2009 Scholarships and Awards


Message from the Department Head e have experienced another year of change in CMBE, but are very well positioned to move ahead in spite of the State’s economic difficulties. Our new faculty, Cato Laurencin, Jeff McCutcheon, Bill Mustain, George Rossetti, Prabhakar Singh and Brian Willis, have all settled in and we are looking forward to welcoming our new Assistant Professor, Leslie Shor, in August. Twenty-six tenured or tenure-track faculty have their principal home in the department: 11 core faculty in Chemical Engineering (ChE) and 13 core faculty in Materials Science & Engineering (MSE), with the Head and Cato completing the team. Despite Dr. Laurencin’s busy schedule, as the Dean of the Medical School and Vice President for Health Affairs, his research activities continue to span both of our programs as he showed in his department seminar this year. By visiting our web site, you will see that we have also begun to expand our Biomolecular focus. Mei Wei and Ranjan Srivastava lead our Biomolecular research area, with four colleagues having joint appointments in Orthopaedic Surgery, two more in Biomaterials at the UConn Health Center, and Yu Lei, Yong Wang and Monty Shaw actively involved. Our Biomolecular Science & Engineering focus brings together bioengineering and biomaterials for students, with the great advantage of receiving an ABET-accredited degree in ChE or MSE. Our emeritus faculty remain active: Tom Anderson teaches in ChE; Bob Coughlin serves on the PTR Committee; Mike Cutlip continues to help with Polymath classes (his book is in its 2nd edition); Mike Howard remains a unique part of the Senior Lab experience; Art McEvily is still very active in research; Don Potter has replaced the XRD units and updated both the SEM and the TEMs for our seniors. Our Materials Advantage Student Chapter (ACerS, TMS, ASM and AIST) was named one of the five national Chapters of Excellence for the second time. Our student chapters of AIChE, MRS, Omega Chi Epsilon and Alpha Sigma Mu remain very active, with two ChE students winning poster awards in Philadelphia. Jonathan Winterstein, an MSE graduate student, won a Fulbright Award, which will take him to Graz, Austria, for nine months.

Research funding has already started to increase; I’ll just illustrate the breadth of our research with a few examples. Jeff McCutcheon and Prabhakar Singh received funding for their program linking energy and clean water. Prabhakar also received new support and samples from Rolls Royce. Bryan Huey was awarded an NSF Materials World Network grant to study phase-change memory devices. Yong Wang was the only Engineering faculty member to receive support from the State’s 2009 Stem Cell program for his work on hybrid peptide/RNA molecules for safe and efficient gene silencing in human embryonic stem (ES) cells. George Rossetti also received new funding from the Department of Homeland Security. Our graduate programs continue to remain busy. Our practice-oriented Master of Engineering (MENG) program including ChE and MSE courses brings a classroom experience directly to United Technologies and Pratt & Whitney employees as well as bringing students from these and other companies back to campus. In fall 2009, we will welcome another 25 new CMBE Ph.D. students. We were sorry that Lei Zhu decided to leave the green fields of UConn for the big city of Cleveland. Bob Weiss and Monty Shaw both retired from UConn this summer after 28 and 31 years, respectively! Monty plans to stay with us, spending more time on his writing and research activities. Finally, a few statistics! Last year, the faculty published 141 refereed journal articles (up 39% over last year) and 138 conference papers; we had 128 active research grants (up 30%); we advised 74 Ph.D. students (up 20%) and 42 M.S. students. Our department was also home to 273 undergraduates (up 12%). As you see, both ChE and MSE continue to flourish at UConn. We invite all our friends and alumni, in particular, to visit and see for themselves, especially before work on the new Engineering building begins! Dr. C. Barry Carter Department Head

Engineering Faculty Awarded Grants for Health Center Collaborations he University awarded grants to 11 multi-disciplinary research teams, of which four include engineering faculty members. The one-year start-up grants were made under a new UConn Health Center/Storrs and Regional Campus Incentive Grants (UCIG) program aimed at nurturing interdisciplinary research collaborations that are seen as having long-term promise and a strong potential for attracting significant external funding after the seed money concludes. The average funding level was $50,000.

professor in Chemical Engineering—along with UConn Health Center colleagues, principal investigator Rajesh Lalla of Oral Health & Diagnostic Sciences, Leslie Loew of Cell Biology and Douglas Peterson, Oral Health & Diagnostic Sciences—will investigate severe oral lesions, dubbed “mucositis,” that arise when cancer patients are undergoing high-dose chemotherapy and/or radiation therapy. The ulcers, said Dr. Srivastava, are quite painful and substantially compromise nutrition and oral hygiene

We were very pleased with the quality of the proposals and are excited with the potential that this competition has to stimulate creative, innovative and interdisciplinary scholarly activities. According to Suman Singha, Senior Vice Provost and Interim Vice President for Research, the UCIG program was developed to promote inter-campus research collaborations among researchers at the UConn Health Center and other UConn campuses. Commenting on the quality of Ranjan Srivastava submissions, Dr. Singha said “We were very pleased with the quality of the proposals and are excited with the potential that this competition has to stimulate creative, innovative and interdisciplinary scholarly activities.” Two of the awards went to faculty in CMBE: Ranjan Srivastava and Robert Weiss.

as well as increase risk for infections. He said that cancer patients experiencing oral mucositis can develop significant clinical complications, including dose reduction of their chemotherapy or interruption of radiation therapy, thereby reducing the effectiveness of the primary cancer treatment. Currently, there are few options for patients afflicted with mucositis. Dr. Srivastava and his colleagues seek to develop effective treatment modalities. “Our overall goal is to use detailed computational models derived from clinical and laboratory data to design new treatment strategies that minimize the severity of this important toxicity,” he said. “These models may enable us to maximize drug efficiency (that is, the cancer treatment) while minimizing mucosal injuries.”

