Sang Sub Kim joined the Department of Materials Science and Engineering, Inha University, in 2007 as a full professor. Before joining Inha University, he was an associate professor in Sunchon National University in 1996-2001 and an associate professor in Chonnam National University in 2002-20o6. He received his B.S. degree from Seoul National University and his M.S and Ph.D. degrees from Pohang University of Science and Technology (POSTECH) in Material Science and Engineering in 1987, 1990, and 1994, respectively. He was a visiting researcher at National Research in Inorganic Materials (currently NIMS), Japan for 2 years each in 1995 and in 2000. In 2006, he was a visiting professor at Department of Chemistry, University of Alberta, Canada. In 2010, he also served as a cooperative professor at Nagaoka Universityof Technology, Japan. Prof. Sang Sub Kim has published 210 peer-reviewed SCI papers and serves as Editorial Board Members of Scientific Reports, Metals and Materials International, Journal of Sensors, and Electronic Materials Letters. His research interests include the synthesis and applications of nanomaterials and functional thin films, and chemical gas sensors based on nanowires and nanofibers.
Abstract: Over the past several years, the detection of toxic gases has become increasingly important for monitoring environments. Accordingly, significant efforts have been made to realize highly sensitive and selective gas sensors not only by the creative design of new materials but also by innovation in sensor structure and architecture. One of the routes to improve this sensing capability is to use nanostructured materials such as nanowires. In spite of significant progress on chemical gas sensors based on oxide nanowires, their actual application remains a challenge.In this talk, overview on the currentstatus of nanowire sensors and their prospect will be presented. In particular, the following items will be discussed; synthesis of networked nanowires, functionalization aiming for the electronic and catalytic sensitization, approach to selective sensing, application of core-shell structures, and powerless sensing by self-heating.
