Precise deuterium incorporation with controllable deuterated sites and amount is extremely desirable. Here, a facile and efficient electrocatalytic deuterodehalogenation of halides using heavy water (D 2 O) as the deuteration reagent and electrochemical ...

Deuterium fractionations in cometary ices provide important clues to the origin and evolution of comets. Mass spectrometers aboard spaceprobe Giotto revealed the first accurate D/H ratios in the water of Comet 1P/Halley. Ground-based observations of HDO in Comets C/1996 B2 (Hyakutake) and C/1995 O1 (Hale-Bopp), the detection of DCN in Comet Hale-Bopp ...

Burn performance of deuterium-tritium, deuterium-deuterium, and catalyzed deuterium ICF targets
Nuclear Fusion, 1983The University of Illinois hydrodynamic burn code, AFBURN, has been used to model the performance of homogeneous D-T, D2, and catalyzed deuterium ICF targets. Yields and gains are compared for power-producing targets. AFBURN is a one-dimensional, two-temperature, single-fluid hydrodynamic code with non-local fusion product energy deposition.

Motivated by the problem of energy shortage and in view of current efforts to develop clean, renewable energy sources based on fusion, we propose a solar-driven strategy for deuterium evolution. Deuterium is a critical resource for many aspects; however,

Nuclear Physics B - Proceedings Supplements, 2000
The 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 made using D/H estimations in the interstellar medium, extrapolated backwards in time with the use of galactic evolution ...

Contemporary hydrogen deuterium exchange mass spectrometry.
Methods, 2018Hydrogen/deuterium exchange (HDX) mass spectrometry (MS) emerged as a tool for biochemistry and structural biology around 25 years ago. It has since become a key approach for studying protein dynamics, protein-ligand interactions, membrane proteins and ...

Impact of Deuterium Substitution on the Pharmacokinetics of Pharmaceuticals
The Annals of Pharmacotherapy, 2018Objective: Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process.
