  • Dissolved Oxygen by the Winkler Method - SERC

    2019-2-4 · Liquid propellants, such as liquid hydrogen (LH 2) and liquid oxygen (LO 2), were suggested already in the 1980s by Tsiolkovsky as combustible propellants for rockets. Liquid helium (LHe) was used for the first time at the end of the twentieth century to cool down to few degrees Kelvin telescopes used in infrared astronomy, as described in . Nowadays, an example of cryogenic application is the near- und …
