The time function of the Erying reaction rate theory of insulation life is modified to demonstrate a physical origin for temperature threshold. Various mechanisms by which trapped charges may be involved in degrading the polymer are examined, and incorporated into the life model through an alteration to the free energ…
Flashover mechanisms of silicone rubber used for outdoor insulation is presented and experimentally proven. A hydrophobic surface of silicone rubber wets and accumulates contaminants differently compared to conventional porcelain and glass insulators. This suggests that the flashover mechanism of silicone rubber insul…
β″-(bedt-ttf)4[(H2O)Fe(C2O4)3]·PhCN [bedt-ttf = bis(ethylenedithio)tetrathiafulvalene] is a superconductor [Tc 8.5(3) K]; from 9–300 K its magnetic susceptibility is dominated by the high-spin FeIII and obeys the Curie–Weiss law (C= 4.375 emu K mol–1, θ=–0.2 K).
Homogeneous Y‐Si‐O‐N glasses containing 15 or 20 eq% nitrogen (N) were prepared from compositions with Y/Si ratios in the vicinity of that of the lowest eutectic point on the Y 2 O 3 –SiO 2 phase diagram. The liquidus on the phase diagram shifted toward lower temperatures by incorporation of N. The density, the elasti…
To understand better the origin of protein rejection observed with surface-bound poly(ethylene oxide) (or PEO), we have measured fibrinogen adsorption for a series of linear and branched, low-molecular-weight PEOs bound to solid polystyrene surfaces. The results show that a dependence on molecular weight is found belo…
The relative time scales at which semivolatile gas and particle PAH approach equilibrium under both moderate and cool temperatures were investigated. Combustion particles were added directly from a diesel car and a wood stove to a 190 m^3 outdoor Teflon film chamber. The rate of migration of a gas-phase semivolatile P…
The morphologies of the small proteins Zn2Cd5-metallothionein, cytochrome c3 and β-lactamase I immobilized inside carbon nanotubes have been studied by high-resolution transmission electron microscopy (HRTEM); single protein molecules and their associated forms were clearly observed inside the central cavity and a sig…
A simple and efficient method for the estimation of iron loss under any nonsinusoidal voltage without multiple zero crossings (i.e. without minor hysteresis loops) is proposed. This method is based on the loss separation model, where iron loss is decomposed into hysteresis, classical and excess loss components. The vo…
High surface area, mesoporous zirconium(IV) oxides may be prepared by controlled heating of a surfactant–zirconium(IV) oxide composite in which the surfactant acts as a combined drying-control and scaffolding agent.

It is essential to understand in which way and how much energy is transferred from the milling tools to the powder in the milling process. We have attempted to quantify the energy transferred per impact and per unit of mass in a planetary mill assuming that collision is the dominant energy transfer event. Further, att…
The stoichiometry, stability and polymorphism of the perovskite-related solid solutions, Li0.5 – 3xRE0.5 +xTiO3: RELa, Nd, has been studied. For both series, the data are presented in the form of a temperature vs. composition phase diagram. Unit cell data for the different polymorphs (three in the La system, four in t…

Experimental results show that the contamination performance of silicone rubber composite insulators is better than porcelain insulators. This is attributed to the hydrophobicity of the silicone rubber. This suggests that the flashover mechanism of these insulators is different. This paper experimentally investigates…
The ligand 2,6-bis(1′-ethyl-5′-methylbenzimidazol-2′-yl)pyridine (L5) reacts with lanthanide perchlorate in acetonitrile to give the mononuclear triple-helical complexes [Ln(L5)3]3+(Ln = Eu, Gd or Tb). The crystal structure of [Eu(L5)3][ClO4]3·4MeCN has been determined, which shows three unco-ordinated perchlorate ani…
