Abstract:
Aqueous pure silica zeolite-based microporous liquids, also known as microporous water, show interesting properties based on their internal hydrophobic and external hydrophilic chemistry. Here we show, using 17O NMR spectroscopy that the water, in which the nanoparticle zeolites are dispersed, exchanges with the external surface of the pure silica material.

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)...
