Times Cited Count：0We conducted high-pressure neutron diffraction and quasielastic neutron scattering on a series of aqueous alkaline chloride solutions and clarified that the pressure- and ion-induced modifications to the water structure and diffusion originate from distinct physical mechanisms. Applying gigapascal pressure transforms the tetrahedral hydrogen-bonded network structure of water into a dense random packing, due to the collapse of the second and third coordination shells and an increase in the number of interstitial water molecules, regardless of the ion species. On the contrary, dissolved ions disturb the second shell but preserve the inherent tetrahedral network structure of water at ambient pressure. The anomalous trend of water diffusion from Li
to Cs under the ambient conditions disappears under the gigapascal pressure, and all the ions show a behavior of structure-making ions.

Times Cited Count：1 Percentile：28.15(Materials Science, Multidisciplinary)We present a comprehensive study of the high pressure behaviour of ReO using X-ray and neutron diffraction, Raman scattering and first-principles calculations to 15 GPa. We show that the ambient pressure 
structure converts at 0.7 GPa in a continuous phase transition directly to a cubic phase with space group 
and rhombohedral 
structures in this pressure range are an artifact due to an alteration of the sample by high-flux synchrotron X-ray radiation. The structural pressure dependence of the 
O samples are presented. The data shed light onto the unusual transition and densification mechanism due to progressive tilting of essentially rigid ReO
octahedra.

Times Cited Count：6 Percentile：63.87(Chemistry, Multidisciplinary)With the increasing importance of light-responsive materials, it is vital to analyze the relationship between function and structural changes induced by light irradiation. Small-angle scattering (SAS) is effective for such structural analysis. However, quantitatively capturing local molecular structure formation and molecular reactions at a scale of less than 1 nm via SAS is difficult. In this study, to analyze the structure of non-equilibrium phenomena in light-responsive materials, a new sample environment has been developed for a time-of-flight small- and wide-angle neutron scattering instrument (TAIKAN), comprising a UV-Vis irradiation system, UV-Vis absorption measurement equipment and photodetector. Simultaneous measurement of small-angle neutron scattering and UV-Vis absorption was achieved. This system was used to demonstrate the in situ observation of UV-Vis irradiation-induced structural change of micelles formed by a light-responsive surfactant sample in an aqueous solution.
