Anomalies in, and Crystallization of Supercooled Water and Aqueous Solutions.
Abstract
This report summarizes research work performed under ONR auspices during the period 1978-1983. Thermodynamic studies of pure water and various aqueous solutions containing simple molecular second components such as H2O2N2H4 and formamide have been performed at temperature down to -120 C, in order to perform extrapolations to obtain properties of normal water, i.e. water free from anomalous structure fluctuations. Properties studied have been heat capacity, expansivity and compressibility. On certain of these solutions viscosity, and also dielectric relaxation studies have been performed. Spectroscopic measurements in both the far infrared, and the near infrared, have yielded information on vibrational modes and characteristic hydrogen bonding structures. All together these measurements have done much to elucidate the anomalous behavior of water in the supercooled regime.
