Deuterium retention in deposited W layer exposed to EAST deuterium plasma

open access: yesNuclear Materials and Energy, 2017
The deposited W layers formed on the W plate by hydrogen plasma sputtering were exposed to deuterium plasma in EAST together with bare W plate. In TDS measurement, the deuterium release was clearly observed from the deposited W layer in addition to the ...

Microstructure change and deuterium permeation behavior of ceramic-metal multi-layer coatings after immersion in liquid lithium-lead alloy

open access: yesNuclear Materials and Energy, 2018
For the establishment of liquid tritium breeding concepts, static lithium-lead corrosion tests for single-layer erbium oxide coatings and erbium oxide-metal multi-layer coatings were carried out, followed by deuterium permeation measurements.

Visible-light mediated catalytic asymmetric radical deuteration at non-benzylic positions

open access: yesNature Communications, 2022
Catalytic asymmetric deuterations rely largely on two-electron reaction manifolds and are mostly limited to benzylic positions. Here, a metal-free platform using peptide- or sugar-derived chiral thiols and deuterium oxide allows for asymmetric open-shell

Crystallization and deuterium permeation behaviors of yttrium oxide coating prepared by metal organic decomposition

open access: yesNuclear Materials and Energy, 2016
Yttrium oxide coatings were fabricated on reduced activation ferritic/martensitic steels by metal organic decomposition with a dip-coating technique, and their deuterium permeation behaviors were investigated.

Rapid, regioselective deuteration of dimethyl-2,2′-bipyridines via microwave-assistance† [PDF]

open access: yesRSC Advances, 2014
Isotopically pure [D6]-dimethyl-2,2′-bipyridine derivatives were selectively and rapidly formed using microwave-assisted regioselective deuteration of the methyl moieties of the parent bipyridine in a deuterium oxide solution.
