Structure and Dynamics of Liquids Using X-ray and Neutron Scattering
Physical chemistry is the study of the properties of matter and chemical reactions and changes based on the interactions between atoms and molecules. In our laboratory, we study substances in the liquid state. Liquids (especially water) can be found everywhere in the world of chemistry (laboratories, homes, factories, the global environment, and outer space).
Liquids (solutions) cannot ignore intermolecular interactions like gases, nor are they arranged in a regular pattern like solids (crystals). Therefore, elucidating the physical and chemical properties of liquids remains an evolving field. X-rays and neutrons have wavelengths corresponding to atomic distances, making them ideal probes for investigating the structure and motion of molecules in liquids.
By irradiating liquids with X-rays or neutron beams and analyzing their scattering, we study the microscopic properties of water on protein surfaces, water confined in porous materials, and functional liquids such as nanofluids and battery electrolytes. This research aims to elucidate the role of water in living organisms and the mechanisms underlying the properties of functional liquid materials.
Examples of the research
- Structural analysis of liquids with properties similar to water
- Structure of proteins in mesoporous materials
- Thermal conductivity mechanisms in nanoparticle dispersions
- Hydration structures in electrolyte membranes for fuel cells
