Examples of superconductor in a Sentence

Recent Examples on the Web Two weeks later, follow-up preprint papers from more prominent superconductor laboratories have found that LK-99 isn’t a superconductor after all, and is actually a less efficient conductor than copper at room temperature. Darren Orf, Popular Mechanics, 9 Aug. 2023 Chang stressed that the levitation observed does not necessarily mean that the material is a superconductor—there are many materials that exhibit strong diamagnetism, which could be hard to distinguish from perfect diamagnetism, that are not superconductors, such as bismuth and graphite. Will Henshall, Time, 3 Aug. 2023 Many scientists were skeptical, however, because an earlier superconductor paper by Dr. Dias and his colleagues, also published in Nature, had already been retracted. Kenneth Chang, New York Times, 26 July 2023 The discovery in 2015 that hydrogen sulfide is a superconductor was consistent with computer simulations conducted the year before. Davide Castelvecchi, Scientific American, 17 Nov. 2023 Crucially, when this happens, the resistance along the length of the material drops to zero, and the electrons travel around the edges without losing any energy, achieving an effect similar to that of a superconductor. IEEE Spectrum, 30 Oct. 2023 Richard Greene, a physicist studying superconductors at the University of Maryland, generally agrees. Lauren Leffer, Scientific American, 14 Aug. 2023 The discovery of a demon is particularly important for understanding superconductors. Darren Orf, Popular Mechanics, 14 Aug. 2023 Griffin found that inserting copper atoms into lead apatite caused the material’s atoms to rearrange in an unexpected way that resembles existing superconductors.
