Mass spectrometric measurement of hydrogen isotope fractionation for the reactions of chloromethane with OH and Cl [PDF]

Atmospheric Chemistry and Physics, 2018
Chloromethane (CH3Cl) is an important provider of chlorine to the stratosphere but detailed knowledge of its budget is missing. Stable isotope analysis is a potentially powerful tool to constrain CH3Cl flux estimates.

Isotope Effects on Chemical Shifts in the Study of Intramolecular Hydrogen Bonds

Molecules, 2015
The paper deals with the use of isotope effects on chemical shifts in characterizing intramolecular hydrogen bonds. Both so-called resonance-assisted (RAHB) and non-RAHB systems are treated. The importance of RAHB will be discussed.

Temperature dependence of hydrogen isotope effect in LaNi5-H(D) system

Nuclear Analysis, 2023
To study inverse effect of hydrogen isotopes in LaNi5 for hydrogen isotope separation at ambient temperature, temperature dependence of hydrogen isotope effect in LaNi5－H(D) system was investigated in the temperature range -70 °C to 3 °C.

Isotopes in hydrology and hydrogeology [PDF]

, 2019
The structure, status, and processes of the groundwater system, which can only be acquired through scientific research efforts, are critical aspects of water resource management. Isotope hydrology and hydrogeology is a genuinely interdisciplinary science.

Bifunctional catalytic activity of anion-doped LaSrCoO4 for oxygen reduction and evolution reactions

Royal Society Open Science
Here, we synthesized Co-based, anion-incorporated‍ ‌R‌u‌d‌d‌l‌e‌s­d‌e‌n‌–‌Popper perovskite electrocatalysts (LaSrCoO4−x X y ) and compared their catalytic performances in the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Ab initio simulations of the kinetic properties of the hydrogen monomer on graphene

, 2010
The understanding of the kinetic properties of hydrogen (isotopes) adatoms on graphene is important in many fields. The kinetic properties of hydrogen-isotope (H, D and T) monomers were simulated using a composite method consisting of density functional ...

D/H ratios of the inner Solar System [PDF]

, 2017
The original hydrogen isotope (D/H) ratios of different planetary bodies may indicate where each body formed in the Solar System. However, geological and atmospheric processes can alter these ratios through time.
