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; ...

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

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 ...

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 ...

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.

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 ...
