The team used a new technique to create a pure isotope of the element, and the discovery could make protection of this rare ...

This isotope of hydrogen is called deuterium ... York University tried to find a definitive value for the density of pure water, but despite meticulous experiments, they kept getting varying ...

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 ...

Whereas scientists could only use natural uranium in a uranium machine, Heisenberg noted that they could use pure uranium 235, a rare isotope, as an explosive. In the summer of 1940, Carl ...

The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio mass spectrometers designed to measure the relative abundance of stable isotopes of light elements and molecules. These ...

Morgan, who prepared a specimen of pure antimony trimethyl for this purpose ... The most trustworthy measurements show that the masses of the isotopes of antimony are most probably less than ...

Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how ...

In its pure form it is a silver-coloured heavy metal ... In its natural state, it consists of three isotopes (U-234, U-235 and U-238). Other isotopes that cannot be found in natural uranium are U-232, ...

The study, featured on the Dec. 4 cover of the journal Science Advances, used stable isotope analysis to model the diet of the mother of an infant discovered at a 13,000-year-old Clovis burial ...

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 ...
