The quantum chemically based COSMO-RS method meanwhile is broadly used in chemical engineering thermodynamics for the prediction fluid phase thermodynamic properties of bulk liquids and mixtures. Recently it has been extended to the prediction of the free energy of molecules in inhomogeneous systems as liquid-liquid interfaces, micelles and biomembranes.

Based on the free energy of the components at a liquid-liquid interface, the free energy of this interface, i.e. the interfacial tension can be predicted with low computational costs. Results for a wide range of interfacial systems are presented.
