Hydrogen in transition metal doped transparent conductive oxide SnO₂
… Carlo methods are used to study the behavior of hydrogen defects in doped-tin oxides. The calculated results indicate that Mo-, W-, Nb-, F-doped SnO2 are the best doped-tin oxides at reducing hydrogen solubility in their matrices. We expect these oxides also to be the best for removing hydrogen …

STUDY OF STRUCTURAL, THERMAL, HYDROGENATION AND COMPOSITIONAL PROPERTIES OF NI-BASED AMORPHOUS MEMBRANES USING EXPERIMENTAL AND COMPUTATIONAL METHODS
Hydrogen is considered as a promising source of energy because of its properties such as abundant availability, high energy conversion efficiency, low-density, solid-state storage potential, and most importantly zero emission from energy conversion devices, such as fuel cell. End product from …

First-principles approach to screening multi-component metal alloys for hydrogen purification membranes
Metal membranes play a vital role in hydrogen purification. Defect-free membranes can exhibit effectively infinite selectivity for hydrogen. Membranes must meet multiple objectives, including providing high fluxes, resistance to poisoning, long operational standards, and be cost effective. Alloys …

Effects of hydrogen in an aluminium-magnesium-silicon alloy during the production of extrusion ingots
Hydrogen causes defects, for which aluminiurn alloy products are rejected. The behaviour of hydrogen in aluminium-magnesium-silicon alloy extrusion ingots, has been studied throughout the course of manufacture from freshly reduced aluminium. It is shown that hydrogen in the liquid metal is produced …

Predicting the equilibria of point defects in zirconium oxide : a route to understand the corrosion and hydrogen pickup of zirconium alloys
… nuclear reactors is compromised by corrosion and hydrogen pickup. The thermodynamics and kinetics of these two processes are governed by the behavior of point defects in the ZrO₂ layer that grows natively on these alloys. In this thesis, we developed a general, broadly applicable framework to …

Investigation effect of external stress on hydrogen solvus in a zircaloy-4 fuel cladding alloy: application of in situ diffraction technique and mesoscale phase-field simulation
… The temperature effect can be modeled using the hydrogen solvus and the temperature-driven hydrogen diffusion (Soret effect). However, while correlating the effect of stress on hydride formation, a disagreement arises between the experimental data and the theoretical model. The theory predicts …
