The work "Density Functional Theory Model for Adsorption-Induced Deformation of Mesoporous Materials with Non-Convex Pore Geometry" reports the results obtained by Dr. Andrei Kolesnikov during his recent research stay at NJIT as a DAAD scholar.
Using the classical density functional theory we have modeled gas adsorption in CMK3-type of materials, where the pores are formed as spaces between the hexagonally arranged rods. Furthermore, we calculated the solvation pressure induced by gas adsorption, which drives the adsorption-induced deformation process. Our predictions show a qualitatively different behavior as compared to the cylindrical pore model, frequently used for these materials.

In this work we simulated liquid argon in model nanopores and calculated its compressibility. We showed that along with the pore size, the pore shape affects the elastic modulus of confined argon: argon is a spherical pore is stiffer than in the cylindrical pore of the same size. This observation suggests that elasticity of confined fluids can be used as a quantitative measure for calculation of pore size distribution of a nanoporous sample.

12/28/2017: Our new paper "Gassmann Theory Applies to Nanoporous Media" (by Gennady Gor and Boris Gurevich) came out in Geophysical Research Letters. Gassmann theory describes the propagation of sound waves in fluid-saturated porous media, which is essential for exploration geophysics. Does this theory apply to nanoporous media, such as shales? For shales it still remains an open question, yet our paper showed that for a model nanoporous medium, Vycor glass, the Gassmann theory works. In order to apply the Gassmann equation for such system, the fluid properties have to be modified to take into account the solvation pressure in the nanopores. Our findings set up a theoretical framework for investigation of fluid-saturated nanoporous media using ultrasonic elastic wave propagation.

2/24/2017: Gennady Gor has published an invited review paper on adsorption-induced deformation of nanoporous materials in the journal Applied Physics Reviews. Nanoporous materials play an important role in many chemical engineering applications, in particular they are used as adsorbents. When fluids get adsorbed in the pores that are only a few nanometers wide, the intermolecular forces between the fluids and solids induce very high pressures. These pressures can reach hundreds of atmospheres and cause noticeable deformations even in stiff solid materials. The review paper discusses a variety of cases where these strains are significant: change of permeation of zeolite membranes, swelling of coal, etc. and presents the state-of-the art theoretical understanding of this phenomenon.
