Kinetics of the Lattice Response to Hydrogen Absorption in Thin Pd and CoPd Films [PDF]

Molecules, 2020
Hydrogen can penetrate reversibly a number of metals, occupy the interstitial sites and cause large expansion of the crystal lattice. The question discussed here is whether the kinetics of the structural response matches hydrogen absorption. We show that

2-step reaction kinetics for hydrogen absorption into bulk material via dissociative adsorption on the surface [PDF]

Scientific Reports, 2021
We have demonstrated that the process of hydrogen absorption into a solid experimentally follows a Langmuir-type (hyperbolic) function instead of Sieverts law. This can be explained by independent two theories.

Evaluation of Hydrogen Gettering Rates Correlated to Surface Composition and Texture of Nickel-Plated Zircaloy Getters of Different Heat Treatment Procedures

Molecules, 2023
Coatings of metal specimens are known to have an impact on hydrogen gettering (hydrogen absorption). The coating can have one or more functions, such as enhancing gettering, preventing gettering and/or preventing oxidation of the metal substrate.

Hydrogen Insertion into Complex-Phase High-Strength Steel during Atmospheric Corrosion at Low Relative Humidity

Metals, 2022
Atmospheric corrosion is one of the major sources of hydrogen in a high-strength-steel product in service. Even low concentrations of absorbed hydrogen can cause a hydrogen embrittlement-related material degradation.

Kinetic Mechanism of Hydrogen Absorption of AA6111 Alloys Melt

Metals, 2023
The kinetic mechanism of hydrogen absorption of the AA6111 alloy melt in different melting environments, and the in-situ real-time observation of the oxide film structure during the hydrogen absorption process were studied.

Heavy-Fermion Properties of Yb₂Pd₂SnH_≈2

Inorganics, 2023
A hydride of Yb2Pd2Sn could be synthesized with approximately 2 H atoms per f.u. The hydrogenation leads to a volume expansion while preserving the tetragonal symmetry (P4/mbm).

Kinetics of hydrogen absorption and desorption in LaNi5-xAlx slurries [PDF]

, 1993
The kinetics of hydrogen absorption and desorption in LaNi4.8Al0.2,LaNi4.9Al0.1 and LaNi5, suspended in cyclohexane and LaNi5 in ethanol have been investigated. The absorption process can be described in terms of mass transfer and reaction resistances in
