The effective dielectric response ${\mathrm{\ensuremath{\epsilon}}}_{\mathit{M}}$ of a composite with aligned spherodial inclusions is calculated. Using the dipolar and the mean-field approximation (MFA) an analytical expression for ${\mathrm{\ensuremath{\epsilon}}}_{\mathit{M}}$ as a functional of the two-particle di…

X-ray photoemission measurements of high purity CuBr are presented. XPS studies of Cu compounds in this laboratory have been motivated by the need to identify species on chemically-etched high temperature superconductor surfaces [see R. P. Vasquez, M. C. Foote, and B. D. Hunt, J. Appl. Phys. 66, 4866 (1989)].

Measurement models have been applied to electrochemical impedance data collected at the corrosion potential for a copper disk rotating in alkaline- and acid-aerated 0.5 M chloride solutions. Several applications of measurement models for the interpretation of experimental impedance data are demonstrated. Corrosion is…

Electrical conductivities of aluminum nitride (AIN) doped with various ions of different sizes and valences have been measured at elevated temperatures. Grain conductivities of samples doped with large cations, obtained from complex impedance patterns, were much higher than those doped with small cations. The temperat…

Aluminum nitride/boron nitride composite was synthesized by using boric acid, urea, and aluminum chloride (or aluminum lactate) as the starting compounds. The starting materials were dissolved in water and mixed homogeneously. Ammonolysis of this aqueous solution resulted in the formation of a precomposite gel, which…

New preparative routes to the title compounds are reported in which the yields are substantially improved over previous methods. In one method, reaction of O 2 with a mixture of XC 6 H 4 CN 2 S 2 + Cl − and Ph 3 Sb leads to the products in 40–60% yield. In another, the reaction of the same salts with silylated amidine…
