An experiment in Professor Vivian Ferry’s lab reveals nanocrystals that emit different colors in response to UV light. Sustainability is a growing focus in nano optics, the study of how light interacts with nanometer-scale objects. Ferry is looking for nontoxic ways to make materials that capture solar energy.

LARGEST CLASS IN HISTORY This fall, our college welcomed the largest incoming class in history, as we head for undergraduate growth of 20 percent by 2028. The enrollment of 1,569 freshmen represents an almost 9 percent increase from last year—and includes jumps in underrepresented students and our international population. Overall, undergraduate enrollment now tops 5,800 students, also a record number.

DEAN ANDREW ALLEYNE Smart investments that sustain A hallmark of our community lies in our relentless pursuit of game-changing research. Our faculty, students, and alumni are key players in important areas that affect people, our planet, and the economy. This edition of Inventing Tomorrow is dedicated to sustainability, specifically as it pertains to water, materials, transportation, and energy. As custodians of the future, we recognize the profound impact of our actions on the environment, and we are committed to finding responsible solutions. I call our approach “smart sustainability.” We harness the power of artificial intelligence (AI) and data modeling to propel work forward—plus we tackle problems with circularity, or full life cycle, in mind. For example, in the AI-CLIMATE Institute, CSE researchers are leveraging AI for climate-smart practices in agriculture and forestry industries (page 5). In the NSF Center for Sustainable Polymers (CSP), experts are transforming how plastics are made, unmade and remade (page 21)—with the idea of closing the loop with biodegradable plastics. Circularity in sustainability isn’t just a concept for us. It’s a practice. We do our best to think about what happens after we innovate, build, shape, solve. In fact, we are growing a community of leaders with resource conservation and upcycling skills. This fall, as part of a $3 million National Science Foundation grant, we’re offering students a course on this topic, “A Circularity Revolution: Working to Close the Loop on Global Issues.” By integrating innovation with responsibility, we can make sustainability not just an aspiration but a way of life.

AMONG THE MOST CITED RESEARCHERS IN THE WORLD It’s no small feat to author so many important scientific papers that you land in the top 1 percent of citations in your field. Four CSE faculty members—R. Lawrence Edwards, Dan Knights, Tony Low, and Donald Truhlar— did just that. They were named among the most “Highly Cited Researchers” worldwide by Clarivate Analytics, showing that they have a broad and significant influence in their field.

NEW $20M INSTITUTE WILL USE AI TO MITIGATE CLIMATE EFFECTS Tackling Earth’s hefty carbon emissions is a mighty task, which is why University of Minnesota researchers are leveraging farms and forests—and AI—to do it. The University recently received a $20 million grant over five years from the National Science Foundation (NSF) and the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) to lead a new National Artificial Intelligence Research Institute. Dubbed the AI Institute for Climate-Land Interactions, Mitigation, Adaptation, Tradeoffs and Economy (AI-CLIMATE), the research center will use artificial intelligence FA L L 202 3

techniques to create more climate-smart practices that will absorb and store carbon while simultaneously boosting the economy in the agriculture and forestry industries. For example, farms and forests can be used as carbon sinks, which pull more carbon dioxide out of the atmosphere than they release. Using new AI techniques like deep learning and knowledge-guided machine learning, researchers at AI-CLIMATE can improve accuracy and lower the cost of accounting for carbon and greenhouse gases in these sinks, ultimately making the process more accessible for more people.

FIRST-OF-ITS-KIND KIDNEY CRYOPRESERVATION HAS LIFE-SAVING POTENTIAL Did you know that 20 percent of kidneys donated for transplantation each year can’t be used? Often, the organs don’t reach the recipients in time and can’t be put on ice for longer than a few hours. This year, University of Minnesota scientists and engineers made a breakthrough in the field of kidney cryopreservation—or preserving the organs at ultra-low temperatures—by successfully transplanting a rewarmed, functional kidney into a rat for the first time. Their research has the potential to save thousands of human lives by enabling long-term storage of organs.

