Profile My specialty is solid state chemistry. The material systems handled by solid state chemistry are not limited to solid materials such as metals, ceramics, and polymers, but composite materials are also the subject of research. Furthermore, we are aiming to apply these composite materials to sensors and actuators by controlling the structure of fractal materials using a self-assembly process. In addition, we are also conducting research on oxygen ion conductors, Li ion conductors, electrode materials, and thermoelectric semiconductors as battery-related materials. The technical field targeted by these studies is phononics technology. The type of research is to propose new material design guidelines for the development of new material functions and the improvement of material properties. Research results will be announced through presentations at international conferences and publications in journals.
Research Field(Keyword & Summary)
  1. 1) Self-organizing processes involving solids

    This research is to realize the self-organizing process in the reaction field involving solids, unlike the solution system that is conventionally performed in biological and chemical systems. This self-assembling process is used to form self-assembled fractal aggregates, aiming to significantly improve conventional material performance. Previous studies have demonstrated that self-integrated fractal structures have dielectric properties that are effective in improving thermal properties.

  2. 2) Phononics material

    This research focuses on the transport characteristics of phonons, and especially when developing conductive conductive materials and highly efficient thermoelectric power generation materials with excellent waste heat and heat dissipation by controlling the direction of heat, catalytic materials used in various environments. Aiming for development. Previous studies have shown that the production of anisotropic crystals and their performance control can be controlled crystal-chemically by using the crystal morphology control of the material, and the effectiveness of the anisotropic material has been shown.
