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 …

Einfluss der Bondcoatzusammensetzung und Herstellungsparameter auf die Lebensdauer von Wärmedämmschichten bei zyklischer Temperaturbelastung
… vapour-containing and reducing, water vapour/hydrogen-atmospheres, as may prevail in power generation systems with CO2 separation, on the oxidation behaviour of MCrAlY alloys was investigated. In water vapour containing atmospheres the hydrogen increases the weight gain by increasing the …

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 …
