The interaction of atoms and molecules with nanocapsules and hollow nanowires

Abstract

Nanoporous membranes are widely used in various fields, such as gas separation, water purification, catalytic processes, and the use of batteries in electrodes. Nowadays, hollow carbon spheres or nanowires are attracting attention of researchers and experimenters due to high adjustability of their mechanical and chemical properties. This makes it possible, among other things, to more accurately adjust permeability of membranes created from this material for various atoms and molecules, which ensures a good degree of gas separation. The mathematical simulation of gas separation via nanocapsule and hollow nanowire porous membrane is performed. Research has shown that such membranes are able to separate He/$$\text{CH}_4$$ CH 4 /$$\text{H}_2$$ H 2 /$$\text{N}_2$$ N 2 gas mixtures.

“…Permeability is a key property to describe the kinetics of mass transport of a substance through a membrane. It is highly relevant in various research and application fields, such as membrane technology for chemical separation [1][2][3][4] and passive permeation of substances through the cell membrane. 5,6 In biology, permeation through the cell membrane is a vital process that is relevant for drug delivery 5,6 and the regulation of cell death and proliferation.…”
