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 [25] [26] This was retracted in 2022 after flaws in their statistical methods were identified [27] and led to questioning of other data.
In superconductivity, Homes's law is an empirical relation that states that a superconductor's critical temperature (T c) is proportional to the strength of the superconducting state for temperatures well below T c close to zero temperature (also referred to as the fully formed superfluid density, ) multiplied by the electrical resistivity ...
High-temperature superconductivity represents a potential breakthrough across multiple fields of technology, from MRIs to levitating trains, hoverboards and computing. Scientists at the Department ...
More recently AC synchronous superconducting machines have been made with ceramic rotor conductors that exhibit high-temperature superconductivity. These have liquid nitrogen cooled ceramic superconductors in their rotors. The ceramic superconductors are also called high-temperature or liquid-nitrogen-temperature superconductors.
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
Texas Center for Superconductivity (TcSUH) Motto: Discover new high temperature superconducting–, energy– and nano– materials, advance their applications in partnerships with industry, and disseminate knowledge through education, outreach, and technology for the benefit of the public and the environment.

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.
The most commonly used conventional superconductor in applications is a niobium-titanium alloy - this is a type-II superconductor with a superconducting critical temperature of 11 K. The highest critical temperature so far achieved in a conventional superconductor was 39 K (-234 °C) in magnesium diboride .
