The researchers conducted an analysis of the nitrogen and carbon isotopes bound to the tooth enamel of 43 fossilized teeth, all of which had been found in South Africa's Sterkfontein caves.

Collagen was extracted and analyzed for bulk stable isotopes of carbon-13 (δ 13 C) and nitrogen-15 (δ 15 N) and compound-specific isotopes of individual amino acids. Radiocarbon dating provided ...

Establishing a robust supply chain for medical-grade isotopes is critical. The radio-decay characteristics of these substrates and the anticipated increase in demand underscore the importance of ...

The Boise State University Isotope Geology Laboratory (IGL) is a state-of-the-art geoanalytical facility for the analysis of trace elements and radiogenic isotopes in Earth materials, using both ...

Introduction: Recent work has proposed that the nitrogen isotopes in marine sediments can be impacted by anaerobic oxidation of methane (AOM), since nitrogen uptake by anaerobic methanotrophic archaea ...

Radiopharmaceutical therapy has been widely adopted owing primarily to the development of novel radiopharmaceuticals. To fully utilize the potential of these RPTs in the era of precision medicine, ...

This data set contains ice core chemistry, timescale, isotope, and temperature data analyzed by several investigators. In January 1998, the collaborative ice-drilling project between Russia, the ...

Each particle has its own charge and its own mass.
