Permeation rates of electrolytic hydrogen and deuterium through iron

, 1963
The relative permeation rates of electrolytically discharged hydrogen, deuterium, and mixtures of the two through sheet-iron cathodes were measured, and values for both the separation factor and the combined separation-permeation factor were determined ...

HyPAT: A GUI for high-throughput gas-driven hydrogen permeation data analysis

SoftwareX, 2023
The Hydrogen Permeation Analysis Tool (HyPAT) is a Python-based graphical user interface (GUI) that streamlines data analysis for hydrogen gas-driven permeation experiments to measure the following hydrogen transport properties in materials: permeability,

Enhanced hydrogen-gas permeation through rippled graphene

, 2023
The penetration of atomic hydrogen through defect-free graphene was generally predicted to have a barrier of at least several eV, which is much higher than the 1 eV barrier measured for hydrogen-gas permeation through pristine graphene membranes. Herein,

Permeation and trapping of hydrogen in Eurofer97

Nuclear Materials and Energy, 2021
Diffusion and trapping of hydrogen isotopes in fusion materials need to be fully described in order to evaluate permeation and retention in fusion reactors walls and breeding blankets. Hydrogen gas permeation experiments have been conducted on Eurofer97 with pressures ranging from 101to 105Pa and temperatures between 473 K and 673 K, resulting in ...

Effect of Au addition on hydrogen permeation and the resistance to H2S on Pd-Ag alloy membranes [PDF]

, 2017
In order to make a detailed comparison between Pd-Ag and Pd-Ag-Au membranes according to their H2 permeation properties and sulfide resistance Au was deposited by the electroless plating (ELP) technique onto one half of Pd-Ag membranes.

The Effect of Nickel Plating on Hydrogen Embrittlement of High Strength Steel. [PDF]

, 1992
The microstructure of high strength steel is susceptible to delayed failure caused by the absorption of hydrogen produced either during cathodic charging or electroplating. When 0.8%C and AISI 4340 steel are subjected to constant load testing, a wide
