Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube. Carbon is capable of forming many allotropes due to its valency.Well-known forms of carbon include diamond and graphite. In recent decades many more allotropes and forms of carbon have been discovered and researched including ball shapes such as buckminsterfullerene and sheets such as graphene.ight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube.

For the current car manufacturers, see Rolls-Royce Motor Cars and Bentley. For other uses, see Rolls-Royce (disambiguation). Rolls-Royce Motors was created in 1973 during the de-merger of the Rolls-Royce car business from the nationalised Rolls-Royce Limited. Vickers acquired the company in 1980 and sold it to Volkswagen in 1998.
After the end of the First World War, Rolls-Royce avoided all the attempts to merge the British car producers and successfully adjusted to the market demands. Since the sales of the 40/50 model were dropping, Rolls-Royce introduced a less expensive Twenty model in the early 1920s. Rolls-Royce acquired Bentley in 1931. Bentleyâs factory in Cricklewood was closed and the production was moved to Rolls-Royceâs facilities in Derby. Until the Second World War, Bentley was kind of a sporty version of Rolls-Royce.
