In a letter to the editor published in the Dec. 4, 1913, issue of Nature, English radiochemist Frederick Soddy proposed the isotope concept—that elements could have more than one atomic weight. The ...

The past October marked an exciting time for those in the field of isotopic science. Two brand new approaches to isolate and enrich light elements have been reported. Although a variety of elements ...

PORTLAND, Ore. — You might have thought that scientists had already cataloged the 118 natural elements–from hydrogen to silicon to uranium–and their various isotopes. Unfortunately, only the first ...

Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Isotopes are forms of a chemical element with ...

This publication is a result of the Coordinated Research Project (CRP) F32008 "Global Monitoring of Nitrogen Isotopes in Atmospheric Waters" implemented by the IAEA’s Isotope Hydrology Section in 2018 ...

Hydrogen isotope separation technologies play a pivotal role in energy production, nuclear safety and advanced research. These technologies aim to distinguish between remarkably similar isotopic ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission ...

With five more protons than should be stable, the newly discovered nitrogen-9 isotope sits right on the borderline of physical possibility. When you purchase through links on our site, we may earn an ...
