conduct our lives and do business in the 21st century. Lithium-ion batteries now are widely used in power tools, cameras, toys, and medical devices as well. The lithium-ion battery market was estimated to be about 37.4 billion USD in 2018, and is projected to grow to 92.2 billion USD in 2024, as demand for electric vehicles (EVs) and hybrid electric vehicles (HEVs) increase.1 The stellar performance and decreasing cost of lithium-ion batteries have transformed EVs from a niche market only for enthusiasts to products attractive to the average driver. Automobiles like the Tesla Model 3, the Nissan Leaf, and the Chevrolet Bolt are readily available to the public for purchase at affordable prices, and nearly every large automaker has EVs or HEVs for sale or under development. Lithium-ion batteries also are being used for behind-the-meter storage (e.g., Tesla’s PowerWall). Another application where lithium-ion batteries will make an impact is grid storage, although they not only have to compete with other types of batteries such as redox flow systems, but other types of energy storage such as pumped hydro. Still, the ever-dropping price of lithium-ion batteries and their excellent reliability make them a natural choice for society’s energy storage needs.

Initial Discoveries that Led to Lithium-Ion Batteries Whittingham’s insight that intercalation chemistry (specifically, lithium insertion into TiS2) could be exploited for use in batteries with lithium metal anodes set the stage. Goodenough discovered LiCoO2, another classical intercalation compound, which undergoes reversible insertion/de-insertion of lithium ions at higher potentials vs. Li+/ Li than TiS2, improving energy density. However, as Goodenough described it, “battery manufacturers at that time could not conceive of assembling a cell with a discharged cathode.”2 The lithium metal anode was, however, unreliable, to say the least. Upon repeated cycling, highly reactive mossy deposits or dendrites of the metal formed, leading to sudden shorts or, worse yet, explosions. When Yoshino revealed that carbons with certain physical characteristics could function as anodes without the drawbacks of lithium metal, the modern version of the lithium-ion battery was born. The system could be cycled much more reliably than lithium metal batteries, and using a pre-lithiated cathode like LiCoO2 was actually an advantage, because cells could be easily assembled in the discharged state and then charged before use.

In 1991, Sony commercialized the first lithium-ion batteries.3 These cells, made with petroleum coke as the anode and LiCoO2 as the cathode, had practical energy densities of about 200 Wh/L and specific energies of about 80 Wh/Kg, less than half that of state-ofthe-art lithium-ion batteries today. Researchers from many different scientific disciplines and countries, in industry, national labs, and academia, worked to advance lithium-ion battery technology, ultimately resulting in a more than doubling of practical energy density as well as a dramatic drop in cost (from more than $1,000/ kWh a decade ago to about $175/kWh today).4 While LiCoO2 is still the cathode of choice for small batteries, low or no-cobalt alternatives such as LiFePO4, variants of LiMn2O4 spinels, and layered transition metal oxides containing multiple metals such as NMCs (LiNixMnyCozO2) and NCA (LiNi0.8Co0.15Al0.05O2) are preferred in devices intended for automotive applications or largescale energy storage because of cost and sustainability concerns. The original petroleum coke anodes have been replaced with graphite or graphite/silicon composites, which offer higher capacities and better first cycle efficiencies. Optimization of electrolytic solutions resulted in improved performance, as did work on binders and separators, and advances in design of electrodes, cells, and battery packs.

While improvement and better understanding of these devices and the materials within them are still high priorities today, research has expanded to include “beyond lithium-ion batteries,” many of which are based on the intercalation concept, but with ions like Mg2+ or Na+. Most of these next-generation systems are still in their infancy, but the remarkable success story of lithium-ion batteries provides a roadmap for their development as well. In short, the pioneering work of Goodenough, Whittingham, and Yoshino so many years ago, will continue to have positive repercussions for years to come. © The Electrochemical Society.

I like to think that part of my heritage is that I contributed to the wedding of physics and chemistry. I didn’t do it alone, of course.

We are moving inevitably, inexorably, to interdisciplinarity between material physic and material chemistry.

ohn Bannister Goodenough is internationally recognized as one of the key minds behind the development of the first commercial lithium-ion battery. The ECS Fellow and honorary member was born on July 25, 1922, in Jena, Germany, to American parents who soon thereafter returned to the United States.1 He completed his BS in math and graduated summa cum laude from Yale University in 1943.2 After serving in World War II as a meteorologist, he completed his PhD in physics at the University of Chicago (1952).3 As a research scientist at the Lincoln Laboratory at the Massachusetts Institute of Technology (1952-1976), he developed the SAGE air defense computer’s memory cores—the first random access memory (RAM).4 In 1976, Goodenough moved

to the University of Oxford as professor and head of the Inorganic Chemistry Lab.5 In 1979-1980, Goodenough improved on the first lithium-ion battery invented by M. Stanley Whittingham in 1976.6 Whittingham’s battery used an anode of metallic lithium, and a cathode of lithium ions between layers of titanium disulfide. It had a potential of 2.5 volts. To produce a higher voltage battery, Goodenough and collaborators used a cathode of lithium ions between layers of cobalt oxide. The new battery had a potential of 4 volts.

Goodenough became a professor at the University of Texas at Austin in 1986 in the departments of mechanical engineering and electrical and computer engineering.7 He now holds the Virginia H. Cockrell Centennial Chair of Engineering at the University of Texas at Austin. Goodenough continues to work on lithium-ion breakthrough technology, determined to make the batteries stronger, cheaper, and safer, and the world less dependent on fossil fuels.8 P © The Electrochemical Society.

ichael Stanley Whittingham was born in Nottingham, England on December 22, 1941.1 He received his BA (1964), MA (1967), and PhD (1968) in chemistry from the University of Oxford.2 He was at Stanford University as a research associate (1968-1972) before joining the Exxon Research and Development Company in Linden, New Jersey.3 At Exxon, Whittingham studied titanium disulfide and its superconductive properties. Using intercalation, he created the first rechargeable lithium-ion battery in 1976.4 He used metallic lithium as the anode and titanium disulfide intercalated with lithium ions as the cathode. The battery had an electromotive force of 2.5 volts.

Together with John Goodenough, Whittingham published Solid State Chemistry of Energy Conversion and Storage in 1977.

Whittingham founded the journal Solid State Ionics in 1981. He served as its editor for 20 years.5 Whittingham joined Schlumberger-Doll Research in Ridgefield, Connecticut, as director of physical sciences in 1984.6 He was then named distinguished professor of chemistry and materials sciences and engineering at Binghamton University, New York, in 1988.7 He is also director of the Northeastern Center for Chemical Energy Storage (NECCES), a Department of Energy (DOE) Energy Frontier Research Center (EFRC) at Binghamton. There Whittingham continues his research on finding new materials for advancing energy storage. P © The Electrochemical Society. DOI: 10.1149/2.2.F03194IF.

kira Yoshino was born on January 30, 1948, in Suita, Japan.1 He was nine years old when he discovered Faraday’s “The Chemical History of a Candle.”2 The book describes the energy stored in a candle and the chemistry behind it. Reading that book sparked Yoshino’s interest in science and shaped his entire life. He received his BA (1970) and MA (1972) in petro chemistry from Kyoto University.3 In graduate school, he focused on chemistry, submitting research papers to the international journals of chemistry societies. After receiving his MA, Akira joined the Asahi Chemical Industry Company (now Asahi Kasei Corporation) in 1972.4

By combining Goodenough’s cathode with a carbon anode, Yoshino created the first working lithium-ion battery. Yoshino filed a patent on his safer, commercially viable lithium-ion battery in 1985.5 The new lithium-ion battery was commercialized by Sony in 1991, and in 1992 by A&T Battery, a joint venture company of Asahi Kasei and Toshiba.6 In 2005, Yoshino received a doctorate in engineering from Osaka University.7 He became president of the Lithium-ion Battery Technology and Evaluation Center in 2010.8 In 2015, he became a visiting professor at the Research and Education Center for Advanced Energy Materials, Devices, and Systems, Kyushu University, a post he holds today9. Since 2017, he has also served as a professor in the Graduate School of Science and Technology, Meijo University.10 Today, Yoshino is an honorary fellow at the Asahi Kasei Corporation.

He continues his research, looking at ways that the lithium-ion battery can address global environmental problems.

Physics

The Nobel Prize The Nobel Prize is named for Swedish inventor, entrepreneur, scientist, and businessman Alfred Nobel (1833-1896). In addition to inventing dynamite, Nobel held 355 different patents. Nobel stipulated in his will that his sizable estate fund prizes for those who “shall have conferred the greatest benefit to mankind” in the areas of physics, chemistry, physiology or medicine, literature, and peace. Since they were first awarded in 1901, the Nobel Prizes have been considered the most important prize in the world for intellectual achievement. In 1969, Sweden’s central bank funded a sixth prize in economics, the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel.

The winners of the 2019 Nobel Prize for Chemistry join a pantheon of celebrated scientists. Marie Curie was the sole winner of the 1911 Nobel Prize in Chemistry. Linus Pauling was the only person to win two unshared Nobel Prizes, the first in 1954 and the second in 1962. Other celebrated chemistry Nobel laureates include Ernest Rutherford, Aziz Sancar, Fritz Haber, Otto Hahn, and Glenn T. Eabord. The only women to win the Nobel Prize in Chemistry are Marie Curie, Irène Joliot-Curie, Dorothy Crowfoot Hodgkin, Ada E. Yonath, and Frances H. Arnold.

Probably the most famous winner of the Nobel Prize in Physics is Albert Einstein.

The first physics prize was awarded to Wilhelm Conrad Röntgen in 1901. Other Nobel laureates of renown in physics include Richard Feynman, William B. Schockley, Werner Heisenberg, Niels Bohr, Max Planck, Guglielmo Marconi, and Enrico Fermi. Three women have won the physics prize: Marie Curie, Maria Goeppert Mayer, and Donna Strickland.

Q&A:

The United States Senate Hearing on Grid-Scale Energy Storage with George W. Crabtree and Lynn Trahey

O

n June 4, 2019, George W. Crabtree, Director of the Joint Center for Energy Storage Research (JCESR) at Argonne National Laboratory, and distinguished professor of physics, electrical, and mechanical engineering at University of Illinois-Chicago (UIC), testified before the U.S. Senate Energy and Natural Resources Committee for a hearing on the expanded deployment of grid-scale energy storage. Senate members in attendance included Ranking Member Joe Manchin (D-WV), Chairman Lisa Murkowski (R-AK), and Bernie Sanders (I-VT). Also present at the hearing were representatives from Brookfield Renewable, Fluence, PJM Interconnection, LLC, and Xcel Energy, Inc. George Crabtree, along with his associate Lynn Trahey, shared with ECS insights for the foundation of the hearing and the importance of electrochemistry to sustainablity.

What is the importance of electrochemistry to sustainability?

Storing energy so that it can be used on demand is a key component of sustainability. There are many ways to store energy.

Filling a gas tank in a car, pumping water uphill, charging a battery or supercapacitor, spinning a flywheel at high speed, compressing air, and heating water or molten salt are all energy storage methods that are in use or under consideration. Each method has advantages and disadvantages. Electrochemical energy storage in batteries is attractive because it is deployable everywhere, controllable, highly flexible, and generally non-polluting. Batteries and electrochemistry allow the most fundamental principles of sustainability—recycle and reuse—to be applied to energy.

Electrochemistry makes energy storage far more sustainable than traditional storage technologies. Energy can be stored chemically in fossil and other fuels for long times at low cost with virtually no self-discharge, making it by far the most popular form of storage today. A significant downside of chemical energy storage is its low efficiency, typically on the order of 35% for combustion to retrieve the stored energy as heat and convert it to a more useable form, such as mechanical motion or electricity. The second downside is less obvious and more insidious: combustion of fossil fuels produces carbon emissions that trap heat in the atmosphere and generate climate change, adversely affecting almost every aspect of society.

Electrochemical energy storage, in contrast, has high round trip efficiency, typically greater than 80%, and is nearly climate neutral, making it the natural choice for a sustainable energy future.

What was your take-away message to the Senate Committee?

Electrochemical energy storage is a new player in the electricity grid that eliminates one of its most restrictive constraints—that we must generate electricity at the same rate that we use it. This constraint is expensive and disruptive. It requires that we build the grid to satisfy peak demand, at least 40% greater than average demand, significantly increasing capital and operating cost. Without storage, an outage of generation or transmission due to extreme weather, forest fires, or a malicious hack disables the entire downstream grid, blacking out power for hours, days or, in the worst cases, weeks.

Batteries provide a locally stored inventory of electricity that can be tapped at will, eliminating dependence on centralized generation and transmission. Electrochemical energy storage on the grid provides greater reliability, resilience, and flexibility at lower capital and operating cost.

Electrochemical energy storage on the grid is still in its infancy.

The few large-scale energy storage installations in place demonstrate its value and its viability. To realize the benefit of storage on the grid, we need to accelerate research and development to achieve lower costs and higher performance, and we need to deploy electrochemical energy storage at scale on the grid to master the best practices for utilizing it effectively.

Why is it important for the research community and scientists to provide input into policy discussions involving science, or which science can inform, to give policymakers the information needed to act?

Energy storage is a fast-developing technology with a host of applications in society, from personal electronics to electric vehicles, long-haul trucks and flight, to electricity delivery on the 18

grid. However, energy storage technology cannot be interfaced with society without innovative policy, regulation, and business plans to guide its deployment. The energy ecosystem must produce many outcomes, including reliability, resilience, low cost, security, and decarbonization. Many players deliver and benefit from these outcomes, spanning grid operators, the business community, the military, and the citizen population. The energy ecosystem cannot advance without a deliberate balance among all the outcomes and players. This is the role of innovative policy and regulation, to encourage the development of new technology and to ensure that it is deployed in the most beneficial way possible. With energy technology developing so rapidly across the board, innovative policy and regulation must advance at an unusually fast pace to keep up. The input of scientists and the research community is essential to create the most advanced, beneficial, and cost-effective energy system of the future.

For ECS members (and other scientists), what would the technical take-away be?

The main technical take-away from the message for policymakers is that a diversity of batteries is needed to meet the diversity of existing and emerging applications. Lithium-ion batteries have been revolutionary, as evidenced by their ubiquity in our lives and their recognition by this year’s Nobel Prize in Chemistry. However, they have limits; lithium ion batteries lack the energy density to efficiently power electric flight or move heavy trucks. They cannot discharge long enough to back up renewable electricity generation on consecutive overcast or calm days. We need different batteries that offer more specialized features, such as extremely high energy density for electric flight and long-haul trucking, long duration, ultrainexpensive batteries for the grid, and in general, batteries with high recyclability. Lower cost is needed for all applications, as batteries are still not cost competitive with many fossil alternatives.

Another take-away is that basic, fundamental research has immediate impact on energy storage and the energy ecosystem. We want researchers to know that with so many urgent applications, very basic scientific discoveries and the development of new materials can lead to patents and start-up companies that improve the technologies we use today or spur a new technology that we will use very soon. An example is membrane materials, sometimes referred to as separators.

These are critical components to most electrochemical devices, and the research needed to improve these materials boils down to organic chemistry, electrochemistry, physical chemistry, and materials chemistry.

What would the Better Energy Storage Technology Act fund?

The Better Energy Storage Technology (BEST) Act is a pioneer in many respects. Congress has recognized the value of energy storage, with the establishment of the bipartisan Advanced Energy Storage Caucus and the introduction of over a dozen energy storage bills in the current Congress. BEST collects provisions from several of these bills into a single legislative package covering reduced cost, long duration discharge, grid-scale storage demonstrations, and standards for regulation of storage deployment and cost recovery.

BEST has been hailed as a milestone for energy storage technology development, policy and regulation, a refreshing holistic approach uniting all three areas. The bill promotes cooperation between The Electrochemical Society Interface • Winter 2019 • www.electrochem.org

DOE and DoD, which share many of the same performance needs in different application spaces. One notable feature is the creation of a DOE prize for recycling used battery materials, an obvious gap in battery technology that must be addressed quickly as battery production accelerates to meet electric vehicle demand. The BEST bill is a welcome beginning to a longer journey toward full strategic energy storage deployment in the electricity grid.

What systems are used for grid-level storage now?

