In October 2020, they reported room-temperature superconductivity at 288 K (at 15 °C) in a carbonaceous sulfur hydride at 267 GPa, triggered into crystallisation via green laser. [25] [26] This was retracted in 2022 after flaws in their statistical methods were identified [27] and led to questioning of other data.
Superconductivity for sulfur hydrides without carbon was first reported in 2015. [12] On 14 October 2020, a paper by Elliot Snider, et al. from the Dias lab was published, claiming that carbonaceous sulfur hydride was a room-temperature superconductor. [1] Two years later, the paper was retracted.
X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory .
High-temperature superconductivity represents a potential breakthrough across multiple fields of technology, from MRIs to levitating trains, hoverboards and computing. Scientists at the Department ...
These act as a single particle and can pair up across the graphene's layers, leading to the basic conditions required for superconductivity. [71] In 2020, a room-temperature superconductor (critical temperature 288 K) made from hydrogen, carbon and sulfur under pressures of around 270 gigapascals was described in a paper in Nature.
Breakthrough would mark ‘holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications’ – but it is a long way from being proven
Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).
(same H-M symbol) Space group: C2/m: Lanarkite is a mineral, a form of lead sulfate with formula Pb 2 ... a material evaluated for room-temperature superconductivity. [2]
