Permeation of Hydrogen in Palladium

Materials Transactions, JIM, 1993
Experimental studies on the permeation of hydrogen in a palladium plate 1-2×10 -4 m in thickness were carried out at a constant temperature under the application of a constant hydrogen pressure in the respective ranges from 261 to 191 K and from 66.5 to 2660 Pa. Hydrogen permeabilities obtained in the permeation experiment are expressed by the formula

Evaluation of hydrogen permeation rate through zirconium pipe

Nuclear Materials and Energy, 2018
To launch a fusion reactor stably, it is necessary to prepare sufficient amount of tritium by an external tritium source. Tritium production using nuclear reactions by neutron and Li in a high temperature gas-cooled reactor (HTGR) is an attractive method.

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 ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...
