deu·te·ri·um

 (do͞o-tîr′ē-əm, dyo͞o-)
n.
A naturally occurring isotope of hydrogen, H-2, having one proton and one neutron in the nucleus.

deuterium

(djuːˈtɪərɪəm)
n
(Elements & Compounds) a stable isotope of hydrogen, occurring in natural hydrogen (156 parts per million) and in heavy water: used as a tracer in chemistry and biology. Symbol: D or 2H; atomic no: 1; atomic wt: 2.014; boiling pt: –249.7°C
[C20: New Latin; see deutero-, -ium; from the fact that it is the second heaviest hydrogen isotope]

deu•te•ri•um

deu·te·ri·um

(do͞o-tîr′ē-əm)
An isotope of hydrogen whose nucleus has one proton and one neutron and whose atomic mass is 2. Deuterium is used widely as a tracer for analyzing chemical reactions, and it combines with oxygen to form heavy water. Also called heavy hydrogen. See more at hydrogen. See Note at heavy water.

deuterium

An isotope of hydrogen. Its nucleus contains one proton and one neutron and has a relative atomic mass of two.

The deuterium concentration of natural water varies with geographical regions.
Samples of hydrogen from deep inside the Earth, close to the boundary between the core and mantle, have notably less deuterium, indicating this hydrogen may not have come from asteroids.
The company's approach starts with approved drugs in which deuterium substitution has the potential to enhance clinical safety, tolerability or efficacy.
Thus, the deuterium isotope content effect can activate or inhibit intracellular processes.
Deuterium is an excellent moderator with a minimal neutron capture cross-section compared with hydrogen.
The water found on comets previous to this had deuterium levels that were more similar to water found on earth.
But in 2011, a team using the Herschel Space Observatory, an infrared telescope operated by the European Space Agency, took a look at water vapor from the comet Hartley 2 and found that its deuterium signal perfectly matched Earth's water.
Let's consider spacial distribution of energy levels of the same principle quantum number in atoms of hydrogen and deuterium. Taking into account the masses of the nuclei energy levels are separated by the distance.
The astronomers from the US, the UK, and Italy used ALMA to look inside these cores for a unique chemical signature involving the isotope deuterium to essentially take the temperatures of these clouds to see if stars had formed.
Iter is viewed as the next developmental step for tokomak reactors, which use a magnetic field to confine a high-temperature plasma within which deuterium and tritium fuse to release massive amounts of energy.
