Sentences with phrase «deuterium atoms»
Deuterium atoms are a type of hydrogen atom, but with an extra particle called a neutron. They are used in scientific research because they can help us understand how molecules work and how materials interact. Full definition
The team succeeded by using deuteration, or the substitution of deuterium atoms for hydrogen atoms, to study how hydroxyl is produced.

The catastrophic collapse of these bubbles heats the deuterated acetone to the point at which deuterium atoms collide and fuse, the authors argue.
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).
When surrounded by deuterium atoms (heavy hydrogen), that voltage gives the atoms an electric charge and then accelerates them into a nearby solid target containing additional deuterium.
When the researchers applied a current to the cell, they thought deuterium atoms from heavy water that had penetrated into the palladium cathode were fusing to form helium atoms.
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.
In the 1950s, deuterium was used in thermonuclear weapons because nuclear fusion of deuterium atoms (or of deuterium and the heavier hydrogen isotope, tritium) releases tremendous energy.
About 1 in 400 deuterium atoms in the sun are made in this proton - electron - proton, or pep, react
When the deuterium atoms smash together, some of them fuse, producing a helium nucleus and a neutron.
The chemical properties of deuterium atoms are identical to those of hydrogen atoms, but because they are twice as large in mass, they have a much slower tunneling speed.
The nucleus of a deuterium atom contains one proton and one neutron; in hydrogen, the proton stands alone.
For example, in our oceans, there is one deuterium atom to every 6420 hydrogen atoms.
Yamaguchi also detected a difference in mass of 0.64 per cent between the deuterium atoms which fuse and the helium - 4 that they generate.
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».
The authors looked for a very rare molecule of doubly isotope - substituted methane, known as 13CH3D — a molecule with both an atom of carbon - 13 and a deuterium atom.
Finally, Webb will look at ratios of heavy water — water molecules that contain a deuterium atom instead of hydrogen — to water in the planet - forming disks, helping trace how the water formed and under what conditions.
Specifically, the team focused on 13CH3D - a molecule with both an atom of carbon - 13 and a deuterium atom.
