Outline of research activitiesMicroscopes are very important tools for studying biological samples. However, most of the microscopes cannot measure the vibrational molecular imaging based on molecular information. At the moment, only two microscopes are measureable. One is the Raman microscope, and the other is IR microscope, those are complementary relations. But these are not perfect. Especially, the IR microscope has very low spatial resolution about 10 µm, because of the diffraction limit by the IR wavelength. This is a serious problem for a microscope. To solve this problem, we have developed IR super-resolution microscope with a sub-micrometer spatial resolution by using vibrational sum-frequency generation (VSFG) detection, and have reported the applications to various biological samples such as human hair, avian feather, living cells and so on. By using this microscope, we can observe not only the vibrational molecular image with high spatial resolution but also the molecular orientation and chirality images.

- Evaluation of high strain-rate mechanical properties of composite, metallic and polymeric materials
Outline of research activitiesIn recent years, composite and polymeric materials have been increasingly replacing conventional metallic materials in aerospace, civil, marine, rail and automotive industries. Some applications of composite and polymeric materials involve dynamically loaded components and structures. Therefore, there is a need to fully understand the dynamic behavior of composite materials for the analysis and design of composite and polymeric structures subjected to impact loadings. However, the mechanical properties of composite and polymeric materials under dynamic loading conditions are not well understood, because there are no standard impact test techniques.
Consequently, we experimentally and numerically examine the effects of strain rate on the compressive and tensile characteristics of composite and polymeric materials. High strain-rate stress-strain curves are obtained on the standard or modified split Hopkinson pressure bar (SHPB). Low and intermediate strain-rate ones are measured in an Instron testing machine.- Desired cooperation

Outline of research activitiesThe mechanical and electro-magnetic characteristics of metals are dependent on microstructures such as crystal orientation and grain diameter. In recent years, comprehensive studies have been carried out on thermo-mechanical control processing to improve physical properties of metallic materials without adding rare elements in order to save energy and resources. For example, high performance metals, such as ultrafine grain steel and magnetic steel, are developed by a combination of rolling and heat treatment. These metals exhibit uniform characteristics. However, it is more efficient if suitable characteristics can be generated at required positions. In our research, a new technology to control only material surface microstructure is being studied.

Outline of research activitiesMore than ten thousands people died caused fatal accidents in houses every year in Japan. Among them a number of the aged people died in falling down to flat floor even though without any steps. Floor slipperiness is usually represented as static friction coefficient at the slips in toe-off during last half of gait cycle. However, it is said that slips are also occurred at heel down to floor during first half of gait cycle. In order to evaluate floor slipperiness at heel down, it is necessary to measure the dynamic friction coefficient between footwear and floor under incremental vertical load during the heel down.
The wear of UHMWPE(ultrahigh molecular weight polyethylene) used in artificial joint is investigated more than 5 million cycles using joint simulator. The simulator is reproduced vertical load, flexion/extension, abduction/adduction and internal/external rotaion during gate cycle.
