A recent study published in Nature discusses findings from quasi-elastic neutron scattering experiments that observe a new phase of ice, termed 'plastic ice', which exhibits a body-centered cubic structure characteristic of ice VII. Conducted at high pressures (up to 6 GPa) and elevated temperatures (450 to 600 K), these measurements indicate that while the molecules are fixed in a solid-like arrangement, they retain liquid-like rotational dynamics, adding to our understanding of water's behavior under extreme conditions, especially relevant for planetary science.
Recent quasi-elastic neutron scattering measurements reveal the presence of a body-centered cubic structure in water ice that exhibits liquid-like dynamic properties.
This study presents unedited findings on plastic ice, a phase previously not observed, contributing significantly to our understanding of water's behavior in extreme conditions.
