| Profile |
After obtaining a doctoral degree (science) from Tokyo Institute of Technology through crystal structure analysis research of inorganic materials and getting a job at the National Institute for Materials Science (NIMS), I conducted research to develop new analytical methods for chemical states and chemical changes of materials by X-ray method. I am also developing functional materials and chemical reaction processes from an analytical point of view. Since moving to TCU, I have been further advancing research on material development and chemical reaction analysis using X-ray methods. |
| Research Field(Keyword & Summary) |
- (1) X-ray analysis
Development of new X-ray equipment for analyzing the composition, element distribution, chemical state, and detailed crystal structure of inorganic materials with complex structures and substances during chemical reaction.
- (2) Hydrogen energy
As a method for producing clean energy hydrogen without emitting new carbon dioxide, we are studying chemical reactions using waste and inexpensive substances as raw materials. In particular, we are considering the use of scrap iron and are also studying the synthesis of ammonia, which becomes a hydrogen carrier.
- (3) Utilization of waste
We are studying the reduction of carbon dioxide and its use for chemical reactions. In addition, in order to promote the utilization of slag generated during steel production, the crystal phase contained, its state, and chemical reactivity are analyzed. We are conducting research to chemically treat these wastes and synthesize useful materials.
