Researchers Reveal Disordered Superionic Ice Structure
Researchers using ultrafast X-ray lasers reported in Nature Communications that water under pressures up to 180 gigapascals forms a disordered superionic phase where oxygen atoms lock into mixed crystal arrangements while hydrogen ions flow freely. The experiments match quantum and machine-learning simulations, resolving prior contradictory results. This structure likely exists inside Uranus and Neptune and could affect electrical conductivity and their unusual magnetic fields.
