The reaction uses photoredox-mediated hydrogen-atom transfer to replace the hydrogens at C–H bonds adjacent to amines with deuterium or tritium from D 2 O or T 2 O (Science 2017, DOI: 10.1126 ...

Hydrogen-2 (²H or Deuterium) Hydrogen-2, or deuterium (²H), is a stable isotope with one additional neutron compared to hydrogen-1 (¹H). ... For instance, labeling a single carbon atom in a glucose ...

Deuteration: Replacement of a hydrogen atom in a molecule with its heavy isotope, deuterium. Isotope Labeling: Incorporation of an isotopic variant of an element into a compound to aid in tracking ...

A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium ...

The deuterium atom would eventually slip from its grip and snap back toward the other deuterium atom, initiating an oscillation, or vibration. "What we are really seeing is the result of a ...

Deuterium, a heavier but less abundant version of the hydrogen atom, has many practical applications. Unfortunately, producing deuterium and using it to protect silicon-based semiconductors ...

More than 70% of the Earth is covered with water—H2O. An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are replaced by deuterium ...

Deuterium oxide (D 2 O), aka “heavy water”, is the form of water that contains two atoms of the 2 H, or D, isotope. The term heavy water is also used for water in which 2 H atoms replace only some of ...

Deuterium is an isotope of hydrogen that has a single proton and single neutron in its nucleus. Its atomic weight is therefore twice that of the much more common hydrogen atom, which lacks a neutron.
