Fundamentals and Applications of Nanoelectrokinetic Ion Concentration Polarization Devices
Ion Concentration Polarization (ICP) phenomenon is a traditional electrochemical ion transportation process and appears as a steep concentration gradient near nanoporous membrane under dc bias. The major function of ICP is an active ion control by an external electric field so that it is significantly useful to study the new ion transportation through nanoporous junction (or membrane) and develop novel engineering applications. As examples, high energy efficient purification system, bio-sample selective preconcentrator, and ionic field effect transistors will be introduced, and problems behind these applications such as instability will be also discussed.
Professor Sung Jae Kim received the B.S. and M.S. degree in department of Chemical Engineering of Pohang University of Science and Technology, Pohang, Korea, in 1998 and 2000, respectively. He received his Ph.D. from department of Chemical Engineering and division of Mechanical and Industrial Engineering from the same university in 2005. He joined MIT as a postdoctoral associate in December 2005 and he continued to work as Research Scientist at the same group in MIT. From 2012, he joined Seoul National University as an assistant professor at Department of Electrical and Computer Engineering and promoted to an associate professor in 2016. His current research program focuses to the fundamental nanoscale electrokinetics especially ion concentration polarization phenomenon and its engineering application in the field of energy, environment and bio sector.
