Fulbright Grant Enables Takenaka to Write About Japanese 'Mothers Against War'

By Gail Hairston

Akiko Takenaka, associate professor of history and associate chair of the University of Kentucky Department of History, has been awarded a 2017-18 Fulbright U.S. Scholar grant to research and write her second book, to be titled “Mothers Against War: Gender, Motherhood, and Grassroots Peace Activism in Postwar Japan, 1945-1970.” She will spend the year in Tokyo with affiliations with Sophia University and Waseda University.

Electronic and Electrochemical Devices from Conductive Polymer Interfaces

Conductive polymer electrodes have exceptional promise for next generation electronic and electrochemical devices due to inherent mechanical flexibility, printability, biocompatibility, and low cost. Yet conductive polymers continue to suffer from lower conductivity than conventional semiconductors, which ultimately can limit performance.  Electrical conductivity can be increased by increasing the total number of carriers through a charge transfer reaction – oxidation or reduction.  The first half of this talk will focus on the use of spectroscopic methods to evaluate the effects of chemical, electronic, and physical structure changes of organic semiconductors that accompany charge transfer reactions at interfaces, with consequences on device performance. 

The second half of this talk will focus on the unique hybrid electronic-ionic conduction of conductive polymers, which has enabled novel electrochemical devices including bioelectronics.  Two key functionalities of potential-dependent doping at the polymer/electrolyte interface will be addressed: i.) rates of ion migration within the polymer and ii.) rates of charge transfer between a polymer and a redox active molecule.  The potential-dependent microstructure and relative distribution of electronic states (percent doping) are found to be critical in both mechanisms, although happen at different time scales.  For charge transfer, the presence of an inverted regime is observed for the first time, representing a path forward to redox selectivity at polymer electrodes.

Research Enhances Traditional Undergraduate Education

By Abby Schroering and Sara Shehata

As a land grant university, the University of Kentucky is committed to the advancement of knowledge through research. Even undergraduate students contribute significantly to that mission.

Students of any major, background and skill level have the opportunity to work with professors from all over UK, whether in labs, on faculty projects or even on independent projects that they design themselves.
