The molecular structure of plastic ice VII has surprised scientists (Representative picture). Under normal conditions, water exists in three phases: solid (ice), liquid (water), and gas (vapour or ...
Before researchers can measure these reactions and incorporate their impacts in global atmospheric models, researchers first ...
Our understanding of the molecular dynamics of growing crystals is quite primitive, and it is generally not possible to explain why even simple crystals develop their characteristic shapes. A case in ...
Plastic Ice VII allows water molecules to rotate freely within a rigid crystalline structure. This phase was first predicted in 2008, but scientists have now provided solid evidence of its existence.
