Hokkaido University Institute for Chemical Reaction Design and Discovery

研究概要

I am working in the highly interdisciplinary research fields of theoretical and computational chemistry, physical chemistry and materials science. We cover a broad range of fundamental questions related to energy conversion and storage problems (catalysis and batteries), electrochemistry, nanocatalysis and nanoscience, surface and interface chemistry, theoretical design of novel functional materials, chemical transformations and control for chemical processes by nanomaterials and atomic clusters. My goal is to develop a quantitative description of materials, to identify factors controlling their properties, and to use this knowledge for a rational design of innovative materials via balanced combination of theory, computations and experiment.

An equally intriguing area of research is nanocatalysis. It focuses on the study of the catalytic properties of atomic clusters and nanoparticles – an embryonic form of matter that is intermediate between atoms and their bulk counterpart. Physical and chemical properties of nanoparticles depend on their size, structure, and dimensionality and hence can be controlled by these factors. This fact gives unique opportunity for an atom-by-atom design of nanomaterials with tailored properties. We focus on theoretical elucidation of various mechanisms affecting physical and chemical properties of materials at a nanoscale.