In the United States, grid-level energy storage is mostly achieved with pumped hydroelectric storage. The remainder of the energy storage is achieved by batteries and thermal storage, with a small fraction stored by compressed air and flywheels. This information comes from the DOE Global Energy Storage Database, produced by the Office of Electricity. When you look at the grid-level energy storage that is contracted, announced, or currently under construction, the majority of that storage will be achieved by lithium ion batteries.

There are a few more pumped hydro projects in the pipeline, but the vast majority of projects are electrochemical because of their maturity, versatility, and competitive costs.

The Joint Center for Energy Storage Research (JCESR) led at Argonne has made important advances over its six-year life.

What are some of the highlights?

JCESR develops a new dimension to battery R&D—understanding and building the electrochemistry of battery materials and systems “from the bottom up,” atom by atom and molecule by molecule.

The space of potential battery materials is so vast that it cannot be explored by traditional Edisonian trial and error. An army of graduate students working a lifetime in the laboratory will not make a dent in analyzing the universe of possible battery electrodes, electrolytes, and interfaces. Instead, JCESR began a massive program of computer simulation of promising materials for electrodes and electrolytes, making the database available to the community on an open source basis. This revealed, for example, that multivalent ions can have high mobility in crystalline hosts, new decomposition pathways for electrolytes during plating of multivalent cations, and the systematic trends of operating voltage, capacity, and mobility of intercalation cathodes for multivalent ions. These datasets, valuable in their own right, are now finding additional use on the frontier of computation as training sets for artificial intelligence and machine learning approaches to accelerate the pace of battery materials discovery.

JCESR introduced a new class of materials for flow batteries, redox active oligomers and polymers, or “redoxmers.” Redoxmers offer an enormous design space for active materials in flow batteries, much greater than transition metal ions that are the mainstay of today’s conventional flow batteries. With redoxmers, operating voltage, number of electrons transferred per reaction, solubility, stability, and an entirely new feature, self-healing, can all be designed in at the atomic and molecular level. One notable outcome: using basic machine learning approaches, JCESR has discovered redoxmers that enable flow batteries operating at record voltages.

JCESR created the aqueous air-breathing sulfur battery, a new kind of flow battery designed for long-duration discharge and based on the least expensive active materials. The battery uses sulfur, a cheap and abundant byproduct of refining petroleum, water as the electrolyte, and oxygen in the cathode. This battery is designed to discharge for hours to days at a time, enabled by its low materials cost and liquid electrodes that can be stored in tanks and scaled to arbitrarily large volumes. JCESR spun off a startup company, Form Energy, to pursue commercialization of the battery.

JCESR focuses on transformative materials, chemistries, and architectures for next generation batteries rather than on the batteries themselves. We learned early on that compelling applications drive successful battery research and development, and the rapid pace of emerging applications means today’s batteries may soon be surpassed by tomorrow’s needs. We focus instead on transformative materials, chemistries, and architectures that can be mixed and matched to produce batteries for any future need in the electricity grid or transportation. This approach has much greater and longer-term impact than focusing on specific battery systems.

the U.S. Department of Energy, Office of Science, Basic Energy Sciences.

To wrap up, George, how did you go from the physics of vortices in high-T superconductors and magnetic flux imaging systems to batteries?

I first became interested in energy in 2002 when Basic Energy Sciences asked me to help organize a workshop on the basic science needed to develop the energy technologies of the future. This was well before the strong national interest in energy and climate change that is now prominent in our thinking. I found the experience to be very satisfying, exposing a richness and challenge equal to any in basic science. I was privileged to participate in many following workshops, on hydrogen, superconductivity, extreme materials, and compact light sources, among others, and this solidified my background and thinking on energy. When the opportunity to lead the JCESR proposal emerged, I was ready to take it, eager to explore this emerging area and contribute to the energy transformations that storage will enable. Storage touches nearly every part of the energy system, and fits naturally into the drive for more reliable, resilient, lower cost, and decarbonized energy. I like the strong role basic science plays in energy innovation, and especially the opportunity for connected innovations across applications, battery technology, and raw materials supply chains. Energy storage is one of the most exciting frontiers of science and technology today.

Lynn, how did you go from fab and application of thermoelectrics to battery research?

When researching and developing nanoscale thermoelectric materials, a project funded by the NASA Graduate Student Researchers Program, I became steeped in materials chemistry, electrochemistry, and device application. As my PhD was winding down, I paid attention to what society needed most urgently and matched that with what my skillset afforded me to do. The answer was in renewable energy. I felt I could contribute to the electrochemical storage of energy coming off of solar and wind installations, so I looked for a postdoc where I could learn about batteries. I took a joint postdoc between Northwestern University and Argonne National Lab and have been with Argonne, working on batteries, ever since. © The Electrochemical Society. DOI: 10.1149/2.F15194IF

Her main research interests concern materials for rechargeable lithium-ion, sodium-ion, and solid state batteries. She has published approximately 140 peer-reviewed papers on these and related subjects, many in ECS journals.

Statement of Candidacy

Electrochemistry has never been more relevant than today to solving the world’s grand challenges, such as global climate change and water scarcity. This presents a wonderful opportunity for ECS to reach out to the increasing numbers of researchers all around the world interested in solving these problems. While ECS has been my intellectual home since 1991, and ECS meetings and publications the first resources I tap into to keep up with my field, some researchers may not be aware of all that our Society has to offer. It’s my goal to help ECS reach out to electrochemists of every stripe—young and old, those in industry, academia, and national labs, everywhere around the world. The Free the Science campaign, with the ultimate goal of making ECS journals platinum open access (i.e., with no author processing charges), is a step in the right direction. We should continue to modernize our approach to make ECS journals appealing places to publish to all members and those contemplating membership. Likewise, the programs at ECS meetings have always been excellent and attendance is growing. To continue this upward arc, we should assess what gaps there are and try to fill them; for example, how can we generate content that appeals to industry as well as academia?

Statement of Candidacy

Advancing science and technology is not just the mission of The Electrochemical Society—it should be the goal of every scientifically educated individual. In the past century, ECS has achieved its goals through encouraging research, dissemination of knowledge, and the education of its members. Education in Science, Technology, Engineering and Mathematics (STEM) of generations to come is a crucial pillar of our societal responsibility.

With a network of over 8,000 scientists and engineers, ECS is invaluable for enriching people’s scientific and professional career. Expanding this membership base on a global level, leaving many opportunities for active participation by young, as well as established researchers from traditional and emerging countries should be our target.

We should use our tools for dissemination of knowledge efficiently. Our vibrant conferences should further expand globally and bring science to the people, such that the world has access to updated knowledge and international experience. It is important to maintain and strengthen our publication pillar by raising the impact factor through definition of focus areas, critical reviews, and contributions by the leaders in technological domains. Pivotal in this are our publications and the pioneering role played by Free the Science. Only by opening and democratizing research can science more rapidly advance society.

Sustaining further growth in ECS membership is crucial, yet it is equally important to make sure that our members feel engaged with the Society. Encouraging members to participate in conference organization, rewarding outstanding achievements, and bringing together technical experts to discuss emerging and established research will maintain the Society at the forefront of electrochemical and solid state science and technology for many years to come. Strong leadership is a prerequisite to develop content and innovativeness in a changing world, and if elected president, I will serve ECS and its members to the fullest of my capacities. Thank you for your consideration of my candidacy.

Statement of Candidacy

One of the things that makes me most excited about electrochemical and solid state science and technology is that it is a core platform that has applications in different aspects of our life. While exciting, there is still a lag in education about what electrochemical technologies can do. I believe that the ECS, being the premier solid state and electrochemical science and technology society in the world, will lead a paradigm change mitigating such an educational gap while enabling sustainable education in the field. If elected, I will lead the ECS to expand into programs that can explain to different audiences the importance and the fundamental principles of electrochemistry. For example, programs targeted to the next generation of scholars (STEM), industry, policy makers, and investors. During the biannual meetings, we could find opportunities for all this.

Outreach programs can become a continuous event in our ECS biannual meetings to attract the next generation into electrochemical science. Such programs could include our ECS student chapters. Forums and sessions that discuss commercialization aspects of electrochemical-based technologies can become part of our programs and can help reach out to funding agencies, policy makers, and investors. I will help facilitate joint collaborations between the ECS, federal funding agencies, and industry to organize and sponsor symposia on topics regarding frontiers and opportunities for electrochemical technologies.

I am fully committed and supportive of the ECS Free the Science effort. If elected, I will work with the ECS and members to raise the resources to minimize the costs burden of open access. It is important to continue to attract young authors to submit their best papers to our journals and to support rising stars in electrochemical and solid state science. If elected, I will help generate resources to increase the number of awards for young authors. In addition, I think it is essential to consider dissemination of knowledge to attract the next generation and to engage industrial and policy makers. With that respect, education-based apps can play a significant role. I will seek partnerships with our members and industrial sponsors to develop such opportunities.

I applaud the ECS diversity statement; the symposium on diversity and inclusion at the ECS Atlanta is an example of many other initiatives that can continue.

I will lead the ECS to implement the best practices in diversity and inclusion and to seek collaboration with other professional organizations to support these efforts.

The ECS is an integral part of my professional career, it is my family, in which I was accepted and welcomed since I was a student, interacting since then with many distinguished scientists all over the world that today have become my peers and friends.

It is an honor for me to be nominated for this position. I am looking forward to growing the ECS family and serving all of you.

Adam Z. Weber (continued from page 20)

the Science. Such efforts include increased recognition, publicity, and visibility of member accomplishments (including student chapters); creation of defined honorary symposia; formation of opportunities related to industrial interactions and career guidance with technical and nontechnical masterclasses; and outreach towards the younger scientists across the globe, where an award symposium will be established.

We are at a crossroads in terms of metricdriven research and short-term technology versus sustained scientific innovation and open access. I plan to enhance the Journals’ trends of focus issues, perspectives, opinions, and reviews by launching a series of ECS branded publications (including possibly dynamic publishing through ECSArXiv that leverages today’s internet resources) to emphasize those aspects upon which we have core domain knowledge and expertise.

I have a deep love for The Electrochemical Society, as it is not only my scientific home, but also a family. It is a rare institution that knows no strong discipline boundaries and involves a melding of industrial, laboratory, and academic researchers. If elected, it is my intention to expand upon this strength by welcoming and increasing diversity throughout our ranks. This is something that I believe in strongly as witnessed by my own research group. I plan to grow the membership of younger scientists and others through leveraging our strong reviewer pool and meeting attendees. Being a National Laboratory scientist and working at leadership positions within different large research efforts affords me a perspective of the opportunity presented when one crosses between science and engineering and academia and industry.

These are key traits of ECS that should be heralded and emphasized. Having served on various ECS committees and symposia and speaking to the membership candidly, I understand what needs to be done. It is an honor for me to be nominated for the vice president position, and if elected, I plan to serve ECS and its membership to the best of my abilities.

Marca M. Doeff (continued from previous page)

professional societies now have overlapping interests with those of The Electrochemical Society, but only we are the one-stop shop for electrochemical science—everything from water/energy nexus, batteries and fuel cells, photovoltaics, semi-conductors, corrosion, electrodeposition, and so on. This puts us in a very strong position. It’s an honor and a privilege for me to run for office of secretary of this venerable society, and, if elected, I’ll do my best to ensure the continuing success of ECS. Sannakaisa Virtanen (continued from previous page)

Statement of Candidacy

It is an honor to be nominated for the position of secretary of ECS. As an engaged, long-term member of this prestigious society, it would be a pleasure to further serve the Society and be actively involved in its future development.

Since my first ECS experience in Chicago 1988, the yearly ECS meetings became a standard entry in my calendar. Attending first as a speaker, then later as symposium organizer, section and division officer, as well as member of different committees, I had ample opportunity to interface with colleagues from different fields of electrochemistry. In turn, ECS had a strong impact on my professional development: the Society easily gives access to active participation and integration on virtually all society levels, allowing for the development of a strong, international professional network.

For me, ECS stands for electrochemistryrelated research and education in energy, sustainability, environment, and health— and other fields of key societal challenges.

Therefore, I would be glad to contribute to the near future of ECS in further promoting electrochemical research and education. As a past ECS division chair and member of the Board of Directors, but also as a university professor, I am convinced that professional networks, which trigger and foster critical scientific discussions, are the key for the progress of science.

As secretary of ECS I would do my best to serve its members, to maintain and nourish a platform to drive science at the forefront of electrochemical science and technology to tackle the grand challenges of our future.

236th Meeting Highlights

ver 2,525 people from 52 countries attended the 236th ECS Meeting in Atlanta, GA, October 13-17, 2019. Attendees chose from 52 symposia, with over 1,900 oral talks and 550 posters, of which 1,026 were student presentations.

Opening Reception The opening reception kicked off the meeting. Held in the Atlanta Hilton, the well-attended Sunday evening social event featured light snacks and an open bar. The lively event offered attendees many opportunities to network.

Plenary Session ECS President Christina Bock welcomed attendees to the meeting during Monday evening’s plenary session, an event that wrapped up the day’s technical sessions, honored award winners, and featured the meeting’s ECS Lecture.

Among those award winners, Bock congratulated distinguished Society award winners Shimshon Gottesfeld, recipient of the Olin Palladium Award of the Electrochemical Society, and John W. Weidner, recipient of the Carl Wagner Memorial Award of the Electrochemical Society. Gottesfeld was recognized for over 35 years of work in the field of polymer electrolyte fuel cells (PEFCs), which led to the production of outstanding R,D&E work by several teams of scientists and engineers.

“I believe ECS is recognizing the impressive advancements in this field of electrochemistry and, particularly, the scientists and engineers who enabled these advancements culminating in reduction to practice of 100 kW level PEFC power sources for electric vehicles (FCEVs),” said Gottesfeld. “I feel I am receiving this award for the community of key contributors to this field of electrochemistry, and I am honored to represent them here.”

Weidner was recognized for the development of mathematical models that predict the behavior of electrochemically active materials, fuel cells, electrolyzers, and batteries, which aid in the design and operation of electrochemical systems, particularly to better understand the effect of volume change on the behavior of batteries.

ECS President Christina Bock presented the opening remarks at the 236th ECS Meeting.

“There are many models in the literature that can predict the electrochemical performance of batteries (e.g., voltage versus time) under a variety of operating (e.g., current) and design (e.g., electrode thickness) conditions. However, existing models do not consider how stresses can build up in the system as the expanding porous electrode is being constrained by the battery casing,” said Weidner, whose predictions show the dimensional and porosity changes in a porous electrode caused by volume changes in the active material during intercalation.

Bock and ECS Executive Director and CEO Christopher Jannuzzi went on to present awards to the 2019 Class of ECS Fellows: Joseph Wang, Yushan Yan, Paul J. A. Kenis, Hubert Girault, Masayoshi Watanabe, Alison J. Davenport, Yang-Kook Sun, Takayuki Homma, Vito Di Noto, Thomas J. Schmidt, Larry Nagahara, Mike Perry, Flavio Maran, Jun Liu, and Alok M. Srivastava.

Bock thanked the meeting sponsors and ECS’s institutional members for their continued support and commitment to ECS.

The ECS Lecture Valerie Browning has served as the director of DARPA’s Defense Sciences Office (DSO) since December 2017. She has over 35 years of experience in managing and executing defense-related research and development (R&D).

Her ECS Lecture, “DARPA Advances in Electrochemistry and Solid State Science and Technology,” provided insight on how DARPA programs—created to produce breakthrough technologies and capabilities for national security—are generated and future areas of interest that might be on the horizon.

“DARPA’s relationship with the R&D community has been and will continue to be crucial in achieving breakthrough innovations.

It is important that researchers interested in supporting the DARPA mission understand how the agency works and how to engage our program managers in order to continue to build and support a healthy R&D ecosystem for national security,” said Browning. (continued on next page)

Next Generation Electrochemistry 2019: Diversity in Electrochemistry The Electrochemistry Society Chicago Section and the University of Illinois at Chicago (UIC) hosted the fourth edition of Next Generation Electrochemistry (NGenE) from June 3-7, 2019. Nine worldrenowned experts and 37 advanced graduate students and postdocs discussed research frontiers in electrochemistry. NGenE faculty delivered a high-level overview of the current body of knowledge and highlighted critical gaps preventing transformative advances.

Applications of electrochemistry in scientific fields from batteries to the detection of neurological processes were covered. The overarching message was that solving certain fundamental questions could impact a notable number of diverse fields and create opportunities for crosspollination of approaches between fields. They also discussed the

most modern approaches to understanding electrochemistry. Lectures were supplemented by demonstrations of cutting-edge tools such as UIC’s in situ electron microscopy, and a one-day visit to the Argonne National Laboratory. Participants networked at social events, a discussion of careers in electrochemistry, and a poster session.

