Aqueous solutions next to phospholipid membrane surfaces: Insights from simulations

Article Abstract:

The thermodynamics of hydration are studied using new calorimetric methods that allow for separate determination of the energetic and entropic contributions to the dehydration process. Structural and dynamical properties of water next to biomembranes are similar to properties of water next to other biologically important macromolecules such as DNA and proteins, and a very large amount of both experimental and computational work is done to study water at these surfaces.

Specific ion effects at the air/water interface

Article Abstract:

The rapidly expanding body of computer simulations of ions at the air/water interface is reviewed. Conclusions reveal that a new view of inorganic ions at the air/water interface is emerging from recent simulations and surface selective spectroscopic experiments and the surfaces of aqueous electrolytes are described as inactive and practically devoid of ions.
