C. Y. Kong is associate professor in the Department of Applied Chemistry and Biochemical Engineering at Shizuoka University, Japan. He received his Ph.D in chemical engineering in 2001 from Graduate School of Engineering at Yokohama National University, Japan. And then he joined the Graduate School of Environment and Information Science at Yokohama National University. In 2008 moved to the Department of Applied Chemistry and Biochemical Engineering at Shizuoka University. His current research interests focus on synthesis of carbon nanomaterials (such as graphene and nanocomposite etc.) with environmentally-friendly chemical processes and measurements of thermodynamic properties in the fluids from liquid state to supercritical state.
Kong research group carries out fundamental and applied aspects of supercritical fluid. Fluid becomes supercritical state by increasing pressure and temperature above its critical point. Supercritical fluids which have liquid-like solvent power combined with gas-like transport properties can be suitable as substitute for the organic solvents having poor performance or the harmful organic solvents. For the reason, supercritical fluids work extremely well as novel processing medium for a wide variety of industrial applications. The supercritical fluid technology which is also one of environmentally friendly technologies is a promising alternative technology with a bright future, and has attracted the attentions of both scientists and engineers. The lab is involved in thermodynamic properties for various compounds including pharmaceutical by supercritical fluid chromatography and in carbon materials (such as graphene oxide, graphene, related nanocomposite material, etc.) for novel electrical and thermal properties and applications using supercritical fluid technology. Recently the lab has developed the chromatographic impulse response method that is being applied to the measurements of diffusion coefficient, partial molar volume and solubility of solutes in supercritical fluids. Furthermore, the lab has also developed the environmentally friendly conversion technique that can be used to prepare graphene sheets at relatively lower temperatures.
