文摘

Gas-expanded liquids (GXLs) are a new and benign class of liquidsolvents, which may offer many advantages for separations, reactions, and advanced materials. GXLs are intermediate in propertiesbetween normal liquids and supercritical fluids, both in solvatingpower and in transport properties. Other advantages include benignnature, low operating pressures, and highly tunable properties bysimple pressure variations. The chemical community has only justbegun to exploit the advantages of these GXLs for industrialapplications. This Account focuses on the synergism of experimental techniques with theoretical modeling resulting in a powerfulcombination for exploring chemical structure and transport in thecybotactic region of GXLs (at the nanometer lengthscale).
