The general equation of supercritical gas adsorption isotherm

Article Abstract:

A new equation of the absolute adsorption isotherm for supercritical gas is proposed and the effectiveness of this equation using density functional theory (DFT) is examined. It concluded that the newly proposed adsorption equation could give essentially important information on supercritical gas adsorption even in the case of the high-pressure adsorption isotherm covering the insufficient pressure range.

Palladium Nanoclusters deposited on single-walled carbon Nanohorns

Article Abstract:

A direct route for deposition of palladium nanoclusters on single-walled carbon nanohorns (SWNHs) in a one step reaction involving chemical reduction of metal ions in the presence of a polymer-stabilizer is discussed. This provides small palladium clusters with an average diameter of ~ 2.3 nm robustly attached to the nanotubular carbon.

Single-walled nanostructures carbon for methane storage

Article Abstract:

The open single-walled carbon nanostructures (SWNHs) are compressed repeatedly at 50MPa to generate a noncarbon material of high bulk density. The observations reveal a significant distortion in the structure of the compressed SWNHs that exhibited a high methane storage capacity.
