The American biochemist MELVIN CALVIN (1911-1997) succeeded in elucidating the photosynthetic reaction cycle that leads to the fixation of the carbon dioxide molecule as a sugar in the cell. These reaction processes in the dark reaction of photosynthesis are named after him "CALVIN cycle" .
Reversing the basic principle of spectral analysis, WALSH and ALKEMADE developed atomic absorption spectroscopy - [homework help in science](https://domyhomework.club/science-homework/) . With this method, the smallest concentrations of metal ions, e.g. B. in environmental analysis, determine very precisely.
At BASF, acetic acid was obtained completely synthetically from methanol and carbon monoxide for the first time . However, the synthetic process could not replace the biochemical production by vinegar fermentation.
Synthetic industrial diamonds were first produced in the USA . To turn graphite into diamond, high pressures of about 5 ⋅10^9 Pa and high temperatures of 1,200 to 1,600 ° C are required.
In order to bring order to the diversity of organic compounds, the IUPAC adopted general rules for the nomenclature of aliphatic - [chemistry problem solver online](https://domyhomework.club/chemistry-problem-solver/) , cyclic and heterocyclic compounds.
The first major accident occurred in a nuclear reactor in Windscale, England . Due to an operator error, the reactor overheated on October 10, 1957 and caught fire. A radioactivity of 7 ⋅10^14th Bq released. The damage caused by this incident was covered up by the NPP operators and the British government.
In the Soviet Union, the liquid rocket "Vostok" was launched for the first time on August 3rd. About 2 months later, the first artificial satellite on earth, Sputnik 1, was transported into space with this rocket .
