Researchers at the Institute of Industrial Science at the University of Tokyo sifted through experimental data to probe the possibility that supercooled water has a liquid-to-liquid phase transition between disordered and tetrahedrally structured forms. They found evidence of a critical point based on the cooperative formation of tetrahedra, and show its minor role in water\u2019s anomalies. This work shows that water\u2019s special qualities\u2014which are essential for life\u2014originate predominantly from the two-state feature.<\/p>\n

Liquid water<\/a> is indispensable for life as we know it, yet many of its properties do not conform with the way other fluids behave. Some of these anomalies, such as water\u2019s maximum density at 4\u00b0C and its large heat capacity, have important implications for living organisms. The origin of these features has sparked fierce debates in the scientific community since the time of R\u00f6ntgen.<\/p>\n

Now, researchers at The University of Tokyo have utilized a two-state model that posits the dynamical coexistence of two types of molecular structures in liquid water<\/a>. These are the familiar disordered normal-liquid structure and a locally favored tetrahedral structure. As with many other phase transitions<\/a>, there may be a \u201ccritical point\u201d at which the correlation between tetrahedra takes on a power-law form, which means there will no longer be any \u201ctypical\u201d length scale.<\/p>\n","protected":false},"excerpt":{"rendered":"