Working in teams, students developed a document and presentation describing their perception of the most crucial question facing future generations of electrochemists. NGenE 2019 was sponsored by BioLogic USA and Garmy Instruments, and endorsed by ECS and the Materials Research Society.

The organizing team is looking ahead and planning NGenE 2020, scheduled at UIC from June 1-5, 2020. Contact the program director at jcabana@uic.edu to provide your input in shaping the critical features of the program, which focuses on fundamental aspects of electrochemical science.

Staff News Mary Beth Schwartz joined ECS as Publications Specialist/Interface Production Editor in September 2019. In this role, she is responsible for the production and dissemination of Interface consistent with ECS goals, objectives, and policies. She will provide assistance in the management of ECS Publications by performing various duties related to journals/ECST production and data collection and analysis, specifically with respect to publications usage statistics. What inspired Mary Beth to work at ECS was her love of science, writing, and the rich history of the Society.

Mary Beth has a strong and varied experience in publishing. It all began with her own class newspaper in elementary school. At Kutztown University, her alma mater, she wrote for the student paper. Soon came a bridal magazine internship, stringing for local newspapers, and a break in corporate communications for New York Life Insurance. She traded the train ride to Manhattan for pumps, valves, and flowmeters with the monthly engineering publication Flow Control. For the next 15 years, Mary Beth managed home and garden magazines, construction industry pubs, and regionals. Today you can find her busy at her desk writing features, blogs, Facebook posts, and web content.

Beth Craanen, director of publications said, “We are thrilled to welcome Mary Beth to the ECS team. She brings a background and experience critical to advancing the goals and priorities of our magazine. I’m excited to see what she’ll bring to ECS publications as we look to the future.”

Yue Kuo Visits Cape Town, South Africa Former ECS President (2018-2019) Yue Kuo visited Cape Town, South Africa in August to attend the International Society of Electrochemistry (ISE) Conference and meet with ECS Cape Town University (CTU) Student Chapter members. At the ISE conference, he met many ECS members—including past and present officers— who are active members of both societies. Many meeting participants were from Eastern and Central European countries. Kuo invited these attendees to join ECS meetings; however, many felt the U.S. was too far of a travel destination.

Kuo met CTU Student Chapter members and faculty at the ISE meeting and during his visit to the university campus. CTU has large electrochemistry research centers. The chapter members were very interested in his presentation at the university on ECS’s history and current status. He also discussed his own research, introducing solid state science and technology to members who do not have access to this kind of research, but do have some activities using similar concepts. The participants were excited and appreciated the visit very much.

The UCT Student Chapter is planning a topical conference on hydrogen-related electrochemistry. Kuo encouraged them to apply for ECS technical sponsorship, which would allow them to include the ECS name and logo on their program. ECS also would help them promote the event.

A lot of excellent South African research is not well known because it is so far from the American continent and Asian countries.

For example, their coal-related energy research, metallurgy, and mining work are world class. Electrochemistry is critical to these fields. The world’s first heart transplant was performed at Groote Schuur Hospital in Cape Town. Kuo sees many opportunities for ECS involvement in conferences on related topics—and the opportunity to recruit new members in the region.

Renewal Reminder ECS encourages institutional members to renew their membership before the end of 2019. The institutional membership program provides academic, government, and industry partners access to research and the ECS community. Program benefits also include discounts on subscriptions, along with advertising, sponsorship, and exhibiting discounts for ECS biannual meetings.

ECS’s 50 institutional members have more than 300 member representatives. These representatives receive all ECS member benefits, including access to the ECS Digital Library and member pricing.

In Memoriam memoriam Robert P. Frankenthal (1930 – 2019)

R

obert P. Frankenthal passed away on September 18, 2019. On that day, The Electrochemical Society lost one of our best.

Bob Frankenthal was born in Berlin, Germany on September 11, 1930. He and his parents left Berlin in December 1938 to start a new life in New York City. Adapting to a different culture with a different language was challenging for his family. Bob’s focus on his education through his youth served him well in the years to come. In 1948, he journeyed to upstate New York to attend the University of Rochester where he received his BS in chemistry in 1952.

An early indication of Bob’s good judgement and his willingness to stake out new territory was his decision to become the first graduate student of Professor Irving Shane at the University of Wisconsin.

Shane’s research in electroanalytical chemistry and his management skills eventually led him to become the chancellor of the University of Wisconsin. Bob’s doctoral thesis was on diffusion currents at spherical electrodes. I was privileged to hear several lectures by Professor Shane on that work 12 years later when I was a graduate student at the University of Wisconsin. I had no idea at the time who Bob Frankenthal was, but I clearly recall how much I enjoyed those lectures. Years later when I was preparing remarks for a Symposium in Bob’s honor on the occasion of the Centennial Meeting of The Electrochemical Society in Philadelphia, Professor Shane shared with me, “It was a pleasure to have a bright, enthusiastic, creative person as my first graduate student, and he certainly set the bar for all who followed.” Bob loved to share stories with his close friends about his time in Professor Shane’s group. Bob received his PhD in 1956.

From Madison, Wisconsin, Bob moved on to Monroeville, Pennsylvania, where he joined the Applied Research Laboratory of U.S. Steel to work on corrosion of tin and tin plate. The success of that work led to his transfer in 1960 to U.S. Steel’s E. C. Bain Laboratory for Fundamental Research. There he carried out pioneering research on the passivity and localized corrosion of ferrous alloys, the mechanisms of electrode reactions, and the application of new surface analytical techniques to corrosion research. He was the first to precisely characterize the potential region of the active-topassive transition of stainless steels and the charge equivalent of the amount of passive film formed as a function of potential and time of passivation. Bob and Howard Pickering carried out original work on the breakdown of passive films and the propagation of pits. They were the first to demonstrate by chemical analysis that hydrogen was evolved from pits even when the surface was potentiostated at +1.2 V(SCE).

After joining Bell Laboratories in 1972, Bob expanded his research and engineering work to include atmospheric corrosion, gaseous oxidation, protection of surfaces, and reliability of electronic materials and devices. Much of his outstanding work was related to improving the reliability of materials and devices important to telecommunications equipment. Unfortunately, only those who had the privilege of working directly with Bob where able to appreciate the quality of that work. His ability to find quantitative ways to understand and explain complex phenomena leading to materials

failures was remarkable. In parallel with supporting this engineering work, Bob moved in new directions with his research including: (1) inventing a Cr/Nb duplex coating that prevents natural oxidation that would catastrophically degrade the magneto-optic character of these materials; and (2) showing that processing related corrosion of TiN/ Al/TiN metallization being used in silicon integrated circuits is caused by galvanic effects. Bob’s extensive contributions to science and to Bell Laboratories resulted in his 1983 recognition as a Distinguished Member of Technical Staff for Sustained Achievement.

Over Bob’s career his research resulted in over 100 publications and eight patents. He was also editor or co-editor of seven volumes related to corrosion and reliability of materials. For many years following his retirement from Bell Laboratories in 1996, Bob continued his daily routine of coming to work to support his colleagues in whatever way he could. He was always driven to understand a problem, find a practical solution, and enjoy the pleasure of a job well done. The high esteem his colleagues have for his research is evident in the many honors he received including the H. H Uhlig Award in 1989, Fellow of the National Associate of Corrosion Engineers in 1994, Fellow of The Electrochemical Society in 1995, and the Whitney Award in 1997. He also served as the Corrosion Division editor for the Journal of The Electrochemical Society for 12 years and was chair of the Gordon Conference on Corrosion in 1970.

To those who worked with Bob every day, he was much more than an outstanding scientist. It was my good fortune to join the same department at Bell Laboratories as Bob, one week after he did.

I may not have been the first young scientist Bob mentored, but I immediately knew he was someone I wanted to be around as much as possible—and it turned out to be for three decades. His thoughts were offered with grace, compassion, and clarity. He cared deeply about all his close colleagues at Bell Laboratories. He made all of us better and improved the quality of our work. He was always ready to serve others no matter the need, including helping with more mundane activities when colleagues were spread too thin.

The same qualities that marked Bob’s time at the E.C. Baine Research Laboratory and at Bell Laboratories extended to his love for and support of The Electrochemical Society for over six decades.

His many thousands of volunteer hours given to the Society over those years and his legacy gift exemplify how much he cared about the Society. He was the same person whether he was supporting the day to day functioning of the society or providing leadership. His leadership included serving as chair of his local section in 1963, the Corrosion Division in 1980, and numerous committees including the Centennial Meeting Celebration Committee. He was president of the Society in 1993. In recognition of his service, he received the Acheson Award for Science and Service in 2004, and in 2016, he was featured as an ECS Master.

Bob lived his life seeking to support others and to contribute to the betterment of every activity he joined. His family, his colleagues, his employers, and The Electrochemical Society were the beneficiaries.

He kept his commitments, no matter how challenging, both in his work and in his family life. Thank you, Bob. What a model your life has been for all of us.

Social Media Platforms for Electrochemistry

by Edwin Khoo, Matthew J. Lacey, and Steven C. DeCaluwe

W

hile social media is increasingly used for social interaction and information dissemination, it remains underused by researchers for professional development and networking (science inreach) and science communication (science outreach). This situation is unfortunate because social media can offer a more frictionless way of interacting with other researchers and the general public1 compared to traditional communication tools such as email.

Talking on Twitter Twitter is probably the most common social media platform used by researchers for initiating conversations on research and academia. The barrier to entry to Twitter is low and only involves account creation. Any Twitter user can make public posts (i.e., “tweets”), directly start a conversation with other users using the “@” symbol, and send private direct messages to other Twitter users.

Twitter lists and hashtags are effective tools for managing these posts and conversations along common themes. For example, Dr. Matthew Lacey curates a list2 of battery scientists active on Twitter, which, at the time of writing, aggregates tweets from 124 members and has 113 subscribers. At the 235th ECS Meeting in Dallas, Texas, the #235thECSMeeting, #ECS235, and #ECS2019 hashtags were used to organize and facilitate searching of conference-related tweets. Dr. Steven DeCaluwe also used Twitter to share talk details before the conference, “live tweet” (summarize, share highlights, and promote) talks during the conference, and organize an in-person meet-up of roughly 10 conference attendees on one night of the conference.

Conferences present an incredible opportunity for researchers across various career stages to network and share their work; Twitter represents an increasingly powerful way to amplify both of these.

Additionally, for those unwilling or unable to attend conferences, social media platforms, such as Twitter, can provide a low-barrier supplement to conference functions. Users can follow and interact with other researchers in the field in a less formal environment, promote and discuss their own and others’ research, form collaborations, and follow live tweets of conference talks, without the financial, social, or environmental pressures, which can sometimes accompany traditional conference participation.

Some Twitter accounts, such as @realscientists,3 exclusively focus on science outreach where researchers describe their work and answer questions from Twitter users. For instance, Dr. Matthew Lacey curated tweets under this handle for one week to discuss his battery research at Uppsala University.4 Institutional Twitter accounts, such as ECS’s @ECSorg5, also play an important and synergistic role in communicating news and the latest research to a broad and diverse audience that may be different from the audience that individual authors’ Twitter accounts attract.

Reaching Out on Reddit Besides Twitter, there are other social media platforms that are useful for science communication.

Reddit is a popular content aggregation site that is organized around communities called subreddits that share common interests. For example, the r/science subreddit6, which has about 23 million members and is one of the largest online communities for science outreach, focuses on moderated discussion of the latest peer-reviewed scientific research. It also organizes panel discussions where the community asks questions that are answered by scientific experts. Recently, Dr. Edwin Khoo and several r/science moderators organized a panel discussion7,8 on batteries and energy storage that attracted many high-quality questions that were comprehensively answered by invited experts, namely Prof. Kristin Persson, Prof. Shirley Meng, Dr. Raymond Smith, Dr. Matthew Lacey, Prof. Venkat Viswanathan, and Prof. Daniel Steingart.

One possible reason why these social media platforms are not as popular as they should be among researchers is that the metrics for research productivity do not typically include such public outreach activities. However, this outreach is critical to one of the core missions of research to effectively communicate research results to the general public, whose tax money funds a large portion of academic research, and therefore should be highly valued. While there is significant variation in how different communities use social media such as Twitter9, robust Twitter communities have grown organically in the biomedical10, geoscience,11 and chemistry12 fields.

In electrochemistry, we the authors feel that Twitter and Reddit have served us well in performing science inreach and outreach. Intangibly, it has directly fostered a sense of community among researchers in the field, and provides another avenue to learn about and share research updates with the public. More tangibly, we have benefitted from the broad audience afforded by social media to connect more directly to journalists, journal editors, and professionals in other sectors.

Moreover, services, such as Altmetrics, provide social media and attention scores for a given research work, such as papers and talks.

Going forward, it will be of interest to see if and how such metrics correlate with the traditional, citation-based metrics which they complement. ECS has already played a prominent role in rethinking the future of open access publishing with its Free the Science initiative. We feel that the society can similarly take a leadership role in promoting the use of social media for science outreach. Concrete steps, such as allowing authors to publish social media handles along with other contact information and using its social media influence to more directly highlight and connect members on social media platforms (for example, the @ECSorg Twitter account has over 1,900 followers at the time of writing), can help shape the way societies in general use social media to provide value to their members. We hope that the community will continue to embrace social media, and look forward to the ways in which social media can continue to connect researchers and help spread information about the important work of our society’s members. © The Electrochemical Society.

Looking at Patent Law:

Patenting a Process for Making Fullerenes– A Case Study

by E. Jennings Taylor and Maria Inman

I

n this installment of the “Looking at Patent Law” articles, we present a case study of one of the early patented inventions for making fullerenes. We have chosen this invention to align with the focus of this issue of Interface on The Electrochemical Society Nanocarbons Division.

Recall from our previous article,1 the prosecution history of a patent application is publicly available in the file wrapper on the U.S. Patent & Trademark Office (USPTO) Patent Application Information Retrieval (PAIR) system.2 With the PAIR system as the primary source of information for this case study, we illustrate the prosecution “events” encountered leading to the issuance of U.S. Patent No. 5,227,038, “Electric Arc Process for Making Fullerenes”.3 Richard E. Smalley of Rice University is a coinventor on the ‘038 patent. Three years after the issuance of the patent, Prof. Smalley along with two of his colleagues, received the 1996 Nobel Prize in Chemistry for their 1985 discovery of 4

individuals. During his Nobel Lecture on December 7, 1996, Prof.

Smalley expressed “sadness” that only three of the group could be recognized and noted5 “… Every one of the people in that photograph was critically involved in the discovery (with the exception of the woman walking in the back) …”

During experiments directed towards understanding the formation of long chain carbon molecules in interstellar space, the collaborators discovered an extremely stable spherical carbon structure consisting of 60 atoms. The authors consulted the work of R. Buckminster Fuller to identify spherical shapes which would satisfy the valence “… new forms of the element carbon–called fullerenes–in requirements of the carbon atoms.7 Based on Fuller’s work, the which the atoms are arranged in closed shells …” authors suggested the C60 structure was a truncated icosahedron 5 In Fig. is a picture of the research containing 12 pentagonal faces and 20 hexagonal faces and named that discovered the Fig 1. The Rice1 University research groupgroup that discovered fullerenes. the molecule Buckminsterfullerene. Fuller was a twentieth-century fullerenes on September 11, 1985, the day before they submitted their visionary who worked across multiple fields, such as architecture, manuscript to Nature.6 The collaborators pictured are: standing, R. design, engineering, science, and geometry with the goal of creating F. Curl and kneeling from left to right, S. C. O’Brien, R. E. Smalley, a sustainable planet. He pursued innovative technology that could H. W. Kroto, and J. R. Heath. While the group consisted of five do “more with less.” One of his most intriguing inventions was the collaborators, Nobel prizes may be shared by no more than three geodesic dome, a lightweight structure that can enclose more space without the need for intrusive supporting columns.8 As depicted in the Nature manuscript, this structure may be represented as a soccer ball (Fig.2).

