Retention of deuterium in beryllium: A combined investigation using TDS, ERDA and EBS
Nuclear Materials and Energy, 2022 We have studied the retention of deuterium in beryllium, implanted with an energy of 500 eV/D, using a combination of thermal desorption spectroscopy, elastic recoil detection analysis and elastic backscattering spectroscopy.

Facile and general electrochemical deuteration of unactivated alkyl halides
Nature Communications, 2022 Deuterium-labelled compounds are useful for mechanistic studies and pharmaceutical science, but syntheses are not trivial. Here, the authors report deuteration of unactivated alkyl (pseudo)halides driven by electrochemical force, using deuterium oxide as

Rapid antimicrobial susceptibility testing from positive blood cultures based on Stimulated Raman Scattering Imaging analysis [PDF]
E3S Web of Conferences, 2021 The existing identification (ID) and antimicrobial susceptibility testing (AST) method requires at least two to three days to detect blood infection, and a fast and accurate detection method is very necessary for sepsis patients or Intensive Care Unit ...

PRODUCTION OF STERILITY IN MICE BY DEUTERIUM OXIDE [PDF]
Proceedings of the National Academy of Sciences, 1959 Some of the conditions required to produce sterility in male mice by D/ sub 2/O were investigated. Sterility can be produced in C/sub 57/ male mice by substitution of 30% D/sub 2/O for normal water in the drinking water for two weeks. The mice become sterile four weeks aftcr the initial treatment with D/sub 2/O, and in this experiment two weeks after ...

Effect of deuterium on the circadian period and metabolism in wild-type and tau mutant Syrian hamsters [PDF]
, 2000 Homozygous tau mutant Syrian hamsters (tau-/-) have a free-running circadian period (τ) around 20 h and a proportionally higher metabolic rate compared with wild-type hamsters (tau+/+) with a period of circa 24 h.

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 ...
