Oak Ridge National Laboratory is boosting isotope production to secure the US supply chain after Russian shortages.

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...

The initial reference materials for H, C, O isotope measurements, Pee Dee Belemnitella (known widely as PDB) and Standard Mean Ocean Water (SMOW) have long been exhausted. However, they can be linked ...

Lead (Pb) isotopes provide valuable insights into the origin of Pb within a sample, typically allowing for reliable fingerprinting of their source. This is useful for a variety of applications, from ...

For decades, scientists have relied on a chemical fingerprint inside water molecules to determine where plants get their moisture. The method shaped our understanding of drought resilience, ...

Sixty years ago, the very first samples of rainwater were collected for the Global Network of Isotopes in Precipitation (GNIP), while the science of isotope hydrology was still taking its first steps.

An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the periodic table and having almost identical chemical behavior, but ...

When Irish criminal investigators couldn’t identify a dismembered body, parts of which they found around a canal near Dublin in the spring of 2005, Wolfram Meier-Augenstein got a phone call. An ...
