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
Ruth Cameron (scientist) Ruth Cameron (scientist) Ruth Cameron FInstP FIOM3 is a British materials scientist and professor at the University of Cambridge. She is co-director of the Cambridge Centre for Medical Materials. She studies materials that interact therapeutically with the body. Cameron completed her PhD in physics at the University of Cambridge. Cameron's research considers materials which interact therapeutically with the body. She is interested in musculoskeletal repair. Her research considers bioactive biodegradable composites, biodegradable polymers, tissue engineered scaffold and surface patterning. Cameron works with Serena Best on collagen scaffolds for the spin-out company "Orthomimetics". In 1993 she joined the Department of Materials
