Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
Ranga Dias (scientist) are not convinced that hydrogen has been squeezed to a metallic form inside a diamond-tipped anvil in this work. Ranga Dias (scientist) Ranga Dias is a Sri Lankan born scientist, physicist, researcher currently working in the Lyman Laboratory of Physics at Harvard University. He was graduated from Department of Physics, Colombo University Sri Lanka and moved to Washington, USA for Ph.D. work at Washington State University in the field of extreme condensed matter physics. During his Ph.D. research at Washington State University he discovered a new class of highly conducting metallic and superconducting polymers; his CV lists 7 papers published
