Application
Nitrous oxide can be used as:
N2O can also be reacted with N-heterocyclic olefins (NHOs) to form electron-rich azo-bridged NHO dimers.
- A nitrogen donor to synthesize alkynyl and alkenyl substituted triazenes by coupling reaction with lithium amides and organomagnesium compounds.
- A reagent to synthesize azoimidazolium dyes.
N2O can also be reacted with N-heterocyclic olefins (NHOs) to form electron-rich azo-bridged NHO dimers.

Identification of specific landscape areas with high and low groundwater denitrification potential is critical for improved management of agricultural nitrogen (N) export to ground and surface waters and indirect nitrous oxide (N₂O) emissions. Denitrification products together with concurrent hydrogeochemical properties

Nitrous oxide (N2 O) emissions from soils contribute significantly to global warming. Mitigation of N2 O emissions is severely hampered by a lack of understanding of its main controls. Fluxes can only partly be predicted from soil abiotic factors and

Herbivores are a significant source of nitrous oxide (N(2)O) emissions. They account for a large share of manure-related N(2)O emissions, as well as soil-related N(2)O emissions through the use of grazing land, and land for feed and forage production. It