In Fig. 3 are key figures from the ‘038 patent depicting C60, C70, and C84 fullerenes. As of September 2019, the ‘038 patent had been cited by 253 subsequently filed patents or patent applications. The 1985 Nature article has been cited 11,670 times.9 In 2006, the Nanocarbons Division of the Electrochemical Society established the Richard E. Smalley Award to recognize contributions to the understanding and applications of fullerenes and “… to encourage excellence in fullerenes, nanotubes and carbon nanostructures research …” (continued on next page) Fig. 1.

are defined by their use in the specification. Furthermore, the inventors are permitted to be their own lexicographer16

Upon Richard Smalley’s passing in 2005, the U.S. Senate offered its condolences and passed a resolution crediting him as the “Father of Nanotechnology.”10

“An applicant is entitled to be his or her own lexicographer … [even by] setting forth a definition of the term that is different from its ordinary and customary meaning(s).”

Utility Patent Application

The utility patent application contained claims directed towards one statutory patent class, a method (for making fullerenes).17 An exemplary independent claim18,19 from the patent application illustrating the method statutory class is

On October 4, 1991, a utility patent application titled, “Electric Arc Process for Making Fullerenes” was filed by attorneys representing William Marsh Rice University on behalf of inventors Professor Richard E. Smalley and Robert E. Haufler, a predoctoral fellow.

Note, the Nature article used a Nd:YAG laser to form fullerenes by vaporization of carbon from the surface of a graphite disk in a helium atmosphere. The patent application described a process for forming fullerenes by vaporizing carbon using an electrical arc and then recovering the fullerenes from the condensed soot.

Recall, in order to establish a filing date, a utility patent application must include, at the time of filing 1. Specification 11 “… a written description of the invention, and the manner and process for making it…to enable any person skilled in the art … to make and use [the invention] …”

2. Minimum of one claim12 “… particularly pointing out … the subject matter … as the invention …”

3. Drawings13 “… where necessary for understanding the subject matter … to be patented …”

In order to maintain the filing date, the following additional material must be submitted: 1. Filing fee in accordance with the current USPTO schedule14 2. Inventor oath or declaration asserting15 a. The patent application was authorized by the inventor(s), b. The inventor(s) believe he/she is the original inventor or they are the original joint inventors.

The subject patent application included a specification, claims, drawings, and the filing fee. Consequently, the requirements to establish a filing date as described above were met.

The specification included a description of the prior art, problems within the prior art, a summary of the invention describing various and description 1985 Naturethearticle. embodiments of thefrom invention addressing prior art problems, and a detailed description of the invention with examples of generating and recovering fullerenes using the apparatus shown in Fig. 4. The meaning of the terms used in the written description of the invention

Claim 1 (as issued from ‘038 patent). A process [method] for making fullerenes comprising: a. providing a carbon vapor generation zone which comprises a first electrode and a second electrode, b. maintaining the carbon vapor generation zone in an atmosphere consisting essentially of an atmosphere selected to form fullerene molecules, c. applying sufficient electrical voltage to the first electrode to maintain an electrical arc between the first electrode and the second electrode, d. providing a carbon source in close proximity to the electrical arc, so that the carbon source is heated by the electrical arc to form a carbon vapor, e. passing the carbon vapor to a fullerene condensing zone where the carbon vapor is condensed into a solid carbon soot, and f. recovering fullerenes from the carbon soot.

On October 31, 1991, correspondence from the USPTO assigned patent application number 07/771,741 to the utility patent application and issued a “Notice to File Missing Parts of Application/Filing Date Granted” with a two-month response date. The notice was directed towards the inventor oath or declaration as the patent application included all the other requirements to establish and to maintain the filing date.

On December 4, 1991, the applicants responded by filing an inventor declaration, power of attorney, and statement claiming small entity status. The declaration included a statement from both inventors stating, “… I believe I am the original, first and joint inventor with the other named inventor(s) of the subject matter which is claimed …”

As previously discussed, the “named inventors” must be correctly represented a depicting U.S. patent Fig 3. Figures from ‘038 on patent C60, , and C84 fullerenes.

C70Specifically, application.20 inclusion of a colleague as a coinventor who did not participate in the conception of the invention is known as a misjoiner and invalidates an otherwise valid patent.

Similarly, exclusion of a coinventor who participated in the conception is known as a nonjoiner and also invalidates an otherwise valid patent.

If an inventor is erroneously omitted or erroneously included as an inventor, the misjoiner/nonjoiner may be corrected and the patent remains valid.21 The power of attorney appointed registered patent practitioners from the firm Baker & Botts to “… prosecute this application and to transact all business in the United Fig. 3. Figures from the ‘038 States Patent and Trademark office patent depicting C60, C70, ­ and connected therewith …”

The treasurer of William Rice Marsh University filed a declaration claiming small entity status as a nonprofit university.22 Additionally, the response included the appropriate small entity filing fees.

Finally, the specification indicated that the government may have certain rights in the subject invention, specifically23

Fig 4. Figure from the ‘038 patent depicting the apparatus used in the examples to from fullerenes.

“Due to the inventor’s multiple funding agreements, applicants’ attorney is not, at this time, certain that this invention was made with government assistance … applicants reserve the right to strike the statement so indicating …”

Submission of an Information Disclosure Statement and Duty of Candor The attorneys for the applicants submitted an “Information Disclosure Statement” (IDS) in accordance with US patent laws. The IDS is the submission of relevant background art or information to the USPTO by the applicant. The “Duty of Candor” requires that the inventor submit an IDS within a reasonable time of submission of the patent application disclosing24 “… to the Office [USPTO] all information known to that individual to be material to patentability …”

The “Duty of Candor” is specific to any existing claim and requires that the IDS be continually updated while the claim is pending. The “Duty of Candor” ceases only when the claim is allowed and the patent issue fee is paid. As required by the USPTO, additional IDSs were submitted during the prosecution of the patent application as the applicants became aware of additional related prior art.

The “Duty of Candor” extends to any individual associated with the filing of the patent application including 1. Inventor(s), 2. Patent Counsel, or 3. Persons who are substantially involved in the preparation or prosecution of the patent application.

Substantial involvement could include technical assistants, collaborators, or colleagues. Substantial involvement would generally not extend to clerical workers. Furthermore, the inclusion of a reference in an IDS25 “… is not taken as an admission that the reference is prior art against the claims.”

If a finding of a violation of the “Duty of Candor” resulting in “inequitable conduct” regarding any claim in a patent application or patent is determined, then all the claims are rendered invalid.26 Finally, in spite of the requirement of the “Duty of Candor”, the applicant is cautioned not to “bury” the examiner with a long list of non-material references in hopes that the examiner will not notice the relevant material references.

Assignment On January 22, 1992, the inventors assigned their rights in the subject patent application to the William Marsh Rice University.

Non-Final Office Action (NFOA) On March 30, 1992, the USPTO issued a NFOA containing: 1. a notice to correct the drawings to be in compliance with USPTO standards, 2. the examiner’s search strategy for the subject patent application, 3. list of references cited by the examiner, and 4. a non-final rejection of the subject patent application.

For USPTO compliant patent drawings, the reader is referred to a guide to patent drawings published by NOLO Press.27

Fig. 4. Figure from the ‘038 patent depicting the apparatus used in the examples to form fullerenes.

The NFOA indicated a three-month period for response with the possibility of up to three months of extension with the payment of additional fees.28 If the response is not filed within this time period, the patent application becomes abandoned29 “… failure of the applicant to prosecute the application within six months after any [office] action … or within such shorter time, not less than thirty days … the application shall be regarded as abandoned by the parties thereto.”

All of the claims associated with the patent application were rejected based on anticipation (lack of novelty) in view of the prior30 and/or as being obvious in view of the prior art.31 On June 22, 1992, the attorney of record for the applicants conducted a telephone interview with the USPTO examiner to clarify some of the references cited as prior art in the NFOA.

Response to NFOA On June 30, 1992, the applicants responded to the NFOA and presented arguments regarding the anticipation and obviousness as well as amendments to the originally submitted claims.32 Because the response was filed within three months, an extension of time and payment of applicable fees was not required.33 In addition, the applicants submitted declarations to support the arguments in their response to the NFOA. There are generally three types of declarations/affidavits that may be submitted during the prosecution of a patent application: 1. Rule 130: To disqualify a disclosure as prior art34 “… by establishing that the disclosure was made by the inventor … [or] by establishing that the subject matter disclosed had … been publicly disclosed by the inventor …

2. Rule 131: To disqualify a commonly owned patent or published patent application as prior art35 “… patent owner may … establish invention of the subject matter of the rejected claim prior to the effective date of the reference …”

3. Rule 132: To provide evidence to traverse a rejection36 “When any claim … is rejected … any evidence submitted to traverse the rejection … on a basis not otherwise provided for must be by way of an oath or declaration under this section.”

Inventor Richard E. Smalley submitted a Rule 131 Declaration stating that the invention was “… reduced to practice [and hence conceived] in the United States by myself and Mr. Robert E. Haufler at least as of October 4, 1990 …”

(continued from previous page)

A similar Rule 131 Declaration was submitted by coinventor Robert E. Haufler. Recall, at the time of this invention, the United States patent system (pre-America Invents Act (pre-AIA)) was governed by “first-to-invent” in contrast to the current system governed by “first-inventor-to-file”.37 By asserting a date of conception, prior art references that were published after the conception date were removed as prior art. A declaration of this type is commonly known as “swearing behind” a reference. As noted in the statute, a Rule 131 Declaration requires “The showing of facts … to establish … conception of the invention prior to the effective date of the reference coupled with … exhibits of drawings or records, or photocopies thereof …”

To meet the “showing of facts” requirement, the declaration referenced a publication in the Journal of Physical Chemistry that was received by the editorial office on October 4, 1990. Finally, the declaration included an acknowledgement of the penalty for willful false statements “I acknowledge that willful false statements … are punishable by fine or imprisonment or both (18 U.S.C. §1001)and may jeopardize the validity of the application or any patent issuing thereon.”

This acknowledgement is required in declarations/affidavits submitted to the USPTO.

Final Rejection On September 15, 1992, the USPTO issued an office action rejecting all of the claims in the patent application. The final rejection was based on the written description requirement stating that the claims must38 “… enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same …”

Specifically, the examiner stated that the specification does not enable the step of selecting the atmosphere in the amended independent claim 1. In addition, the examiner rejected the claims based on the Doctrine of Inherency,39 stating “Because the process of the reference is identical to that claimed, fullerenes are inherently formed [by the process disclosed in the reference] and no distinction between the product … in the instant claim.”

Response to Final Rejection On February 8, 1993, the applicant and attorney of record conducted an interview with the USPTO examiner to discuss the final rejection. During the interview, the applicant discussed proposed declarations to overcome the enabling and inherency rejections derived from the two primary prior art references. The examiner interview was summarized in writing as “… Applicant presented data … showing that the presence of H2 is contrary and inimical to the production of fullerenes …

[In addition] Applicant detailed circumstances giving rise to confusion in the art regarding resistive and arc heating processes …”

An interview with the examiner40 “… does not remove the necessity to reply to Office actions …”

46

On March 8, 1993, the applicants requested an extension of time to respond to the final rejection and paid the appropriate extension fees. In addition, the applicant filed additional affidavits as discussed during the examiner interview.

A Rule 132 Declaration was submitted by Dr. James E. Butler, the Head of the Gas/Surface Dynamics Section in the Chemistry Division of the Naval Research Laboratory. Since Dr. Butler was not an inventor of the patent application, Dr. Butler qualified as a “disinterested party” and his assertions carried the appropriate weight of a non-biased party. Dr. Butler provided “expert” opinion that those skilled in the art would conclude that the prior art references described processes that would include hydrogen. Furthermore, the declaration included an acknowledgement of the penalty for willful false statements.

Richard E. Smalley submitted a Rule 132 Declaration with experimental data demonstrating that hydrogen had a detrimental effect on fullerene production. Smalley submitted another Rule 131 Declaration pointing out the erroneous assumptions in the examiner’s arguments that resistive and arc heating are the same processes. Both declarations included an acknowledgement of the penalty for willful false statements.

In addition to the declarations, the applicants presented amended claims for consideration by the examiner. On March 16, 1993, the attorney of record for the applicants conducted a telephone interview with the USPTO examiner and authorized the examiner to enter an additional amendment “… to more particularly point out the applicant’s invention.”

Allowance of Patent Application On March 18, 1993, the USPTO issued a notice of allowance for the patent application with the amended claims associated with the invention. After payment of the issue fee, the 07/771,741 patent application issued as U.S. Patent No. 5,227,038 on July 13, 1993.

Interestingly, a prior art reference was referred to the examiner by an outside party as permitted by the Code of Federal Regulations.

Specifically, during the period of patent enforceability, any person may file with the USPTO a written submission containing41 “Prior art consisting of patents or printed publications which the person making the submission believes to have a bearing on the patentability of any claim of the patent …”

The submission may be made anonymously42 and must include a certification that a copy was provided to the owner of the subject patent.43 The reference was in fact already considered by the examiner and had no bearing on the allowability of the patent application.

In most cases our synopsis of the prosecution of the ‘038 patent would conclude. However, at the time of this invention, the United States patent system (pre-AIA) was governed by “first-to-invent” and priority was awarded to the first party to conceive the subject invention. Specifically (pre-AIA), the first inventor to conceive, with the caveats herein, is entitled to a patent for the subject invention. In determining the priority of invention, an interference proceeding is conducted by the USPTO considering44 “… not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive …”

In addition to examining notebook records and other data corroborating the date of conception, the inventors had to present corroborating data demonstrating “reasonable diligence” from conception to reduction to practice in order to maintain the date of conception as the priority date of the invention. In order to demonstrate “reasonable diligence” from conception to reduction to practice the inventor must not have concealed, suppressed or abandoned the invention during the intervening time between conception and reduction to practice. If the first inventor to conceive is found to not have exhibited reasonable diligence after the date of conception, The Electrochemical Society Interface • Winter 2019 • www.electrochem.org

the priority date is moved to the later date when the inventor reestablished reasonable diligence towards reduction to practice.

An interference proceeding is conducted on a claim-by-claim basis, and the inventor with the earliest priority date is awarded the patent. The need for corroborating evidence as well as determining “reasonable diligence” added considerable uncertainty to interference proceedings. Consequently, interference proceedings were costly, complex and took a considerable amount of time and effort on the part of the inventors and USPTO. The uncertainty and complexity with the “first-to-invent” patent system were some of the reasons that the Congress passed the American Invents Act (AIA) to award invention priority to the “first-inventor-to-file”.

Patent Interference On October 19, 1994, the applicants were notified that an “… applicant is seeking to provoke an interference with your Patent No. 5,227,038.”

The interference was initiated by the inventors of U.S. Patent Application No. 07/930,818 titled “Method and Apparati for Producing Fullerenes” filed on August 14, 1992. Even though this patent application was filed later than the 07/771,741 patent application (October 4, 1991), the question regarding priority at that time (pre-AIA) was based on “first-to-invent”. On December 18, 1996, the USPTO Board of Patent Appeals and Interferences (BPAI) ruled that claims 10 to 12 and 14 to 15 of the ‘038 patent were not allowed. The other claims in the ‘038 patent remained valid. The ‘818 patent application subsequently issued as U.S. Patent No. 5,876,684 on March 2, 1999 (Table I).

The disallowed claims due to “first-to-invent” priority in the ‘038 patent were dependent on independent claim 1. Specifically, the dependent claims (10 to 12 and 14 to 15) further identified “providing a carbon source” (claim 1 element (d) reproduced above) as “graphite dust.” The corresponding independent claim from the ‘684 patent references the “carbon source” as “particulate carbon” (Fig. 5). The BPAI ruled that “graphite dust” and “particulate carbon” were legally equivalent and awarded “first-to-invent” priority to the inventors of the ‘684 patent. In effect, the ‘684 patent was awarded a dependent claim set from the ‘038 patent. Consequently, independent claim 1 of the ‘684 patent was dominated by claim 1 of the ‘038 patent and the owners of the ‘684 patent were not “free to practice” their invention without obtaining the permission of the owners of the ‘038 patent.45 To our knowledge, neither the ‘038 or ‘684 patents were successful commercially. In fact, most patents are not successful commercially, In addition, the owners of the ‘684 patent allowed it to become abandoned by discontinuing payment of maintenance fees.

A final note regarding the ‘038 patent is that it was not patenting the discovery of fullerenes. The discovery of fullerenes was published in the 1985 Nature article. Any patent regarding the discovery would have had to be filed within a year of the publication of the Nature article. In addition, the Nature article disclosed the use of a Nd:YAG laser to form fullerenes by vaporization of carbon from the surface of a graphite disk in a helium atmosphere. The ‘038 patent claimed a method for making fullerenes based on an electric arc.

