Physisorption of molecular oxygen on single-wall carbon nanotube bundles and graphite

open access: yes, 2002
We present a study on the kinetics of oxygen adsorption and desorption from single-wall carbon nanotube (SWNT) and highly oriented pyrolytic graphite (HOPG) samples. Thermal desorption spectra for SWNT samples show a broad desorption feature peaked at 62

Structure of an inert layer of 4He adsorbed on mesoporous silica [PDF]

open access: yes, 2019
We have performed the measurements of the vapor pressure and heat capacity for inert layer 4He adsorbed on a mesoporous silica. The heat capacity was found to exhibit a Schottky peak, indicating the excitation of the localized solid to fluid. We analyzed

Influence of temperature on sorption process in hemp concrete

open access: yes, 2016
International audienceHemp concrete is a bio-based material which is currently undergoing a growing development. Its hygrothermal behaviour highly depends on the evolution of the moisture content which has a significant influence on heat and moisture ...

Gas adsorption in active carbons and the slit-pore model 1 : pure gas adsorption [PDF]

open access: yes, 2005
We describe procedures based on the polydisperse independent ideal slit-pore model, Monte Carlo simulation and density functional theory (a 'slab-DFT') for predicting gas adsorption and adsorption heats in active carbons.A novel feature of this work is ...

Molecular Simulation of Hydrogen Storage in Ion-Exchanged X Zeolites

open access: yesAdvances in Materials Science and Engineering, 2014
Grand Canonical Monte Carlo (GCMC) method was employed to simulate the adsorption properties of molecular hydrogen on ion-exchanged X zeolites at 100–293 K and pressures up to 10 MPa in this paper.

Combining large-scale screening and machine learning to predict the metal-organic frameworks for organosulfurs removal from high-sour natural gas

open access: yesAPL Materials, 2019
High-sour natural gas usually contains organosulfurs besides H2S, the majority of which exist in the form of mercaptans. These impurities of organosulfurs are required to be removed efficiently and economically for commercial application and the ...