CSE FACULTY RECEIVE TOP NATIONAL AWARDS From National Academy inductions to Nobel Prize equivalents, our CSE faculty received some of the highest honors in the science and engineering fields this year. Among them are CSE Dean Andrew Alleyne (elected to the National Academy of Engineering), physics and astronomy Professor Boris Shklovskii (elected to the National Academy of Sciences), earth sciences Professor Emeritus David Kohlstedt (received the Vetlesen Prize, the Nobel Prize equivalent in the earth sciences field), biomedical engineering Assistant Professor Brittany Hartwell (awarded the international Michelson Prize for excellence in vaccine research), and mathematics Professor Svitlana Mayboroda (received a 2023 Blavatnik National Award honoring America’s most innovative scientists and engineers).

SUSTAINABLE MAGNET STARTUP GETS $17.5M FROM DOE Back in 2014, CSE electrical engineering Professor Jian-Ping Wang developed the technology behind the Clean Earth Magnet, the world’s first high-powered, rare-earth-free permanent magnet. One of the “key building blocks for a sustainable society,” these magnets provide less expensive, more environmentally friendly components for electric vehicles, wind turbines, and other renewable energy technologies. Last fall, Niron Magnetics, a startup company spun out of Wang’s research, received $17.5 million from the U.S. Department of Energy (DOE) to scale up its magnet manufacturing, paving the way for the U.S. to achieve its goal of net-zero emissions by 2050.

At least 25 million Americans suffer from tinnitus, or “ringing in the ears,” and treatments have long eluded medical researchers. But now a new, non-invasive device may hold the key to treating the pervasive condition— and it just received U.S. Food and Drug Administration (FDA) approval for use in the United States. Biomedical engineering Professor Hubert Lim is part of the international team that developed Lenire®, a device that combines sound therapy and electrical tongue stimulation to curb tinnitus symptoms. In a recent clinical trial, nearly 80 percent of patients’ symptoms significantly improved after a 12-week course of treatment with the device. The device is now available for audiologists and ear, nose, and throat (ENT) doctors to prescribe to their patients.

FACING NEURODEGENERATIVE DISEASES HEAD ON Alzheimer’s, Parkinson’s, mad cow disease, and chronic wasting disease (CWD) all share a common feature—the buildup of misfolded proteins in the central nervous system. Detecting these molecules is crucial for understanding and diagnosing these devastating disorders. University of Minnesota researchers, including electrical and computer engineering Professor Sang-Hyun Oh, recently developed a new diagnostic technique to make the process faster and easier. Their “NanoQuIC” technology cuts detection times from about 14 hours to four and increases the sensitivity by a factor of 10, opening a door for earlier treatment and mitigation of various neurodegenerative diseases that affect both humans and animals.

TINY GALAXY WITH BIG STAR POWER Even the tiniest of stars can have the biggest impact. Or at least that’s what CSE astrophysics researchers found when they looked more than 13 billion years into the past to discover a minuscule galaxy that generated new stars at an extremely high rate for its size. Spotted using observations from the newly minted James Webb Space Telescope, the galaxy is one of the smallest ever discovered at this distance— around 500 million years after the Big Bang. Studying its unique properties could help astronomers learn more about galaxies that were present shortly after the Universe came into existence.

REVEALING THE POLAR REGIONS IN STUNNING DETAIL You can now take a virtual, high-definition hike through the Earth’s polar regions, thanks to researchers at the University’s Polar Geospatial Center (PGC). Their recently created maps and videos use high-resolution data from polar-orbiting satellites about 400-700 kilometers above Earth. In addition to being the most detailed polar maps ever created, the images can provide environmental researchers with new insights into the effects of climate change over time.

GROWING THE NATION’S SEMICONDUCTOR WORKFORCE The global semiconductor market is expected to become a trillion-dollar industry by 2030—but with increasing demand for jobs comes the need for those who can do them. CSE’s Technological Leadership Institute (TLI) recently announced the launch of the Minnesota Semiconductor Manufacturing Consortium, a groundbreaking initiative aimed at upskilling Minnesota’s technical workforce for careers in semiconductor manufacturing. The consortium is supported by industry leaders Honeywell, Collins Aerospace, and Polar Semiconductor; the University’s own Minnesota Nano Center; and the Minnesota Department of Employment and Economic Development (DEED).