Summary In this installment of our “Looking at Patent Law” series, we present a case study of the prosecution of U.S. Patent No. 5,227,038, “Electric Arc Process for Making Fullerenes”, invented by Richard E. Smalley and Robert E. Haufler. Smalley would subsequently win the 1996 Nobel Prize in Chemistry for the discovery of fullerenes.

Even so, the USPTO prosecuted the subject patent application without deference to reputation. The case study begins with a brief synopsis of the background of the invention followed by 1) filing of a utility patent application, 2) submission of Information Disclosure Statements (IDS), 3) traversing examiner rejection arguments via the submission of inventor and expert declarations/affidavits during the prosecution of the patent application, 4) the allowance of the patent, and 5) results from an interference proceeding. The case illustrates the requirement to submit an “Information Disclosure Statement” (IDS) and the associated “Duty of Candor” in interacting with the USPTO. The case additionally illustrated the use of affidavits to 1) present “new data” supporting the claimed invention to the USPTO (Rule 132 Declaration), 2) swear behind a prior art reference (Rule 131 Declaration), and 3) present expert opinion from “disinterested” parties (Rule 132 Declaration). The use of multiple declarations, examiner interviews, and written arguments with the USPTO indicates that perservance is often critical in the pursuit of patents.

In addition, the case illustrated the procedures for third parties to bring prior art to the attention of the USPTO and inventors, as well as a summary of the pre-AIA interference proceedings. With this case study, we hope to demystify the patent prosecution process and better prepare electrochemical and solid state scientists, engineers, and technologists to interact with their patent counsel regarding their inventions. © The Electrochemical Society.

t ech highligh t s The Influence of Electrolyte-to-Sulfur Ratio for Li-S Batteries Lithium–sulfur (Li–S) batteries are considered to be one of the most promising “beyond Li-ion” energy storage solutions for future devices; however, Li–S cells require further optimisation before their widespread commercialization can become a reality. One of the most influential parameters in Li–S battery performance is the electrolyte-to-sulfur (E/S) ratio. The E/S ratio has a strong influence on the polysulfide shuttle mechanism as well as the sulfur utilization percentage. Researchers from the Middle East Technical University and Bogazici University in Turkey have recently presented a 1-D electrochemical model to investigate the effect of E/S ratio on the electrochemical performance of Li–S batteries. The developed model suggests that increasing the electrolyte amount improves the cell voltage by linearly increasing the cathode exchange current density. The specific capacity and energy density are shown to increase in an E/S ratio range from 1 to 9 ml of electrolyte per g of S. However, above 9 ml/g the model predicts that the electrochemical performance of Li–S cells significantly deteriorates. This finding highlights how sensitive the Li–S system is as well as the influence of the E/S ratio on electrochemical performance.

4D Printing of Smart Stimuli-Responsive Polymers In 4D printing, the extra “D” refers to time over which a 3D-printed object transforms itself into another structure upon the influence of external energy input or stimuli. A common class of materials to enable such transformation is shape memory polymers that contain netpoints and switching segments, the former being chemical or physical crosslinks to maintain a temporary shape and the latter being crystalline or glass domains to provide elastic deformability such that a new shape can be achieved upon a stimulus. Many new developments on this new technology were published in a recent JES focus issue on 4D materials and systems. One example is a report by researchers from Politecnico di Milano of Italy. The authors devised a photocurable polymer formulation based on polycaprolactone methacrylates capable of memorizing a temporary shape and restoring to the original one by means of a thermal stimulus. More interestingly, a self-healing behavior was introduced into the system by incorporating ureidopyrimidinone methacrylates capable of forming multiple hydrogen bonds upon heating. The new material was successfully 4D printed with a commercial 3D printer. Both the shape

memory effect and the self-healing feature were demonstrated.

In Operando Analysis of Passive Film Growth on Ni-Cr and Ni-Cr-Mo Alloys in Chloride Solutions Passivation studies were recently performed by researchers at the University of Virginia, the Canadian Nuclear Laboratories, and Monash University to characterize the effects of single cations on the competing mechanisms of film growth and dissolution in multi-element alloys. Building off previously published literature, the authors utilized inductively coupled plasma-mass spectrometry (ICP-MS) and single frequency electrochemical impedance spectroscopy (SF-EIS) during anodic polarization to characterize the kinetics of these reactions on Ni-22 Cr and Ni-22 Cr-6 Mo (wt%) in both acidic and alkaline sodium chloride environments. In combination with these techniques, in-situ neutron reflectometry (NR) and ex-situ x-ray photoelectron spectroscopy (XPS) were used to validate the film composition as a function of time as determined by ICP-MS and to establish the chemical species present in the film before and after growth. Novel findings from these studies include the following: 1) the rapid formation of Ni and Cr-rich films in acidic solutions; 2) at longer times, the dissolution of Ni2+, which led to greater Cr3+ enrichment in the films; 3) the development of films of non-stoichiometric solid solutions formed via solute-captured cations; and 4) the enrichment of films with Ni2+ in alkaline environments due to the enhanced stability of NiO and Ni(OH)2.

Studies of Electrical Characteristics of Reduced Graphene Oxide Using Hybrid Mixture of Green Reducing Agents Graphene may be made via several routes.

For industrial scale, the oxidation of graphite, to form graphene oxide (GO), followed by reduction, to form reduced GO (rGO), was developed. Thermal or chemical reduction methods have been employed with differing benefits and outcomes.

Seeking alternative chemical reductants that are environmentally friendly yet effective, researchers in Malaysia investigated L-ascorbic acid (LAA) alone and mixed with glucose or trisodium citrate (TSC).

The authors characterized the various synthesized rGO samples via field emission scanning electron microscopy, four-point probe current-voltage measurement, and UV-Vis spectroscopy. Morphology revealed that the more reduced samples (subjected to LAA) were flake-like aggregates compared

The Electrochemical Society Interface • Winter 2019 • www.electrochem.org

to the curved/crumpled sheet shape of GO. All samples having had LAA in the reduction process exhibited absorption peaks centered at 265 nm, indicating full formation of rGO. The sheet resistance of LAA-reduced GO was approximately 10 times less resistive than that of GO, and had a conductance minimum close to 0 V (39 µV). rGO samples made via LAA/TSC and LAA/glucose exhibited the lowest sheet resistances (< 1 kΩ/sq); however, their higher conductance minima (> 60 µV) suggest the presence of functional groups.

Low-Temperature Fabrication of SolutionProcessed IGZO Thin-Film Transistors

by Three-Layer Gradient Diffusion The use of solution processing techniques within the semiconductor industry is generally focused upon the deposition of lithography resists and large-scale thick coated materials. One of the obstacles to further integration of solution processing techniques into large-scale manufacturing is the capability for more complex active material deposition. New processes are being investigated for the deposition of these active materials for use in modern electronic devices; In-Ga-Zn-O (IGZO) is one such material undergoing research for use in thin film transistors. To form devices with IGZO active materials, Chen et al. developed a solution processing deposition method combined with a threelayer gradient diffusion anneal. Due to this solution-based deposition technique, the formation of high quality IGZO thin films was achieved. The technique developed by these authors is a cost-effective method for the deposition of IGZO with an added benefit of a low temperature anneal. The lower temperature annealing allowed by the gradient diffusion means the thermal budget of the device is decreased. A decreased thermal budget means that the other layers in a device incorporating the IGZO do not see any additional high temperature annealing which could affect performance.

Nanocarbons Division: The Past, The Present, The Future

by Slava V. Rotkin

T

The Past

he Nanocarbons (NANO) Division is the youngest in The Electrochemical Society. Its history began with the first symposium on porphyrins and fullerene science, organized in early 1990s by Karl Kadish, Founding Chair of the Division. It was the time of the “gold rush” for carbon clusters: in 1991 the fullerene (a.k.a. buckyball) was named “The Molecule of the Year” and attracted a lot of attention in fundamental and applied science. In 1993 the Fullerenes Group was founded, shortly after the invention of CVD synthesis of buckyballs2,3,4,5—the production method which allowed easy access to this new allotrope of carbon. The long journey into the world of nanomaterials, with flat or curved surfaces, made of pure carbon, with hexagonal lattice similar to what Buckminster Fuller used for his geodomes, had begun. Zero-dimensional (ball-like) fullerenes, discovered in 1985 by Richard Smalley and earning him, Kroto, and Curl a Nobel Prize for this work, quickly became a building block of various composite materials, showed rich chemistry, physics, and optics. In 2006, the NANO Division Research Award named after Smalley was established. Following this cutting-edge science of fullerenes, the Division developed several symposia in the mid-90s.

Since 1995, a series of proceedings volumes (20+) on fullerenes and related materials was published by the ECS, each giving a slice of the state-of-the-art research in a certain area of science of nanocarbons.

At approximately the same time, another allotrope of carbon— cylindrical shell nanotubes7,8,9,10—was discovered by Sumio Iijima of NEC, the first recipient of the Smalley Award (2008), currently the member of NANO External Advisory Council, and Don Bethune of IBM. Following this new discovery, the Nanotube Symposium was organized and has been held for more than two decades since then.

Currently, the nanotubes, fullerenes, and porphyrins are the largest symposia of the NANO Division, attracting scientists from all over the world to annual spring ECS Meetings.

By the turn of the millennium, the Fullerenes Group grew and covered a large technical area that justified it becoming a full Division of the ECS with the original name “Fullerenes, Nanotubes, and Carbon Nanostructures,” later shortened to Nanocarbons Division. Indeed, nanoscale forms of carbon and related materials are not limited to buckyballs or tubes11,12,13. In the early 2000s, the family of zero-dimensional and one-dimensional carbon allotropes (fullerenes and nanotubes) was enlarged by adding twodimensional (2D) one-atom thick carbon sheets, commonly known as graphene14,15,16. Nowadays, the physics, chemistry, materials science, and applications of graphene and its derivatives are the focus of one of the NANO symposia, co-organized with a few other divisions. This symposium covers also a range of nanomaterials “beyond graphene,” such as transition metal chalcogenides, oxides/nitrides, polar atomic metals, and other 2D materials. All three allotropes of carbon will be discussed in the articles below.

The Present The NANO Division, with its main activity during the spring ECS meetings, brings 400+ abstracts annually that focus on the science and applications of nanomaterials. Six permanent symposia include: “Carbon Nanostructures for Energy Conversion,” “Carbon

Nanostructures in Medicine and Biology,” “Carbon Nanotubes—From Fundamentals to Devices,” “Fullerenes—Endohedral Fullerenes and Molecular Carbon,” “Inorganic/Organic Nanohybrids for Energy Conversion,” and “Porphyrins, Phthalocyanines, and Supramolecular Assemblies;” as well as one mega-symposium (co-sponsored with other divisions): “2D Layered Materials from Fundamental Science to Applications.”

In 2018, the Division established a new Focus Symposium series: NANO-Global, which is dedicated to one geographical region each year and presents a cross-national platform for scientists in the area of nanomaterials to exchange the latest results and enable collaboration links. Three forums have been organized thus far that feature NANO science from Republic of Korea, Latin America (Mexico, Brazil, Chile), and La Francophonie (France, Belgium, Switzerland).

Since 2019, the Division has held a special symposium, “NANOfor-Industry,” dedicated to practical applications of nanomaterials, bringing speakers from major U.S. funding agencies, and giving a podium to companies that produce or use nanocarbons to connect to the academic community. Currently, several industry representatives serve on the NANO External Advisory Council and provide financial support to strategic initiatives developed at the NANO Division.

The Future In 2018, the NANO Division received a major gift which allowed us to establish a new research prize named after Robert Haddon, the third recipient of the Smalley Award (2011). Annually, the recipients of the Haddon Award or the Smalley Award and the SES Award for Young Scientists, as well as a few keynote speakers of the year, give plenary-style lectures at the spring meeting. In addition, the four parallel sessions bring together a large group of invited speakers to mix with the students and young researchers, fostering the new generation of nanocarbon scientists. Thanks to the generosity of Division sponsors, nine NANO Awards are given every year for Best Posters, as well as multiple NANO travel grants to enable student attendances.

The research program of the Division is evolving and growing; in this issue of Interface the reader will find three articles that provide few vignettes of this activity. One article by Chen, Niu, Zhuang, Wang, Chen, and Yang, focuses on recent advances in the functionalization of fullerenes, the first carbon nanostructure, both endohedral (inside the cage) and exohedral (outside) functionalization. This article gives examples of contemporary fullerene science and what applications it can enable. Being concerned with applications, another area of growing interest in the NANO community is the biomedical use of nanocarbons. A second article by Antman-Passig, Ignatova, and Heller focuses on nanotubes as biosensing materials. Unique optical properties of nanotubes enable a rich and interesting physics, including the single photon emission and non-linear optical effects.

The functionalized nanotube may become a nanoscale biosensor, being excited and/or emitting in the near-infrared region, where the biological tissue is transparent. These novel materials have been already demonstrated for intracellular sensing and imaging, as well as for in vivo experiments. The third contribution focuses on the abovementioned 2D materials. When 2D layers of same or heterogeneous materials are stacked together, the property of the sandwich structure depends critically on the registry between the layers.

production of multilayered 2D-structures, especially those capable of scalable synthesis of 2D materials, and the characterization tools employed to control the synthesis have gained a significant amount of attention lately. The article by Rummeli, Ta, and Rotkin reviews most recent advances in this field.

The papers that constitute this issue cover a very broad area, which still represents just a small fraction of the scientific content to be found in the abstracts of the NANO symposia, available online17. If attending the meetings, besides technical content, one should enjoy other Division events, like the art exhibit, which happened in May, 2019 at the Spring Meeting in Dallas, TX18, presenting the paintings made with nanomaterials by the NY artist Joseph Cohen.

Exploring the Inner and Outer Spaces of Fullerenes

by Muqing Chen, Chuang Niu, Jiaxin Zhuang, Guan-Wu Wang, Ning Chen, and Shangfeng Yang Introduction

Endohedral Functionalizations

he first fullerene, C60, was discovered by the late Kroto, Smalley, and co-workers in 1985, and was named “buckminsterfullerene” based on its structural similarity to the Montreal biosphere designed by Fuller for the United States pavilion for the World Expo in 1967.1 Quite different to previously known allotropes of carbon like graphite and diamond, fullerene is the first molecular form of the elemental carbon with a closed-cage structure composed of a specific number of carbon atoms. Each sp2-hybridized carbon atom is bonded to three neighbors, creating hexagonal and pentagonal building blocks. For a classical fullerene C2n (Fig. 1a,b), the numbers of hexagons and pentagons are (n-10, n≠11) and 12 respectively according to Euler’s Theorem.2 It is the 12 pentagons that determines the curvature of the spherical molecule and thus are crucial for the stability of fullerene.

One of the most intriguing structural features of fullerene is its hollow interior, a sub-nanometer inner space offering unique opportunities to entrap atoms, ions, or clusters, creating the possibility of endohedral fullerenes. The first experimental observation of the possible formation of an endohedral metallofullerene (EMF) LaC60 was reported by Smalley et al. in 1985 soon after the discovery of C60,3 for which the lanthanide (La) metal atom was confirmed to be indeed in the endohedral form by the same group in 1991.4 The recognition of the unique electronic configuration of La3+@C823- (Fig. 1c), resulted from a three-electron transfer from the inner La atom to the outer C82 cage, substantially distinguishes EMFs as nondissociating salts from empty fullerenes like C60 with uncharged carbon cages.5 Such an intramolecular electron transfer is dependent on the nature of the metal and the type of entrapped species (metal only or metal clusters), and determines the stability of the EMF molecule. In particular, since in 1999 the serendipitous discovery of Sc3N@C80 containing an otherwise unstable Sc3N metal nitride cluster (Fig. 1d) which transfers formally six electrons to the outer C80 cage. Today, endohedral clusterfullerenes have become the most diverse and attractive subfield of fullerenes.6 In addition to the exploration of the inner space, the outer space of fullerene derived from the conjugated π skeleton is full of challenges and opportunities as well. Because fullerenes have closed-cage structures, on the cage there are no substitutable functional groups, thus the outer chemistry of fullerene is primarily focused on exohedral functionalizations via addition reactions accompanied with the breaking of C-C bonds within the cage.7 Given that there are formally 60 carbon atoms bearing 30 double bonds available for addition, exohedral functionalizations of C60 may potentially generate a large number of fullerene derivatives. Hence, understanding the addition patterns and ideally realizing selective synthesis affording specific major products are the key issues for developing fullerene chemistry. Moreover, some fullerene derivatives, such as [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and bisindene-C60 (bis-ICBA) (Fig. 1 e,f), have been successfully used as organic photovoltaics and in other applications.8-9 Herein, we briefly summarize the recent advances in both endohedral and exohedral functionalizations of fullerenes, demonstrating the mysteries of the inner and outer spaces of fullerenes. At the end we discuss the potential applications of fullerenes in a wide variety of fields.

