Glassy water at cryogenic temperatures
For decades, physicists, physical chemists, and biologists have been tremendously intrigued by the unusual thermodynamic and kinetic properties of supercooled water. Theories have been proposed to account for the properties but these theories remain contentious for lack of experimental evidence. We investigate phase behaviors of water at cryogenic temperatures, especially high-density amorphous (HDA) ice and its glass-to-cryogenic liquid transition. The results will provide new insight into the physical origin of the anomalous properties of supercooled water.
