Molecular dynamics simulations of disjoining pressure effect in ultra-thin water film on a metal surface

Molecular dynamics (MD) simulations are used to examine the disjoining pressure effect of a water thin film adsorbed on a metal surface. The model was validated against experiments and verified against previous MD simulations. The variation of vapor pressure with film thickness was examined for a water thin film adsorbed on a gold surface. The results agree well with the classic disjoining pres...

Effect of Disjoining Pressure on Surface Nanobubbles.

In gas-oversaturated solutions, stable surface nanobubbles can exist thanks to a balance between the Laplace pressure and the gas overpressure, provided the contact line of the bubble is pinned. In this article, we analyze how the disjoining pressure originating from the van der Waals interactions of the liquid and the gas with the surface affects the properties of the surface nanobubbles. From...

Disjoining pressure of discrete surface charges on thin aqueous films.

The disjoining pressure of charged parallel interfaces confining an electrolyte solution is to a large extent determined by the screening clouds of the surface charges. We evaluate the pressure in terms of the number density sigma of discrete charges and film thickness d and find, at sigmad(2) approximately 1, a crossover from the well-known law P approximately sigma(2) to a linear behavior P a...
