Deuterium isotopes are distributed in molecules that contain hydrogen, including, importantly, in all forms of water – also water in our bodies. There’s 33 grams of deuterium in every cubic metre of ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

The deuterium abundance in the Milky Way is therefore an indicator of how much star formation has occurred over the 12 to 13 billion years since the galaxy’s birth. Science News headlines, in ...

The abundance of deuterium provides important insights into the formation of the Milky Way and demonstrates that deuterium is not made by stars or stellar activity. (Stars burn deuterium into ...

The abundance of deuterium provides important insights into the formation of the Milky Way and confirms that deuterium is not made by stars or stellar activity (stars convert deuterium into helium).

These applications need high-purity deuterium, which is expensive because of its low natural abundance. Deuterium enrichment from hydrogen-containing feedstocks, such as seawater, is an important ...

The former method1 gave for the abundance ratio H/D the value 5000 ±500, while two discrepant values2,3 have been obtained by the latter, namely 9000 and 5750±250. Nature - Deuterium Content of ...
