The aim of this communication was to expand the results of numerical analyses performed by Sun et al. on their experimental solubility of fenofibrate in aqueous mixtures of ethanol and acetone at 298.15 K, in terms of the evaluation of the preferential solvation of this compound by the organic solvents and water in the saturated mixtures based on the inverse Kirkwood-Buff integrals (IKBI). ...

The kinetics of the reaction between malachite green and hidroxide ion was studied in several binary mixtures of water with alcohols (methanol, ethanol, 1-propanol, ethylene glycol and glycerol) and aprotic solvents (DMSO). In all solvents, the selective (preferential) solvation is present. A method for estimating the dielectric constant in the solvation shell and the constant of preferential s...

Recent NMR experiments and molecular dynamics simulations have indicated that rhodopsin is preferentially solvated by omega-3 fatty acids compared to saturated chains. However, to date no physical theory has been advanced to explain this phenomenon. The present work presents a novel thermodynamic explanation for this preferential solvation based on statistical analysis of 26,100 ns all-atom mol...

The effects of cosolvents on the solubility and hydration of small nonpolar solutes in solution has been investigated using a combination of molecular dynamics simulation and Widom particle insertion calculations. Results were obtained for helium, neon, argon, and methane solutes in solutions of sodium chloride, ammonium sulfate, calcium chloride, ammonium acetate, tetramethylammonium chloride,...
