Preposition: in

  • water: The conventional method of concentrating deuterium in water uses isotopic exchange in hydrogen sulfide gas, although more advanced techniques are being developed.

Modifies a noun

  • atom: Such neutrons would be produced in the fusion of deuterium atoms in the glass flask.
  • oxide: I am also intrigued by the idea of growing heavy water ( deuterium oxide ) crystals.
  • lamp: Deuterium lamps however may be used from 370 nm down to 200 nm.
  • exchange: Also it is of considerable interest to produce bigger protein crystals for neutron diffraction studies of hydrogen deuterium exchange, in particular cases.

Noun used with modifier

  • isotope: Ordinary hydrogen has only one proton in the nucleus, while the isotope deuterium has one proton + one neutron.