Sustainability research in CSE is wide-ranging, far-reaching “If you take care of nature, nature will take care of you.” Wise words from Sir David Attenborough, the 97-year-old longtime host of BBC’s “Planet Earth.” He has also said the living world will endure, with or without us: “This is not about saving our planet, it’s about saving ourselves.” To that end, this section—these two pages and the next 18—highlight some of the work and people making an impact in the world of water, materials, transportation, and energy. Why these four areas? Because it is next to impossible to capture all that falls under the realm of environmental sustainability at the University of Minnesota College of Science and Engineering (CSE) in one magazine. There are too many areas of research—from detecting bird and bat collisions at wind turbines to chemically transforming

“I’ve stayed here for 40 years for a reason,” said Kim Stelson, mechanical engineering professor and founding director of the U’s Center for Compact and Efficient Fluid Power. “It is because of the fact that there are so many of my colleagues, both scientists and engineers, in other departments that I can work with. We really do have a complete portfolio of these different skills, expertise, and technologies that can hasten a research or offer different perspectives to look at a problem.”

So it’s no surprise t hat C SE scientists and engineers across the globe are spurring innovations in environmental sustainability.

Testing the waters BY OLIVIA HULTGREN

Of all the things that make the University of Minnesota unique, being perched on the bank of the mighty Mississippi River—right next to a major city—might take the cake. And water isn’t just in our line of sight. It’s a vast area of study in the College of Science and Engineering. From studying geological change in the Lake Superior basin to working with local breweries to reduce their wastewater output using carbon-eating bacteria, our researchers are making waves that will benefit both the state of Minnesota and beyond. ››

WAKE SURF WAVES As part of St. Anthony Falls Laboratory’s (SAFL) Healthy Waters Initiative, CSE researchers are studying how waves from boats used for the popular sport wake surfing affect shorelines in Minnesota lakes. By measuring wave height and power from these boats, the researchers found that wakesurf boats produce higher waves than typical boats and are more likely to cause lakeshore erosion.

COMMITTED TO CLEAN—

RESEARCHERS TAP FUNGI AND PARTNER WITH TWO CITY UTILITIES FOR BETTER WATER QUALITY Of all the harmful effects of climate change on our planet, water quality is one of the most pertinent. Extreme rainfall can lead to stormwater management issues and increased pollution from nitrogen runoff, and rising temperatures cause toxic algae to bloom in our lakes. To address these water quality issues and more, a swath of CSE researchers are turning to chlorine, trees, and… fungi? Yes, fungi. According to CSE Associate Professor Peter Kang, the spore-producing organisms can actually lend a hand in purifying contaminated water systems. “One of the major challenges that groundwater scientists face is remediating contaminants that

slowly diffuse into rock and trap there for long periods of time,” he said. “And it’s really hard to extract them. So, our idea was utilizing branching fungi to actively grow and penetrate into this porous rock to access the contaminants.” Kang’s project is funded through Minnesota’s Discovery, Research, a nd I n noVat ion E c onomy (MnDR I V E) progra m, a University partnership with the state. His lab is also working on a variety of groundwater-related problems, including another MnDRIVE-funded endeavor to mitigate the clogging of biofilms in an underground aquifer on the University’s West Bank. The work was recently published in the Proceedings of the National Academy of Sciences.

“A better understanding of fluid flow and subsurface systems is key to addressing global climate, water, and energy issues,” Kang said. “Nearly 99 percent of unfrozen freshwater is stored in the form of groundwater, and Minnesota, for example, relies a lot on groundwater systems, so it’s important for both our state and beyond.” Minnesota actually provides a unique platform for studying water quality, thanks to the proximity of its two major cities—Minneapolis and St. Paul. Civil engineering Professors Ray Hozalski and Tim LaPara have been working closely with the two cities’ water utilities departments for years now to study water quality and implement solutions for cleaner

SNAPSHOTS IN THE ICE When earth scientists study ice, they’re not just monitoring ice melt spurred by the planet’s inevitable warming. Frozen water, whether it’s part of glaciers in the mountains or ice sheets in Antarctica, contains an entire world of information that can give us a detailed history of how the Earth has changed over

Some of their larger projects involve finding ways to prevent harmful bacteria (such as Legionella, the waterborne culprit behind a severe form of pneumonia) from building up in the water supply.

Environmental Protection Agency (EPA) to study the occurrence of opportunistic pathogens throughout the country’s water distribution systems and find out how cities can balance levels of chlorine in water to combat

“Minnesota is a great place to do what Tim and I do,” Hozalski said. “It’s particularly exciting to work with Minneapolis and St. Paul water utilities because we can do fundamental academic work that gets published in top journals, and we’re also solving real world problems at the same time. This, along with the resources, facilities, and our talented students at the University, have enabled us to be really, really successful.”

