A Simplistic Analytical Model for Hydrogen Surface Coverage Under the Influence of Various Surface-Related Processes and Ion Bombardment

East European Journal of Physics
The paper describes a simple analytical model that allows the calculation of hydrogen surface coverage under the influence of several processes that can co-occur during the ion-beam bombardment/sputter analysis of a sample surface, in particular during ...

Effect of Ion-Exchange Modification on Hydrogen and Carbon Dioxide Adsorption Behaviour of RhoZMOF Material

Adsorption Science & Technology, 2012
Zeolite-like metal-organic frameworks (ZMOFs) can adsorb hydrogen and carbon dioxide because of their negatively charged structures, being able to be ion exchanged with metal cations to further increase the electrostatic field inside the framework ...

Density of neutral interstellar hydrogen at the termination shock from Ulysses pickup ion observations

, 2008
By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination ...
