One common technique for tracking a drug's fate is to label its molecular framework with
heavier isotopes of hydrogen (either deuterium or tritium).
Next, Agee and his colleagues used a laser to extract water molecules trapped within minerals in the meteorite and fed them into a mass spectrometer to calculate the ratio of deuterium,
a heavy isotope of hydrogen, to ordinary hydrogen.
The International Thermonuclear Experimental Reactor (ITER) is a multinational collaboration that represents one of the world's largest attempts to fuse deuterium and tritium, two
heavy isotopes of hydrogen.
That's because during evaporation, water molecules containing deuterium,
a heavy isotope of hydrogen made of one proton and one neutron, get left behind in the ocean.
The energy crisis was over; all you needed was palladium electrodes and heavy water to achieve the room - temperature fusion of deuterium,
a heavier isotope of hydrogen.
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.
When completed in 2018, the reactor will fuse together two
heavy isotopes of hydrogen to release vast quantities of energy.
Not exact matches
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.
Hydrogen atoms contained in water readily bond with the
heavy isotope to form hydrochloric acid gas, which then leaks into space — leaving more
of the lighter
isotope behind.
As precipitation moves inland, water with the
heavier form
of hydrogen falls out first, which creates predictable patterns
of the stable
isotopes ratios
of precipitation across continents.
When ocean storms bump into mountains, raindrops burdened with
heavy isotopes of oxygen and
hydrogen are the first to precipitate.
To understand the origin
of Earth's water, scientists have fingerprinted potential sources, like asteroids and comets, using the ratio
of light to
heavy hydrogen isotopes.

heavy water» (in which the
isotope deuterium replaces «normal»
hydrogen) to detect all three flavors
of neutrinos.
Deuterium (or
heavy hydrogen) is a fragile
isotope that can not survive the high temperatures achieved at the centers
of stars.
