Faculty Information - Shumpei Ozawa

By utilizing container-free methods, including the microgravity environment on the International Space Station, as well as electromagnetic and gas-jet levitation techniques, we can achieve what was once considered difficult—such as melting materials at extremely high temperatures or achieving unique undercooled states where melts remain liquid even below their melting point. Leveraging these cutting-edge technologies, we are engaged in developing new materials with superior functionalities and properties, as well as conducting high-precision thermophysical property measurements.
