This and other experiments on combustion were documented in his book Sur la combustion en général, which was published in 1777. [19] In that work, he proved that air is a mixture of two gases; 'vital air', which is essential to combustion and respiration, and azote (Gk. ἄζωτον "lifeless"), which did not support either.
High pressure oxygen storage cylinder, colloquially referred to as an oxygen tank. Oxygen tanks are used to store gas for: medical breathing (oxygen therapy) at medical facilities and at home (high pressure cylinder)
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream.
O2 Residence, a part of the Jumeirah Lake Towers in Dubai, United Arab Emirates; O2 World (Berlin), an indoor arena in Berlin, Germany; O2 World (Hamburg), an indoor arena in Hamburg, Germany; Otoyol 2, a motorway in Turkey called "O2" The O2 (Dublin), the former name of 3Arena; Ring 2 (Aarhus), a road in Aarhus, Denmark, which appears as "O2 ...
Respiratory burst (or oxidative burst) is the rapid release of the reactive oxygen species (ROS), superoxide anion (O − 2) and hydrogen peroxide (H 2 O 2), from different cell types.
The oxygen reduction reaction is an essential reaction for aerobic organisms. Such organisms are powered by the heat of combustion of fuel (food) by O 2.Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer.
O 2 build-up in the Earth's atmosphere.Red and green lines represent the range of the estimates while time is measured in billions of years ago ().Stage 1 (3.85–2.45 Ga): Practically no O 2 in the atmosphere.
Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis.The name therefore uses a different sense of 'dark' than that used in the phrase "biological dark matter" (for example) which indicates obscurity to scientific assessment rather than the photometric meaning.
