Elucidation of Diffusivity of Hydrogen Isotopes in Flexible MOFs by Quasi‐Elastic Neutron Scattering
Advances in Materials, 2021Kinetic‐quantum‐sieving‐assisted H2:D2 separation in flexible porous materials is more effective than the currently used energy‐intensive cryogenic distillation and girdle‐sulfide processes for isotope separation. It is believed that material flexibility

Detection of hydrogen isotopes in Zircaloy-4 via femtosecond LIBS
, 2021The analysis of hydrogen isotopes (1H, 2H, and 3H) is crucial to several applications, including nuclear forensics and safeguards, characterization of nuclear fission and fusion reactor materials, geochemistry, and space exploration.

Dynamic metal-organic frameworks for the separation of hydrogen isotopes.
Dalton Transactions, 2020Reversible structural transformation upon exposure to external stimuli can lead to breathing effect or gate-opening phenomena for dynamic metal-organic frameworks (MOFs), which endow them with excellent gas separation performance.

Journal of Chemical Physics, 2018
It has been recently shown that in the presence of an applied voltage, hydrogen and deuterium nuclei can be separated from one another using graphene membranes as a nuclear sieve, resulting in a 10-fold enhancement in the concentration of the lighter ...

Hydrogen isotope cell and its application to hydrogen isotope sensing
Solid State Ionics, 2000Abstract The EMFs of hydrogen isotope cells with H 2 –D 2 gas mixtures against H 2 and D 2 reference gases were measured at 700°C using CaZr 0.90 In 0.10 O 3− α as a proton-conducting solid electrolyte. Steady electromotive forces (EMFs) with quick response were obtained. The EMFs were almost linear functions of the gas composition of the H 2 –D

Hydrogen and oxygen isotope values in hydrogen peroxide
Rapid Communications in Mass Spectrometry, 2011Hydrogen peroxide (H 2 O 2 ) is a widely used oxidizer with many commercial applications; unfortunately, it also has terrorist‐related uses. We analyzed 97 hydrogen peroxide solutions representing four grades purchased across the United States and in ...

Simultaneous determination of stable carbon, oxygen, and hydrogen isotopes in cellulose.
Analytical Chemistry, 2015A technological development is described through which the stable carbon-, oxygen-, and nonexchangeable hydrogen-isotopic ratios (δ(13)C, δ(18)O, δ(2)H) are determined on a single carbohydrate (cellulose) sample with precision equivalent to conventional ...

The secondary hydrogen isotope effect
The International Journal of Applied Radiation and Isotopes, 1960Abstract Secondary isotope effects are reviewed with particular regard to their interpretation within a consistent scheme. It appears that adherence to formal considerations of vibrational frequency shifts is inadequate for the interpretation of many experimental results, and that these may be more fruitfully discussed in terms of “electronic ...
