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 ...

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 .

Teeth from sharks and rays can be used to study their diet, but one of the biggest challenges in shark science is collecting samples from rare or protected species.

Several hydrogen isotopes exist, and deuterium is one of the most stable. It contains one neutron and one proton, making it one neutron heavier than hydrogen.

Scientists who use the IRMS most often examine isotopes of hydrogen, carbon, oxygen, and nitrogen. The samples can be from plants, microbes, soil, or fossil material. They can be solids, liquids ...

Deuterium, a stable isotope of hydrogen, plays a critical role in enhancing the durability and luminous efficiency of semiconductors and display devices, as well as serving as a fusion fuel in ...

Understanding whether lakes are fed predominantly by groundwater or rainwater is critical to managing our water resources in ...

A stable isotope will never spontaneously change into a different element, which is what happens to radioactive isotopes. Helium, with two protons and two neutrons, is the lightest “doubly magic ...