Hartford Chapter of ASM Holds Materials Camp he Hartford chapter of ASM International organized the second Hartford Area Materials Camp, which took place at UConn on April 13. The half-day Materials Camps aim to introduce Materials Science & Engineering to high-school students. For this second camp, 24 high school students and six teachers from the Annual Multicultural Business Youth Educational Services Embarkment (AMBYESE), Yes I Can! Program and Hartford Public High School’s Academy of Engineering and Green Technology were exposed to a variety of hands-on demonstrations. They included brazing, heat-treatment, casting, and metal forming. Over 20 MSE undergraduate and graduate students volunteered for this camp as tour-guides or assistants at the different learning stations. The overwhelmingly positive response from the attendees has motivated the ASM Hartford chapter to consider a third camp in 2010.

Claire Weiss Wins SMART Scholarship laire Weiss, a doctoral student in Materials Science & Engineering, has won a coveted scholarship under the Science, Mathematics, and Research for Transformation (SMART) Scholarship for Service Program. Claire was one of approximately 200 students to capture the competitive award, from among 1,500 applicants. She is advised by Dr. Pamir Alpay, an associate professor in the Chemical, Materials & Biomolecular Engineering Department. Under the SMART scholarship, Claire will receive sponsorship from the U.S. Army, which will also provide her summer research opportunities and mentoring throughout the course of her degree program. On receiving news of the award, Claire said “I’m really excited, because the SMART scholarship gives me the opportunity to do research at a wonderful facility—the Army Research Laboratory (ARL)—and also to work in a great job with ARL after I graduate.” Managed by the Naval Postgraduate School (NPS) on behalf of the Office of the Secretary of Defense, the SMART program is administered jointly by the American Society for Engineering Education and NPS. It was created as a means to increase the number of civilian scientists and engineers working in Department of Defense laboratories. Claire is a member of the Functional Materials Group, and her research

focuses on the deposition, characterization, and electrical testing of complex oxide thin films for applications in tunable devices, such as phase shifter arrays for electrically steerable antennas. Claire is particularly interested in thin films based on barium strontium titanate (Ba{x}Sr{1-x}TiO{3}) or BST. BST is considered a top candidate for use in tunable microwave devices because of its highly non-linear dielectric response to applied electric field. Her current research is exploring many methods to improve the dielectric properties of BST thin films, such as using compositional grading to minimize the temperature dependence and doping to lower the loss. Tunable microwave devices are used in a broad range of commercial and military applications, from communications devices, therapeutic medicine and heating to GPS navigation systems, automobiles and satellite-based systems. Claire’s research is currently being funded by the U.S. Army Research Office and a Phase II SBIR sub-contract from SMI, Inc.

Claire Weiss deposits a precursor solution onto a substrate in the spin-coater machine. The spin-coater spins the substrate and the solution at a high speed to evenly coat the substrate and create a uniform thickness film.

Brody Receives 2009 Chalmers Award istinguished Professor of Materials Science & Engineering Harold Brody was recently honored by TMS, the Minerals, Metals & Materials Society, which presented him the 2009 Bruce Chalmers Award for outstanding contributions in the field of solidification science. Dr. Brody received the award in recognition for his “seminal contributions to microsegregation and back diffusion during dendritic solidification, in situ composites and peritectic solidification, and computer modeling of solidification processing.” Dr. Chalmers (1907-1990), regarded as the father of solidification science, was a famed applied physics professor at Harvard University, whose research was instrumental in advancing the electronics and microelectronics industries. For Dr. Brody, the Chalmers Award is a very personal honor. “Bruce Chalmers was a pioneer in solidification research. He was renowned for his ability to look at a complex process, recognize the most important Harold Brody, elements, and explain their inter- Distinguished Professor of Materials Science action in a simple and Engineering, works manner.

Biofuel Team Holds Workshops D

rs. Richard Parnas (Chemical, Materials & Biomolecular Engineering) and James Stuart (Chemistry) presented two workshops in January before audiences of high school chemistry instructors, at the request of the New England Association of Chemistry Teachers. The visitors, from schools across Connecticut, Massachusetts and Rhode Island, were introduced to the production and testing methods for biofuel processing using spent cooking oil. Dr. Parnas, director of the University's Biofuel Consortium and a member of the Polymer Program, said 20 teachers and five other attendees participated in the workshops to learn how they may construct small-scale demonstration reactors or integrate a learning module on biofuels into their chemistry lab courses. The Biofuel Consortium comprises students and professors across the University who share an interest in stimulating a biofuels industry within the state. In the consortium laboratory, researchers convert waste cooking oil collected from UConn dining facilities into clean-running fuel for the University's campus bus fleet. The team seeks to develop a large-scale reactor, and to introduce process improvements and alternative feedstocks aimed at making the process more cost-efficient. During the sessions, Dr. Stuart demonstrated the core ASTM tests—including chromatography, cloud point, flash point, acid number and viscosity metrics—used to assess biodiesel quality. Undergraduate Chemical Engineering students Steve Unker and Alyssa Midgette assisted in the presentations and laboratory demonstrations.

