• Properties of matter, such as reactivity and functionality, are determined by the motion of the constituent electrons. For this reason we aim at developing new spectroscopic methods, by using electron Compton scattering, that would visualize the electron motion for stable species and most importantly the change of electron motion in transient species, which is the driving force behind any chemical reactions;
• (1) development of molecular frame electron momentum spectroscopy for momentum-space imaging of molecular orbitals in the three-dimensional form,
• (2) developments of multiparameter coincidence techniques for studies on stereo-dynamics in electron-molecule collisions,
• (3) development of time-resolved electron momentum spectroscopy for visualization of the change of electron motion in transient species.
• We hope to conduct collaborative research with a willing company for a practical application of this technology in industry, and we are also prepared to provide academic consultations to companies interested in our research.

• Conventional X-ray imaging methods that rely on X-ray attenuation cannot generate clear contrast in the observation of low-density materials such as polymers consisting of low-Z elements. However, the sensitivity to the materials can be improved drastically by X-ray phase imaging that detects X-ray refraction caused by the materials. X-ray Talbot or Talbot-Lau interferometry consisting of X-ray transmission gratings is now constructed in laboratories for X-ray phase imaging. X-ray phase tomography is also realized, enabling high-sensitive three-dimensional observation.
• X-ray phase imaging can be utilized for X-ray non-destructive testing of industrial products and baggage that cannot be checked conventionally.

We aim at appending a phase-contrast mode to micro-CT apparatuses and developing screening apparatuses in production lines.

• This group is engaged in basic and applied researches of "hydrides" for practical use in hydrogen energy system. The main subject is the exploration of advanced hydrogen storage materials which support hydrogen energy technologies such as fuel cells. Currently, we synthesize a wide variety of novel hydrides composed of lightweight metals with specific nano-structures using advanced techniques for crystal and electronic structure analyses. In addition to the hydrogen storage, we develop the wide research fields related to hydrides, such as fast lithium ionic conductors.

Besides the contributions in industrial progress through the material development for future hydrogen energy system and next-generation secondary battery, we positively provide technical assistance to organizations and companies concerned about our findings.
