Hydrogen isotopic characteristic of hydrocarbon gas pyrolyzed by herbaceous swamp peat in hydrous and anhydrous thermal simulation experiments

Journal of Natural Gas Geoscience, 2018
In order to understand the influence of diagenetic water medium on hydrogen isotope of thermogenic coalbed gas, the hydrous and anhydrous pyrolytic simulation experiments have been carried out on herbaceous peat.

Heavy hydrogen in the stratosphere [PDF]

Atmospheric 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.

Experimental Determination of Primary and Secondary Deuterium Isotope Effects in the FeI-Mediated CH/CC Bond Activation of [Fe(4-Heptanone)]⊕ Complexes in the Gas Phase

CHIMIA, 1989
The gas-phase behaviour of [Fe(4-heptanone)]⊕ is in several aspects quite distinct from that of other Fe⊕ complexes as far as kinetic details of the individual steps of CH/CC bond activation are concerned.

Modeling of hydrogen isotope effect on divertor detachment in EAST

Nuclear Fusion
The two-dimensional edge plasma code SOLPS-ITER have been used to study the hydrogen isotope effect on the divertor detachment onset for hydrogen (H), deuterium (D), and tritium (T) based on EAST plasma conditions.

Deuterium retention behavior in simultaneously He+–D2+ implanted tungsten

Nuclear Materials and Energy, 2018
Poly-crystalline tungsten (W) samples were simultaneously irradiated with Helium (He) and Deuterium (D) ions using the triple-ion implantation device. He effect on D retention and transportation was studied using different combination of ion energies and

Links between environmental conditions and pedogenic phyllosilicates in Podzols in the Tatra Mountains (Poland) – II. Hydrogen and oxygen isotope compositions

Geoderma
Stable isotope compositions of pedogenic clay minerals can be used as a paleoclimatic proxy. The underlying fundamental assumption is that pedogenic clays are formed in isotope equilibrium with the environment, which is well-documented for hot and humid ...

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.

Separation of Hydrogen Isotopes by Metal-Organic Framework Quantum Sieving Effect

He huaxue yu fangshe huaxue
Due to the similar physical and chemical properties of hydrogen isotopes, the separation of high-purity hydrogen isotopes has become one of the major problems in modern separation technology. The realization of high-purity hydrogen isotope separation can

Effect of Water‐Rock Ratio on the Stable Isotope Record of Fluid‐Rock‐Deformation Interactions in Detachment Shear Zone

Geochemistry, Geophysics, Geosystems
Oxygen and hydrogen stable isotope analyses of quartz and muscovite veins from the footwall of the Raft River detachment shear zone (Utah) provide insight into the hydrology and fluid‐rock interactions during ductile deformation.

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.
