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 ...

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 ...

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 ...

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 ...

This measurement provides carbon, oxygen and “clumped” isotope ratios for carbonate minerals, which enables us to reconstruct the temperature at which the carbonate formed, along with information ...

In 1940 Martin Kamen discovered radioactive carbon-14 (an isotope of carbon) and found that it had a half-life of about 5,700 years. Scientists had also found that some of the nitrogen in the ...

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 ...

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

A research team led by Prof. Zhang Zhirong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences ...
