Scope of Section

Various inorganic materials are inevitable for the energy technologies including its conversion, storage or transport. In our laboratory, structural tailoring of high performance ceramics for advanced gas turbine, ceramic heat-shielding coating by thermal spraying for super/hyper-ultrasonic airplane and power generator, and oxide thermoelectric materials, which have low environmental load and high efficiency, are studied.
