Deuterium isotope effect on the dissociation of weak acids in water and deuterium oxide

open access: yesJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1969
The dissociation constants of o-nitroanilinium ion, m-nitroanilinium ion, and 4-chloro-2,6-dinitrophenol in deuterium oxide at 25 °C have been determined by a spectrophotometric method, and an emf method has been used to obtain (pK 1 + pK 2)/2 for citric acid in deuterium oxide.

PRODUCTION OF STERILITY IN MICE BY DEUTERIUM OXIDE [PDF]

open access: yesProceedings 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]

open access: yes, 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]

open access: yes, 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

An In Vivo Stable Isotope Labeling Method to Investigate Individual Matrix Protein Synthesis, Ribosomal Biogenesis, and Cellular Proliferation in Murine Articular Cartilage

open access: yesFunction, 2022
Targeting chondrocyte dynamics is a strategy for slowing osteoarthritis progression during aging. We describe a stable-isotope method using in vivo deuterium oxide labeling and mass spectrometry to measure protein concentration, protein half-life, cell ...

Speed effects in gliding motility assays due to surface passivation, water isotope, and osmotic stress. [PDF]

open access: yes, 2010
The molecular motor kinesin-1, an ATPase, and the substrate it walks along, microtubules, are vital components of eukaryotic cells. Kinesin converts chemical energy to linear motion as its two motor domains step along microtubules in a process similar to

Deuterium plasma exposure of thin oxide films on tungsten - oxygen removal and deuterium uptake

open access: yesNuclear Materials and Energy, 2023
Recently we have shown that thin (33 to 55 nm) oxide films on tungsten (W) prevent deuterium (D) uptake from a low-temperature plasma (5 eV/D; 370 K; 1.4 × 1024 D/m2) into metallic W.

The effect of γ-ray irradiation on deuterium permeation through reduced activation ferritic steel and erbium oxide coating

open access: yesNuclear Materials and Energy, 2018
Deuterium permeation through a fusion-relevant ferritic steel F82H with and without erbium oxide coatings under γ-ray irradiation has been investigated in a temperature range from 300 to 700 °C. The deuterium permeation flux through F82H sample increased

Production of Sterility in Mice by Deuterium Oxide [PDF]

open access: yesScience, 1958
Sterility was induced in both male and female mice following the substitution of D/sub 2/O for a part of the drinking water. Doses of 5 to 30% deuterium oxide were administered. C/sub 57/ and Swiss mice were used and both strain and sex differences in response to D/sub 2/O were noted.
