Deuterium, also known as heavy hydrogen and H-2, is a stable isotope of hydrogen. Its nucleus consists of a proton and a neutron. About 0.0156% of the hydrogen atoms in the Earth's seawater are ...

Stable isotopes are safe, non-radioactive forms of common elements such as carbon, nitrogen and hydrogen that occur naturally in small amounts in the foods and water we consume every day. Because they ...

AFTER the discovery by Urey of the isotope of hydrogen of mass 2 (deuterium) and its concentration by electrolysis, it was natural to examine whether any other stable isotopes of hydrogen, and ...

By analyzing stable isotopes of hydrogen, carbon, and nitrogen in bird feathers, Duxbury has been able to trace Burrowing Owls wintering grounds in southern Texas and central Mexico, ...

The article, “Isotope-dependent site occupation of hydrogen in epitaxial titanium hydride nanofilms,” was published in Nature Communications at DOI: 10.1038/s41467-024-53838-6 .

While deuterium is stable, it’s far lower-powered than tritium, which is much heavier and more massive. Imagine shaking a coffee can with 50 pennies inside versus 50 quarters: the shaking is the ...

Exploiting Diffusion Barrier and Chemical Affinity of Metal–Organic Frameworks for Efficient Hydrogen Isotope Separation. Journal of the American Chemical Society , 2017; 139 (42): 15135 DOI: 10 ...

Studies are already in progress using stable isotopes to characterize and differentiate amongst bird populations using δC-13 and δN-15 values in metabolically active tissues (blood and muscle), but ...

Scientists have developed a novel hydrogen isotope separation system based on a porous metal organic framework (MOF). This MOF system, could efficiently separate and store deuterium inside the pores, ...

The Austedo approval is notable for two reasons: One, it is the first deuterated drug (i.e., a drug containing the stable isotope — deuterium — in place of a hydrogen atom) to be approved by ...