Hal Brody continued from page 5

Listening to him speak and discuss his research, I was impressed by his skill in translating the difficult into simple terms. He was a model for what a great professor should be. I’m probably one of the last people to receive the award who was influenced directly by Dr. Chalmers.” “As I built my own academic career,” he remarked, “I always tried to emulate the way he taught and thought. So it was especially poignant for me to be nominated by my former graduate students and to be selected by a panel of prior Chalmers Award recipients.” Solidification science is the study of the processes by which materials change from a liquid to a solid state. Dr. Brody explained that countless everyday objects, from highend cookware, sculpture, turbine blades, and automotive components to bicycle frames, are produced using a solidification process in the manufacturing sequence. Dr. Brody’s research has focused on the solidification of alloys. To make an alloy, metallurgists may heat two or more elements to a liquid phase, mix them together at a proportion that provides a uniform solution, and transfer the molten alloy to a mold where it solidifies in a manner that produces desired properties in the cast product. Dr. Brody said, Think of tea. Hot tea accepts more sugar than iced tea, with the sugar remaining bound in solution, to a critical tipping point: the solubility limit. When sweetened hot tea is cooled, sugar crystals can begin to form as precipitates. The solid crystals are richer in sugar than the sweetened liquid tea. When we blend metals in an alloy, the alloying elements, in general, are more soluble in the liquid than the solid phase.” He continued, “Solidification takes place over a range of temperatures, and the composition of the solid differs from the composition of the liquid from which it forms. Typically, to efficiently redistribute alloying elements between the liquid and solid phases, the solidifying crystalline solid develops tree-like, highly branched structures called dendrites.” The distinctive “jack frost” that forms on windows in winter is a familiar example of dendritic crystal formation. According to Dr. Brody, one of Dr. Chalmers’ principal contributions was in understanding how to solidify alloys to achieve a smooth, unbranched interface between the solid and the liquid that yields

a nearly defect-free structure, providing superior properties in semiconducting and magnetic materials. In contrast, much of Dr. Brody’s work has focused on fostering and manipulating dendritic solidification to attain premium properties in structural materials. Recent work relates to the casting and thermal treatment of engine blocks for the automotive industry. With support from an automotive consortium led by General Motors and the Department of Energy, Dr. Brody and colleagues are developing computer aided routines that simulate the evolution of dendritic structures. The results will be applied in the design and manufacture of high-quality components. To achieve this goal, he said, he and his team must discover and understand the behavior of complex commercial alloys and develop a practical database of the thermodynamic and kinetic properties of different materials. “We can manipulate the process by altering temperature and time, using different compositions, applying electromagnetic fields, etc. We try to understand exactly how the dendritic patterns form so we can control the microstructure. If we look at an alloy with the naked eye, it may look perfectly smooth and uniform. Using optical

things we do to increase strength result in a reduction in ductility. Controlling the dendrite structure and heat treatment is one of a few things we can do to simultaneously increase strength and ductility. We try to achieve a balance and also to consider cost.” Dr. Brody and his collaborators have also applied Professor Chalmers’ principles to suppressing dendrite formation during the directional solidification of complex alloys and ceramics, including peritectic phases. “The high temperature superconducting compounds are peritectic systems; that is, during solidification some of the liquid phase and some of the formed solid react to form the superconducting phase. Based on our research on the directional solidification of peritectic alloys, we hypothesized we could grow large, nearly defect-free crystals of the superconducting, peritectic phase directly from the liquid, but we never quite succeeded in getting the desired single phase microstructure.”

As I built my own academic career, I always tried to emulate the way he taught and thought. So it was especially poignant for me to be nominated by my former graduate students and to be selected by a panel of prior Chalmers Award recipients. and electron microscopes, and X-rays, we uncover the microstructure. We see the patterns of the dendrites and the particles that precipitate from the melt and the much finer particles that precipitate from solid solution. This is where the chemical, mechanical and electrical properties are manifested.” “We take advantage of what we know about how alloys ‘freeze’ in order to get the best dendritic pattern, and the best distribution and morphology (shape) of the precipitate particles” he explained. “After casting the alloy, we heat it to a high temperature below the melting range to dissolve the coarser particles, then ‘quench’ or rapidly cool the alloy to trap the alloying elements in solution, and then heat the alloy to a moderate temperature to form a host of very fine precipitates. In controlling the microstructure, we obtain required properties, such as high strength, toughness or ductility, and fatigue resistance. This is the challenge, since most

Despite this perceived failure, the team’s measurements of the superconducting and magnetic properties of the crystals grown, reported in the scientific literature, were the best results at that time. Dr. Brody commented, “This reaffirmed an often repeated lesson: the experiment that does not work as expected often reveals the most promising opportunity.” Dr. Brody joined UConn in 1991, when he was recruited as Dean of Engineering from the University of Pittsburgh. He remained Dean until 1997. He was a faculty member and administrator at the University of Pittsburgh for 25 years prior to joining UConn, holding positions as Chairman of the Department of Metallurgy & Materials Engineering and director of the Casting Industries Science & Engineering Institute.

Multi-Tasker Extraordinaire: James Bosse ames Bosse, who completed his B.S. degree in Materials Science & Engineering in May 2009, is a master multitasker who manages to juggle demanding coursework with original lab research and a part-time job. Oh, and he’s also a nationally competitive bowler who participates in tournaments about once a month. James, who hails from Berlin, CT, has worked in the research laboratory of Dr. Bryan Huey—assistant professor of Chemical, Materials & Biomolecular Engineering—since the summer of 2007. He has conducted a variety of studies involving atomic force microscopy, or AFM, a technique that allows researchers to image objects and processes at a fraction of a nanometer. “When I began working with Dr. Huey,” he said, “my work involved the use of AFM to efficiently and accurately separate DNA and protein strands by mass. I also researched the mechanisms behind ferroelectric domain switching and stability.” His Honors Program thesis involved the precise application of electrical voltages across ferroelectric/piezoelectric materials to view domain switching and actuation. James has made this type of measurement numerous times in the lab already, even presenting a poster at last year’s Materials Research Society conference. For the next step, the goal is to enhance measurement speed, requiring writing software using National Instruments’ LabVIEW to integrate, command and control a range

of lab equipment. The project exploits his skill in the use of this object oriented programming language that he acquired as an industrial intern at Emhart Glass Research Center. Throughout most of his high school years, James planned a career steeped in the mechanics’ milieu, like his father. College was nowhere on his horizon. However, a fateful meeting with his guidance counselor, and the counsel of an insightful chemistry teacher, placed him on a different career track. “In high school, I always enjoyed mathematics and science. My guidance counselor told me I should consider becoming an engineer.” James applied to just one school, UConn, and liked what he heard at an open house where engineering faculty and students discussed the engineering professions and displayed intriguing demonstrations. He found a home in the Materials Science & Engineering (MSE) degree program. “Materials science has the best faculty—a lot of young, energetic professors who are doing interesting research,” he said. He also dove into an array of activities that consume his days. During his first three years at UConn, James provided his peers with tutoring services in general engineering and MSE subjects as well as math, physics and chemistry. He also contributed his time as an officer in the Material Advantage chapter, serving as tutoring and scholarship chair, and began an internship with Windsor-based Emhart Glass in May ‘08. He continued working in Emhart’s process automation and simulation group throughout the school year, logging an average of 30 hours per week last semester.

