- This work addresses the physical adsorption of gases in carbon nanotubes. In the confining environment of nanotube bundles, adsorbed atoms exhibit behavior characteristic of 1, 2, and 3 dimensions as a function of thermodynamic parameters, geometry, and microscopic variables.

In the confining environment of nanotube bundles, adsorbed atoms exhibit behavior characteristic of 1, 2, and 3 dimensions as a function of thermodynamic parameters, geometry, and microscopic variables. Many body interactions among quasi-1D phases of gases adsorbed within carbon nanotubes and the corresponding implications for condensation transition are investigated. Theoretical calculations and computer simulations are carried out to determine the dynamics and structure of molecular hydrogen physisorbed within nanotube bundles. Phonons and specific heat of quasi-1D phases of atoms adsorbed on the external surface of a nanotube bundle are studied. From a purely fundamental viewpoint, both classical and quantum particles confined to a cylindrical surface are also explored.esponding implications for condensation transition are investigated.
