Graphite, diamond, fullerenes, and graphene are all carbon allotropes, and their diverse properties arise from the combination and arrangement of multiple types of bonds between their carbon atoms.—IEEE Spectrum, 23 June 2022 Enlarge / Graphene is a remarkable allotrope, deserving of further study.—Kevin Purdy, Ars Technica, 30 July 2024 In 1955, however, labs at General Electric built on earlier research to create diamonds from graphite, another carbon allotrope, that had been subjected to extremes of pressure (nearly 1 million pounds per square inch) and temperature (3,100 degrees Fahrenheit).—Gemma Tarlach, Discover Magazine, 5 Apr. 2018 And now, according to a paper today in Science, a team of researchers in Europe has succeeded in creating a strange new allotrope: an 18-carbon ring that had eluded labs for decades.—Bill Andrews, Discover Magazine, 14 Aug. 2019 Graphene is a super material and an allotrope of carbon that’s made up of a layer of atoms arranged in a two-dimensional honeycomb nanostructure.—Mark Sparrow, Forbes, 10 Nov. 2021 Therrien is bullish about the long-term potential of geometrical frustration to synthesize novel allotropes of carbon and other elements.—W. Wayt Gibbs, Science | AAAS, 12 Nov. 2019 Altogether, then, this allotrope of carbon looks likely to have a profitable future.—The Economist, 5 Oct. 2019 More Biology and Tech The e-tattoo is built from the thermoplastic polyvinylidene fluoride and graphene, which is an allotrope of carbon that's 100 times stronger than steel.—Daisy Hernandez, Popular Mechanics, 26 June 2019
