While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

Sulfur isotopes can indicate a person’s proximity to the ocean. Isotopes of carbon and nitrogen, meanwhile, differ according to diet and can be particularly helpful in West-Central Africa ...

Certain chemical elements have more than one type of atom. Different atoms of the same element are called isotopes. Carbon has three main isotopes. They are carbon-12, carbon-13 and carbon-14.

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 ...

China claims that it has achieved success in starting mass production of a radioactive isotope –Carbon-14, which has wide ranging uses in science and medicine. The mass production of carbon-14 ...

First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon-14 isotope. Radiocarbon dating has been used for historical studies ...

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 ...

An isotope is named after the element and the mass number of its atoms. For example, carbon-12 is an isotope of carbon with a mass number of 12.

ASP Isotopes (ASPI) announced that it has started commercial production of enriched Silicon-28 at its second Aerodynamic Separation Process, ...

ASP Isotopes (ASPI) announced that it has started the production of commercial samples of highly enriched Ytterbium-176, following the ...

Naturally-occurring stable isotopes of water and other substances are used to trace the origin, history, sources, sinks and interactions in water, carbon and nitrogen cycles. Stable isotopes can also ...
