Kinetics of Hydrogen in Metals Absorption, Desorption, Dissolution, Diffusion, Trapping, and Permeation

Introduction.- Schematics of a hydrogen profile in a metal.- Hydrogen loading.- Methods for hydrogen detection and mapping.- Kinetics of hydrogen in metals dissolution diffusion permeation and trapping.- H profiles on surface and in depth hydrogen mapping and depth profiling.- Diffusion permeation and solution of metal and alloys.- Effect of oxygen and water included in hydrogen as impurities.- Hydrogen permeation barrier.- Hydrogen in oxide.- Hydrogen in carbon materials.- H release from dissolution and accumulated sites detrapping.- Experimental limitation and remaining problems for understanding h kinetics in metals.

Tetsuo Tanabe is a guest professor at Nagoya University. His work involves nuclear materials and fusion engineering, including tritium engineering and science and plasma wall interactions. He also works on hydrogen energy technology and effective energy conversion. He received his Doctor of Engineering from Osaka University, currently known as the University of Osaka, in 1977. He was an associate professor at Osaka University from 1990 to 1994, a professor at Nagoya University from 1995 to 2005 and at Kyushu University from 2005 to 2011; a research professor at Kyushu University from 2012 to 2017; a professor at the Institute for Laser and Plasma Technologies, National Research Nuclear University MEPHI 2015–2021; and a special appointment professor at Osaka City University from 2017 to 2025. He has served in his current position since 2024. He is also a professor emeritus at Nagoya University and Kyushu University.
