A comparative study of nitrogen physisorption on different C(sub 70) crystal structures using an ab initio based potential

Article Abstract:

The ab initio based potential was used in Monte Carlo simulations to predict surface adsorption properties of N(sub 2) on five known C(sub 70) structures such as rhombohedral, fcc, ideal hcp, deformed hcp, and monoclinic crystals. The surface area, monolayer capacity, and isosteric heat of adsorption were calculated for various C(sub 70) crystals and found to change appreciably as a result of the shear-induced phase transformation from hcp to rhombohedral lattice.

Properties and structure of nitric acid oxidized single wall carbon nanotube films

Article Abstract:

The properties and structure of nitric acid oxidized single wall carbon nanotube (SWNT) films are studied by preparing single wall carbon nanotube films using aqueous dispersions containing 0, 3, 6, and 10 M nitric acid. The results reveal that the mechanical properties of SWNT film can be significantly improved by nitric acid oxidation.

N2 physisorption on carbon nanotubes: computer simulation and experimental results

Article Abstract:

Monte Carlo simulations, in a wide temperature range, are used to study nitrogen physical adsorption on nanotubes bundles. A hexagonal array is formed when the nanotubes are modeled by grouping them in bundles, and the local adsorption isotherms are calculated.