To prepare EMFs, various synthetic methods have been developed including DC arc-discharging,10 ion bombardment,11-13 high pressure, and so on.14-16 In the most commonly used DC arc-discharging method invented by Krätschmer and Huffman in 1990, metal oxide/graphite composite rods are used as positive electrodes and then are arced in the direct current in a vacuum chamber filled with He and other reactive gas. The EMFs are generated along with carbon soot during this process, and organic solvents and various separation techniques are then used for the extraction and the isolation of the desired EMFs. Initially only metal ions were found to be entrapped inside fullerene cages. Early studies showed that all the rare earth metal ions from Scandium (Sc) to Lutetium (Lu) could be encapsulated inside fullerene cages with different size, in which M@C82 was the most commonly found form of this metallofullerenes.17 Moreover, two to three metal ions could be entrapped inside fullerene cages (Fig. 2).

EMFs with metal ions only were categorized as conventional EMFs, and the availability of this type of EMFs remained very limited in 1990s, due to its low product yield compared to the empty fullerenes.

A breakthrough of EMFs study occurred in 1999, when the formation of the unprecedented metal nitride clusterfullerenes (NCFs), Sc3N@C80, resulted from an accidental leakage of N2 into the reaction chamber, was discovered and confirmed by Dorn et al.18 Sc3N@C80 can be prepared with high product yield by introducing a small portion of nitrogen gas into the He atmosphere in the Krätschmer-Huffman generator during the arc discharging process. The yield of Sc3N@ C80 is much higher than the conventional EMFs and comparable to the empty fullerene C84. The high stability and unique electronic structure of Sc3N@C80 thus inspired the researcher to further explore the possibilities of stabilizing versatile metal clusters, combined by variable kinds of metal and non-metal atoms, by the fullerene cages. A metal carbide clusterfullerene (CCF), Sc2C2@C84 was then

Note that EMFs demonstrate much larger structural variety than conventional EMFs because the cluster structures are also changeable inside each type of EMFs, depending on the variable oxidation state of metal and the different number Fig. 2.

The structure of pristine empty The free radical reaction is one of the earliest developed methods fullerenes strictly obey the Isolated Pentagon Rules (IPR), which of fullerene derivatization. In recent years, free radical reactions suggest that in a stable fullerene cage, all the pentagons should be initiated by transition metals as copper salt have been reported to isolated by hexagons and adjacent pentagons pairs (APPs) are not afford versatile heterocycle fullerene derivatives.26 Fullerenyl cations stable.21 However, this rule has been broken by many non-IPR include fullerenyl radical cations and organofullerenyl cations, they EMFs, in which the charge transfer from the encapsulated species have received much attention in fullerene chemistry in recent years. In to APPs largely stabilized the non-IPR carbon cages.21 On the other this type of fullerene chemistry, C60 first formed the Fullerenyl cations, hand, novel metal clusters, which otherwise would not be obtained including fullerenyl radical cations and organofullerenyl cations, via by conventional synthetic methods, have been stabilized inside KOtBu or Cu(II) salts, which later were attacked by aryl boronic fullerene cages via the metal-to-cage charge transfer.

Electrochemical functionalization of fullerenes as a novel and powerful synthetic protocol has been widely used in recent years due to its mild reaction conditions, high regioselectivity and good yield. As shown in Fig. 4, in 2017, the bisadducts 12−14 of C6031 as well as bisadducts 15−16 and rare C70 δ-adduct 1732 were facily obtained via electrosynthesis by reaction 14 12 13 of dianionic C60QM2- and C702- with α,α′dibromo-o-xylene, respectively. Later, the Wang group reported the synthesis O of 1, 2, 3, 16-adducts of C60 derivatives N O 18 with different carbonyl groups from H 2 3 16 R a [60]fulleroindoline via regioselective 1 electrosynthesis.33 Subsequently the same group investigated the protonation behavior of the dianionic C60-fused δ-lactones 19 with 18 acetic acid. Unexpectedly, a retro Baeyer– 15 16 17 Villiger reaction, that is, conversion of the R R O C60-fused lactones to C60-fused ketones 20, O R 34 was observed in high yields. More recently, O O O they reported the benzylation of dianionic (a) C60-fused δ- and γ-lactones 19a and 21, achieving unexpectedly three types of ring+ 2e AcOH opened benzylated adducts 22-27.35 Ar Ar In traditional organic chemical reactions, most reactions require the use of a large 19 20 quantity of toxic and harmful solvents, which pose serious harm to the human health and O R' O R' environment.

Recently, the Wang group + achieved the reductive cyclization reaction O R' of C60 with enones, in the presence of zinc R' (b) O n n O and water under solvent-free ball-milling 24/25 22/23 conditions, and obtained a series of C60-fused O PhCH2Br + 2e cyclopentanols, which were subsequently O R' Ar Ar dehydrated to provide the corresponding C60-fused cyclopentenes.36 n Ph O H Open-cage fullerene derivatives, also 19a/21 TFA known as molecular containers, have been n = 1, 2 extensively studied for their wide range Ar of potential applications, such as selective capture of reactive intermediates, catalysis 26/27 within the cavity, and molecular transport.

The Gan group has been working on the preparation of open-cage fullerenes and Fig. 4. Electrosyntheses of fullerene derivatives. prepared a number of open-cage fullerene derivatives entrapping H2O2 and H2O clusters by the fullerene-mixed peroxide process (Fig. 5a, 5b).37-38 The Murata group reported the synthesis and properties of the paramagnetic molecular complex with the structure traping NO cluster shown in Fig. 5c, which was a stable substance both in solution and in the solid state.39 Very recently, they reported the synthesis of a new endohedral fullerene containing molecular H2O, and observed the olefin-H2O interaction in endohedral fullerene by single-molecule Fig. 5.

Exohedral Functionalizations of EMFs Recently, the Martín group employed 1,3-dipolar cycloaddition reactions of azomethine ylides on Lu3N@C80 and C60 to get the allfullerene C60-Lu3N@Ih-C80 electron donor–acceptor conjugates (Fig. 6a).37 The Yamakoshi group also used the Prato reaction to obtain

two bis-ethylpyrrolidinoadducts of Gd3N@Ih-C80 (Fig. 6b).41 Hirsch et al. innovatively grafted C60 and endohedral Sc3N@C80 to reduced graphene instead of the commonly used graphene oxide to form the graphene-fullerene hybrid structures (Fig. 6c).42 The hybrid structures unveiled the feature of covalent hybrid by combined measurements of statistical Raman spectroscopy, temperature-dependent Raman spectroscopy, as well as TG-MS and TG-GC-MS analysis.

also show that the temperature-derived reversible defunctionalization processes of hybrid Sc3N@C80 and graphene. This research provided evidence that the efficient synthesis of hybrid of Sc3N@C80 with graphene solves the long-lasting puzzle about the construction of carbon allotrope-only hybrid architectures.42 They also reported the covalent hybrid of Sc3N@C80 with the 1D-single-walled carbon nanotubes (SWCNTs) (Fig. 6d) by reaction of the negatively charged SWCNTs with the diazonium salt of Sc3N@C80.43 The successful covalent hybrid of the two carbon components is dependent on the reductive sidewall employing activated alkali metal nanotubides.

More importantly, covalent hybrid architecture was confirmed using a series of characterization similar above for graphene-fullerene hybrid, emphasizing the covalent nature between these two carbon allotropes. This research has widened the scope of inter-carbonallotrope hybrids into the areaway of redox-active metal complexes shielded in a protective all-carbon layer. 43

Summary and Outlook The peculiar electronic and chemical properties of EMFs provide great potential for the application of EMFs in various fields such as biomedicine,44-45 photovoltaic cells,46 and molecular devices, etc.47 Gd-based EMFs have been proved to be an efficient MRI contrast agent for breast cancer,48 and also shows potential for the cancer treatment.49 Recent systematic studies also show that EMFs have outstanding single molecular magnet (SMM) properties, which sheds light on its potential in future magnet storage devices.50-52 Single molecular device studies of Sc3N@C80 revealed that it is the first bi-thermopower material, which demonstrates its potential for application in the construction of functional molecular devices.53-54 Undoubtedly, EMFs present a fascinating molecular world, in which many new compounds with variable applications will continue to be prepared and analyzed. However, despite the great advances in the past three decades, the studies of endohedral fullerenes still 56

face the many questions. In particular, the low product yield and requirement of extensive HPLC processes for purifications remain as the major obstacles for its extensive fundamental materials studies and large-scale applications. Thus, in addition to the further exploration of their novel structures and fascinating electronic states, future research may also need to search for efficient and selective synthetic methods to make large quantities of EMFs available for fundamental studies and applications.

The functionalized EMFs not only possess better solubility in a wide range of organic solvents, but also exhibit optimized energy levels and bandgaps by reducing the number of delocalized π bonds, enabling their applications as electron acceptors and electron transport materials used in polymer solar cells and perovskite solar cells.55 For example, [6,6]-phenyl-C61-butyric hexyl este (Lu3N@C80PCBH) was applied as an electron acceptor combined with P3HT to construct bulk heterojunction polymer solar cells, achieving an open circuit voltage of 890 mV as well as a power conversion efficiency of 4.2 percent.56 The higher PCE of the P3HT/Lu3N@C80-PCBH devices relative to that of P3HT/PC61BM was attributed to the reduced LUMO, facilitating to capture more of the energy associated with each absorbed photon and leading to enhanced OPV performance through the improved Voc shown in Fig. 7a.56 More recently, another EMF derivative [Li+@C60]TFSI− was used as a dopant in spiro-MeOTAD and applied in MAPbI3-based perovskite solar cells, exhibiting comparable performance with that of conventional Li+TFSI−. More importantly, perovskite solar cells with [Li+@C60] TFSI− showed significantly higher stability relative to that of Li+TFSI-based devices, which was ascribed to the hydrophilic nature of the fullerene cage encapsulating Li+ and the antioxidant of Li@C60.57 In addition to the application in the energy fields, endohedral fullerene derivatives with multi-addition patterns have been developed and widely applied in biological and nanomedicine, including as MRI contrast agents, as well as anti-tumor and radiopharmaceutical treaments.58-59 Among them, the water-soluble gadoliniumThe Electrochemical Society Interface • Winter 2019 • www.electrochem.org

containing endohedral metallofullerenes as Gd@C82(OH)x is the most important one, featuring strong MRI proton relaxation in vitro/ vivo with antineoplastic activity of high efficiency and low toxicity (Fig. 7b).60- 62 Recently, the radical addition reaction of Dy2@C80 with benzyl bromide affords a novel Dy2@C80-(CH2Ph)adduct, in which an unpaired electron is trapped between dysprosium ions form a singleelectron metal-metal bond. Giant exchange interactions between lanthanide ions and the unpaired electron of Dy2@C80(CH2Ph) presents a single-molecule magnetism of record-high 100 s blocking temperature at 18 K (Fig. 7c). Meanwhile, all magnetic moments in Dy2@C80(CH2Ph) are parallel and couple ferromagnetically to form a single spin unit of 21 μB with a dysprosium-electron exchange constant of 32 cm−1.5 © The Electrochemical Society.

Carbon Nanotube Optical Probes and Sensors

by Merav Antman-Passig, Tetyana Ignatova, and Daniel Heller Photophysical Characteristics of Single-Walled Carbon Nanotubes

S

ingle-walled carbon nanotubes (SWCNTs) are pseudo one-dimensional1 (1D) allotropes of carbon; rolled-up sheets of graphene assembled into seamless cylinders. SWCNTs are composed of purely sp2 hybridized carbon atoms, responsible for their unique strength, stability, and electronic properties.2,3 These properties have been studied extensively for use in diverse applications, including composites and electronics/ computing. A smaller contingent of investigators, intrigued by the unique optical properties of SWCNTs, is developing nanotube-based optical sensors and imaging probes for biomedical applications.

SWCNT diameters are typically between 0.8 to 2 nm with lengths ranging from 100 nm to several microns long. Due to this large aspect ratio, SWCNTs are considered pseudo one-dimensional materials, an important molecular scale property for surface reactions.

SWCNTs exist as different chiral species, pictured as the direction of the imaginary rolled up graphene sheet. The chirality is defined by the chiral vector (Ch) indexed by integers n,m. (Fig. 1.a) This geometry imposes on the nanotube a periodic boundary condition, which leads to quantization of the allowed electronic states. Allowed states can either occupy the Fermi level, leading to the nanotube exhibiting metallic properties, or, if no allowed states occupy the Fermi level, the nanotube will be semimetallic or semiconducting. (Fig. 1.b) This boundary is defined by the (n,m) indices: if n-m is an integer multiple of 3 (n-m=3q, where q is an integer) then the nanotube is metallic, and otherwise it is semi-metallic or semiconducting. The range of electronic states of SWCNTs have led to many promising applications, however, for this review paper, we highlight the electrooptical properties of semiconducting nanotubes for use in biomedical applications. The 1D geometry of SWCNTs results in van Hove singularities in their density of states.

Optical transitions are specific to (n,m) chiralities, giving rise to absorption and photoluminescence features of semiconducting nanotubes at various energies.

The photoluninescence–fluorescence of dispersed SWCNTs was first described in O’Connell at el.4, and spectroscopic signatures for chiral species were identified soon after.5 SWCNTs can absorb a photon corresponding to the second van Hove transition (E22), and, following non radiative relaxation, emit a photon corresponding to the first van Hove transition (E11).

This process is especially important for biomedical applications, as the (E22) absorbance bands of SWCNTs are mainly in the visible range and extend into the near infrared (NIR-I) window of 750-900 nm. The emission bands of most SWCNT species are in either the NIR-I (continued on next page)

window or the 1000-1700 nm (NIRII) window. Both of these windows are promising for imaging and sensing applications in biological samples, due to low absorption and high penetration, reduced scattering and low autofluorescence of tissues in these ranges.6

Due to their unique properties, SWCNTs are now under intense investigation as NIR optical biosensors.

A molecular biosensor is an analytical tool which integrates a molecular recognition element and a transduction element. The primary goal of a sensor is to measure and produce a quantifiable optical response to an analyte of interest. Key features of ideal sensors include: (1) Quantitative response; a biosensor should produce an optical signal that is proportional to analyte concentrations allowing for accurate distinction between concentrations. (2) High analyte specificity; responses to the analyte of choice and resistance to non-specific responses to interferents.

This is especially important in complex biological environments where various biomolecules may interact with the sensor and mask specific binding.

Commonly, a sensing element will produce an optical signal triggered by an analyte binding to a bio-recognition element (i.e., antibody, enzymes, proteins receptors). (3) Sensitive response; a biosensor should generate a sufficient dynamic range in rsponse to physiologic concentrations range of the analyte.

SWCNTs exhibit important optical properties that may benefit optical sensors; in addition to absorbance and fluorescence within the “biological transparency window.”

These include large Stokes shifts and unique photostability with respect to photobleaching.7 Also, in contrast to most NIR organic dyes, there is little fluorescence intermittency (commonly called blinking), a disadvantage of quantum dot probes. Both of these parameters make SWCNTs advantageous for long term measurements.8,9 Additionally, SWCNTs have narrow linewidths, potentially enabling multiplexed sensing of individual SWCNTs simultaneously.8 (Fig. 1.e,f).7 The photoluminescence of carbon nanotubes is highly dependent on their immediate environment,10,11 facilitating the detection of many classes of bioanalytes. SWCNT optical sensors are often designed to include a biorecognition element non-covalently

adsorbed to the nanotube surface. Analyte binding events on the nanotube sidewall perturb their local electronic structure, yielding measurable changes in emission intensity and/or wavelength due to redox and/or solvatochromic sensitivities, (Fig. 2.a) even observed at the single-nanotube level.

