Multiplexed thermal desorption spectroscopy was used to study the influence of preadsorbed and postadsorbed deuterium on a methanol monolayer on Pd(111). In particular, the effect of atomic deuterium exposure on the reaction products was examined in detail. Preadsorbed deuterium hinders the formation of chemisorbed methanol and favors physisorption of methanol. This leads to a strong reduction ...

A method to measure the deuterium concentration in basic solutions, using Attenuated Total Reflection Fourier Transformed Infrared Spectroscopy (ATR-FTIR) is described. Deuterium quantification is based on the O-D bond stretching peak. A calibration curve is drawn, representing the peak intensity versus the deuterium percentage in a neutral solution. No calibration curve can be obtained with ba...

Parasitic third harmonic absorption by deuterium in electron current drive scenarios is studied with the newly developed SELFO code calculating self-consistently the wave field and the deuterium distribution function including finite orbit widths and RF induced transport. Self-consistent calculations in toroidal geometry are obtained by iteratively calculating the ion distribution function with...

The strong-interaction shift πD 1s and broadening Γ πD 1s 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 pionic hydrogen. The hadronic broade...

The cover image is based on the Research Article A new deuterium-labeled compound [2,3,4,6,6’-2H5]-D-glucose for deuterium magnetic resonance metabolic imaging by Chao Zou et al., https://doi.org/10.1002/nbm.4890.

Among all isotopes those which would be expected to show the greatest differences from the original element are the isotopes of hydrogen. The addition of one or two protons to a relatively large atom is an insignificant change in comparison with that undergone by the transformation of hydrogen to its nearest isotope, deuterium, for here the extra proton practically doubles the mass. In fact deu...

Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form

Abstract A middle-sensitivity scintillating fiber detector (hereafter middle Sci-Fi detector) that works at a deuterium-tritium neutron flux of ~10 5 -10 7 cm −2 s −1 was utilized to measure secondary emission rates with high temporal resolution total rate 10 13 15 n/s, where strong magnetohydrodynamic (MHD) instabilities were observed in the large helical device deuterium plasma experiments. T...

Hydrous pyrolysis experiments conducted on Messel shale with D2O demonstrated that a large amount of deuterium becomes incorporated into the hydrocarbons generated from the shale kerogen. In order to understand the pathway of deuterium (and protium) exchange and the role of water during hydrous pyrolysis, we conducted a series of experiments using aliphatic compounds (1,13-tetradecadiene, 1-hex...

It was confirmed that nanometer-sized metal powder (atom clusters or simply clusters) can absorb an extremely large amount of deuterium/hydrogen atoms more than 300% against the number density of host metal. Within such clusters, the bonding potential widely changes from the center region to peripheral ones, so that the zig-zag atom-chains are always formed dynamically around the average positi...