Talghader isn’t the only one at the University of Minnesota tapping into the power of ice. Sara Nadian, a junior studying earth science on the Twin Cities campus, spent a semester analyzing old ice cores from Greenland through Research Assistant Professor Joel Barker’s Polar Biogeochemistry Lab. Her project studied the detrimental effect meltwater can have on our ability to date ice by analyzing the chemical remnants in the ice. “I had no idea how much information you could get from just two meters of ice,” Nadian said. “It was really cool for me to take what I learned in class and apply it to research. We have really amazing professors in the earth science department who have literally invented the things that a lot of geologists around the world use to date rocks and ice, so there are a lot of opportunities to get involved here.”

MATERIALS

Material world BY OLIVIA HULTGREN

Materials are everywhere. Objects we use every day—your cell phone, the sweat-wicking long sleeve you wore to the gym yesterday, that coffee mug you’re probably drinking out of right now—they’re all made up of substances that have been carefully analyzed and designed to function optimally for their respective purposes. And just as the word itself suggests, materials research permeates nearly every department in the College of Science and Engineering.

Our researchers are working every day to engineer more efficient materials with better functionality and lower environmental impacts—from invisible solar panels to plant-based cleaning products. Curious? See for yourself. ››

EVERYTHING UNDER THE SUN Imagine working in an office building with floor-toceiling windows. You may not even notice, but the windows separating you from the outside world are also powering the electricity inside the building—through invisible solar cells in the glass. Although still in development, this is the sort of technology that chemical engineering and materials science Associate Professor Vivian Ferry’s research makes possible. Her lab specializes in solar energy and optical materials, or substances scientists can leverage to harness the power of light. “We create materials that interact with light—manipulate it, guide it, change reflection, change absorption, etc.,” Ferry explained. “Our goal is to modify all these optical properties and then integrate them into a number of different advanced application spaces, like photovoltaics, clean energy development, and finding ways to increase the efficiency of our solar panels through optical design.” A big part of Ferry’s research is hands-on—physically fabricating materials and devices in the lab and adding tiny patterns on their surfaces in order to alter their properties for the better. The other half of her research is computational.

Ferry and her students use computer modeling and realworld weather data to test how well their innovations would work, say, integrated into solar panels in an agricultural field. Her group is working with mechanical engineering Professor Uwe Kortshagen to plan how they can install their technology in greenhouses and farms to create more seamless energy-saving, sun-powered systems. It’s that collaborative spirit present in both the College and the Department of Chemical Engineering and Materials Science that initially drew Ferry to the University of Minnesota. That, coupled with the one-ofa-kind facilities and resources on the Twin Cities campus like the Characterization Facility and the Minnesota Nano Center, both of which Ferry and her researchers frequently use. “I think the fact that we are chemical engineering alongside materials science is really beneficial because you get that perspective from lots of disciplines to tackle problems that are inherently interdisciplinary,” Ferry said. “Materials span lots of other disciplines in lots of ways. I love that being a ‘college of science and engineering’ is useful for being able to make those kinds of connections.”

RESEARCH TO INDUSTRY:

REWRITING THE CHEMISTRY PLAYBOOK In the process of biomass pyrolysis, thousands of chemical reactions happen in the span of a few seconds. Bio-based ingredients like plants, grass, and corn are heated to extremely high temperatures until they melt into a substance that resembles crude oil. It’s an exercise in chemical experimentation that scientists never truly understood—until 2014 when UMN chemical engineering Professor Paul Dauenhauer and his then Ph.D. student, Christoph Krumm, found a way to study it. They developed a reactor system that essentially allowed them to spread chemical reactions out over long periods of time so that they could analyze what was really happening. That innovation eventually allowed the researchers to discover new ways to create useful biofuels and chemicals from plants. In 2016, they commercialized their findings and formed Sironix Renewables, a startup with a mission to replace petroleum-based materials in cleaning products with eco-friendly, plant-derived ingredients that actually work better than their fossil fuel counterparts.

