Specific-Field Analysis Team
The SFA team studies on the development of analytical and controlling techniques of various specific-fields so as to utilize them as a medium for various physical and chemical reactions, to aim at simplification of chemical processes and plants. The specific-fields include supercritical fluid, a space vibrated with ultra-high frequency over giga-hertz such as microwave, ionic solutions, nano-scale thin films between which giant electric filed is applied, and porous materials with highly structured functional molecules. We are also clarifying the mechanism of new physico-chemical phenomena appearing in the specific-fields where the above multi-functional media are concerned. For example, the merging flow of supercritical water over 374 and 21.8 MPa and ordinary water has been observed by the SFA team for the first time in the world with a visible s-shaped channel (the picture). Besides this, simple detection methods for poisonous species such as arsenic with a low cost and high sensitivity are developed using nano-structured materials. An atomically flat surface of oxide thin films to produce ultra-clean chemical environment is also developed based on the analysis of film-growth mechanisms with a hopping model on crystal lattices.
