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 ...

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 ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...

Charge carriers have been confined by exploiting the small difference between the bandgap energies of the two naturally occurring stable isotopes of carbon. Many high-speed electronic and ...

The application of Stable Isotopes measurements can be used to integrate, indicate, record and trace fundamental ecological processes. Rapid technological advances over the past decade have greatly ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

Utilizing Hg stable isotopes to reliably trace the origin of Hg in the geologic record has been reported in a number of studies. Mercury isotope records of Hg enrichments for volcanic origin ...

We have established a nationally recognised non-compound specific stable isotope analysis facility that provides analytical services to both internal and external research users. High resolution and ...

This policy deals with radioisotopes. For stable isotopes, see Stable Isotopes on SIO Ships. The SIO Isotope Use Committee (the IUC) reviews all experiments involving natural isotopes and ...

A variety of foods is needed to cover a person’s nutrient needs. Stable isotopes can be used to assess diet quality and the effects on vitamin A and nutritional status. Diet quality refers to both the ...
