Thermodynamic Stability of Volatile Droplets and Thin Films Governed by Disjoining Pressure in Open and Closed Containers

Thin films are found to be the equilibrium configuration up to a certain value of the total density in a closed system, and beyond this value, there is a morphological phase transition to stable droplet configurations.

Gibbs Ensemble Monte Carlo Simulation of Fluids in Confinement: Relation between the Differential and Integral Pressures

It is shown that the differential and integral pressure are different for small pores and become equal as the pore size increases, and the ratio of the driving forces for mass transport in the bulk and in the confined fluid is also studied.

Nanothermodynamic Description and Molecular Simulation of a Single-Phase Fluid in a Slit Pore

It is shown how Hill’s method can be used to find new Maxwell relations of a confined fluid, in addition to a scaling relation, which applies when the walls are far enough apart, and it is shown that the subdivision potential is unequal to zero for small wall surface areas.



Thermodynamic stability of nanosized multicomponent bubbles/droplets: the square gradient theory and the capillary approach.

The analysis shows that it is impossible to stabilize arbitrarily small bubbles or droplets in closed systems and gives insight into metastable regions close to the minimum bubble/droplet radii.

Nucleation and cavitation of spherical, cylindrical, and slablike droplets and bubbles in small systems.

The theoretical study shows that the extrema or apparent spinodal points of the finite size loops are more closely related to (finite system size) bubble and dew points than to classical spinodals, and predicts that a homogeneous fluid is stable across the whole coexistence region.

Thermodynamic equilibrium and stability of liquid films and droplets on fibers

The modeling of liquid spreading and penetration into fibrous materials requires a better understanding of the interactions of thin liquid films and small droplets with single fibers. The wetting

The thermodynamical stability of the heterogeneous system with a spherical interface

A one component system, a liquid drop in equilibrium with its vapor, is studied in the discussion of the stability of a heterogeneous system with a spherical interface. Due to the complexity of the

Evaluation of finite-size effects in cavitation and droplet formation.

This work presents simple formulas which predict the finite-size corrections to the critical size, the nucleation barrier, and theucleation rates in the canonical ensemble very accurately and can be used to select an appropriate system-size for simulations and to get a more precise evaluation of nucleation in complex substances.

A method for Monte Carlo studies of phase equilibrium in confined systems is presented using an example of vapor-liquid equilibrium (capillary condensation and evaporation) in cylindrical pores employing Maxwell's rule of equal areas.

Fluid structure in the immediate vicinity of an equilibrium three-phase contact line and assessment of disjoining pressure models using density functional theory

We examine the nanoscale behavior of an equilibrium three-phase contact line in the presence of long-ranged intermolecular forces by employing a statistical mechanics of fluids approach, namely

Classification of Equilibrium Configurations of Wetting Films on Planar Substrates

We suggest a rigorous formulation of the problem of classification of equilibrium configurations of wetting films on solid surfaces and in pores taking into account capillary and adhesion forces. As