Despite major advancements in SWCNT optical sensor development, several challenges remain. Controlling the quality and purity of SWCNTs is still a significant challenge, as well as producing large quantities of isolated nanotubes. Recent protocols for isolating individual SWCNTs have accelerated the development of SWCNT biosensors.12,13 A disadvantage of SWCNT optical probes is low emission efficiency, i.e., low fluorescence quantum yields.14 However, the modification of nanotubes to include controllable defects known as organic color centers has been demonstrated to increase quantum yield.15,16,A Toxicity and biocompatibility are also important issues to address with regard to the use of SWCNTs in biomedicine. Biocompatibility investigations have reached different conclusions, depending on SWCNT purity, physio-chemical properties, routes of exposure, aggregation/bundling, and chemical functionalization used in the studies.17–19,20 Recent investigations show low toxicities upon aqueous dispersion using protocols involving functionalizing SWCNTs with polymers and biomolecules to disperse them individually.21 Singlestranded DNA (ssDNA) has been found to form highly soluble hybrids with SWCNTs,12 and a few separation methods and optical applications have arisen as a result of this discovery.22–24,71,72 Noncovalent attachment of DNA,25 proteins,26 and polymers27 has led to SWCNTs constructs with demonstrable biocompatibility in living cells, plants, and animals.28,29 Non-covalent modification of SWCNTs has been used to first optimize solubilization in biocompatible solutions, and second to immobilize molecular recognition moieties.30–32 In the next section, we describe SWCNT-based nearinfrared optical sensor technologies, particularly in biomedical applications.

Probing Biomolecules Biosensors for biomolecule detection based on SWCNTs most commonly involve spectral changes of nanotube photoluminescence coupled to a molecular binding event. (Fig. 2.a) In most sensor incarnations, emission intensity modulation and/or wavelength shifting events are triggered by absorption of biomolecules on the nanotube surface. However, Förster resonance energy transfer (FRET), or excitation energy transfer, has been described in SWCNT-based sensors as well.33 Sensors for glucose,34,35 nitric oxide,36 hydrogen peroxide,37 avidin,38 neurotransmitters,39 and DNA conformational polymorphism (changes in DNA conformation)40 have been shown.

Notably, hydrogen peroxide is a redox-active molecule that induces quenching of SWCNT fluorescence.41 The detection of nitric oxide (NO) was similarly demonstrated.36 Using non-covalently wrapped SWCNTs has enabled specific recognition of small molecules, often without relying on biological recognition molecules such as antibodies and aptamers.30,41 (Fig. 2.b) This method was developed to detect chemotherapeutic drugs,41 riboflavin,30 fibrinogen,32 and DNA walkers.42 Several investigators have modified the interfacing environment of SWCNTs to include specific moeities to selectively target biomolecules. (Fig. 2.c) Conjugation of biorecognition elements to nanotube polymeric wrappings has demonstrated high selectivity. Antibody-modified SWCNTs have been used to develop biosensors for the detection of cardiac troponin,43 for myocardial infarction, HE4, for early detection of ovarian cancer,44 and urokinase plasminogen activator, for the detection of metastatic prostate cancer.45 Aptamer modified nanotubes have been utilized to detect bacteriophage proteins.46 Additional biofunctionalization to induce specific interactions include peptides,47,48 DNA,49 and enzymes (Fig. 2. d,e).50 A

New Technologies for Imaging and Spectroscopy Technological advancements in imaging and spectroscopy have enabled single SWCNT imaging and micro-spectroscopy. Individual SWCNTs may be spatially resolved using far-field fluorescence microscopy techniques.51 NIR and Raman (discussed in a later section) hyperspectral imaging enables acquisition of spectral data from the emission of individual nanotubes, allowing the resolution of individual species and their spectral modulation on surfaces and in cells. From spectral information data of fluorescence modulation, population parameters can be analyzed.8,52

Imaging Applications NIR fluorescence of SWCNTs has been exploited for imaging applications in living systems. Considering their uniquely photostable emission, narrow emission bandwidths, and over 20 unique photoluminescent species SWCNTS are potentially useful as imaging probes. The monitoring of SWCNTs upon uptake into live 3T3 fibroblast cells allowed their tracking during endocytosis and exocytosis events.53 SWCNT emission also was used to interrogate the permeability of 3D tumor spheroids54 and to map nanoscale organization of the extracellular space in a live mice brain.55 (Fig. 3c) The large number of nanotube species/chiralities were imaged simultaneously using near-infrared hyperspectral microscopy, demonstrating the multiplexed imaging of near-infrared emitters (up to 17 in this work) within live cells and animals.8

Intracellular Sensing NIR imaging and hyperspectral imaging of SWCNTs have opened the door for spatial imaging and measurements of emission modulation, leading to visualization of SWCNT biosensor activity within specific sub-cellular organelles.8,56 DNA-encapsulated SWCNTs are localized specifically within the lumen of the late endosomes/lysosomes, where they reversibly measured lipid accumulation in models of lysosomal storage disorders.57 Intracellular kinesin-1 motor proteins have been dynamically probed via SWCNT biosensors,58 and intracellular probing of nuclear translocation, found to be mediated specifically by importin-beta, was developed with SWCNTs encapsulated by helical polymers.59 In plant cells, the tracking of DNA release from SWCNTs has been visualized.60

In Vivo Applications In vivo studies are a major milestone for expanding SWCNT biosensors for applications as research tools, diagnostics, and therapies. The intrinsic NIR emission of SWCNTs is well suited for in vivo imaging up to centimeters within tissues. Several studies have focused on SWCNT biodistribution and found SWCNTs injected intravenously distributed in mice differently, depending on the functionalization, to the kidneys/bladder, liver, lungs, or spleen.17,61,62 Importantly, non-covalently modified SWCNTs showed no evidence of acute or chronic toxicity.63 Ovarian cancer biomarkers were detected in live mice via an antibody-conjugated SWCNT biosensor.44 (Fig. 3.a) SWCNTs have been utilized for tumor imaging by targeting cancer sites via exploiting high tumor permeability.64 Anatomical imaging with SWCNT NIR fluorescence is another avenue, in which SWCNT emission showed high penetration depth and, combined with principal component analysis, identification of organs was achieved.65 (Fig. 3.b) Vascular and 3-mm deep tissue imaging was achieved with SWCNTs66, as well as through-skull (continued on next page)

band at 1590 cm−1, G′ band at 2630 cm−1, and RBM bands in the lowfrequency region to resolve individual chiralities.

The positions of single SWCNTs were resolved in three dimensions. Fast mapping of the cell area (Fig 4.a) identified the position of a nanotube as close to the cell membrane. Figure 4.b shows the high-resolution G-band image of the individual SWCNT (identified by its RBM mode). Panels d-g in Fig. 4 show a sequence of Raman micrographs taken at varying z-location. A hotspot associated with the nanotube moves in and out of focus at different depths inside the cell.

Raman Spectroscopy and Imaging Resonance Raman scattering is one of the primary methods to characterize carbon nanotube properties. Raman scattering utilizes inelastic scattering of light to identify material ‘fingerprints’ (reviewed elsewhere).69 The power of Raman spectroscopy lies in its ability to obtain chemical information, conduct non-destructive measurements, and the lack of photobleaching phenomena. Raman spectroscopic imaging allows for spatial resolution of spectroscopic information, enabling the measurement of low material concentrations within a milieu such as a living cell or tissue.

This type of hyperspectral imaging may be conducted by several methods, including pixel-by-pixel mapping via movement of the microscope stage70 or a gimballed mirrorB, or via “global” hyperspectral imaging wherein broadband emission is passed through a turret-controlled volume Bragg grating.C Micro-Raman spectroscopy, as a tool complementary to NIR imaging, can resolve intracellular concentrations of SWCNTs on the order of nanomolar or less. Carbon nanotubes exhibit resonance Raman scattering, allowing a relatively high Raman signal as compared to other Raman active materials.

Raman scattering spectroscopy of SWCNTs is chirality/speciesspecific and can also be used to assess aggregation/bundling and defects on the nanotube sidewall.71,72, B Carbon nanotube uptake has been measured via high-speed confocal microRaman microscopy in live macrophages.74 In neural C17.2 stem cells, nanotubes were imaged at the single-particle level. (Fig. 4) Critical Raman spectral features were resolved intracellularly, including the G

Micro-Raman spectroscopy also provides chemical information from Raman active molecules in the cellular/ tissue milieu, including proteins, lipids, and nucleic acids. Signals from these cellular components, although weaker than SWCNT scattering, may be measured simultaneously, providing information from intracellular components.B

Synthesis and Nano-Characterization of Graphene Single- and Few-Layer Films

by Mark H. Rümmeli, Huy Q. Ta, and Slava V. Rotkin

T

Introduction

wo-dimensional materials (2DM)1-4 rapidly gained the attention of material scientists, physicists, and engineers due to the breadth of their electronic properties, often combined with good mechanical and thermal functionality.

Among these materials, graphene, certainly, is the best studied material with the most mature applications. Therefore, scalable synthetic technologies for growing at will various graphene materials of different properties are of paramount importance for both industry and academia.

There are a number of different approaches in which single- and bi-layer graphene can be created or isolated. At the moment, the most popular process, by far, is chemical vapor deposition (CVD). The CVD method can yield relatively high-quality graphene, and it has the potential to synthesize graphene on a large scale.5 Although the standard CVD process is straightforward for synthesizing graphene with specific desired properties, the process parameters and reactor configuration are crucial. CVD, in essence, is a process by which gaseous reactants are used to deposit material onto a substrate. In the case of graphene, the gaseous precursor undergoes pyrolysis to form carbon species. These carbon species are then carried and deposited onto the surface of the substrate and then form the carbon hexagonal lattice of graphene. To improve the pyrolysis of the precursor usually a catalyst is used to reduce the reaction temperature, but this is not a requirement. The implementation of a so-called plasma-enhanced CVD (PECVD) can help reduce pyrolysis temperatures as well. In terms of operation pressure, two broad categories exist, namely, atmospheric pressure CVD (APCVD) and low-pressure CVD (LPCVD). Different substrates can be used, however, the most successful are metals, in particular Cu as it serves as a catalyst and also, the low carbon solubility in Cu allows for easier control to form large area of homogeneous mono- or bi-layer graphene. The drawback for growing graphene on Cu is the need to transfer it off the Cu-substrate (e.g., for device fabrication) onto Si or SiO2 as this processing step can incur contamination and/or damage. Thus, a large interest exists to directly grow graphene on non-metal substrates

by CVD. The CVD technique also allows graphene doping during growth, including substitutional doping, that is, intercalation of the lattice with hetero-atoms.

CVD over Metal Substrates Solid Metal Substrates

One of most common substrates, Cu, results in homogeneous graphene growth because of its low carbon solubility along with its catalytic properties. Other metals, for example, Ni, while catalytically active, tend to have high carbon solubility. This solubility leads to inhomogeneous graphene layer formation over larger areas due to absorbed carbon precipitation during cooling. This drawback can be overcome by using binary substrates, such as a Ni film over Mo.6 Systematic studies show that during the APCVD process, the Ni and Mo break up, diffuse, and mix as independent islands.

Graphene nucleation occurs exclusively over the Ni islands, while the Mo islands around the Ni soak up excess C. In the case of Cu as a substrate, while obtaining homogenous single layer graphene is easier, growth parameters such as gas flow is crucial. Unrestricted gas flows in APCVD lead to inhomogeneity of the number of layers.

An alternative configuration in which the gas flow is partially restricted resolves this problem.7 The study showed the number of

layers to depend on the sample placement within the CVD chamber, yielding either homogeneous monolayer or bilayer graphene. Under quasi-static equilibrium gas conditions not only is the layer number stabilized, but also the quality of the graphene improves.

In another systematic study8, using Cu as the substrate in APCVD, the roles of the flow rate and relative gas ratio of CH4 to H2 were explored, and two very different growth windows are identified.

For relatively high CH4 to H2 ratios, graphene growth is relatively rapid with an initial first full layer forming in seconds. Thereafter new graphene flakes nucleate and then grow on top of the first layer (Fig.1, middle). The stacking of these flakes versus the initial graphene layer is mostly turbostratic. This growth mode can be likened to Stranski−Krastanov growth. While with relatively low CH4 to H2 ratios, the growth rates are reduced due to a lower carbon supply rate. In addition, bi-, tri-, and few-layer flakes form directly over the Cu substrate as individual islands (Fig.1, bottom). Etching studies were conducted, and they showed that in this growth mode subsequent layers form beneath the first layer presumably through carbon radical intercalation. This growth mode is similar to that found with Volmer−Weber growth and produces highly oriented ABstacked graphene. Figure 1 shows examples of the parameters space for the two growth modes.

Doping of Graphene The doping of graphene can be used to change the native materials properties, for example, to open up a band gap or overcome its surface inertness to develop catalytic activity. To open a band gap, single element doping is required, however, for enhancing the catalytic potential of graphene multi-elemental doping is needed for both heterogeneous and homogeneous catalytic applications.

Heteroatom doping can be achieved with both APCVD and LPCVD.9 Evaporating solid powder precursors upstream from the substrate yields hetero-elemental doping of graphene using LPCVD and a hydrogen-rich atmosphere. When nitrophenyl ferrocene was used as the precursor, large area graphene (formed over a Cu substrate) was successfully doped with O and N species. Selectivity between mono-, bi-, and a few-layer graphene could be obtained by adjusting the reactor configuration, temperature, and growth time.9 Using a similar setup, but with the reaction optimized for 1,2,5,6,9,10-hexabromocyclododecane, doped mono- and fewlayer graphene with covalent C-Br and O-doping was successfully demonstrated.10

Liquid Metal Substrates

One of the disadvantages of metal substrates for large area CVD growth of graphene is the presence of microstructure defects such as grain boundaries. Due to difference in C solubility near the substrate defects during the growth process, it is hard to achieve a uniform large area graphene films due to excess C precipitation in the course of cooling down. In addition, substrate crystal orientation can affect graphene growth kinetics. In the case of a liquid metal substrate, these aspects can be eliminated. In an early demonstration liquid p-block elements (e.g. Ga) were used for the synthesis of monolayer graphene in APCVD.11 The electron mobility of single crystal domains grown on liquid Ga surfaces was as high as 7400 cm2V-1s-1 under ambient conditions, indicating high-quality single crystal graphene flakes. The technique is relatively simple and does not require film deposition or vacuum systems. A later systematic study with liquid metals

showed they are highly suited for single layer graphene growth.12 During cooling the surface metal solidifies quickly, thus blocking the precipitation of absorbed carbon. As a result, such a growth is a self-limited catalytic process and robust to variations in growth parameters.

CVD over Non-Metal Substrates An early work showed the potential of oxides as non-metal substrates for growing graphene.13 One of the more important substrates is Si wafers (Si/SiOx). Although various studies have been conducted to achieve graphene synthesis directly on the SiOx surface, it was proven that obtaining large-area, homogeneous monolayer graphene is challenging. To overcome this limitation, a confinement technique was proposed in which two Si/SiOx wafers are placed with their oxide faces in contact in a sandwich configuration, which can yield homogeneous single-layer large area graphene.14 The graphene is polycrystalline and the grain boundaries are facetted (Fig. 2) indicating further improvements are needed.

Graphene also can be directly grown on Al2O3 wafers, although this typically requires very high temperatures for good quality (poly-crystalline) graphene.15 The potential for graphene CVD growth at low temperatures, 325oC, on an oxide was demonstrated using MgO crystals with acetylene as the precursor.16 Such lowtemperature growth is relevant for BEOL (back-end-of-line) integrated circuit fabrication, to maintain the mechanical integrity of intermetal dielectrics in Sitechnology.

In addition, graphene can be grown on a number of traditional glasses which may find applications in technologies beyond transistors. The direct, well-controlled growth of high-quality graphene on insulating solid glasses was demonstrated

by APCVD, where the layer thickness was also tunable.17

Molten Non-Metal Substrates

It is believed that in using a molten insulator substrate, uniform nucleation and accelerated growth of graphene can occur. This process was demonstrated by APCVD on soda- lime glass, which has a low softening point of 620oC. Sodalime glass is inexpensive and already used in various applications.18 Asproduced graphene on soda-lime glass was used for smart heating-devices, with potential applications for transparent defoggers, thermo-chromic displays, and biocompatible cell culture medium.

