Multi-functional code for hydrogen isotopes transport analyses: verification & validation against fusion-relevant applications

Nuclear Fusion
The management of hydrogen isotopes within a fusion reactor remains a key design issue, with many constraints concerning tritium. The fusion power plant should be self-sufficient with respect to its fuel, while the contamination of components and the ...

Hydrogen isotope MicroChemLab FY15.

, 2015
We have developed a new method to measure the composition of gaseous mixtures of any two hydrogen isotopes, as well as an inert gas component. When tritium is one of those hydrogen isotopes, there is usually some helium present, because the tritium decays to form helium at a rate of about 1% every 2 months.

Hydrogen Isotope Labeling of Pharmaceuticals via Dual Hydrogen Isotope Exchange Pathways

Isotopic labeling is a powerful technique extensively used in the pharmaceutical industry. By tracking isotope-labeled molecules, researchers gain unique and invaluable insights 20 into the pharmacokinetics and pharmacodynamics of new drug candidates. Hydrogen isotope labeling is particularly important as hydrogen is ubiquitous in organic molecules in ...

Optimization of the LIBS Technique in Air, He, and Ar at Atmospheric Pressure for Hydrogen Isotope Detection on Tungsten Coatings

Journal of Nuclear Engineering
In current and future fusion devices, detecting hydrogen isotopes, particularly tritium and deuterium, implanted or redeposited on the surface of Plasma-Facing Components (PFCs) will be increasingly important to ensure safe machine operations.

Isotope engineering achieved by local coordination design in Ti-Pd co-doped ZrCo-based alloys

Nature Communications
Deuterium/Tritium (D/T) handling in defined proportions are pivotal to maintain steady-state operation for fusion reactors. However, the hydrogen isotope effect in metal-hydrogen systems always disturbs precise D/T ratio control.
