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…

Abstract
A simple model was developed which describes the effect of SiC submicrometer particles on the fracture toughness of alumina–SiC “nanocomposites.” This effect was attributed to the change in the fracture mode observed in alumina on adding SiC submicrometer particles, which was suggested to be a result of both matrix we…
The strength of alumina materials that had been subjected to varying degrees of densification was determined. Significant increases in strength were obtained for these materials even when there was minimal densification. For the most porous materials, the Weibull modulus values were similar but showed a significant in…
The < 2 µm fractions of Cheto (Arizona, USA) and Jelšový Potok (Slovakia) montmorillonites have been treated with 1 mol dm–3 H2SO4 for periods up to 6 h at 95 °C. The materials obtained were investigated by X-ray fluorescence (XRF), X-ray diffraction (XRD), infrared (IR) spectroscopy, and 29Si and 27Al magic-angle spi…
In the course of the mild methylation of 5,10,15,20-tetraphenyl-21-carbaporphyrin (CTPPH2) a novel isomer of N-methyl-5,10,15,20-tetraphenylporphyrin with an inverted N-methylated pyrrole ring, i.e. 2-N-methyl-5,10,15,20-tetraphenyl-21-carbaporphyrin (2-NCH3TPPH) has been synthesised. The protonation of 2-NCH3CTPPH pr…
Abstract The absorption of high kinetic energy by a small amount of material depends not only on the quality of the material but also on the structural design of the elements involved. Using a rapid response microbalance, we measured the tensions of radial threads in webs of the garden cross spider, Araneus diadematus…
