“…Table 2 shows the average electrostatic field strengths of the samples. The values obtained were in the range 3.0 -4.5 ϫ 10 4 e.s.u./ cm 2 . These values are smaller than that of an ionic solid, TiO 2 (2.0 ϫ 10 5 e.s.u./cm 2 ) (18) because the ionic character of the chemical bond between a silicon atom and an oxygen atom in a silica structure is relatively weak among oxide materials.…”

“…Here a 30 two-state assumption has been used, such that µ vc is a linear combination of ice-like and liquid-like fractions. Such approximation has been used with success before (Etzler, 1983;Holten et al, 2013). However it is known that the structure of supercooled water represents an average of several distinct configurations (Stanley and Teixeira, 1980).…”

“…Early studies concluded that ordered water near immersed surfaces does not resemble a caltrate-like orientation of water molecules (Drost-Hansen, 1969). Rather, in the supercooled region the presence of structured low-density regions near solid surfaces (termed "ice-like") has been reported for different materials (e.g., Etzler, 1983;Yu et al, 2001;Michaelides and Morgenstern, 2007;Feibelman, 2010;Snyder et al, 20 2014). In this region Etzler (1983) parameterized the density and enthalpy of vicinal water as an ideal mixture of ice-like and bulk-like water.…”

Abstract.Heterogeneous ice nucleation initiated by particles immersed within droplets is likely the main pathway of ice formation in the atmosphere. Theoretical models commonly used to describe this process assume that it mimics ice formation from the vapor, neglecting interactions unique to the liquid phase. This work introduces a new approach that accounts for such interactions by linking the ability of particles to promote ice formation to the modification of the properties of water near the particle-liquid 5 interface. It is shown that the same mechanism that lowers the thermodynamic barrier for ice nucleation also tends to decrease the mobility of water molecules, hence the ice-liquid interfacial flux. Heterogeneous ice nucleation in the liquid phase is thus determined by the competition between thermodynamic and kinetic constraints to the formation and propagation of ice. At the limit, ice nucleation may be mediated by the dynamics of vicinal water instead of the nucleation work. This new ice nucleation regime is termed spinodal ice nucleation. Comparison of predicted nucleation rates against published data suggests that some 10 materials of atmospheric relevance may nucleate ice in this regime.

SynopsisThe membrane potential and permeability of NaCl were measured for six crosslinked poly(viny1 alcohol-co-itaconic acid) membranes having various water contents [0.25 5 H 50.83 H20 @/swollen membrane (g)] and interpreted by means of an equation derived from Schlogl's theory. Both results of the membrane potential and the permeability of the membranes having H2 0.34 could be satisfactorily interpreted by the theory. The permeability of NaCl in the membrane of H=0.25 gave, however, a n increasing tendency with the decrease of the upstream concentration lower than 0.04 mol/L. It was considered that the concentration dependence reverse to what was caused by the Donnan exclusion might be due to the concentration dependence of the thermodynamic partition coefficient in nonfreezing water of the membrane. By the equations thus derived the membrane potential and the permeability of NaCl in the membrane of H=0.25 were explained qualitatively. The mobility ratios of Na + and C1-and the effective charge density in the membranes were discussed. INTRODUCTIONTransport phenomena such as permeation and membrane potential of synthetic membranes have received a great deal of attention to elucidate the permeability of ions through biological and synthetic membranes.Several authors 1-5 investigated membrane potential and permeation of simple salts based on the theory of Teorel16 and Meyer and S i e v e r~.~ KObatake and co-workers8-11 derived equations from membrane potentials and salt flux considering the effective charge density. They investigated the mobilities and activity coefficients of K + and C1-in collodion-based polystyrene sulfonic acid membranes and found that the depression of mobility and activity coefficient of the counterions in the membranes could be represented by the empirical additivity rule known in polyelectrolyte solutions. Demisch and Pusch12 calculated membrane potential and resistance for binary and ternary electrolyte solutions employing Schlogl's eq~ati0ns.l~ The mobility ratios of the cations and the anions were estimated from membrane potential in weak and strong cation exchange membranes. Minoura and Nakagawa14 measured the membrane potential of poly(a-amino acid) membranes and found that the mobility ratios of Na+ and Li+ to K + in the membranes were larger than those in aqueous solution. Kinoshita et al.15 studied ionic salt permeabilities and membrane potentials of charged polypeptide membranes. They applied free volume theory to the temperature dependence of ionic permeability and concluded that the magnitude of ionic permeability depends on the free volume of the membranes, the effective charge density of the membranes, and the critical ionic diffusant EXPERIMENTAL MaterialsPoly(viny1 alcohol-co-itaconic acid) (PVA-IA) used in this investigation was kindly supplied by Kuraray Co., Ltd. and was employed after Soxhlet extraction with methanol for 12 h. PVA-IA has 1.3 mol % of itaconic acid, its saponification value is 97.7 mol %, and its degree of polymerization is 1750, respectively. Distille...
