Permeability of the tunnel of spherical nanoparticles

In this paper, we investigate the ability of test molecules to overcome the energy barrier existing in the gap between two rows of spherical nanoparticles. A tunnel of particles is the simplest structural element of a composite porous material. The ability of molecules to associate with nanoparticles and then move to a more powerful field of repulsive forces determines filtration properties of porous materials. We consider carbon nanoparticles and bombarding molecules of helium, hydrogen, and methane.
