Ambient-pressure superconductivity record broken after 33 years

U.S. researchers raised the superconducting transition temperature at ambient pressure to 151K, about minus 122 degrees Celsius, breaking a 33-year record. The team at the University of Houston and the Texas Center for Superconductivity used mercury-based copper-oxide ceramic Hg1223 and a “pressure quench” method that preserves high-pressure properties after pressure is removed. The result remained stable for about two weeks and was reproduced in five samples.
