Surfaces affect ion pairing
Article Abstract:
Computer simulations are carried out to study the pairing of a positive and a negative ion in the vicinity of hydrophobic surface. By using hydrophobic surfaces with different curvatures, it is found that the contact interaction between a positive and negative ion is strongly affected by the curvature of an adjacent surface, either stabilizing or destabilizing the ion pair and also the solvent-separated ion pair can be made more stable than the contacting ion pair by the presence of a surface.

Water's hydrogen bonds in the hydrophobic effect: A simple model
Article Abstract:
A simple analytical model is proposed to account for water's hydrogen bonds in the hydrophobic effect. This model supports the view that water's hydrogen bonding propensity determines the temperature dependence of the hydrophobic effect.

Charge asymmetries in hydration of polar solutes
Article Abstract:
The solvation of polar molecules in water is studied along with the hydration effects of polar solutes. The asymmetries in hydration free energies are mainly enthalpic, arising from the first solvation shell water structure.
