    Photostimulated anodic oxide film formation (1996)

    Notes: An explanation of the photostimulated formation of anodic oxide films is given in terms of the photoquenching of the internal electric field. A description of this phenomena is presented within the framework of the point defect model. For the stationary situation, concentration profiles for oxygen ion vacancies across the film, in the dark and under super band-gap illumination conditions, are derived. For the nonstationary case a transport model is presented that accounts for the observed linear dependence of the film thickness L(t) on (square root of)t for the photostimulated formation of anodic films on zirconium in (1 M) H3PO4. This model can be used to derive the product of the diffusion coefficient of the oxygen vacancies DO and changes in their concentration at the metal/film interface. With DO=5×10−17 cm2 s−1, a change in the m/f interfacial oxygen vacancy concentration of 3.4×1022 cm−3 is found. © 1996 American Institute of Physics.

    Measurement of pH in subcritical and supercritical aqueous systems (1992)

    Notes: Abstract The use of yttria-stabilized zirconia (YSZ) electrodes of the type Hg/HgO/ZrO2(Y2O3)/H+, for measuring pH in aqueous solutions at high subcritical (150〈T〈374°C) and supercritical temperatures (T〉374°C) is reviewed. The construction and operation of the YSZ and reference electrodes employed in these studies are described and their application in measuring the pH of a variety of technologically-important aqueous system is discussed. We show that the YSZ electrode is thermodynamically viable at temperatures into the supercritical region, and that it is a primary pH sensor in that calibration is not necessary, provided that the activity of water is known. However, highly accurate pH measurements at high subcritical and supercritical temperatures will require the development of more accurate reference electrodes.

    The thermodynamic viability of yttria-stabilized zirconia pH sensors for high temperature aqueous solutions (1988)

    Notes: Abstract The thermodynamic viability of the yttria-stabilized zirconia sensor (YSZS) [H2O, H+/ZrO2(Y2O3)/HgO/Hg] for the measurement of pH in high temperature aqueous solutions is evaluated by measuring potentials for this electrode and a conventional hydrogen electrode (HE) against a common reference electrode in a variety of solutions [0.01m H3PO4, 1m Na2SO4, 0.01m B(OH)3+0.01m KOH, and 0.01m KOH] at temperatures from 298.15K (25°C) to 573.115K (300°C). In order to compare theoretical and experimental potentials for the cell $$Pt/H_{2,} H^ + , H_2 O/ZrO_2 (Y_2 O_3 )/HgO/Hg (i.e.,HE/YSZS)$$ it was necessary to apply corrections for solution non-ideality (reflected in the activity of water) and salting in/salting out of hydrogen in solutions of finite ionic strength. Plots of the potential of the YSZS and the HE against a common external pressure balanced reference electrode (EPBRE) demonstrate the Nerstian response of the zirconia electrode, and an analysis of the cell HE/YSZS shows that the yttria-stabilized zirconia sensor is thermodynamically viable. Accordingly, the YSZS can be used as a primary standard for the measurement of pH. The data indicate that the precision of the YSZS for measuring pH in high temperature aqueous solutions is better than ±0.05 pH unit at 300°C (573.15K), provided that the activity of water and the isothermal liquid junction potential associated with the reference electrode are accurately known.

    Heats of solution and the influence of solutes on the temperature of maximum density of water (1974)

    Keywords: Water structure ; aqueous solutions ; heats of solution ; temperature of maximum density

    Notes: Abstract The influence of N,N-dimethylformamide, N,N-dimethylacetamide, 2-pyrrolidinone, N-methyl-2-pyrrolidinone, and N-t-butyl-2-pyrrolidinone on the temperature of maximum density (TMD) of water has been investigated. Heats of solution for these compounds and for diethylsulfoxide, tetramethylene sulfoxide, tetramethylene sulfone, dimethyl sulfoxide, and tetrahydrofuran in water at 23°C are also reported. These data, together with published TMD and heat of solution data for other solutes, are used to examine the relationship between the enthalpy change on dissolution of a solute in water and the effect of the dissolved substance on the structure of water as reflected by changes in the temperature of maximum density of the system.

    The influence of substituted alcohols on the temperature of maximum density of water (1976)
    Springer
    Journal of solution chemistry 5 (1976), S. 405-416

    Notes: Abstract The influence of various substituted (including halogenated) alcohols on the temperature of maximum density (TMD) of water has been investigated. Evaluation of the structural contribution to the shift in the TMD demonstrates that trifluoroethanol, hexafluoroisopropanol, and neopentyl alcohol are “structure makers”, whereas trichloroethanol and tribromoethanol are “structure breakers”. The results are discussed in terms of an excluded volume model.

    Notes: Abstract Enthalpies of solution of tetramethylammonium chloride in H2O+acetone, H2O+DMSO, and H2O+2,2,2-trifluoroethanol (TFE) are reported. The enthalpies of solution for the frist two solvent systems are positive for all compositions investigated, whereas for the H2O+TFE systemsΔHs becomes large and negative as the mole fraction of TFE is increased past 0.2. The enthalpy-of-solution data are rationalized on the basis of solvent structural effects and solvation.

    Notes: Abstract The effect of a homologous series of cyclic monohydric alcohols (C4−C8) on the temperature of maximum density of water has been examined. The structural contribution to the shift in the temperature of maximum density (TMD) is positive (increased structuredness) for alcohols up to C6 but becomes negative at C8. The behavior is compared with that of linear monohydric alcohols and Ω-diols.
