2]O is caused by decreasing the possibility of biochemical processes running through the appropriate energy levels in deuterium
atoms, which, being caused by mass difference, are spatially shifted towards the nucleus in comparison with analogous levels in hydrogen.
ethanol from maize, a Hatch-Slack type plant with high deuterium
The cell contained an electrolyte of "heavy water" composed of oxygen and deuterium
in its bottom half, along with palladium electrodes, and various supporting internal parts made of Teflon.
In the Indiana University study, Stephenson's team collided a beam of deuterons into a target of deuterium
Once in ammonia, deuterium
atoms "prefer" to stay there when temperatures are extremely low, says Lis.
and one South Korean patent covering the use of deuterium
in semiconductor devices.
CTP-518 is a novel HIV protease inhibitor developed from Concert's deuterium
chemistry platform by replacing certain key hydrogen atoms of atazanavir with deuterium
The one-proton--one-neutron version, called deuterium
, behaves chemically like hydrogen and can form water and other compounds.
Two electrochemists claimed then to have sparked fusion at room temperature by passing electric current through a bath of water in which ordinary hydrogen is replaced by deuterium
, a heavier isotope.
Concert believes these findings represent the first reported clinical data demonstrating that deuterium
substitution can alter a drug's metabolism to reduce the potential for drug-drug interactions in humans.
The substance was labeled with deuterium
atoms, a heavy form of hydrogen, to make it detectable in the blood.
In the May 18 SCIENCE, scientists reported that C/1999 S4 is the first comet whose ratio of deuterium
to hydrogen is similar to that found in water on Earth.
