🚨 BIG BREAKTHROUGH: A 30-year superconductivity record just got broken 👀! A new mercury-based ceramic superconductor called Hg-1223 just shattered a record that had stood since 1993. Researchers from Houston and the Texas Center for Superconductivity pushed its superconducting temperature from 133 K to 151 K. That’s about −140 °C → −122 °C, the highest superconducting temperature ever achieved at normal pressure.
