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.

1/03/2018: Congratulations to Chris Dobrzanski on his first journal publication, which has been accepted to J. Chem. Phys.! 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.
The paper is available online at the J. Chem. Phys. webpage
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.
The paper is available online at: the GRL webpage

In addition to the unique experimental results, the paper presents a new model of deformation of a material with channel-like pores due to adsorption which distinguish the stresses normal to the channel and along the channel. The paper is available online at: the Langmuir webpage
5/19/2017: Gennady Gor gave an oral presentation "Elastic Properties of Confined Fluids and their Application for Characterization of Porous Materials" at the XI International Conference on Characterization of Porous Solids in Avignon. Two other contributions based on the collaborative work of Dr. Gor with ZAE Bayern (Germany) were presented at the conference by Christian Balzer.

4/26/2017: Armani-Christian Roxas has been awarded the 2017 Provost Undergraduate Summer Research Scholarship to carry out research in the Gor's group during the Summer 2017. Armani will be working on modeling interactions of soot particles with polycyclic aromatic hydrocarbons using molecular dynamics simulation.
3/17/2017: Gennady Gor presented his research on mechanical effects of adsorption at several seminars in St. Petersburg and Moscow: Molecular Physics Department at MEPhI, Institute of Problems of Mechanical Engineering Russian Academy of Sciences, St. Petersburg State Technological Institute, SCAMT laboratory at ITMO University, Laboratory of Physics of Nanostructures at St. Petersburg National Research Academic University.
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.
The paper is available online (open access) at DOI: 10.1063/1.4975001
1/28/2017: Gennady Gor presents a simple analytical model for condensation-induced restructuring of soot agglomerates at the 35th Northeast Regional Meeting on Kinetics and Dynamics. These are the first results on the collaborative project with Khalizov's group, supported by NJIT Seed grant.
11/20/2016: Dr. Gor organizes Minisymposium Fluids in Nanoporous Media at the Interpore-9 conference. The abstracts for poster presentations are still accepted. More information.
10/26/2016: Molecular simulations suggest that argon confined in a mesopore satisfies classical Tait equation, linear relation between elastic modulus and pressure. Moreover, the slope of this linear relation is the same as for bulk liquid argon. This is the main result of the new Dr. Gor's paper in J. Chem. Phys. This result can be used to determine elastic properties of nanoporous materials.
