The Inorganic Nanostructured Materials Group seeks out and fabricates a variety of novel nanoscale materials, such as nanotubes, nanowires, nanosheets and nanoparticles, and elucidates their microstructures and characteristics. In particular we employ chemical nanostructure manipulation and other techniques of nanoarchitectonics to artificially concentrate inorganic nanostructured materials and give them new functions in the aim of developing revolutionary new materials and devices that can be used in the environment and energy sectors. Given the members’ mastery of advanced electron microscope observation techniques, this group has successfully fabricated a large number of novel nanotubes and nanowires including MgO and ZnS. Our group was the first in the world to develop methods for the high-yield synthesis of ultra-pure BN nanotubes, and we developed a highly thermally conductive and insulative BN composite film. Achievements also include the discovery of a nanothermometer which was registered by Guinness as the world’s smallest thermometer.
