Ethan Siegel, Forbes, 7 Sep. 2021 In fact, Boeri and colleagues published a paper in Physical Review B on 15 July predicting that lanthanum borohydride (LaBH8) could superconduct at 126 K under just 50 GPa of pressure. Robert F. Service, Science | AAAS, 26 Aug. 2021 In 1968, Neil Ashcroft, a theoretical physicist at Cornell University, suggested putting hydrogen under intense pressure would turn the gas into a solid lattice able to superconduct. Robert F. Service, Science | AAAS, 26 Aug. 2021 Other theorists have predicted that hydrides such as calcium hydride or actinium hydride should superconduct at close to room temperature—and at a pressure considerably less than that needed for CSH. Robert F. Service, Science | AAAS, 26 Aug. 2021 In the mid-1980s, experiments with copper oxides with the elements lanthanum and barium broke the longstanding temperature record by several degrees, being found to superconduct at temperatures greater than 30 K. Ethan Siegel, Forbes, 7 July 2021 To superconduct in these materials, the electrons have to find a partner to form what's called a Cooper pair. John Timmer, Ars Technica, 14 Oct. 2020 But even within those extreme parameters, this is still the first material to superconduct at a temperature even nearly this high. Caroline Delbert, Popular Mechanics, 15 Oct. 2020 By using ultra-high pressures, researchers have been able to force hydrogen into solids that turned out to superconduct at temperatures that could be reached without resorting to liquid nitrogen.