At Emhart, James said, “I write LabVIEW software to automate data collection systems, such as thermal history via pyrometers and thermocouples. I also automated a density comparison system.” He recently cut back on his work hours to allow for more time in the lab. During his years at UConn, he has also stayed active as a top bowler, maintaining a schedule of league play twice weekly and competing in major tournaments monthly. He has won numerous national titles as a junior bowler and recently won his first adult tournament. A top student, James made the University’s Dean’s List for three consecutive years and was an Honors Program student. James’s undergraduate education was financed by academic merit and needsbased scholarships, including the ASM International George A. Roberts Scholarship, ASM Hartford Chapter Scholarship, the Capitol Scholarship Program, and a SMART Scholarship. Thriving amid a demanding, rigorous slate of activities comes naturally to James. “I owe my driven personality to three very influential people: my father, my maternal grandfather, and my old bowling coach, Bill Clay. They all stressed the importance of education, and a career filled with not only success, but also enjoyment. They have provided me with infinite wisdom over the years.” Post-graduation, James said “I plan to earn my doctorate in materials science, hopefully at UConn. I also plan to go for an MBA in finance. I’ve grown very interested in business and investing over the past year. As for my career, I’d like to ascend to a senior vice president, CEO, or CTO position.”

Outstanding Student Transforms Tragedy into Triumph For many people, crucial turning points define, or perhaps reroute, their life trajectories. oseph Zinski (‘10), an undergraduate student pursuing his B.S. in Chemical Engineering with a minor in Molecular and Cell Biology, aspires to a research career perhaps involving stem cell science. This ambitious aim emerges not only from his keen intellect, dedication and promise, but also a life-altering accident. One of nearly 700 students in his senior class, Joe graduated from Eastern High School in Voorhees, NJ. He credits two influential individuals with his decision to pursue a career in engineering: his structural engineer father and a much-admired high school teacher, AP Chemistry teacher William Crozier. When it came time to decide upon a college, Joe—a top student and outstanding swimmer—had many options, including Ivy League colleges, which, he said, “Seem to promote a cut-throat, highly competitive atmosphere among their undergraduates that I found unattractive.” During the summer sandwiched between his junior and senior high school years, he became acquainted with UConn through the Mentor Connection program, which allowed him to research organohydrogels in the laboratory of chemistry professor Challa Kumar. The experience was formative, so while many of his friends left for the University of Maryland, Joe decided upon UConn. “I liked the UConn engineering culture, which promotes a more cooperative learning environment and works to retain students. I also found the Storrs campus beautiful, with the mix of historic and state-of-theart new buildings.” Shortly after finishing his freshman year in 2005, Joe suffered a catastrophic diving accident in which he broke his neck, rendering him a quadriplegic. He underwent surgeries and countless hours of intensive physical therapy in his bid to reclaim not only mobility in his arms but also his educational dreams. The same qualities that made him a champion swimmer are helping Joe rebuild his

educational, personal and career goals. With unflagging determination, grit and humor—and aided financially by a generous merit-based Northeast Utilities Engineering Scholarship—he returned to UConn to continue his education.

Harvard Stem Cell Institute. The coveted internship is awarded to just a handful of non-Harvard students each year, and Joe is ecstatic. He plans to choreograph his summer schedule to accommodate both the Harvard Stem Cell and UConn SURF research projects. IN THE LAB: MODELING A BACTERIUM The Harvard internship is the first step toward one of Joe’s aims: to become involved in stem cell research, which holds promise of helping individuals afflicted with severe spinal injuries. A different type of research opportunity presented itself during the 2007-08 school year, when he

I liked the UConn engineering culture, which promotes a more cooperative learning environment and works to retain students. I also found the Storrs campus beautiful, with the mix of historic and state-of-the-art new buildings. Despite the challenges of his reduced mobility, including the hurdles of maneuvering campus in a wheelchair and continuing to maintain a rigorous schedule of physical therapy, Joe has remained a serious scholar, a member of the University’s Honors Program, a New England Scholar and a regular on the Deans List. He has also engaged in laboratory research over the last two years—in the area of his former nemesis, biology— and he was recently awarded a Summer Undergraduate Research Fund (SURF) grant to continue his research on campus this summer. In addition, Joe was accepted into a summer internship at the

began work in the laboratory of Pathobiology professor Dr. Steven Geary. There, he assisted doctoral candidate Steve Szczepanek in work involving the genomic sequencing of the bacterial pathogen Mycoplasma gallisepticum (MG), which causes respiratory and reproductive diseases in poultry. A serious affliction that is easily transmitted within the cramped conditions of most commercial poultry operations, the presence of M. gallisepticum often causes commercial poultry farmers to destroy entire flocks to eliminate the disease, resulting in an estimated $500 millions annually in the U.S. alone. Joe said continued on page 18

SPEAKER 1 BIO: SATYESH KUMAR YADAV earned his B.S. at the Indian Institute of Technology Roorkee (2004-2008), in Metallurgical and Materials Engineering. He began graduate studies at UConn in fall 2008 in materials science. Area of research: Ab initio study of II-VI semiconductors.

