Developing a way to make lithium batteries safer, cheaper Lithium ion batteries, central to powering most modern technology, are potentially dangerous—the liquid electrolytes used in the manufacturing of those batteries Stephanie Wunder Michael Zdilla can be volatile. Now, two CST chemists have developed a way of creating a solid electrolyte that might reduce the battery’s volatility without decreasing its conductivity or increasing its costs. “There have been quite a few thrusts toward making lithium batteries safer, and one of them is to make everything in the battery a solid,” said Professor of Chemistry Stephanie Wunder, who is collaborating with Assistant Professor of Chemistry Michael Zdilla. “But in general, solids are less conductive.” Zdilla’s lab has developed a new, solid electrolyte matrix by dissolving organic liquids with lithium salts—like table salt but with lithium instead of sodium ions. Both materials are similar to those currently used in lithium ion batteries. A non-polar solvent is then added. “They are the same inexpensive materials that are going into lithium batteries right now,” he noted. “We found a new organic matrix that seemed to have extremely good low-temperature conductivity,” Wunder said. Though the matrix currently decomposes above room temperature, the researchers placed it in dry ice (-78 C). It held the same ability for conductivity as it did at room temperature. “I’m not aware of any material, solid or liquid, that has ever behaved like that for ion conduction at low temperatures,” Zdilla said. “This technology could be valuable for battery performance in extremely cold temperatures like space, the deep sea, the Arctic or Antarctica. Even in some more temperate places, it still gets cold enough that regular batteries do not perform well.” The researchers are confident the technology—once the material is stabilized above room temperature—has the potential to make lithium ion batteries better and safer.
Chemistry students awarded prestigious NSF fellowships
NEW FACULTY 2014 Graham Dobereiner, Assistant Professor Graham Dobereiner obtained his BS in chemistry in 2007 from Brandeis University and his PhD from Yale University in 2011, working in the groups of Robert Crabtree and Scott Miller. While at Yale, Dobereiner focused on the development and the mechanism of homogeneous Iridium-based catalysis. As a postdoctoral research associate in Richard Schrock’s group at MIT, he investigated the catalytic synthesis of nalkyl arenes via alkyl group cross-metathesis. Katherine Willets, Associate Professor Katherine Willets’ research focuses on the effectiveness of super-resolution imaging techniques. She is PI on two NSF awards and a DOE grant. She is also a co-PI on a $7.5 million grant from AFOSR for electrochemical imaging and mechanistic studies on the nanometer scale. She earned the 2013 Early Career award from DOE. Willets, who earned her PhD at Stanford, comes to Temple from a role as associate professor at the University of Texas at Austin.
Three Chemistry graduate students were awarded prestigious National Science Foundation (NSF) Graduate Research Fellowship Program grants in 2014. That program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering and mathematics disciplines who are pursuing research-based master’s and doctoral degrees in the U.S. The Department of Chemistry was one of only 31 departments nationwide to receive multiple fellowships and one of only 10 to receive multiple fellowships in organic chemistry. Chemistry’s 2014 NSF Graduate Research fellows are Megan Jennings, CST ’12, Samuel Markson and Christiana Teijaro. Selected through a national competition, the grantees receive an annual $32,000 stipend and $12,000 cost-ofeducation allowance for three years. Fellows also might be eligible for access to cyber infrastructure resources and international research collaborations. Teijaro, a member of Associate Professor of Chemistry Rodrigo Andrade’s lab, is working on the synthesis of certain natural alkaloids that inhibit the protein responsible for preventing cancer drugs from passing through cancer cells. “As much as I love teaching, I’m very excited to focus on my research 100 percent,” Teijaro said. “The chemistry department is conducting innovative, quality research that competes with any university.”
Sarah Wengryniuk, Assistant Professor Sarah Wengryniuk’s research interests include organic synthesis and methodology. She comes to Temple from a role as an NIHfunded postdoctoral research fellow at the Scripps Research Institute in La Jolla, Calif. In that capacity, Wengryniuk worked in collaboration with Bristol Meyers-Squibb on late stage functionalization of macrocyclic drug candidates. She earned her PhD in organic chemistry from Duke University in 2012, where she was an NSF Graduate Research Fellow.
Faculty Awards American Institute of Chemists Chemical Pioneer Award Ann Valentine, associate professor, was awarded the 2014 American Institute of Chemists Chemical Pioneer Award at a ceremony at the Chemical Heritage Foundation. The award is “for pioneering contributions to the understanding of the interface of inorganic chemistry and biological chemistry, focusing on the uptake, trafficking, and behavior of hydrolysis prone metal ions, particularly for elucidation of the bioinorganic chemistry of titanium.” Dreyfus Teacher-Scholar Award Michael Zdilla, assistant professor, received the Camille Dreyfus Teacher-Scholar Award, which supports the careers of talented young faculty in the chemical sciences. Administered by the Camille & Henry Dreyfus Foundation, the award provides an unrestricted research grant of $75,000. “We put together a very strong case,” said Zdilla, who was recognized for “Synthesis and Reactivity of Multimetal Systems Inspired by Biology.” He also won the prestigious Office of Naval Research Young Investigator Award in 2013. Kaufman New Investigator Award William Wuest, assistant professor, was named a recipient of one of the first new investigator awards from the Charles E. Kaufman Foundation. The two-year, $150,000 grant will support Wuest’s research on developing new molecules to function as therapeutics that could inhibit the processes of bacterial biofilms, which cause bacteria to become resistant to antibiotics.
