Hydrogen isotope cell and its application to hydrogen isotope sensing

Solid State Ionics, 2000
Abstract 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, 2011
Hydrogen 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 ...

The Isotope Effect in Hydrogen-Bonded Systems

International Journal of Modern Physics B, 1998
The giant isotope effect on the ferro- and antiferroelectric transition temperature upon deuteration of hydrogen-bonded systems is well known experimentally since various decades. Yet, theoretically only recently a microscopic understanding of this effect has been achieved which, specifically, took into account the geometry of the O ⋯ H ⋯ O bond.

The secondary hydrogen isotope effect

The International Journal of Applied Radiation and Isotopes, 1960
Abstract 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 ...

MUON CAPTURE IN HYDROGEN ISOTOPES

Nuclear Physics A, 1981
Abstract After a survey of the phenomenology of muonic hydrogen atoms and molecules recent experiments at SIN are discussed, dealing with muonic atoms and molecules in deuterium. These experiments could clarify the longstanding problem of hyperfine populations of muonic deuterium atoms.

Hydrogen Isotope Exchange

Nature, 1956
THERE appears to be some confusion1–3 in the derivation and application of certain relationships featuring the separation factor for hydrogen (H) and deuterium (D) chemical-exchange processes.
