Prof. Su Jeong SUH, Director of the Advanced Materials and Process Research Center for IT, deployed infrastructure for research equipment, including a semiconductor process clean room and ultra-precision material analysis equipment, by receiving the designation of Technology Innovation Center (TIC) from the Ministry of Commerce Industry and Energy in 1999. He conducted R&D projects using equipment built with TIC projects after receiving the designation of Regional Research Center (RRC) from the Ministry of Science and Technology in 2002. In addition, he was designated Regional Innovation Center (RIC) by the Ministry of Commerce Industry and Energy in 2006 to expand the industry-university cooperation research infrastructure and also continued to operate diverse education projects and business support projects, including workforce training for semiconducting processes, education in science and engineering for the unemployed, technical exchange meetings, and process technology support. Recently, he was selected as the Smart e-Plating Regional Innovation System (RIS) in 2012, Gyeonggi Regional Research Center (GRRC) by the Ministry of Commerce Industry and Energy, and as the base university of an ernergy cluster project by the Korea Electronic Power Corporation (KEPCO) in 2017. The group is expanding its research into the field of surface treatment processing and advanced sensors and works as a bridghead for intramural academic-industrial sectors.
The Magnetic Material Laboratory of the Department of Advanced Materials Science and Engineering has performed 10 technology transfers and 22 registrations of internal and external patents (7 external) in the past three years. Moreover, recently, Research Professor Young Il SONG has done research as a key person in the laboratory, easily producing eco-friendly multi graphene layer coated single or alloy metal nanoparticles (MGMNs) using a wire electric explosion method. These MGMNs have received widespread attention because of the unique structure of the multi-graphene shells encapsulating second-phase metal cores. The metal particles serve as a protection against environmental degradation effects and oxidation. Furthermore, these novel MGMNs induce unique electronic, optical, and magnetic properties due to quantum confienement and very high surface per volume ratio, which are undoubtedly important for the evolution of nanotechnology. In addition, these MGMNs can be used in various application materials such as energy storage materials, electrode paste, printable ink, catalysts, ferrofluids, and sensors.
Our researchers have unfolded not only the development of MGMNs by electric explosion method, but also the development of MGMNs with various metal core nanoparticles by chemical coprecipitation method. This technology also contributes to the increase of battery capacity and the enchancement of power moment output using graphene filme and thse metal nanoparticles on current collectors of lithium ion batteries. We are conducting further research on MGMN-based application devices.
