Cosmic Deuterium

open access: yesNuclear Physics B - Proceedings Supplements, 2000
International audienceThe knowledge of the primordial deuterium to hydrogen ratio provides one of the most reliable tests of the early Universe nucleosynthesis models and a direct estimate of the cosmic baryon density. Evaluations have been traditionally

deuterium

open access: yes, 2009
The ponderomotive force, exerted upon all dielectric liquids by a non-uniform electric field, can be used for the remote, voltage-controlled manipulation of 10 to 100 µL volumes of cryogenic liquids. This liquid dielectrophoretic (DEP) effect, imposed by

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

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

Effects of hydrogen plasma treatment on the electronic, optical, mechanical and chemical properties of Mo, Rh, Au, HOPG and Graphene [PDF]

open access: yes, 2013
Interaction of ionic and atomic species of hydrogen isotopes (protium, deuterium and tritium) with transition metals and carbon materials is an important subject of research in the condensed matter physics and material science fields.

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

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

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

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.

Analysis of precipitation and recharge of aquifers in Tota and Ibagué (Colombia) from stable isotopes (18O and 2H)

open access: yesRevista Facultad de Ingeniería, 2018
Identifying the hydraulic connection between the area of recharge and the area of discharge in aquifers is only possible by using tracers; the 18O and 2H isotopes have proven to be good tracers to determine such hydraulic connection.
