Plastic Ice VII
Scientists have confirmed Plastic Ice VII, a new phase of water, under extreme pressure and temperature conditions. Led by Livia Bove from Sorbonne University, the discovery expands knowledge of water’s behavior in planetary environments. Unlike regular ice, Plastic Ice VII has a crystalline structure but allows molecular rotation. It forms above 450 K (177°C) and at pressures over 3 GPa. Researchers used quasi-elastic neutron scattering and diamond-anvil cells for observation. Found in icy moons like Ganymede and Titan, it has implications for planetary science, astrobiology, and material engineering, potentially leading to advancements in technology for extreme environments.
