Repurposing deep-Earth tools in the hunt for practical superconductors

Scientists are exploring the potential of repurposing deep-Earth simulation tools to develop practical superconducting materials. Superconductors, which transmit electricity without resistance, could revolutionize fields like medicine and quantum computing if functional at normal pressures and relatively high temperatures. Researchers led by Lisa Pfefferle are using the Kawai multi-anvil press, originally designed to study Earth's deep mantle, to investigate materials such as sulfur trihydride (H3S), which exhibits superconductivity under extreme pressures. While H3S demonstrates superconductivity at around -23°C (-9°F) under pressures equivalent to those found 3,200 km below Earth’s surface, its instability and the impracticality of maintaining such high pressures hinder its application. The team aims to stabilize H3S and maintain its superconductivity under more feasible conditions, collaborating with institutions including Yale and the U.S. Navy.
