Adsorption of H2O on the V2O5(010) surface studied by periodic density functional calculations

Article Abstract:

Periodic boundary models and the density functional computations were used in studying the molecular and dissociative adsorption of a water molecule on the V2O5(010) surface. The calculations were done using CASTEP and DSolid computer programs. Results indicate that the adsorption of water molecule on the V2O5(010) surface occurs favorably while dissociation hardly occurs due to Coulombic repulsion of the lattice oxygens around the exposed vanadium center to the approaching oxygen of the hydroxyl species. It has also been observed that the vanadyl oxygen is the most favorable site for adsorption and dissociation.

Remarks on the interfacial tension in colloidal systems

Article Abstract:

A simple scaling reaction has been found to capture the concentration, particle-size and interfacial width dependence of the interfacial tension of coexisting colloidal dispersions.
