However, about 1 % of the carbon in the Earth’s biosphere has 6 protons and 7 neutrons (13C) forming the heavy stable isotope of this important element. Stable isotopes do not decay into other ...

Isotope hydrology helps governments find and understand the source of their water supplies – so they can develop management ...

The stable isotope concentrations ... the molar ratio of the heavy-to-light isotopes. Since this ratio is small, we typically present stable isotope abundances relative to an international standard ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how ...
