Alcaligenes faecalis AE122 that used poly(3-hydroxybutyrate) (PHB) as a sole source of carbon was newly isolated from a coastal seawater sample. The strain required seawater for growth on PHB as well as in a nutrient broth, in which seawater could be replaced by an appropriate concentration of NaCl. PHB depolymerase w…
Describes the FAST system, developed by CSIRO for quality control and assurance of fabrics. FAST, or Fabric Assurance by Simple Testing, consists of a series of instruments and test methods which are inexpensive, robust and simple to use. It measures properties which are closely related to the ease of garment making‐u…
The light scattering spectra of water in its normal and supercooled state were analyzed in the frequency range 0.3100 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$. It is shown that using the general idea of mode-coupling theory (MCT) one can describe consistently the temperature variations of both spectra and viscosity.…
A method for developing an accurate temperature-dependent dispersion model is described. It combines a room-temperature Sellmeier dispersion model with temperature-dependent refractive index measurements at a few wavelengths to predict the refractive index over a wide temperature and wavelength region. The method is a…

The mechanical properties of fluorophlogopite mica‐based glass‐ceramics, such as fracture toughness, flexural strength, and machinability, were investigated. It has been shown that toughening increments in the glass‐ceramics occurred by crack deflection and branching by crystals with a high aspect ratio. All the glass…
Anodic oxide films grown on Si in an aqueous solution have been characterized by in situ ac impedance techniques, and their behavior compared to thermal oxides. Mott‐Schottky analysis of oxide‐free p‐ and n‐type Si leads to doping concentrations which are in excellent agreement with independent data of conductivity me…
A simple reflection technique proposed by Teng and Man [Appl. Phys. Lett. 56, 1734 (1990)] as well as independently by Schildkraut [Appl. Opt. 29, 2839 (1990)] for measuring the electro-optic coefficients of poled polymer films is applied to measure the r33 values of both z-cut lithium niobate crystal and diazo-dye-su…
A new numerical mathematical method is presented for stack of lamellar gratings. It is based on expansion of the electromagnetic field in terms of the eigenfunctions of the Helmholtz equation. These eigenfunctions are in turn expanded in terms of sets of polynomial basis functions. It is shown that, for arbitrary pola…
Abstract An isotactic polypropylene homopolymer (PP) was added with 0 to 10000 ppm of γ-quinacridone, a β-crystal nucleator of PP. Flexural test specimens were injection-molded from the PP at cylinder temperatures of 200 to 320 °C and the structures and properties have been studied. The results can be summarized as fo…

The rate of crack growth by apparent intergranular decohesion of a statically loaded MnMoNiCr steel at 535–600°C in vacuum was measured using the d.c. potential-drop method. Slow-displacement-rate testing of notched tensile bars at the same temperatures in an inert atmosphere was also carried out. The steel had been a…
Electrochemical impedance spectroscopy (EIS) was used to measure the solid‐state diffusion coefficient of protons in nickel hydroxide films at room temperature as a function of state of charge (SOC). A model for the complex faradaic impedance of the nickel hydroxide active material is presented and used to extract the…

Thin films of V 1- x W x O 2 were deposited on glass and Si by dual-target sputtering and characterized by thin film X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS) and spectrophotometry. The relationship between x (0-0.026) and the phase transition temperature τ c (0-67° C) in the most applicabl…

For a quarter of a century X-ray diffraction in single crystals was unique in its ability to solve three-dimensional structures of proteins and nucleic acids at atomic resolution. The situation changed in 1984 with the completion of a protein structure determination by nuclear magnetic resonance (NMR) spectroscopy in…
Thin films of zirconium titanate on quartz glass were prepared using radio-frequency magnetron sputter deposition at various substrate temperature (Td from 25 to 450 °C). Crystallinity of the films sets in either at Td=400 °C or after annealing in air up to 650 °C. The refractive index showed monotonic increase with T…
A model is presented to calculate the rate of crack advance in the stepwise decohesion process which can result from the stress-induced penetration of a surface-adsorbed element into a solid, usually along grain boundaries. We call this process dynamic embrittlement. The model employs a diffusion equation containing b…