ABSTRACT: Although Zn based II-VI semiconductors are abundant, stable, and environmentally benign, their band gap energies are too large for optimal photovoltaic efficiency. If band gap can be engineered to desired level they can be excellent materials for photovoltaic application; especially in form of core/shell nanowire (that could improve the carrier collection in solar cells by reducing the excitation recombination rate). One way to engineer band gap is through strain. By using pseudopotential density functional theory calculations, we systematically study how the band gap, optical absorption of Zn based II-VI semiconductors changes with strain. We find that by suitably straining, band gap can be engineered to desired level. ZnO/ZnS core/shell nanowire with band gap of 2.07 eV matches with Shockley-Quiesser efficiency limit of 23%.

SPEAKER 2 BIO: XUEFEI WAN received a bachelor and master’s degrees from the Department of Materials Science and Engineering at Tianjin University, China. She entered the University of Connecticut in August 2006 and then joined Prof. Leon Shaw’s group in January 2007 to study the hydrogen storage materials. ABSTRACT: Currently, lithium borohydride (LiBH4) has been studied extensively as a reversible hydrogen storage materials for onboard energy carrier applications because of its high gravimetric hydrogen density (18.5 wt% H2). However, to date, LiBH4 has always been dehydrogenated/rehydrogenated at the high temperature because of its high temperature stability. Our study is focusing on destabilizing the LiBH4 system and decreasing its dehydrogenated/rehydrogenated temperature through nanoengineering and mechanical activation.

SPEAKER 3 BIO: ARIF MUBAROK received a B.S. in Materials and Metallurgical Engineering (MME) from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh in November 2004. He enrolled as a Ph.D. student at the University of Connecticut in August 2006. In January 2007, he became a Research Assistant in the Nano-structured Metallic Materials group. His supervising faculty is Prof. Rainer Hebert.

ABSTRACT: Bulk metallic glasses currently attract significant attention in the field of materials science with many unique and desirable properties, such as high strength, good hardness, good wear resistance etc. Thermal expansion behavior is very important but very few studies were done to elucidate the factors affecting the true thermal expansion of bulk metallic glass. Several factors affect the thermal expansion of amorphous alloy such as structural relaxation, viscosity, crystallization, heat-treatment condition etc and they are considered as non-reversible factors. We have synthesized a new Cu50Hf41.5 Al8.5 bulk glassy alloy in our lab and we used a new approach i.e. temperature modulated TMA to separate the true thermal expansion from other non-reversible affects.

M. gallisepticum lacks a cell wall, which makes treatment difficult because antibiotics that inhibit cell wall formation cannot be used. The aim of Dr. Geary’s research program on M. gallisepticum, funded by NSF and USDA, is to contribute toward the development of effective avian vaccines and treatments. Calling it a “small genomic bacterium, with just under 1 million base pairs, and the first I’ve gotten to know intimately,” Joe pointed out that M. gallisepticum also causes conjunctivitis in songbirds and displays degenerative evolution: over time, unused genes simply disappear from the genome. He said that although MG has been sequenced, only a portion of the bacterium's proteins, which are responsible for the bacterium’s virulence, have been identified. The research interested him, so when it came time to choose a project for his senior Honors thesis, he worked out an arrangement with Dr. Geary and Dr. Ranjan Srivastava, an associate professor of Chemical, Materials & Biomolecular Engineering, to co-advise his continued research on M. gallisepticum over the summer and through next year. The long-term project involves both “wet lab” and intensive computing. Under Dr. Srivastava’s guidance, Joe said, “I will study the metabolism of various cell types by using metabolic models and mass balances to create working digital models of the living cell. These models can be

18 [ CoMBinE ]

used to predict the use and production of metabolites [such as oxygen, glucose, CO2 and certain amino acids] as well as the growth rate of the cells. The model can then be easily modified to predict the metabolic response of deleting certain reactions or pathways. I’m building a metabolic model of M. gallisepticum with the aim of using it to predict which genes could be eliminated to create vaccines.” Joe’s development of a metabolic model will involve the use of complex software tools, including Pathway Tools, a bioinformatics software system that allows researchers to predict metabolic pathways based on an organism’s genome, along with a probability-based Bayesian classifier. For the M. gallisepticum portion, he will rely on genomic sequencing and annotations developed in Dr. Geary’s lab, largely by Research Associate and microbiologist Edan Tulman. After developing a computer model, in the Pathobiology wet lab, Joe will focus primarily on studying virulence factors in M. gallisepticum. “I’ll perform assays to monitor the uptake and discharge of certain metabolites. I’ll also measure cell growth. Then I’ll compare my experimental data against the model and modify the model as needed to ensure it accurately predicts the real performance of the bacterium.” In the final phase, working with other researchers in Dr. Geary’s lab, Joe plans to compare two similar strains of the bacterium, a wild strain and a clone that has been “evolved” such that it is non-virulent. This analysis will allow him to create

a more accurate metabolic model for the evolved, non-virulent strain of M. gallisepticum and to compare the virulent and non-virulent models to identify differences. The modeling results may then provide a basis for development of new drugs to treat the virulent strain. Joe will graduate with his B.S. degree in May ‘10, but he plans to continue his education by pursuing a doctorate in either metabolic engineering or stem cell research, with the goal of becoming an academic researcher. FUNDRAISING FOR DISABLED ATHLETES Joe’s commitment to improving the lives of individuals with spinal cord injuries extends beyond the research lab. Last year, he organized a fundraiser for the Swim With Mike Foundation (SWM), a University of Southern California-based organization that provides scholarships for former athletes who experienced a disabling injury or condition. Joe was awarded this merit-based scholarship in 2006 and it—in combination with the Northeast Utilities Engineering Scholarship—provided the financial support he needed to continue his education following his injury. SWM sponsors annual swim-athons at USC and the University of Hawaii to raise funds in support of these critical scholarships. Last year, Joe coordinated with the Honors Council and Student Athlete Advisory Council (SAAC) to host a very successful swim-a-thon/water volleyball tournament fundraiser at UConn.