Dauenhauer’s lab is well-known for being a treasure trove of sustainable technology. In addition to Sironix, his research has spun into two other startups in the last decade. One of those is Carba, a carbon dioxide removal company that won the 2023 Minnesota Cup Grand Prize of $85,000. The other is Låkril Technologies, which specializes in converting lactic acid from corn into acrylic acid for use in products such as diapers and paint. The startup plans to open a pilot plant by the end of next year. Låkril leverages a catalysis process drummed up by Dauenhauer’s former chemical engineering Ph.D. student Yutong Pang, who now works as a senior research specialist at Dow Chemical Company in Houston, Texas. Pang said one of the most important things she learned from her former mentor is to approach all projects with a mindset for sustainability. “Paul’s innovative mindset really triggered us to always think about new ideas,” Pang said. “In his lab we did biomass conversion, plastic recycling, plastic pyrolysis—these are all hot topics in the industry right now, and we got to grow in that academic Photo credit: Sironix Renewables

“Green and bio-renewable products are becoming increasingly important, and companies are making strong commitments to it,” said Krumm, who’s now the CEO of Sironix, based in Seattle, Wash. “But it’s still a big barrier for businesses to switch

from petroleum. Over the next five years, we plan to rapidly scale the process where we can produce large quantities of the product and actually sell it to customers.”

environment. Since sustainability is also a big component at Dow, being exposed to different ways that you can practice sustainable chemistry was very important for me.”

“Paul is someone who approaches a problem barely within the constraints of what our physical world is capable of,” Krumm said. “He’ll push research to the very edge of the laws of thermodynamics and come up with really unique ideas. Not all of them work, but the one thing that does has a massive impact. That’s something I’ve really taken to heart. There aren’t enough crazy ideas being tried. If no one’s tried it, then why not?”

In 2020, Dauenhauer received the prestigious MacArthur Fellowship, widely referred to as the “genius grant,” honoring his contributions to renewable materials research and the green technology industry.

THE CENTER FOR SUSTAINABLE POLYMERS The University’s NSF-funded Center for Sustainable Polymers (CSP), directed by Professor Marc Hillmyer, plays a critical role in generating environmentally friendly solutions for the plastic industry and fostering collaboration both within and outside of UMN.

What is a polymer?

Polymers are chemical compounds made up of long chain molecules containing repeated units. They are found in everything from proteins in our body to the plastics and rubber materials we use every day. FA L L 202 3

Since its inception in 2009, CSP has grown to be one of the most prolific research centers in the sustainable polymers realm:

CSP origin startup Valerian Materials, which makes sugar-derived monomers and polymers for sustainable products, received a $1.1 million BioMADE grant last year to fund further development. Another company, BKB Floral Foam, Inc.—co-founded by CSE Ph.D. student David Goldfeld—took first place at the 2022 Minnesota Cup and expects to reach $50 million in annual revenue by 2027.

Looking to the future

The Midwest Sustainable Plastics Innovation Regional Engine (M-SPIRE), a U of M-led effort to drive the global transition to sustainable plastics, was chosen as one of 16 finalist in NSF’s Regional Innovation Engines competition with the potential for $160 million in NSF funding over 10 years.

“There are many universities in the U.S. that work on passenger cars and new technology for them, but there are very few who work on medium and heavy equipment or off-road vehicles. That is what we’re focused on,” said Kim Stelson, founding director of the Center for Compact and Efficient Fluid Power at the University of Minnesota.

per unit mass than batteries—and that factor of 40 is what has made them necessary in these machines,” he explained. “All a car has to do is move itself along a road. But something like an excavator also has to dig soil and dump it. So its power levels as you dig goes up and down, and the engine has to go fast or slow, while fully loaded or lightly loaded. All of this variation reduces the efficiency of the engine and it increases the emissions.”

While more cars are running on biofuels and electricity, their off-road cousins—specifically in agriculture, construction, forestry, and mining—have not changed much. Most of them still run on fossil fuels. Off-road vehicles represent 10 percent of transportation CO2 emissions in the United States, and this number will keep climbing if attention remains with on-road vehicles.

So, what’s the best net-zero solution for off-road vehicles? Is it going to be green hydrogen, green ammonia, or biofuels? Will we combust it or use fuel cells? Will some of these vehicles be fully electric, or will they combine electricity with other power sources? “The answer probably is yes to all of those options,” said Stelson. “There’s not a simple answer. W hat’s right for working in a mine might be different from what’s right for working in a corn field.”

