Differential permeability of an ultra-thin porous layer of monodisperse nanoparticles

In this paper, mathematical simulation of the motion of helium, methane, oxygen, and nitrogen molecules through an ultra-thin layer of a porous material composed by spherical nanoparticles of a similar size. The potential of the nanoparticle–molecule interaction is taken in the form proposed by V. Y. Rudyak and S. L. Krasnolutsky. The permeability layer with a size of about $10^{-7}$ m was studied by the method of classical molecular dynamics.