Wang Awarded State Grant for Stem Cell Research rofessor Yong Wang of Chemical Engineering received one of two state grants awarded to researchers on the UConn Storrs campus. The state-funded grants are presented through the Connecticut Stem Cell Research Advisory Committee (SCRAC) to advance embryonic and human adult stem cell research in Connecticut. The funding program was approved by legislation in 2005 and continues through 2015. Dr. Wang’s proposal was evaluated against 77 statewide requests. A total of 12 seed grants were accepted for funding. Dr. Wang intends to engineer biomolecules to create novel nanostructures for drug delivery, regenerative medicine, and clinical diagnosis. In this particular research, he will use peptide and oligonucleotides as structural units to create hybrid nanostructures for RNA interference (RNAi) in hESCs. RNAi is a mechanism discovered by by two Nobel laureates, Professor Andrew Z. Fire at Stanford University, California, and Professor Craig C. Mello at the University of Massachusetts Medical School in 1998. It has been proven that RNAi is very important for both the functions of cells and the development of organisms. Furthermore, the discovery of RNAi has had a broad impact on life science and is expected to lead to novel medical applications in the future. RNAi has recently been applied to hESC studies for the discovery and validation of gene functions and the differentiation control by means of the delivery of small interfering RNA (siRNA), a 21-23 nucleotide (nt) duplex with 2-3 nt overhangs. However, contrasted with most

Winterstein Lands Fulbright Scholarship onathan Winterstein, a doctoral student in Materials Science & Engineering, has been awarded a Fulbright Scholarship to carry out research at the Austrian Centre for Electron Microscopy and Nanoanalysis—an institute renowned for its high-quality electron spectroscopy and microscopy. The Centre is associated with the Technical University of Graz (TU Graz). Jonathan, who earned his B.S. at Washington State University—Pullman, is advised by Dr. C. Barry Carter, Department Head of Chemical, Materials & Biomolecular Engineering. The Fulbright program is sponsored by the U.S. government and seeks to enhance cultural awareness and cooperation between U.S. scientists and professionals and peers around the globe. Jonathan’s Fulbright research will focus on ceramic fuel cell materials. He explained that ceramics play an important role in making next-generation clean energy technologies, such as solar and wind power, affordable and reliable. “Currently, cost is restrictive and the spread of solar and wind resources is not uniform; that is, not every part of the world receives equal wind or sunlight. Solutions to these barriers may come in the form of new technologies based on ceramic materials. For example, some ceramic materials can be used to convert solar heat into hydrogen that can later be used to power fuel cells. Hydrogen technology is a potential means to reduce cost and distribution difficulties of solar and wind power.” He continued “Many technologies to convert plant material to biofuels also depend on ceramics. Ceramic fuel cells, which convert fuel to electricity without burning the fuel, using clean hydrogen or biofuels are among the most promising technologies for clean energy generation.” His research at UConn has focused on the chemical and structural characterization of oxide ceramics and, in particular, cerium oxide, which is a promising material for energy technologies. A principal tool of his work is transmission electron

J

microscopy, or TEM, which permits researchers to understand materials at the nanometer scale. Jonathan seeks to control defects in the ceramic materials in order to optimize the performance of fuel cell materials. He explained that he hopes to answer many of the unresolved questions about cerium oxide materials, including the nature and management of defects and their influence on fuel cell performance. He also hopes to gain a better understanding of ceramic properties and structure with the objective of applying them in catalysis. Visualizing things on such a minute level requires the use of TEM, which he deems “critical to determining how the processing of materials influences the final performance of a product. During processing, nanometer-scale structures and defects are introduced into materials that must be controlled to produce a useful product. TEM can provide images and data about

these defects that are unobtainable by other techniques. Combining TEM with spectroscopy is particularly powerful for studying defects in materials.” Jonathan’s nine-month Fulbright award will provide him access to the Centre’s unique resources. “Few institutions in the world offer the state-of-the-art equipment available at TU Graz and no other institute has the same level of expertise in this field as that possessed by researchers at TU Graz.” Jonathan previously received a prestigious National Defense Science & Engineering Graduate (NDSEG) Fellowship, which has supported much of his doctoral research.

Engineering Students Help Rebuild New Orleans ay the phrase “spring break” and visions come to mind of bikini bacchanalia in Cancun, black diamond slopes at Vail, or maybe a quick cruise around the Caribbean. For some dedicated engineering students, the week was spent in rebuilding spirits and homes in New Orleans, which shows little progress even four years after the devastating events of hurricane Katrina. Among the students taking the long, 27-hour bus ride to New Orleans in March were junior engineering students Danielle LaPointe (Biomedical Engineering), Eric Dorsey and Mike Kowalczyk (both Civil Engineering), Lindsey Fink (Chemical Engineering), and senior Danny S. Lee (Mechanical Engineering). The students were part of several organized college groups from Connecticut making the trek. Eric, Danielle and Mike belong to the on-campus InterVarsity Christian Fellowship, while Lindsey and Danny were part of a non-denominational contin-

S

Canal area, where plant life has proliferated unhindered amid the ruined buildings and roads. Lindsey agreed that she drew on muscle, more than her engineering education, during the week’s toil. But like Eric, she felt her background helped her better understand the issues surrounding the levee reconstruction and why the levees ultimately failed during the hurricane. Eric worked in the Ninth Ward with about a dozen other volunteers and residents re-roofing a family home. He said the one-story home, damaged by 10-foot floodwaters, belonged to a family of nine who lost everything but an attic fan. The patriarch, an engineer by trade, and his three sons worked alongside the volunteers throughout the week—driven to speed by the government’s imposed deadline of 90 days for completion of certain repairs. The volunteers were shocked to

