"Revolutionary Ice XXI Phase Detected at Room Temperature Under Extreme Pressure"

Researchers have detected a new phase of ice, known as Ice VI, forming at room temperature under extreme pressure, specifically above 0.96 GPa, revealing complex behaviors of hydrogen bonds.

• The discovery was made by scientists at the Korea Research Institute of Standards and Science using a diamond anvil cell to apply extreme pressure to water at room temperature.
• Ice typically crystallizes at temperatures below 0 C, but under pressures exceeding 0.96 GPa, water transitions to Ice VI, showcasing unique properties of hydrogen bonds.
• The process of crystallization involves a complex distortion of the hydrogen-bonded network, highlighting how temperature and pressure interplay to create various ice phases.
