  • A three-parameter generalized equation is proposed for surface tension from the triple point to the critical point. This equation not only fits the data well but also is good for interpolation between the normal boiling point and the critical point. This equation is also good for extrapolation to the triple point. This equation has been tested using the surface tension of water from the triple point to the critical point. The constants of this equation obtained using orthobaric surface tensions are given for a number of compounds. The isobaric surface tensions determined at a pressure of 1 atm do notmore » differ significantly from the orthobaric surface tensions. Such data also have been used in obtaining equations from the triple to the critical point.« less
  • The proposed method uses Pitzer's acentric factor as a scaling factor for a linear interpolation/extrapolation of the surface tensions of 2 reference fluids and the Van der Waals one-fluid model to extend the pure liquid predictions to mixtures. Good agreement between experimental and predicted values of surface tension was obtained using only the data for the pure components. The agreement is better if a single binary interaction constant, independent of temperature and composition, is used in the mixture calculations. How the unknown surface tension of any given fluid can be obtained from the known properties of 2 (similar) reference fluidsmore » also is shown. 11 references.« less
  • A study was made of the electrocapillary phenomena in Cd- Bi alloys and of the surface tension of these alloys in vacuum at 450 deg C. Increase in concentration of bismuth in the alloy was shown to lower the surface tension of the latter both at the electrolyte interface and in vacuum. Calculations were made of the adsorption GAMMA /sub Bi/ at the alloy-electrolyte interface at the potential maxima of the electrocapillary curves, and it was shown that the shift of the maximum is linearly related to the surface concentrations of bismuth. Results of the surface tension measurements of themore » alloys in vacuum were examined in the light of the existing theories of the surface tension of binary mixtures. The surface tension isotherms were calculated according to the Zhukhovitskii formulas. Considerable divergence between experiment and the calculations was noted, and the possible reasons for the divergence were indicated. It was shown that the surface tension isotherms of the alloys in vacuum and at the electrolyte interface (at the electrocapillary curve maxima) are identical, showing the existence of approximately the same composition of surface layers of the alloys at both sides of the interface.

  • Matrix monotonicity is used to obtain upper bounds on minimum-error distinguishability of arbitrary ensembles of mixed quantum states. This generalizes one direction of a two-sided bound recently obtained by the author [J. Tyson, J. Math. Phys. 50, 032106 (2009)]. It is shown that the previously obtained special case has unique properties.
