Disjoining pressure of an electrolyte film confined between semipermeable membranes

Effect of disjoining pressure in a thin film equation with non-uniform forcing

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...

Application of Semipermeable Membranes in Glucose Biosensing

Glucose biosensors have received significant attention in recent years due to the escalating mortality rate of diabetes mellitus. Although there is currently no cure for diabetes mellitus, individuals living with diabetes can lead a normal life by maintaining tight control of their blood glucose levels using glucose biosensors (e.g., glucometers). Current research in the field is focused on the...

Description beyond the mean-field approximation of an electrolyte confined between two planar metallic electrodes.

We study an electrolyte confined in a slab of width W composed of two grounded metallic parallel electrodes. We develop a description of this system in a low coupling regime beyond the mean-field (Poisson-Boltzmann) approximation. There are two ways to model the metallic boundaries: as ideal conductors in which the electric potential is zero, and it does not fluctuate, or as good conductors in ...
