Influence of the presence of deuterium on displacement damage in tungsten

open access: yesNuclear Materials and Energy, 2018
The influence of the presence of deuterium on displacement damage in tungsten is studied by implanting 20 MeV tungsten ions into displacement-damaged tungsten already containing 1.7 at.% deuterium.

The biological impact of deuterium and therapeutic potential of deuterium-depleted water

open access: yesFrontiers in Pharmacology
Since its discovery by Harold Urey in 1932, deuterium has attracted increased amounts of attention from the scientific community, with many previous works aimed to uncover its biological effects on living organisms.

Characterization of a deuterium–deuterium plasma fusion neutron generator [PDF]

open access: yesNuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2018
We characterize the neutron output of a deuterium-deuterium plasma fusion neutron generator, model 35-DD-W-S, manufactured by NSD/Gradel-Fusion. The measured energy spectrum is found to be dominated by neutron peaks at 2.2 MeV and 2.7 MeV. A detailed GEANT4 simulation accurately reproduces the measured energy spectrum and confirms our understanding of ...

Cp*Co-catalyzed directed hydrogen isotope exchange with substrate-dependent deuterium source [PDF]

open access: yes, 2023
Despite the growing interest in directed Hydrogen Isotope Exchange (HIE) reactions, the existing synthetic protocols mainly rely on noble metals and the choice of the deuterium source remains unclear. Herein, we developed different reaction conditions to

To Divide or Not to Divide? How Deuterium Affects Growth and Division of Chlamydomonas reinhardtii

open access: yesBiomolecules, 2021
Extensive in vivo replacement of hydrogen by deuterium, a stable isotope of hydrogen, induces a distinct stress response, reduces cell growth and impairs cell division in various organisms.

Kinetics of Hydrogen-to-Deuterium Exchange Compared to Deuterium-to-Hydrogen Exchange in Hydrogen Bonds within a Model Peroxo Complex [PDF]

open access: yes, 2023
Hydrogen and deuterium atom exchange kinetics in covalent chemical bonds help establish structure, and function of individual molecules. On the other hand, hydrogen bonding is vital to collective properties of many molecules in assemblage.

Pionic deuterium [PDF]

open access: yesHyperfine Interactions, 2009
The strong interaction shift $ε$ and broadening Γ in pionic deuterium have been determined in a high statistics study of the πD(3p - 1s) X-ray transition using a high-resolution crystal spectrometer. The pionic deuterium shift will provide constraints for the pion-nucleon isospin scattering lengths extracted from measurements of shift and broadening in

To shred roughly or to grind? On the methods of sample preparation of the keratinous material for stable hydrogen isotope analysis

open access: yesТрансформация экосистем, 2020
Hydrogen stable isotope measurement in keratin samples (hair, feathers, etc.) is one of the very popular, but rather complex tasks of isotope ratio mass spectrometry.

Deuterium- and Electron-Shuttling Catalysis for Deoxygenative Deuteration of Alcohols

open access: yes, 2023
A practical and precise method for visible-light-promoted deoxygenative deuteration of common aliphatic alcohols using D2O as the deuterium source is reported.
