Micro tensile testing machine with the use of torque meter and linear actuator is introduced. It is expected that the mechanical properties of micro-material, such as foil, film and fiber are evaluated by using the micro tensile testing machine.
Although perchlorate ion is difficult to remove from water, muchconsumption of this anion would cause disturb growth of newborns and children. New molecular capsule, which removes perchlorate ion from water efficiently, was developed.
Popularization of products made from polylactic acid ( PLA ) as a bioplastic needs for its rapid degradation system. New PLA rapid degradation system using microorganisms is developed. In this system, crystalline PLA is melt within 24 hours.
