Enthalpy-Entropy and cavity decomposition of alkaline hydration free energies: numerical results and implications for theories of hydrophobic solvation

Article Abstract:

The first complete description of the solution thermodynamics of a series of linear, branched, and cyclic alkanes in water by computer simulations, including the enthalpy and entropy changes in addition to the solvation free energies is discussed. The findings obtained in this work have important implications for theories of hydrophobicity and suggest an approach to parameterize the free energies of apolar hydration and association.

Size-dependent enthalpy of condensation

Article Abstract:

A thermodynamic model which provides a way of calculating enthalpy and entropy changes and equilibrium pressures for the size-dependent enthalpy of condensation is discussed. The physical reasoning leads to the conclusion that the differences between these values for two liquid bodies of the same chemical nature are equal to the variation of the autoadsorption energies on their surfaces.
