Heavy hydrogen in the stratosphere [PDF]
, 2003 We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

Deuterium retention in deposited W layer exposed to EAST deuterium plasma
Nuclear 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 ...

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

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