Journal ArticleDOI
The Lennard-Jones equation of state revisited
TL;DR: In this paper, a modified Benedict-Webb-Rubin (MBWR) equation of state for the Lennard-Jones (LJ) fluid is presented and compared with the simulation data of this work, and previously published Gibbs ensemble data.
Journal ArticleDOI
Rapid transport of gases in carbon nanotubes.
TL;DR: Atomistic simulations for both self- and transport diffusivities of light gases in carbon nanotubes and in two zeolites with comparable pore sizes show exceptionally high transport rates in nanotube membranes.
Journal ArticleDOI
Microporous metal organic materials: promising candidates as sorbents for hydrogen storage.
Long Pan,Michelle B. Sander,Xiaoying Huang,Jing Li,Milton R. Smith,Edward Bittner,Bradley Bockrath,J. Karl Johnson +7 more
TL;DR: A novel MMOM structure and its room-temperature hydrogen adsorption properties are reported and it is reported that these materials possess physical characteristics similar to those of single-walled carbon nanotubes but also exhibit a number of improved features.
Journal ArticleDOI
Molecular simulation of hydrogen adsorption in single-walled carbon nanotubes and idealized carbon slit pores
Qinyu Wang,J. Karl Johnson +1 more
TL;DR: In this paper, the adsorption of hydrogen gas into single-walled carbon nanotubes (SWNTs) and idealized carbon slit pores is studied by computer simulation.
Journal ArticleDOI
Adsorption of Gases in Metal Organic Materials: Comparison of Simulations and Experiments
TL;DR: The volume available in a given sorbent at a specified adsorption energy (density of states) and how this density of states can be used to assess the effectiveness of a sorbent material for hydrogen storage are calculated.
