High-pressure studies of the TiCr1.8-H2 system Statistical thermodynamics above the critical temperature
TL;DR: In this article, partial molal enthalpies and entropies of formation were evaluated as a function of hydrogen composition and the experimental isotherms were compared to calculated expressions derived by a rigid-metal sublattice statistical thermodynamics model.

Thermodynamic characterization and statistical thermodynamics of the TiCrMn–H2(D2) system
TL;DR: In this article, the pressure composition (p-c) isotherms of the TiCrMn-H2(D2) system were measured over a wide temperature and pressure range (up to 1000 atm H2/D2).

A theoretical study of the surface diffusion of large molecules. I. n‐alkane‐type chains on W(100)
D. Cohen,Yehuda Zeiri +1 more
TL;DR: In this article, the surface diffusion of model n−alkane-type chains adsorbed on a W(100) surface were simulated using molecular dynamics calculations where the thermal motion of the surface atoms was introduced via the generalized Langevin method.

Model calculations for hydride nucleation on oxide-coated metallic surfaces: surface- and diffusion-related parameters
TL;DR: In this article, a detailed analysis of surface-related parameters and diffusion parameter effects is presented to account for the qualitative trends observed in the initial nucleation and growth stages of some metal-hydrogen reactions.

Molecular dynamics study of the surface diffusion of n-alkane like adsorbates: II. Role of chain stiffness
D. Cohen,Yehuda Zeiri +1 more
TL;DR: In this paper, molecular dynamics calculations were utilized to simulate the surface diffusion of chain like adsorbates and the main goal of these calculations was to study the role of chain rigidity and its influence on the details of surface diffusion mechanism of such adorbates.