LEADING ELECTRIFICATION WORKFORCE DEVELOPMENT

PARTNERSHIP RESULTS IN NATION’S FIRST GRAD CERTIFICATE PROGRAM IN ELECTRIFICATION The University of Minnesota’s Technological Leadership Institute (TLI), in collaboration with the Minnesota Department of Employment and Economic Development (DEED), Toro, Polaris, and Design Ready Controls, recently launched the Minnesota Center for Electrification Opportunity (MN CEO). This pioneering consortium will lead workforce development training and industrial upskilling through a partnership between the University of Minnesota and nationwide industry leaders in electrification. “The conversion of fossil fuel technologies to electric and hybrid power systems promises to be a decades-long process requiring enormous talent and organization,” said Allison Hubel, director of TLI and mechanical engineering professor in the College of Science and Engineering. “MN CEO is going to be a very important player in building the electrification infrastructure.” In December 2022, TLI partnered with Thermo King, a leader in transport temperature control solutions, to launch the nation’s first-ever graduate credential in electrification engineering.

The in-person and online program covers the breadth of technologies used to convert traditional mechanical systems into hybrid or electric platforms. It is designed for industry professionals and new college graduates— and driven by industry demand for a robust talent pipeline in fields including renewable energy policy.

ALUMNUS BUILDS A BETTER E-BIKE

LECTRIC IS ONE OF THE FASTEST-GROWING COMPANIES IN THE U.S. R o b b y D e z i e l ’s s t o r y i s a n inspiration to any engineer with an entrepreneurial spirit. As co-founder and chief innovation officer for Lectric eBikes, he gets to combine his knack for mechanical engineering, leadership, and design with his passion for clean energy. Fresh out of college in 2018, with mechanical engineering degree in hand, Deziel co-founded the company with his longtime friend, Levi Conlow. At the time, the national market for electric bikes was relatively limited and expensive. With inspiration and funding from Conlow’s dad, the two started their business with an ambitious mission: “to provide the most accessible and adventurous e-bikes ever.” They had a rough ride with their first model, which simply wasn’t selling. To find out why, they gathered extensive feedback from their target customers. The consensus was that

Deziel’s UMN experience gave him the confidence to lead his team at Lectric. He credits the mechanical engineering senior design capstone in particular. During this course, Deziel led five students in a 3M-sponsored competition to develop an impactresistant airdrop container for emergency medical supplies.

the bike looked uncomfortable and it was too hard to get on and off. “We basically went back to the drawing board,” said Deziel. They changed everything from the frame and wheel size to the seat, handlebars, and tires. They also made the bike foldable so riders could easily transport and store it. Enter the Lectric XP. The totally new e-bike model earned them $1 million in three weeks. Lectric went from selling just a couple bikes per month in 2019, to $2 million worth of XPs per month

“We had these talented people with their own strengths and abilities, and I was learning how to get the most out of them as a leader,” he said. “We had roadblocks, personality conflicts, design issues. We had to develop testing procedures and protocols, and get buy-in from stakeholders. That capstone experience was super beneficial to me and the closest thing to how it actually is out there in the real world.” — BY EVE DANIELS

IS GREEN STILL GREENER?

$20+ MILLION FOR CLEANER, STEADY, AND AFFORDABLE AMMONIA SUPPLY Everyone’s talking about ammonia. It’s a leading candidate in Earth’s race to decarbonize. The pungent gas does not emit carbon dioxide when burned, but making it requires electricity, which current manufacturers typically generate from fossil fuels like coal or natural gas. Prodromos Daoutidis is one of many researchers across the University of Minnesota who’s working on ways to green the process. “Ammonia is really responsible for feeding the world,” said Daoutidis, professor of chemical engineering and materials science. “It’s produced at a massive scale—200 million tons per year—and it’s used as the basis for fertilizers that can dramatically increase crop yields. If you look at the rate that ammonia production is growing, it really follows the rate of the population growth.” Yet, he add s, t he i ndu st r y is responsible for 500 metric tons of CO2 per year and nearly two percent of greenhouse gas emissions and fossil energy consumption. Ammonia that’s 100 percent powered by renewables isn’t a new concept. It just ha sn’t been a fea sible, commercial option. Daoutidis hopes to change that. “If you produce a chemical at a large scale, your rate of production is constant. It operates at a steady state as we say,” he explained. “In the case of green ammonia, because

