Abstract

<p>Inelastic X-ray scattering (IXS) investigates an excitation in the terahertz region and reveals the viscoelastic properties of water and other liquids at the molecular level. From the proportional relationship between the wave number and the excitation energy, the high-frequency sound velocity which reflects intermolecular interactions can be obtained. The high-frequency sound velocity of water at room temperature is twice the adiabatic sound velocity, reflecting the characteristic water structure. In supercritical water, the density dependence of the ratio of the high-frequency sound velocity to the adiabatic sound velocity varies with the observed scale, suggesting the presence of clusters composed of several molecules. Nanoparticle-dispersed systems focused on industrial applications exhibit peculiar heat conduction. The dynamics of the liquid surrounding the nanoparticles are different from that of the bulk. It may affect the thermal conduction of the nanoparticle-dispersed system. The IXS measurements for carbon tetrachloride, benzene, and acetone clarified the relationship between the intermolecular interactions and the dynamics.</p>
