U.S. National Science Foundation-funded researchers have stabilized a composite material in a superconducting state at ambient or normal, everyday pressure. Their technique, called the "pressure-quench protocol," offers a new approach for exploring and developing superconducting materials. Superconducting materials have the potential to enable highly efficient electronic devices and minimal energy loss in power grids.

Superconducting materials typically exhibit zero electrical resistance only at very low temperatures or very high pressures, depending on the material. Researchers at the University of Houston overcame these limitations by using their pressure-quench technique to stabilize a composite of bismuth, antimony and tellurium in a superconducting state under ambient pressure. This study, published in Proceedings of the National Academy of Sciences, also included contributions from researchers at the University at Buffalo and the University of Illinois Chicago.