FA L L 202 3

your feedstock is the wind or the sun, the feed stock fluctuates. This means you need a hugely oversized storage of hydrogen or a hugely oversized battery if you try to operate the system at a constant rate.” His research group has developed new design and operation algorithms that adjust for intermittency. “To build such a system, you cannot do a cookie-cutter design. You have to look at the particular location, wind or sun profile, and price of the electricity from that wind and sun capacity,” said Daoutidis, recipient of the 2023 AIChE Sustainable Engineering Forum Research Award for his significant technical contributions relative to the sustainability of products, processes, or the environment. “You also need to regularly adjust the level of production and create new safety precautions with regards to pressure or temperature, which will increase or decrease as you change the production rate.” Demonstration studies will be conducted at the U’s West Central Research and Outreach Center in Morris—site of the world’s first windto-hydrogen and ammonia model plant. The project builds on previous UMN green ammonia studies funded by the U.S. Department of Energy, totaling over $20 million. It also involves other colleagues in chemical engineering and materials (Qi Zhang, Alon

McCormick, Paul Dauenhauer), plus faculty in mechanical engineering ( W i l l N o r t h r o p), e l e c t r i c a l engineering (Sairaj Dhople), and the Hubert H. Humphrey School of Public Affairs (E. Harrington). International industry partners include Casale Switzerland and Shell. “We definitely see potential for using renewable ammonia for largescale storage of renewable energy, grid stabilization, regional-scale sustainable agriculture and energy, and community-scale applications,” Daoutidis said. “Minnesota has a huge tradition in ammonia. We have the experts and the infrastructure to be a world leader.”

turbulence eddies and water wave components explicitly resolved, and their coupled nonlinear dynamics.” Their study—backed by the National Science Foundation, U.S. Department of Energy, and New York State Energy Research and Development Authority—revealed the importance of ocean waves.

“We quantified the kind of impact, instantaneously and on average, they can impose on wind turbines,” Shen explained, “and how much energy can be harvested from an offshore wind farm.” To a w i nd f a r m oper ator, this means an opportunity to minimize the impact of wake effects and potentially increase overall power output. “The wind is in general stronger and steadier in the ocean than on land because it’s open—there are no mountains to block it. But offshore wind energy imposes a lot more challenges,” Shen said. “We wanted to simulate this on the computer, to sort of create this virtual reality first so, hopefully, we can provide some guidance for industry development in the coming years.”

“Before investing in these massive offshore wind turbine farms, it’s better to really understand

Most offshore turbines today are built in shallow waters or close to shore, with a fixed-bottom foundation and 6 to 10 megawatts (MW) of power. Shen and his colleagues are focused on those built in deep, open water. These 10 to 15 MW monsters with rotor diameters up to 240 meters will appear over the next 10 years, according to a report by the National Offshore Wind Research and Development Consortium, as shallow sites become scarcer.

PATENT LESSON

RESEARCHERS TO TRAP CO2 WITH PHOSPHATE KNOWLEDGE Valérie Pierre knows a lot about phosphorous. The chemistry professor and her research team spent six years developing a process to detect it and remove it from surface water. Now she’s taking that patented knowledge and applying it to carbon dioxide (CO2). Pierre has joined forces with two colleagues: Beth Stadler in electrical and computer engineering (also the college’s associate dean for academic affairs) and Emmanuel Detournay in civil, environmental, and geo- engineering (director of the U’s new $11 million Center for Interacting Geo-Processes in Mineral Carbon Storage). “The challenge is how much do we capture and what do we do with it after we capture it,” Pierre said. “Fortunately, we’re not starting from zero. We’re starting from every success we’ve had with phosphate.” That work—“Lanthanide Complexes for Catch-and-release of Phosphate Ions in Water”—is on its way to becoming a startup. Major companies are exploring partnering to commercialize it. Pierre is also driven by the fact that “nobody’s done this,” she said. The general approach of others involves aggressive electro-chemicals and a lot of energy. “We’re proposing something different—low-energy, passive, scalable,”

she added. “And we’re going for t he ocea ns instead of lakes because oceans are bigger and t h e r e ’s 45 t i me s more CO 2 in them than air.” Although only months into the research, the team has the molecules they need to experiment.

Like CO2, surplus phosphorus in any form is harmful. Although in the early stages, Pierre’s research has achieved exciting results.

