On density microheterogeneities in dilute supercritical solutions

Article Abstract:

The local density enhancement in dilute supercritical mixtures is largely the result of the near critical fluctuations in the solvent. The density enhancement caused by the near critical fluctuations is almost identical to those in dilute supercritical mixtures near the critical point of the solvent.

Range and energy of interaction at infinite dilution in aqueous solutions of alcohols and hydrocarbons

Article Abstract:

A study was conducted to determine the thickness of the layer of the water which is influenced by the presence of solute molecule and the interaction energy parameter between a solute molecule and a solvent molecule. Analyzing infinitely dilute hydrocarbon/water and alcohol water systems, it was found that the thickness of the layer of solvent affected by a solute molecule is equal to several molecular shells of water molecules. In addition, findings indicate that correlation volume is larger when the alcohol is solute as its produces higher disturbance in the water solvent.
