and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

Isotopes have the same number of protons but ... Loggerhead turtle movements reconstructed from O and C profiles from commensal barnacle shells. Estuarine, Costal and Shelf Science 16, 345-349 ...

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 National Nuclear Corporation’s (CNNC) first-ever commercial reactor for the production of isotopes has officially opened. Called the Qinshan Nuclear Power Base plant, it has already ...

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.

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 ...

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 ...
