We have investigated structure and dynamics (translational and rotational motions) of liquids, solution mixtures, and ionic liquids at various conditions, such as low temperatures, high pressures, and nano-space, by using following methods.



Structure: Large-Angle X-ray and Neutron Scattering, Small-Angle Neutron Scattering (SANS)

Dynamics: NMR Relaxation, Quasi-Elastic Neutron Scattering

Simulation: Molecular Dynamics


X-ray experiments have been made at SPring-8,

and neutron scattering experiments have been carried out at J-PARC (Tokai) and ISIS (U.K.)
