Hydrogen isotope population near dislocations in zirconium from molecular dynamics [PDF]

open access: yesHeliyon
Performance of zirconium tritides used for hydrogen isotope storage is significantly changed under reactor environments. This can be attributed to the formation of various radiation-induced dislocations.

Hydrogen isotope effect on self-organized electron internal transport barrier criticality and role of radial electric field in toroidal plasmas [PDF]

open access: yesScientific Reports, 2022
Self-organized structure formation in magnetically confined plasmas is one of the most attractive subjects in modern experimental physics. Nonequilibrium media are known to often exhibit phenomena that cannot be predicted by superposition of linear ...

Heavy hydrogen in the stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 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.

Photoluminescence Induced in Mineral Oil by Ionizing Radiation

open access: yesLubricants, 2023
We have studied photoluminescence (PL) properties of vacuum pump mineral oil as a function of the type and intensity of ionizing radiation exposure. The mineral oil has a simple aliphatic structure, which possesses no chromophore in the traditional sense.

Molecular dynamics simulations of hydrogen isotope exchange in tungsten vacancies

open access: yesNuclear Materials and Energy, 2021
Solute hydrogen can cause many damaging processes in the lattices of metals, such as deformation of the material, which can take place in large scales through blistering and embrittlement.

An Improved Cr-EA-IRMS Method for the Effective Determination of the Hydrogen Isotopes in Coal Samples

open access: yesFrontiers in Chemistry, 2022
Hydrogen isotope analysis of coal is an important tool in the geochemical analysis of coal. The traditional method of hydrogen isotope analysis of coal requires the oxidation of organic matter bound hydrogen in coal to water by an oxidizing agent and ...

Three-Dimensional Numerical Modeling of a Low-Temperature Sabatier Reactor for a Tandem System of CO2 Methanation and Polymer Electrolyte Membrane Water Electrolysis

open access: yesElectrochemistry, 2022
The Sabatier reaction, which converts CO2 and H2 into CH4 and H2O (methanation), is an attractive way to produce a hydrogen carrier for renewable energy and CO2 recycling.

A Spectroscopic Overview of Intramolecular Hydrogen Bonds of NH…O,S,N Type

open access: yesMolecules, 2021
Intramolecular NH…O,S,N interactions in non-tautomeric systems are reviewed in a broad range of compounds covering a variety of NH donors and hydrogen bond acceptors. 1H chemical shifts of NH donors are good tools to study intramolecular hydrogen bonding.

Global modelling of H2 mixing ratios and isotopic compositions with the TM5 model [PDF]

open access: yes, 2011
The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their isotopic composition, into the global chemistry ...

Reproducible measurements of the δ2H composition of non-exchangeable hydrogen in complex organic materials using the UniPrep2 online static vapour equilibration and sample drying system

open access: yesMethodsX, 2023
Non-exchangeable hydrogen-isotope (δ2Hn) measurements of complex organic samples are used in forensics to determine sample authenticity, traceability, and provenance.