Not only was it great to see another part of the country and meet so many new people, I was able to help out other people in the process. gent that worked for an organization called “Rebuilding Together New Orleans.” A second-timer who volunteered during last year’s spring break as well, Eric has worked in construction jobs during the last two summers and found that his engineering training was helpful in understanding why New Orleans sustained such devastating damage. “As an engineer, you see the real problem was the failure of the levee system to withstand the storm surge.” He said the flood damage was still widespread throughout the Ninth Ward and Industrial

learn that families who cannot meet the repair deadline will have their homes foreclosed on by the government. The work Lindsey and Danny tackled involved demolition. Lindsey explained that the Rebuilding Together organization strives to avoid purchasing new materials in the rebuilding efforts, preferring to use recycled materials. “My team worked at taking apart an abandoned house, salvaging wood, nails, and other materials that could be reused in the construction of a house. It was neat to see that the organization was trying to recycle and reuse old materials.” The students were all motivated to volunteer by a desire to help others. Lindsey commented, “The alternative spring break program provides a convenient way to give back and help out those less fortunate. I had an amazing experience. Not only was it great to see another part of the country and meet so many new people, I was able to

help out other people in the process.” She left New Orleans with a strong sense of commitment. “Although it did take time and hard work to help others, I benefited and got so much more out of the experience than anything I could have put into it. The experience also helped to cement my desire to continue working to help others in the future and in my career.” During the week, Eric’s fellow UConn engineering students and InterVarsity members, Mike and Danielle, respectively painted baseboards and finished a bedroom at a home in nearby Slidell, and helped to bring order to rooms stuffed with donated clothing and other goods available to families still in desperate need. Eric rated the week’s experience a 10 out of 10 and said he plans to volunteer for the continued on nxt page

effort again next year. He summed up his experience this way: “The people of New Orleans feel forgotten. When you drive through the area, you see just how little has been done to reclaim the city, rebuild homes and lives. Entire sections of the city remain untouched. And you realize people are actually living in these destroyed homes, without utilities and basic services. So it was inspiring to be able to give something of ourselves toward making these people feel they’re not invisible.” Lindsey agreed that New Orleans appears to have fallen off America’s radar screen as an area in need. “The hurricane took place almost four years ago, and the government funding for relief efforts has greatly decreased. As a result, the revitalization of New Orleans and the surrounding areas would literally not be possible without volunteers. Volunteering gives you a sense of purpose and self worth; the work we did made a direct impact on someone else’s life.” Engineering students have done cleanup efforts in other parts of the hurricane-damaged Gulf Coast region as well. Senior Chemical Engineer Jane Bugbee and other members of the University’s Honors Program Council traveled to Pearlington, Mississippi during the 2008 spring break. Jane’s team was tasked with executing finishing touches—including indoor and outdoor painting and linoleum floor installation—on new houses built by the Pearlington Recovery Center for families still in government trailers. She said, “On existing houses that were salvageable, we did repairs on water-damaged parts; for instance, on one house that was on stilts, all the insulation underneath had been water damaged, so we replaced it.” She found the experience deeply meaningful. “I gained the ability to look at my life from a different perspective. The people down there lost literally everything to hurricane Katrina but were still upbeat, welcoming and grateful just for life itself.”

RESEARCH UPDATE: New Faculty Members rs. Yusuf Khan, Sangamesh Kumbar, Lakshmi Nair, Syam Nukavarapu, and Daniel Wan all joined the Department of Orthopaedic Surgery at UCHC and the Department of Chemical, Materials, and Biomolecular Engineering at UCONN Storrs last September. They make up a large part of the group that came from the University of Virginia with Dr. Cato T. Laurencin. The group is currently funded by NIH, NSF, DOD, and the Coulter Foundation to support their research interests, which include musculoskeletal tissue engineering, drug delivery, and biomaterials development, with each member pursuing individual aspects of these topics. Dr. Kumbar’s research program aims to develop mechanically competent, porous, 3-D scaffolds functionalized with nanofiber structures of natural origin for bone repair and regeneration applications. He has applied for a U.S. provisional patent on this technology. He has also submitted a grant proposal to the Wallace H. Coulter Foundation 2009 Early Career Translational Research Awards in Biomedical Engineering. Dr. Kumbar’s other research program aims to develop injectable particulate chemotherapeutic agent delivery systems and intends to submit a grant proposal to Prostate Cancer Idea Development Award sponsored by the Department of Defense. Dr. Nair’s areas of research focus on developing biomaterials for musculoskeletal tissue repair and regeneration. A significant part of Dr. Nair’s program is committed to using biocompatible and bioactive materials and molecules to modulate cellular response for scar-less tissue regeneration. Additional ongoing programs include development of injectable biocompatible polymeric delivery vehicles for soft tissue regeneration. Dr. Khan has been working on the development of biodegradable composite scaffolds for bone regeneration and repair, and methodologies to incorporate these scaffolds into current clinical treatments for fracture non-unions. He is also

Piezoelectric Materials and Devices ssociate professor George Rossetti and his team are developing new compositional families of piezoelectric ceramics that efficiently interconvert electrical and mechanical energy and find numerous applications in solid-state devices for actuation, sensing and energy harvesting. Materials with the highest electromechanical coupling efficiencies and greatest piezoelectric response tend to be found in multi-component perovskitestructured oxide systems that display complex hierarchical microstructures with features having characteristic dimensions ranging from just a few nanometers up to fractions of a millimeter. An important element of Dr. Rossetti’s research concerns the development of a phenomenological theory that can reproduce the generic phase diagram topologies of these systems and can be used to understand how microstructure evolution is influenced by the time-temperature-transformation history experienced during processing. Using this theory, Dr. Rossetti and his

A

collaborators have found it possible to explain why specific microstructural features are observed only in particular regions of these phase diagrams, providing new insights into how to tailor materials chemistry and processing to achieve properties that are optimized for device applications. His research on this topic is currently being applied to the development of high power sonar projectors under a UniversityLaboratory Initiative program sponsored by the Office of Naval Research, and to the processing of materials for anhysteretic actuators under a Short Term Innovative Research project supported by the Army Research Office. Dr. Rossetti also receives support from the Department of Homeland Security as a participant in UConn’s National in Transportation Security Center of Excellence. Working as part of a team with CMBE professors Rainer Hebert and Bryan Huey and Civil & Environmental Engineering professor Jeong-Ho Kim, research is underway to design and fabricate novel hybrid piezoelectric transducer architectures having both sensing and energy

harvesting capabilities. These transducers are intended to function as structural sensing elements that scavenge energy from ambient sources to operate without an external power supply. If successfully developed, these materials would find applications in performing autonomous structural health monitoring of bridges or other critical components of the transportation infrastructure. Dr. Rossetti currently has three doctoral students working under his direction and is continuing to build specialized laboratory facilities for carrying out processing studies and property measurements on dielectric, piezoelectric and other electroceramic materials.

