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.
The acquisition of Tognum by the two companies was completed in September 2011 and the business continued to trade as Tognum AG until January 2014, when it was renamed Rolls-Royce Power Systems AG. Rolls-Royce Holdings confirmed in March 2014 that they would purchase Daimler AG's 50% stake in the joint venture.
