Abstract:
The temperature dependencies of in situ small-angle X-ray scattering (SAXS) of water adsorbed and of adsorption isotherm of water in hydrophobic carbon nanopores were measured over the temperature range of 293 to 328 K. The structures of water nanoclusters adsorbed in the nanopores were determined with the density fluctuation analysis of in situ SAXS data. The difference of the density fluctuations between adsorption and desorption was ascribed to the water structural difference. The structural transitions of the water nanoclusters were observed around 318 K for adsorption and 308 K for desorption.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
