Deuterium in a sentence

Applications Ionized deuterium in a fusor reactor giving off its characteristic pinkish-red glow Emission spectrum of an ultraviolet deuterium arc lamp Deuterium has a number of commercial and scientific uses.

Before nucleosynthesis began, the temperature was high enough for many photons to have energy greater than the binding energy of deuterium; therefore any deuterium that was formed was immediately destroyed (a situation known as the deuterium bottleneck).

Deuterium lamps Deuterium HCL or even hydrogen HCL and deuterium discharge lamps are used in LS AAS for background correction purposes.

Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, as the basic or primordial ratio of hydrogen-1 (protium) to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time.

The discovery of deuterium, coming before the discovery of the neutron in 1932, was an experimental shock to theory, but when the neutron was reported, making deuterium's existence more explainable, deuterium won Urey the Nobel Prize in chemistry in 1934.

There is thought to be little deuterium in the interior of the Sun and other stars, as at temperatures there nuclear fusion reactions that consume deuterium happen much faster than the proton-proton reaction that creates deuterium.

Deuterium and Big Bang nucleosynthesis main Deuterium is thought to have played an important role in setting the number and ratios of the elements that were formed in the Big Bang.

Deuterium can be detected by femtosecond infrared spectroscopy, since the mass difference drastically affects the frequency of molecular vibrations; deuterium-carbon bond vibrations are found in locations free of other signals.

Deuterium seeAlso Tritium is also produced in heavy water-moderated reactors whenever a deuterium nucleus captures a neutron.

During the 1970s, there were major efforts to find processes that could produce deuterium, but those revealed ways of producing isotopes other than deuterium.

In Galonsky's opinion, the observed neutrons were too high in energy to be from a deuterium -deuterium (d-d) fusion reaction.

Organic chemistry Deuterium oxide is often used as the source of deuterium for preparing specifically labelled isotopologues of organic compounds.

The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth's oceans (156 atoms of deuterium per million hydrogens).

The denser the initial universe was, the more deuterium would be converted to helium-4 before time ran out, and the less deuterium would remain.

The latter two nuclei are not stable or nearly stable, and therefore so is this type of deuterium (meaning that it is indeed a highly excited state of deuterium).

This has been interpreted to mean that less deuterium has been destroyed in star formation in our galaxy than expected, or perhaps deuterium has been replenished by a large in-fall of primordial hydrogen from outside the galaxy.

To date, the highest neutron flux achieved by a fusor-like device has been 3 × 10 11 neutrons per second with the deuterium-deuterium fusion reaction.

They only ever made that with deuterium.

Deuterium is abundant: it makes up 0.02% of all the natural hydrogen in seawater, from which it can be extracted.

It exists naturally but often the ratio of water to deuterium can reveal information.
