Order of wetting transitions in electrolyte solutions

Wetting layers in electrolyte solutions

2014 When a predominantly nonpolar mixture is in contact with a chemically ionizable substrate, thick wetting layers of a predominantly polar phase can form on the substrate. This paper considers the effects of added salt on such layers. In the limit of low salt concentrations, the equilibrium thickness reduces to a result previously derived by the author. In the limit of high salt concentratio...

Wetting transitions of Ne

We report studies of the wetting behavior of Ne on very weakly attractive surfaces, carried out with the grand canonical Monte Carlo method. The Ne-Ne interaction was taken to be of Lennard-Jones form, while the Ne-surface interaction was derived from an ab initio calculation of Chizmeshya et al. @J. Low Temp. Phys. 110, 677 ~1998!#. Nonwetting behavior was found for Li, Rb, and Cs in the tempe...

Wetting transitions in polydisperse fluids.

The properties of the coexisting bulk gas and liquid phases of a polydisperse fluid depend not only on the prevailing temperature but also on the overall parent density. As a result, a polydisperse fluid near a wall will exhibit density-driven wetting transitions inside the coexistence region. We propose a likely topology for the wetting phase diagram, which we test using Monte Carlo simulation...

Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

Molecular Modelling and Simulation of Electrolyte Solutions, Biomolecules, and Wetting of Component Surfaces

Massively-parallel molecular dynamics simulation is applied to systems containing electrolytes, vapour-liquid interfaces, and biomolecules in contact with water-oil interfaces. Novel molecular models of alkali halide salts are presented and employed for the simulation of electrolytes in aqueous solution. The enzymatically catalysed hydroxylation of oleic acid is investigated by molecular dynami...