“Now let’s see how much we can scale it up and optimize it,” Pierre said. “That’s why we have this collaboration—Emmanuel is really good at doing this at a really gigantic scale; Beth has the expertise to make the structural materials for the chemical receptors that can catch and transport the carbon dioxide. Our team really highlights the strength of this college and what you can do when you have scientists working together with engineers.”

New $144M Chemistry Teaching Labs Private philanthropy will play a key role in building the future STEM workforce The University of Minnesota began construction this fall on a new $144 million Chemistry Undergraduate Teaching Laboratories Facility. The renovation reimagines 95-year-old Fraser Hall on the Twin Cities campus. When completed, the updated 117,000-square-foot facility will house 18 active learning labs, tutoring and informal student collaboration spaces, and general purpose classrooms. Renovating and modernizing the outdated spaces—used by more than 5,000 undergraduate students each semester—will transform the way chemistry is taught and provide a strong foundation for our sustainability workforce. “We are incredibly grateful for elected leaders who are making a commitment to all of Minnesota through the University— from the shovel-ready project that puts Minnesota companies and crews to work, to the generations of students who will use these new labs as they become Minnesota’s future chemists, chemical engineers, physicians, veterinarians, nurses, dentists, teachers, entrepreneurs and more,” said University of Minnesota Interim President Jeff Ettinger. The project was made possible by an initial $3.2 million investment from the Minnesota Legislature in 2020 for project design and $92.6 million in 2023 capital funds. Private philanthropy and other investments are critical to covering the remaining one-third of the project’s cost. The project is expected to take two years, with the renewed Chemistry Undergraduate Teaching Laboratories fully opening for fall 2025 classes. “This project puts us on the leading edge of chemistry instruction and will enhance student outcomes and impact,” said College of Science and Engineering Dean Andrew Alleyne. “We look forward to meeting with alumni, friends, and companies and telling the story of this building’s importance and what it means to students and the state.” >> Read more and watch a timelapse video of the construction so far at z.umn.edu/chemteachinglabs.

Donors invest in education Postiglione Scholarship to support students and the planet

Edith “Edie” Postiglione’s concern for the environment manifested when she and her husband Gary took her 10-yearold daughter Cindy on a cross-country trip. Edie had enjoyed similar trips as a child, and she was eager to show Cindy the beautiful tree-covered mountains she remembered. But the mountains they saw were changed; the hills were nearly bald. From then on, Edie looked for ways to help the environment. She became a vegetarian, participated in a protest march over glyphosate and GMO food, received a citation for yanking buckthorn from the wooded park behind her home, and was even arrested in Chicago when protesting the KXL Pipeline. Later, she limited her actions to financially supporting environmental and animal welfare organizations.

Establishing the Edith (Edie) and Gary Postiglione Scholarship in Environmental Engineering in CSE is the result of their pondering. Gary’s younger brother, James, is also an alumnus—CivE ’82, MS ’87—and a longtime environmentalist like Edie. “By providing access to all the University has to offer— guidance of educated, insightful professors; research laboratories; and collaborative opportunities—we hope that intelligent, motivated students who receive the Postiglione Scholarship will develop implementable ways to save our planet,” she said. Sadly, Gary passed away unexpectedly on Nov. 1, 2022 just weeks after making their gift—but his legacy lives on. The first Postiglione Scholarship recipients will be selected in spring 2024.

As her 75th birthday loomed, Edie and Gary questioned what to do with their life savings. Gary had earned a bachelor’s degree in electrical engineering from the University of Minnesota in 1970. The couple met in 1976 when she started at Western Electric, where Gary happened to work. They

William Wade’s wife, Daler, surprised him with a trip from Texas to Minnesota for his 50th Reunion.

Reason to return

Reunion brings back fond memories of the University When Daler Wade saw the college postcard for the Class of 1973 Reunion, she knew it would be the “perfect” gift for her husband. William Wade grew up in Minneapolis, and over the years the couple would fly up from Houston (Daler’s hometown and where they currently reside) to visit his family. However, nearly a decade had passed since any return trips. “My wife put that postcard on the refrigerator and said ‘let’s do this for your birthday,’” recalled William. “So it was a great surprise—almost as good as a wonderful honeymoon.”

What was your favorite part about your 50th reunion? I found the department-hosted research showcase sessions, plus student group presentation, to be very informative and interesting. The lunch was great, and we had time for networking. It was also good to meet new alumni that I had not met before. Why are alumni events important?
