CO Removal from Hydrogen Stream through Methanation on Ru/C Catalysts Doped with Lanthanum and Barium

open access: yesHydrogen, 2023
The influence of the lanthanum and barium addition on the physicochemical properties and catalytic behavior of the Ru/C catalyst for CO methanation was investigated. The catalyst was doped with La or with La plus Ba.

Mechano-chemical Synthesis of NaAlH4: Optimization of Reaction Conditions

open access: yesMATEC Web of Conferences, 2016
NaAlH4 was mechano-chemically synthesized with high energy ball-milling method. The effect of synthesis conditions such as milling time, H2 pressure, chloride catalysts, and solvents was investigated to enhance the synthesis of NaAlH4. Among the chloride

Performance of Hydrogen Storage Tanks of Type IV in a Fire: Effect of the State of Charge

open access: yesHydrogen, 2021
The use of hydrogen storage tanks at 100% of nominal working pressure (NWP) is expected only after refuelling. Driving between refuellings is characterised by the state of charge SoC

Hydrogen bubble nucleation by self-clustering: Density Functional Theory and statistical models studies using tungsten as a model system [PDF]

open access: yesJie Hou et al 2018 Nucl. Fusion 58 096021, 2017
Low-energy hydrogen irradiation is known to induce bubble formation in tungsten, while its atomistic mechanisms remain little understood. Using first-principles calculations and statistical models, we studied the self-clustering behavior of hydrogen in tungsten.
