Researchers reach superconductivity at ambient pressure, record high temperature — milestone of -122°C reached by using pressure quenching, still 140 degrees off room temperature target
- Researchers report ambient-pressure superconductivity at 151 K from Hg1223 using pressure quenching.
- The record surpasses the prior 133 K milestone under ambient conditions.
- Pressure quenching preserves the high-temperature state after decompression.
- The discovery aims to enable practical superconducting systems at lower costs and simpler setups.
- The team used Hg1223, a mercury-based cuprate superconductor, in their experiments.
- High pressure strengthens electron pairing but is usually unstable when decompressed.
- Ambient-pressure superconductivity could simplify lab tools and accelerate R&D.
- The study highlights potential applications across electronics, energy, and medical fields.
- Researchers plan further work to stabilize ambient-temperature superconductivity for practical use.
- The finding is part of ongoing efforts to push superconductivity research toward real-world viability.
