dc.description Gleb Yushin is an Assistant Professor of the School of Materials and Engineering at The Georgia Institute of Technology effective July 2007. He has received numerous awards and recognitions, including the Roland B. Snow Award from the American Ceramic Society, NASA Nano 50 Award, various best poster awards from the Electrochemical Society, Materials Research Society, and North American Membrane Society meetings, and multiple awards at ceramographic competitions. His recent work was featured on the cover of Nano Letters and was covered by Nature, Science, Advanced Functional Materials, Innovation Philadelphia Newsletter, Philadelphia Business Journal, and Frost & Sullivan, among others. Dr. Yushin received a M.S. in Physics from Saint-Petersburg Technical University (Russia) and a Ph.D. in Materials Science from North Carolina State University. Upon graduation in fall 2003 he joined Drexel University as a postdoctoral associate and soon was promoted to a research assistant professor position. At Drexel, Gleb has been leading the research efforts in nanoporous carbide derived carbon - based materials and devices for energy, environment and bio-related applications.

dc.description.abstract High power energy storage devices, such as supercapacitors and Li-ion batteries, are critical for the development of zero-emission electrical vehicles, large scale smart grid, and energy efficient cargo ships and locomotives. The energy storage characteristics of supercapacitors and Li-ion batteries are mostly determined by the specific capacities of their electrodes, while their power characteristics are influenced by the maximum rate of the ion transport. The talk will focus on the development of nanocomposite electrodes capable to improve both the energy and power storage characteristics of the state of the art devices. Carbon-polymer and carbon-metal oxide nanocomposites have been demonstrated to greatly exceed the specific capacitance of traditional electrodes for supercapacitors. Selected materials showed the unprecedented ultra-fast charging and discharging characteristics. Intelligently designed silicon-carbon-polymer composites showed up to 8 times higher specific capacity than graphite, the conventional anode material in Li-ion batteries, and stable performance for over 1000 cycles. In order to overcome the limitations of traditional composites precise control over the materials' structure and porosity at the nanoscale was required. en_US