Characterization of Multi-Layer Graphene The capability to synthesize a breadth of 2DMs, including their advanced heterostructures with complex morphology and electronic properties dependent on the structure, requires appropriate instrumentation to probe such materials properties. Here, we focus on a single technique—confocal Raman microscopy19,20—which has been proven to allow non-destructive materials characterization, while a number of other methods exist that deserve their own review.

Raman scattering has been extensively used for characterization of graphene,21,22 as well as other 2D materials.23-25 This use is due to (1) the existence of specific Raman lines for these materials, corresponding to optical phonons and their combinations, (2) the high brightness of these Raman features if excited in resonance with electronic transitions in 2D materials, and (3) most importantly, the strong coupling of these phonon modes to the lattice structure, including strain, defects and layering, the electronic structure, including doping level, and other physical parameters of interest, such as the rotational registry in twisted materials. Figure 3 c, d shows typical Raman spectra of monolayer graphene samples on the different substrates (blue: isolated by hexagonal BN (hBN) films on both sides; red: just coated with hBN on SiO2 substrate).

In confocal Raman microscopy, the excitation laser light is tightly focused to a diffraction-limited spot as shown in panel (a), and thus, the Raman scattered signal is collected from a small volume in the focal spot. As a result, a (singlepoint Raman) measurement provides local information from the specimen.

Scanning the sample while collecting the Raman data allows one to map the materials properties point by point.

Inspection of the graphene sample begins with identifying two major characteristic Raman peaks, denoted as G and 2D, at ~1600 and 2700 cm- 1. Fitting the shape of the Raman peaks with a Lorentzian (for uniform broadening) or Gaussian (for non-uniform broadening) yields, for each line, three main parameters: the peak’s position (frequency), width (broadening), and intensity (oscillator strength). Each of these parameters is specific for the material under investigation: for example, in panel (e) the map of the hBN-peak intensity shows clearly the area with 0-, 1-, and 2-hBN layers. Similar maps (shown in Fig. 4 a,b) of the width of G or 2D-lines also have different contrast in regions I and II. This difference in linewidth is (continued on next page)

In conclusion, two of the most important techniques to, first, fabricate graphene through CVD, and second, characterize graphene through confocal Raman spectroscopy, have been presented. The tremendous success of these techniques lies in their versatility, ease of use, and accessibility. CVD provides tremendous options for graphene growth over multiple substrates under numerous conditions and can also deliver control in terms of layer number as well as layer stacking configuration.

This opens the technique as ultimately being viable for numerous applications.

After having synthesized graphene, it is critical to rapidly and easily evaluate the material, and confocal Raman spectroscopy offers this by enabling this Fig. 5. Raman mapping of twist in graphene bi- and tri-layers. (c) Schematic representation and (d) optical single technique to evaluate numerous image of the sample: central part of the island has three layers (dark color) with different twist of the bottom properties such as lattice structure, monolayer with respect to AB-stacked second and third layers, ±10o; the area around it (light color) is a twisted bilayer, ±10o; the rest of the surface is covered with a monolayer (green).

(Rotkin, unpublished.) interest, such as the rotational registry in twisted materials.

2019 Edward G. Weston Summer Research Fellowship – Summary Report Development of an Integrated Characterization Tool for Flow-Electrode Electrochemical Water Treatment Technologies

by Bilen Akuzum

T

he projected decline in fresh water reservoirs over the next century attracted researchers towards the development of novel technologies that can offer low-cost and robust treatment of brackish and saline waters1. Among many proposed technologies, flow-electrode capacitive deionization (F-CDI) is a promising capacitive desalination technology that can mitigate the majority of the shortcomings associated with conventional CDI systems and offer continuous and scalable treatment of brackish and saline water resources 2.

F-CDI utilizes aqueous suspensions (i.e., slurries) of high surface area capacitive materials to capture charged ions under the application of a small electrical potential (~1.2V). As seen in Fig.1, during salt capture, the slurries are pumped through a polarization cell that contains three parallel flow channels

separated by two ion-exchange membranes.

Under the application of an electrical potential, the suspended capacitive particles accept their charge through a percolating network of conducting particles and adsorb salt ions from the center water channel. In this process, the flowable aspect of the slurry electrodes allows facile transport of saturated particles out from the reactor, while continuously introducing fresh capacitive particles into the ionexchange front. Unlike conventional solidelectrode systems, this allows continuous operation and steady state salt removal rate in the capacitive water treatment module.

In addition, the ion-saturated electrodes can be transported to a reverse-polarized regeneration reactor to continuously desorb the salt ions into a separate effluent stream and recover a portion of the energy that was initially supplied for salt capture3.

Significant efforts have been put in recent years to the development of various types of capacitive materials for flow-electrode based water desalination4. Along with materials research, studies regarding flow design5 and modeling6 have also been reported. As F-CDI systems continue to demonstrate their potential for brackish water deionization, the necessity for studies regarding systemlevel performance metrics such as long-term cycling, resistance to flow (i.e., pressure drop), total energy consumption, and round-trip efficiency also becomes critical. Motivated by this, the objective of this work was to develop and manufacture an integrated experimental characterization tool that can work in parallel with a potentiostat to allow researchers to conduct system-level diagnostics and establish a better understanding of commercial feasibility in flow-electrode based water treatment technologies.

As seen in Fig. 2a and 2b, an automated sensor-based experimental testing station was designed and manufactured using commercially available parts and materials, which can be controlled through a touchscreen computer running on LabView.

The finalized unit is capable of running diagnostics on two separate flow-electrode polarization cells both in series and parallel flow configurations to offer flexibility in stack design. Ionic conductivity and pH sensors were placed near the inlets and outlets of the flow cells to capture time-dependent salinity and pH changes in the influent and effluent streams. In addition, digital pressure sensors were integrated in close proximity to both slurry and water inlets and outlets to track the pressure gradients across flow-cells with different flow configurations and stack modules. Moreover, peristaltic pumps with

adjustable flow rate and operating modes (i.e., continuous vs. intermittent flow) were accommodated to achieve full control over the operating conditions of the experiments.

Electrical current and voltage monitors were also integrated to the microcontroller circuitry to track the power consumption of the pumps and the polarized flow cells, which are parameters that are widely overlooked in majority of the existing studies. A picture of the assembled Arduino tentacle shield with pump connections, as well as pressure, current, and voltage monitors can be seen in Fig. 2c.

As F-CDI continues to climb up the ladders of the technology readiness levels, relying on potentiostats and environmental sensors (i.e., conductivity and pH probes) as the only assessment tools becomes less adequate to holistically capture the performance metrics. Understanding the scalability and system efficiency aspects of a novel electrochemical water treatment technology is crucial in providing guidance to engineers and investors in technology transfer scenarios. In this manner, metrics such as long-term cycling, resistance to flow (i.e., pressure drop), total energy consumption, and round-trip efficiency should be investigated using integrated experimental setups similar to the one described in this study. In fact, the integrated testing station measures and combines the power consumption of the pumps with the power input of the potentiostat, which generates a crucial metric in providing a more realistic understanding of the efficiency of the proposed ion-exchange process. In addition, the modularity of the testing station allows long-term cycling experiments to be conducted in series or in parallel between two or more flow cells, offering more degrees of freedom in stack design.

Availability of such system-level data at the early phases of a technology development generates a quicker feedback loop, aiding scientists in quickly adjusting their research efforts in accordance with the industry needs.

For instance, by utilizing the finalized version of the testing station, two research groups are currently collaborating in developing an ion selective, low-cost flow-electrode water treatment system, with the final goal of establishing a patentable technology that is attractive to the industry. In this manner, keeping track of all the metrics that are relevant to the real-world applications allowed us to understand industry-relevant target performances better and adjust our research accordingly. Ultimately, the established characterization apparatus gives researchers the necessary tools to better understand their technology, while allowing an improved level of compliance with the industry standards, which can help accelerate commercialization efforts.

The 2019 F.M. Beckett Summer Research Fellowship – Summary Report Metaphosphate Class of Redox-Active Materials for Oxygen Evolution Reaction

by Ritambhara Gond

T

he energy storage sector facilitates research on the development of novel electrodes for metal-ion batteries, and economic catalysts for metalair batteries, fuel cells and water-splitting devices. In Li-ion batteries (LIB), after the great success of LiFePO4 as a cathode, phosphate-based materials have been extensively studied.1 LIB empower suites of portable electronics and (hybrid) electric vehicles, while for large-scale micro-tomega stationary grid storage purposes a more economical option such as sodium-ion batteries (SIB) has been developed. In this quest, the viability of metaphosphate as a cathode for SIB has been recently explored where NaTM(PO3)3 [TM = Fe, Co] showed reversible Na+ (de)intercalation.2,3 In parallel, there has been a great interest in exploring Li-based cathodes (LiFePO4 and LiCoO2) for the oxygen evolution reaction (OER).4 Herein, we have studied NaTM(PO3)3 [TM = Co, Ni] metaphosphate class of materials for OER in alkaline pH. The reversible M3+/M2+ redox reaction in metaphosphates leads to the possibility for that these battery insertion materials could split water and evolve oxygen under an applied potential.5 A simple solution combustion and solid-state method was

used to synthesize NaCo(PO3)3 followed by annealing in air (NCoM-Cb-Air and NCoMSS-Air) as well as in argon (NCoM-Cb-Ar and NCoM-SS-Ar) atmosphere resulting into four Co-containing catalysts. This study was further extended to NaNi(PO3)3 prepared by a solid-state method. Powder X-ray diffraction patterns (XRD) of solidstate prepared NaCo(PO3)3 and NaNi(PO3)3 are shown in Fig. 1a and b respectively, with their respective SEM micrographs as insets. Cubic NaCo(PO3)3 exhibits excellent OER activity with huge current density (Fig. 2a). The mass activity of combustionsynthesized metaphosphate catalyst annealed in argon atmosphere (NCoM-CbAr) was found to be 536.5 A g-1, which is higher than state-of-the-art RuO2 (332 A g-1). The overpotentials of all four Co-based catalysts were compared with NCoM-Cb-Ar showing the lowest overpotential of 340 mV, similar to that observed for RuO2 (340 mV).

These were measured at 10 mA cm-2 current density during OER. The NaCo(PO3)3 catalyst showed the lowest overpotential with the least loading compared to other PO4based catalysts, as reported in the literature (NaCoPO4 and Na2CoP2O7) without addition of any amorphous carbon during the slurry preparation.6 This study was further extended to NaNi(PO3)3, where the material

was tested in Ar-saturated 0.1 M KOH (Fig. 2b). The material could reach 10 mA cm-2 at an overpotential of 370 mV, whereas RuO2 could not even reach 10 mA cm-2 of current density in 0.1 M KOH electrolyte.

The remarkable inherent OER activity in NaCo(PO3)3 and NaNi(PO3)3 arises due to the corner-shared TM-O6 and pyrophosphate (P2O7)4- units (inset of Fig. 2a and b) which are isolated, i.e. not edge shared, causing a stable crystal chemistry during OER reaction. Also, the presence of P makes TM more electrophilic acting as a good catalytic center for OH- adsorption.

In conclusion, NaTM(PO3)3 [TM = Co, Ni] metaphosphates are shown to be an efficient and economic class of catalyst for oxygen evolution reaction. These redox-active materials showed superior OER activity than RuO2 in alkaline solution. In particular, NaCo(PO3)3 showed a surprisingly high catalytic activity of OER in 1 M KOH with an overpotential of 340 mV at a current density of 10 mA cm-2. Similarly, in the case of Ni-analogue of metaphosphate the overpotential was found to be 370 mV at a current density of 10 mA cm-2 in 0.1 M KOH electrolyte. © The Electrochemical Society.

ST UDENT NE WS Imperial College London Student Chapter The ECS Imperial College London Student Chapter has organized a series of member events since its founding in October 2018. These include the inaugural seminar by David Williams, University of Auckland; and corrosion research seminars by Sukanta Ghosh and Tom Bos, Shell Technology Centre Bangalore, and Oumaima Gharbi, Paris-Sorbonne University.

The highlight of the year was co-organizing the SE-lectrochem 2019 meeting. Some 120 early career researchers in electrochemistry from Southeast England and beyond came together on September 19, 2019 to share ideas, present work, and form new collaborations.

Keynote speeches were delivered by leading academics and industry representatives including Paul Shearing, Mary Ryan, Andrea E. Russell, Anthony Kucernak, and Chris Zalitis. Early career researchers gave “quick-fire” two-minute pitch oral overviews of their posters.

The audience approached the speakers with more questions and discussion during the poster sessions. Best oral presentation prizes were chosen by audience vote. The panel of judges decided the best poster prizes.

SE-lectrochem 2019 was generously supported by The Electrochemical Society; Royal Society of Chemistry; The Faraday Institution; Energy Futures Lab at the Imperial College London; Metrohm AG; and Alvatek Electronics. The Imperial College London Student Chapter’s conference committee included Nina Meddings, Aigerim Omirkhan, Colleen Jackson, Rowena Brugge, Barun Chakrabarti, Edouard Querel, Mei-Chin Pang, Daisy Thornton, Rose Oates, and Ozden Celikbilek. The chapter received a lot of positive feedback and expects to hold the event annually at different institutions across Southeast England.

The second highlight of the year was the COMSOL Multiphysics® workshop on modeling electrochemistry organized by Epameinondas Skontzos and led by Panagiota Theodoulou and Ross Hubble. After the software was introduced and demonstrated, participants had the opportunity to test applications and discuss research problems with COMSOL experts.

ST UDENT NE WS Montréal Student Chapter The ECS Montréal Student Chapter organized its ninth annual symposium on May 10, 2019. Over 100 people registered for the symposium at the Université du Québec à Montréal (UQAM) Sherbrooke building. This was one of the largest symposia in the chapter’s history. Although chapter membership more than doubled from 11 in 2018 to 24 in 2019, it remains small, while the symposia consistently draw large audiences. Participants came from New York State to participate in the symposia, and this year, the chapter included student members from the United States.

Nikolay Kornienko, Université de Montréal, delivered a keynote address on his PhD research on hydrogen evolution and CO2 reduction catalysis. Gerald Frankel, Ohio State University, gave a second passionate keynote address about the corrosion of nuclear waste storage systems, and how his group is developing new materials that can stand the test of time.

The symposium included six student oral presentations and 11 student poster presentations. Poster presenters delivered a threeminute oral presentation before the poster session. This new feature, which allowed attendees to direct themselves to the most pertinent poster, was popular and will likely be repeated in the future.

The event was very positively received. Twelve industrial and academic sponsors offered their support. Of these, three sponsors had booths at the event and sent representatives to answer questions: Annick Lavallée, Metrohm; David Polcari, Systems for Research; and Michel Dumont, Snowhouse Solutions. There were two sponsored talks, the first by Laila Benameur, Quebec Scientific Entrepreneurship (QcSE), who described their program allowing students to receive funding for novel ideas they would like to test independently. David Polcari from Systems for Research spoke as well, and graciously donated two android tablets to the first place winners of the poster and oral presentations.

The ECS Montréal Student Chapter’s November workshop is on basic circuits and their ubiquitous use in electrochemistry.

University of Pennsylvania Student Chapter One week after its official founding, the ECS University of Pennsylvania (U Penn) Student Chapter participated in NanoDay@ Penn. Held on October 22 at the Singh Center for Nanotechnology in Philadelphia, the goal was to demonstrate frontier research fields to local high school students.

In total, 156 students from eight high schools attended. Jintao Fu and Sam Welborn, PhD students in the U Penn Materials Science and Engineering Department—and founding members of the new U Penn Student Chapter—presented electrochemistry demonstrations under the guidance of Chapter Advisor Dr. Eric Detsi. Two electrochemical processes were demonstrated: oxygen evolution on Ni foam during electrolysis of water, and electrooxidation of Ag from an Au-Ag alloy.

The students were excited to see bubbles forming on the Ni electrode during oxygen evolution. They watched intently as the color of AuAg alloy changed from silvery to golden brown upon application of current/potential. Students learned how the electrochemical concepts behind these demos could be applied to the processing of novel materials for catalysis, energy storage and conversion, and more.

NanoDay@Penn was a successful start for the new chapter. Moving forward, the chapter’s short-term goal is to recruit new members, and search for partner organizations on campus including the Vagelos Institute for Energy Science and Technology and the Kleinman Center for Energy Policy. The chapter also plans to reach out to off-campus organizations, such as our neighboring ECS Drexel University Student Chapter, to plan and hold Philadelphia-wide events.
