The existence and properties of gases adsorbed within interstitial channels of nanotube bundles
M. Mercedes Calbi, Flavio Toigo, Milton W. Cole
We analyze the relationship between our group's results and those of three recent papers about gases in interstitial channels within nanotube bundles. In particular, we explain the…
Lattice dilation near a single hydrogen molecule in an interstitial channel within a nanotube bundle
M. Mercedes Calbi, Ari Mizel, Milton W. Cole
We explore the ground state of a single hydrogen molecule within an interstitial channel (IC) of a bundle of carbon nanotubes. A previous (variational) study found that when many m…
Universal anisotropic condensation transition of gases in nanotube bundles
Silvina M. Gatica, M. Mercedes Calbi, Milton W. Cole
Gases adsorbed within bundles of carbon nanotubes (inside of the nanotubes or in the interstitial channels between the tubes) exhibit a variety of phase transitions with the help o…
Bose-Einstein Condensation of Molecular Hydrogen in Nanotube Bundles
Francesco Ancilotto, M. Mercedes Calbi, Silvina M. Gatica +1
We evaluate the effects of heterogeneity on the density of states of H molecules inside interstitial channels within bundles of carbon nanotubes. As temperature (T) falls, the…
Three-body interactions involving clusters and films
Silvina M. Gatica, M. Mercedes Calbi, Milton W. Cole +1
The three body (triple dipole) interaction of Axilrod, Teller and Muto (ATM) contributes 5 to 10 % of the total energy of condensed phases of inert elements. It is shown in this pa…
Peas in a pod: quasi-one-dimensional C60 molecules in a nanotube
M. Mercedes Calbi, Silvina M. Gatica, Milton W. Cole
We evaluate the equation of state of the quasi-one-dimensional (1D) phase of C60 molecules in small carbon nanotubes, nicknamed ``peas in a pod''. The chemical potential and 1D pre…
Retarded and nonretarded van der Waals interactions between a cluster and a second cluster or a conducting surface
M. M. Calbi, S. M. Gatica, D. Velegol +1
In some respects, a cluster consisting of many atoms may be regarded as a single large atom. Knowing the dielectric properties of such a cluster permits one to evaluate the form of…
Ground state and thermal properties of a lattice gas on a cylindrical surface
M. Mercedes Calbi, Silvina M. Gatica, Mary J. Bojan +1
Adsorbed gases within, or outside of, carbon nanotubes may be analyzed with an approximate model of adsorption on lattice sites situated on a cylindrical surface. Using this model,…
Dimensional crossover and quantum effects of gases adsorbed on nanotube bundles
M. Mercedes Calbi, Milton W. Cole
Adsorption properties of several gases (Ne, CH4, Ar, Xe) on the external surface of a carbon nanotube bundle are investigated. Calculations are performed at low coverage and variab…
Phases of Neon, Xenon, and Methane adsorbed on nanotube bundles
M. M. Calbi, S. M. Gatica, M. J. Bojan +1
We explore the behavior of neon, xenon, and methane filmas adsorbed on the external surface of a bundle of carbon nanotubes. The methods used are classical: a ground state calculat…
Condensed phases of gases inside nanotube bundles
M. Mercedes Calbi, Milton W. Cole, Silvina M. Gatica +2
An overview is presented of the various phases predicted to occur when gases are absorbed within a bundle of carbon nanotubes. The behavior may be characterized by an effective dim…
Dilation-induced phases of gases absorbed within a bundle of carbon nanotubes
M. Mercedes Calbi, Flavio Toigo, Milton W. Cole
A study is presented of the effects of gas (especially H2) absorption within the interstitial channels of a bundle of carbon nanotubes. The ground state of the system is determined…
