A team at the Texas Center for Superconductivity used a pressure-quenching technique on a mercury-based copper-oxide ceramic to achieve a transition temperature of 151 K at ambient pressure, surpassing a record that had stood since 1993.

Researchers use pressure quenching to lock in a record superconducting transition temperature of 151 K at ambient pressure, surpassing a 33-year-old record.
