How the Record Was Broken

University of Houston researchers have set a new superconductivity record, achieving zero-resistance electricity flow at 151 Kelvin under normal pressure, surpassing the 30-year-old ambient-pressure benchmark of 133 Kelvin. How the Record Was Broken Physicists Ching-Wu Chu and Liangzi Deng achieved the breakthrough using a technique called pressure quenching. They exposed a material to high pressure … Read more

Houston Physicists Smash 30-Year Superconductivity Record

The Physics Behind the Breakthrough

A 151-Kelvin superconductor operating at ambient pressure could redefine energy efficiency—but the race to commercialize it is just beginning. University of Houston physicists have shattered a 30-year-old record for high-temperature superconductivity at ambient pressure, achieving a transition temperature of 151 Kelvin—about -122°C—without requiring extreme compression. The breakthrough, published in the Proceedings of the National Academy … Read more
