    en.wikipedia.org/wiki/Oxidizing_agent

    The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

    en.wikipedia.org/wiki/Trimix_(breathing_gas)

    It is used in deep commercial diving, during the deep phase of dives carried out using technical diving techniques, [1] [2] and in advanced recreational diving. [3] [4] The helium is included as a substitute for some of the nitrogen, to reduce the narcotic effect of the breathing gas at depth and to reduce the work of breathing. With a mixture ...

    en.wikipedia.org/wiki/Hypergolic_propellant

    LOX has a density of 1.14 g/ml, while on the other hand, hypergolic oxidizers such as nitric acid or nitrogen tetroxide have a density of 1.55 g/ml and 1.45 g/ml respectively. LH2 fuel offers extremely high performance, yet its density only warrants its usage in the largest of rocket stages, while mixtures of hydrazine and UDMH have a density ...

  7. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    The excimers used for lasers may be noble gas dimers such as Ar 2, Kr 2 or Xe 2, or more commonly, the noble gas is combined with a halogen in excimers such as ArF, KrF, XeF, or XeCl. These lasers produce ultraviolet light, which, due to its short wavelength (193 nm for ArF and 248 nm for KrF), allows for high-precision imaging.

    The least stable is 10 He, with half-life 260(40) yoctoseconds (2.6(4) × 10 −22 s), though 2 He may have an even shorter half-life. In Earth's atmosphere, the ratio of 3 He to 4 He is 1.343(13) × 10 −6. [5] However, the isotopic abundance of helium varies greatly depending on its origin.

  9. Liquid oxygen - Wikipedia

    en.wikipedia.org/wiki/Liquid_oxygen

    Liquid oxygen is the most common cryogenic liquid oxidizer propellant for spacecraft rocket applications, usually in combination with liquid hydrogen, kerosene or methane. [11] [12] Liquid oxygen was used in the first liquid fueled rocket. The World War II V-2 missile also used liquid oxygen under the name A-Stoff and Sauerstoff.
