Functional Material Laboratory

Building a materials science research field of the 21st century by utilizing space and non-gravity environments

As the International Space Station gears up its operations, high expectations are being placed on the experiments to let liquids float in the air without a container at the Japanese experiment module, Kibo. Our laboratory is also developing various kinds of floating-process technologies on the premise that they will be used at Kibo. Moreover, we are conducting research on the creation of new materials by establishing unprecedented methods such as floating through gas-jet levitation to attain non-convection and a high degree of supercooling that is similar to space environments. Additionally, we are conducting experiments to cool the floated liquid very quickly by using drop tubes, the free-fall section of which is 2.5 meters long. These methods have not been used anywhere else in the world.

FOR SOCIETY

We aim to introduce the quantum and electron theories to conduct research on the creation of new materials of the 21st century by using space environments while trying to make theories about the expression of properties that cannot be elucidated with conventional concepts. To that end, we are conducting experiments to create new materials such as next-generation semiconductors, high-performance permanent magnets, amorphous substances, quasi crystals and nanomaterials.
