Phys.org  August 19, 2022 The first-order phase transition between two tetrahedral networks of different density has received strong support from a growing body of work in recent years. An international team of researchers (UK, Italy) showed that this liquid–liquid phase transition in tetrahedral networks can be described as a transition between an unentangled, low-density liquid and an entangled, high-density liquid, the latter containing an ensemble of topologically complex motifs. They first revealed this distinction in a rationally designed colloidal analogue of water. They showed that this colloidal water model displays the well-known water thermodynamic anomalies as well as a liquid–liquid […]
