New method enables superconductor to break temperature record, achieving room-temperature superconductivity.
Scientists have achieved a new milestone in superconductivity, reaching room-temperature superconductivity at 20.5°C, the highest ever recorded. This breakthrough, led by Ranga Dias's team at the University of Rochester, involved a new method using a hydrogen-nitrogen-lutetium compound under high pressure. Superconductors, which conduct electricity with zero resistance, typically require extremely low temperatures. While previous claims by Dias's team faced scrutiny, this new method and compound, described in Nature, show promise. Achieving room-temperature superconductivity could revolutionize energy transmission, medical imaging, and computing by eliminating energy loss in electrical grids and enabling highly efficient technologies. Further independent verification is ongoing.
