dern method of refining crude oil. Costin Nenițescu found new methods for the synthesis of pirilium salts, of carbenes, tryptamine, serotonin, two new syntheses for the indole nucleus, and a new method of polymerisation of ethylene.
Several mathematicians distinguished themselves as well, among them: Gheorghe Țițeica, Spiru Haret, Grigore Moisil, Miron Nicolescu, Nicolae Popescu and Ștefan Odobleja; the latter is also regarded as the ideological father behind cybernetics.
Notable physicists and inventors also include: Horia Hulubei in atomic physics, Șerban Țițeica in theoretical physics, Mihai Gavrilă specialized in quantum theory and discoverer of the atomic dichotomy phenomenon, Alexandru Proca (known for the first meson theory of nuclear forces and Proca's equations of the vectorial mesonic field), Ștefan Procopiu known for the first theory of the magnetic moment of the electron in 1911 (now known as the Bohr-Procopiu magneton), Theodor V. Ionescu, the inventor of a multiple-cavity magnetron (1935), a hydrogen maser in 1947, 3D imaging for cinema/television in 1924 and hot deuterium plasma studies for controlled nuclear fusion, Ionel Solomon known for the nuclear magnetic resonance theory in solids, Solomon equations and photovoltaic devices, Petrache Poenaru, Nicolae Teclu and Victor Toma, with the latter known for the invention and construction of the first Romanian computer, the CIFA-1 in 1955.
The nuclear physics facility of the European Union's proposed Extreme Light Infrastructure (ELI) laser will be built in Romania. Romania currently has 1,400 MW of nuclear power capacity by means of one active nuclear power plant (Cernavodă) with 2 reactors, which constitutes around 18% of the national power generation capacity of the country. This makes Romania the 23rd largest user of nuclear power in the world
