  2. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide atmospheric concentration since 1978 Annual growth rate of atmospheric nitrous oxide since 2000 Earth's nitrous oxide budget from the Global Carbon Project (2020) [57] Nitrous oxide is a minor component of Earth's atmosphere and is an active part of the planetary nitrogen cycle .

  3. Nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_cycle

    [2] [47] This form of nitrogen follows a cascade through the biosphere via a variety of mechanisms, and is accumulating as the rate of its generation is greater than the rate of denitrification. [48] Nitrous oxide (N 2 O) has risen in the atmosphere as a result of agricultural fertilization, biomass burning, cattle and feedlots, and industrial ...

  4. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    Nitrous oxide (N 2 O) 44.013: 306.57: 7.35 (72.5) ... The result is very thin and uniform films deposited at rates much faster than atomic layer deposition, ...

  5. Nitrous oxide (medication) - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_(medication)

    Today the nitrous oxide is administered in hospitals by a relative analgesia machine, which includes several improvements such as flowmeters and constant-flow regulators, an anaesthetic vaporiser, a medical ventilator, and a scavenger system, and delivers a precisely dosed and breath-actuated flow of nitrous oxide mixed with oxygen. [citation ...

  6. Greenhouse gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_monitoring

    Concentrations in ppm of the major greenhouse gases between 1978 and 2010. Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry.

  7. Inhalation sedation - Wikipedia

    en.wikipedia.org/wiki/Inhalation_sedation

    Nitrous oxide flow is only allowed via an opened valve when there is flow of oxygen to the system. In any circumstances when oxygen flow is less than 30%, nitrous oxide stops flowing. This prevents the potential delivery of 100% nitrous oxide and it becomes a standard on every sedation unit made today. [9] Reservoir bag

  8. Nitrous oxide engine - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_engine

    A nitrous oxide engine, or nitrous oxide system (NOS) is an internal combustion engine in which oxygen for burning the fuel comes from the decomposition of nitrous oxide, N 2 O, as well as air. The system increases the engine's power output by allowing fuel to be burned at a higher-than-normal rate, because of the higher partial pressure of ...

  9. Aerosol spray dispenser - Wikipedia

    en.wikipedia.org/wiki/Aerosol_spray_dispenser

    Nitrous oxide and carbon dioxide are also used as propellants to deliver foodstuffs (for example, whipped cream and cooking spray). Medicinal aerosols such as asthma inhalers use hydrofluoroalkanes (HFA): either HFA 134a (1,1,1,2,-tetrafluoroethane) or HFA 227 (1,1,1,2,3,3,3-heptafluoropropane) or combinations of the two.
