Nitrogen in Diamond [PDF]

open access: yesChemical Reviews, 2020
Nitrogen is ubiquitous in both natural and laboratory-grown diamond, but the number and nature of the nitrogen-containing defects can have a profound effect on the diamond material and its properties. An ever-growing fraction of the supply of diamond appearing on the world market is now lab-grown.

Nitrogen and nitrogen oxides

open access: yesMedicine, 2003
Abstract Evaporation of liquid nitrogen from the eye or skin may cause cold burns. It may displace oxygen, causing hypoxic asphyxia. Of the nitrogen oxides NO 2 is most toxic. Following exposure, effects in the peripheral airways and alveoli can be expected; clinical symptoms are usually absent during the first hours after exposure.

Polymeric nitrogen [PDF]

open access: yesPhysical Review B, 1992
Ab initio local-density functional total-energy calculations indicate that a polymeric form should be the stable phase of nitrogen above [approximately] 35 GPa, and that such a polyermic phase is likely to be both energetic and metastable at atmospheric pressure.
