Congratulations to Ph.D. candidate Matthew Howell, the recent recipient of a prestigious NSF Graduate Research Fellowship. This fellowship will begin in Fall 2020 and continue through Spring 2023. Given the growing crisis of antibiotic resistant bacteria, Matthew—in collaboration with advisor Dr. Alfredo Angeles—is interested in examining the relationships between peptides, metal ions, and antibiotics. Together, they are searching for combinations that demonstrate synergistic killing of these bacteria.
Researchers from the University of Connecticut’s Sotzing Research Group are studying conductive and dielectric polymers for a number of applications, from color-changing fabric to medical applications of chemicals in cannabis to high-speed projectile launchers for the military.
The group is led by chemistry professor Gregory Sotzing. The group’s wide-ranging base of research is due to the number of applications for the polymers they study.
Sotzing explained that studying polymers really just means making new kinds of materials.
“We’re pretty much the people who make new materials, new compositions of matter. Then the engineers will take and test out these new things and see how well they work inside of certain kinds of applications,” Sotzing said.
The University of Connecticut has been recognized among the top producers of Fulbright U.S. Scholars from research institutions for the second time in the past four years.

Undergraduate student Eric Mohan ’20 (CLAS), recipient of an Office of Undergraduate Research award, shares his experience conducting research abroad.
“I am the recipient of the 2019 Office of Undergraduate Research (OUR) award, and I had the privilege of spending last summer in the laboratory of Professor Dominic Campopiano, in the School of Chemistry at the prestigious University of Edinburgh in the United Kingdom. This was an amazing experience to work with a renowned professor helping solve an unmet and urgent medical need related to the resurgence of antibiotic resistance. My project focused on the inhibition of an important enzyme found in many infectious bacteria, such as those causing Tuberculosis. I was tasked with synthesizing, modeling, and characterizing the pathway by which a compound, ERG240, blocked the branch chain amino acid aminotransferase enzyme. I used optically active coupled reactions in this work. We then co-crystallized the inhibitor with the enzyme and employed x-ray crystallography to fully understand the mechanism of the enzyme. My research was presented as a poster at the Fall Frontiers program 2019 at UConn, Storrs. Continue reading
The Department of Chemistry held their 2020 Research Safety Workshop for first year graduate students and Laboratory Safety Officers (LSOs) on Wednesday, January 15. The Workshop was organized by the Department Safety Committee and the Joint Safety Team (JST) in conjunction with EH&S. Presentations were made by Dr. Jing Zhao (Chair of the Department Safety Committee), Jessica A. Martin (Head of JST), Eric Krantz (Head of Teaching Laboratory Services), and Brent Lewchik (Chemical Safety Manager, EH&S). In all, 44 students were in attendance. A survey revealed that the vast majority of attendees found the material covered to be useful.
Enzymes provide optimal three-dimensional structures for substrate binding and the subsequent accelerated reaction. Such folding-dependent catalytic behaviors, however, are seldom mechanistically explored with reduced structural complexity. A recent article in Nature Communications, from collaborated research between Professor Jianjun Cheng at UIUC and Professor Yao Lin at UConn, demonstrates that the α-helix, a much simpler structural motif of enzymes, can facilitate its own growth through the self-catalyzed polymerization of N-carboxyanhydride (NCA) in solvents with low dielectric constants. The leading authors with equal contributions are Ziyuan Song (UIUC), Hailin Fu (UConn) and Ryan Baumgartner (UIUC). In the paper, Hailin Fu developed a new two-stage polymerization kinetics involving a Michaelis-Menton mechanism, which helped to prove the auto-catalytic nature of the NCA polymerizations. The research was facilitated by funding from the National Science Foundation (CHE-1709820 to J.C. and DMR-1809497 to Y.L.). The editors at Nature Communications featured the article in the Editors’ Highlights of recent research on Organic Chemistry and Chemical Biology (https://www.nature.com/collections/wdzvyhgxft/content/prabhjot-saini).

Professor Jim Rusling recently received START and SPARK Technology Commercialization Grants for Self-powered Bioelectronics.
Aiming to commercialize the world’s first battery-free implantable pacemaker, Professor Rusling and his team received two early-stage technology commercialization grants, START ($10K) and SPARK ($50K). Unlike current pacemakers which are battery-powered and require replacement surgery when the battery is drained, the new self-powered pacemaker uses nanogenerator technology to harvest the patient’s body energy and store it in a tiny biosupercapacitor to power pacemakers, potentially for the patient’s lifetime. Commercialization efforts of this product are led by VoltXon inc, a recent startup spun-off from Prof. Rusling’s research and led by Postdoctoral Fellow and CTO of VoltXon, Dr. Islam Mosa and graduate student Esraa Elsanadidy.
