Ion Exchange at Metal-Ceramic InterfacesPI: Frank Ernst, Case Western Reserve UniversityCo-PI: R. Raj, University of ColoradoAward Number: MET DMR-0208008 • Symmetrical electrodes, e.g. Al/Sp/Al do not create an EMF, but an asymmetrical electrode configuration, as shown on the right, creates a large EMF at elevated temperature, raising the specter of a new kind of high-temperature cell. • Metal electrodes made of the cations in the spinel lead to interdiffusion adjacent to the interfaces, which enhances mechanical strength of the interface.
Ion Exchange at Metal-Ceramic InterfacesPI: Frank Ernst, Case Western Reserve UniversityCo-PI: R. Raj, University of ColoradoAward Number: DMR-0208008 Education and Outreach • Yeonseop Yu, graduate student at Case, completed his PhD thesis and defended in 2006. Based on the skills he acquired in this project, he was hired by Samsung R&D, Korea. • Gurpreet Singh, graduate student at UCB, completed his masters thesis. • Myongjai Lee, doctoral student at UCB, was trained in UHV techniques, preparation of thin films, and electrical measurements revealing the mobility of ions in ionic crystals as a function of temperature. Broader Impacts • Frank Ernst, PI, gave an invited presentation on results from this research project in the symposium in honor of David Brandon at the TMS Annual Meeting in San Antonio, 2006. • Frank Ernst, PI, has been invited to present results from this research project at the Materials Science and Technology meeting in Cincinnati, 2006. • Our group has published a paper on results from this project in the Journal of Materials Science (Springer, 2006).
