Hybrid Nanostructured Materials as Critical Elements in Advanced Functional Materials and Devices - PLEASE NOTE THIS SEMINAR IS IN KEARNEY 112

Date: Thursday, May 17th
Presenter: Prof. Dong Ha Kim, Department of Chemistry and Nano Science, Ewha Womans University, Seoul, South Korea

Abstract


In the Polymer Nanohybrid Materials at Ewha Womans University, a comprehensive approach for the design and synthesis of multifunctional hybrid nanomaterials has been systematically performed to seek their potential applications as key elements in green nano- and bio-technology. Representative subject areas of interest include energy conversion and storage, environmental remediation, optical (bio-)sensing, light-emission, and memory devices. Of the numerous methodologies to achieve these goals, we actively utilize complementary self-assembly processes to construct well-defined hybrid nanoscopic objects suitable for target-oriented applications. Recently, we also pay special attention to surface plasmons as a versatile platform, based on which target-oriented properties can be obtained by integrating plasmonic nanostructures into the elements of optical (bio-)sensors, photovoltaic devices, photocatalysts, and light-emitting materials. In this talk, I’ll introduce our recent activities with a special focus on the synthesis and applications of tailored hybrid nanomaterials for plasmonic/perovskite optoelectronics, visible light active photocatalysis, electrocatalysis, light emitting diodes, non-volatile memory and biosensing.

Bio:
Prof. Dong Ha Kim received Ph.D. degree in the Department of Fiber and Polymer Science at Seoul National University in 2000. He carried out postdoctoral research activities in the Polymer Science and Engineering Department at the University of Massachusetts at Amherst (from 2000 to 2003) with Prof. Thomas P. Russell and in the Materials Science Department at the Max Planck Institute for Polymer Research (from 2003 to 2005) with Prof. Wolfgang Knoll. Then, he joined the Samsung Electronics Co. in the Memory Division of Semiconductor Research and Development Center as a senior scientist. He assumed a faculty position in the Department of Chemistry and Nano Science at Ewha Womans University in 2006, and currently is a Full Professor and Ewha Fellow. His research interests include development of hybrid nanostructures for energy storage and conversion, environmental remediation, memory devices, display devices, and biomedical diagnosis/therapy. He has authored 151 SCI publications and holds 29 Korean and 2 US patents. Currently, he is Fellow of Royal Society of Chemistry, Editorial Board Member of Scientific Reports and Advisory Board Member of Journal of Materials Chemistry A and Nanoscale.
