These three oxygen isotopes occur naturally in proportions of 99.76%, 0.04%, and 0.2%, respectively. Hence, out of these stable isotopes of oxygen, O 16 is the most common, whereas the other two ...

Millions of years ago, long-necked sauropods and snarling Tyrannosaurs roamed a world thick with heat, teeming forests, and ...

A previously unexploited source of information is now throwing new light on Earth's climate during the age of dinosaurs.

Researchers used stable isotope and proteomic analyses on medieval European skeletons to uncover the details of ancient diets ...

The first 80 elements on the periodic table have stable isotopes. The properties of stable isotopes allow them to be used to understand and manage water and land resources. They are also used in ...

The researchers set up two experiments involving three stable isotopes of oxygen. These are oxygen-16 and oxygen-18, which both have zero nuclear spin, and oxygen-17, which has a nuclear spin of 5/2.

But what do stable isotopes have to do with understanding the source of GHGs? At the event, Federica Camin, an IAEA Reference Materials Specialist, explained how analysing isotopic ratios in GHGs is ...

Scientists have long predicted that this isotope is unusually stable. But initial observations of the 28 O nucleus suggest that this isn’t the case: it disintegrates rapidly after creation, a ...
