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.
In 1991, the company stopped importing cars into the U.S. Fiat bought Maserati in 1993 and variants of the Biturbo continued to be produced until the factory closed in 1997 for a total refurbishing. During this time, Ferrari bought 50 percent of Maserati and went on to acquire full control of the marque.ith only 138 cars produced in that long span, most of Maserati's money came from its other products: spark plugs and car batteries. The Maserati 3500 GT, fitted with a double-overhead-cam inline six, debuted in the mid-1950s.
