Isotopic and spin selectivity of H_2 adsorbed in bundles of carbon nanotubes

, 2002
Due to its large surface area and strongly attractive potential, a bundle of carbon nanotubes is an ideal substrate material for gas storage. In addition, adsorption in nanotubes can be exploited in order to separate the components of a mixture.
