Not exact matches

Consider this: One tablespoon of liquid hydrogen fuel — a mix of deuterium and tritium — would produce the same energy as 28 tons of coal.

When the deuterium atoms smash together, some of them fuse, producing a helium nucleus and a neutron.

According to the data from DASI, it amounts to a mere 4.5 percent of the universe's total mass and energya number that accords well with an estimate made in 1998 based on the amount of the element deuterium produced during the big bang.

Meanwhile, fusion researchers in Japan and the United States have produced temperatures above 900 million ° F in plasmas of deuterium and tritium, which are isotopes of hydrogen.

The interaction produces more deuterium than hydrogen.

The team succeeded by using deuteration, or the substitution of deuterium atoms for hydrogen atoms, to study how hydroxyl is produced.

Clive Semmens's fear that a deuterium - tritium fusion reactor can't produce enough tritium for its own needs is unjustified (15 March,...

Clive Semmens's fear that a deuterium - tritium fusion reactor can't produce enough tritium for its own needs is unjustified (15 March, p 32).

When deuterium and helium - 3 fuse, they produce high - energy protons rather than neutrons.

As deuterium is thought to have been produced in the big bang, it should once have had similar abundances on all the planets in the solar system.

This is the start of a whole sequence of reactions: Protons collide with deuterium to produce helium - 3; helium - 3s combine to give helium - 4 plus protons; other reactions produce lithium, beryllium, and boron.

The International Thermonuclear Experimental Reactor (ITER) aims to produce 500 megawatts of power by burning a plasma of deuterium and tritium held in place by superconducting magnets in a doughnut - shaped vessel called a torus.

When two deuterium atoms fuse in his experiments, they produce helium - 4 together with energy, in the form of photons and lattice vibrations called «phonons».

Pons and Fleischmann asserted that passing a current through heavy water — water containing deuterium, a heavy isotope of hydrogen — between palladium electrodes produced a huge amount of heat.

Yet, even today he doesn't know how a commercial energy source could be constructed for the palladium - deuterium system, despite his many experiments that have produced significant excess heat correlated with helium production.

Perhaps, the scientists thought, the bubbles would get so big that their collapse would produce temperatures near 10 million degreeshot enough to cause a few deuterium atoms in the acetone to fuse into helium or tritium (hydrogen with two extra neutrons).

If you have a proton and two neutrons, that's tritium and for various technical reasons, it's much easier to make deuterium and tritium come together to produce fusion.

Although future ADS systems will use protons beams and a heavy metal target to produce neutrons, Guinevere's neutron source — deuterium ions hitting a tritium target — is powerful enough to simulate how a bigger machine like Myrrha will behave, says Abderrahim.

The newfound particles are produced when two protons and an electron interact to make deuterium, a heavy form of hydrogen that helps feed the sun's fusion.

To measure the number of electron - neutrinos reaching Earth, the SNO team monitored miniscule flashes of light produced when the particles interact with molecules of heavy waterin which deuterium atoms replace the hydrogen atoms.

Even if deuterium were unstable with a weaker strong force, it would still form briefly and fall apart again, producing proton and neutrons.