Engineering When Nanometers Count ssociate professor Brian Willis joined the CMBE Department in January ’09, and serves as the Program Director for Chemical Engineering. His duties include teaching, research, and organizing departmental educational programs and outreach activities. Dr. Willis maintains a vigorous research program focused on engineering nanoscale structures for energy and electronics applications by controlling chemical reactions at surfaces. Using tools such as scanning tunneling microscopy and tunneling spectroscopy, his group investigates chemical reactions with nanometer scale precision. Combined with computational modeling, these experiments provide detailed insight into the growth of materials one layer at time using atomic layer deposition. Recent highlights include the reversible adsorption and

detection of single molecules using tunneling spectroscopy in monolithic nanoscopic tunnel junctions (MNTJs). These MNTJ devices are promising for biomimetic chemical sensors that distinguish molecules based on vibrational characteristics. Current activities involve scaling these devices for massively parallel sensor arrays. Other applications include energy harvesting through light detection and thermoelectric elements. Other activities include integrating epitaxial oxides with semiconductors and investigating substrate degradation in PEM fuel cells. Dr. Willis’ research is supported by several research grants from the National Science Foundation, Office of Naval Research, Department of Energy, and Intel Corporation. Dr. Willis will teach this first chemical engineering course in fall 2009.

RESEARCH UPDATE: New Faculty Members con’t. ince joining CMBE in August, assistant professor William Mustain has been extremely active. He recruited two graduate and four undergraduate researchers to his research group, which has initiated work on a diverse range of electrochemically oriented projects including, characterizing new non-carbon support materials for acid media electrocatalysts, quantifying the effect of impurities on the oxygen reduction reaction in anion exchange membrane fuel cells, developing a room temperature carbonate fuel cell, designing low hydrolysis anode electrocatalysts for direct borohydride fuel cells and corrosion mitigation of bipolar plate materials.

Recently, his Ph.D. institution, the Illinois Institute of Technology, recognized Dr. Mustain’s professional achievements by awarding him the IIT Outstanding Young Alumni Award, a top honor for recent IIT graduates. Dr. Mustain has also been quite busy writing proposals to both industry and federal agencies and will submit his first NSF CAREER proposal this summer. Finally, he has become quite visible outside of the university, becoming an active member in the Energy Technology Division of the Electrochemical Society, chairing sessions and organizing symposia. He has also been highly active in university outreach with local secondary schools and industry.

r. Jeffrey McCutcheon is the Northeast Utilities Assistant Professor in Environmental Engineering Education housed in the CMBE department. He is a center faculty at the Center of Environmental Sciences and Engineering and has courtesy affiliations with the Institute of Materials Science and the Connecticut Global Fuel Cell Center. He also has a courtesy appointment in the Environmental Engineering Program. Dr. McCutcheon’s research interests involve novel polymer processing methods applied to membrane separations for applications to sustainable water and power generation. He has 10 publications, 3 patent disclosures, and 19 conference proceedings based on his research on osmotically driven membrane processes, most notably forward osmosis. Dr. McCutcheon is considered a leader in the bourgeoning field of osmotically driven membrane processes. Dr. McCutcheon received his B.S. in Chemical Engineering

from the University of Dayton in 2002 and his Ph.D. in Chemical and Environmental from Yale University in 2007. Dr. McCutcheon held a post-doctoral position at Stony Brook University while working in a small startup company which was developing new thin film composite membranes for desalination. Dr. McCutcheon was technical group leader of the team of engineers developing this novel membrane technology. Dr. McCutcheon’s laboratory has quickly developed in his first year at UConn. He currently is advising 3 graduate students and 2 undergraduate honors students. His research interests are in membrane design for novel separation processes, transport phenomenon at polymer interfaces, and electrospinning polymer nanofibers for sustainable water and energy applications.

types of cells, hESCs are very fragile but resistant to transfection. As a result, safe and efficient siRNA delivery into hESCs remains a challenge. Therefore, there is a clear need to develop novel methods and reagents to improve siRNA delivery into hESCs. The objective of Dr. Wang’s research is aimed at developing novel hybrid molecules for siRNA delivery without the need of using viruses, transfection reagents, or physical tools. The hypothesis —that the peptides will perform like keys to open the closed doors in the cells and therefore achieve the efficient delivery— will be tested through three specific aims: 1. Synthesis and characterization of hybrid peptide/RNA molecules; 2. Characterization of binding, internalization and distribution of hybrid molecules; 3. Evaluation of gene silencing effect. This will be the first development of a bifunctional hybrid molecule-based delivery system for siRNA delivery. The hybrid peptide/RNA molecules are expected to provide not only a platform to enhance gene silencing in hESCs, but also a convenient tool of doing temporal control of gene silencing in hESCs. A successful outcome will strengthen hESC research and applications in the state of Connecticut. “These grants are further testament to the ground-breaking work in stem cell research that’s going on at UConn’s Health Center and Storrs campuses,” said UConn President Michael Hogan. “This further investment by the State in our stem cell programs reflects the leadership role that UConn researchers are playing in scientific discovery and state-of-the-art healthcare. I’m very proud of the work of our research teams.” The research is expected to be finished in two years.
