The hydrolytic decomposition of dichlorodifluoromethane (CFC-12) on modified zirconium oxide surfaces and on charcoal has been studied. The reaction was carried out under flow conditions at 450 °C. Complete CFC-12 conversion was obtained by employing a molar excess of water in the gas phase which depresses the formati…
The effect of chain extender chemical structure on the physical and mechanical\nproperties of thermoplastic polyurethane/urethaneurea elastomers was systematically\ninvestigated.\nSeveral series of materials were synthesised using 4,4' -diphenylmethane diisocyanate\n(MDI) and poly(tetramethylene oxide) glycol (PTMG),…
We report the fabrication of a high-concentration Er-doped phosphate-niobate glass. The glass composition has been optimized for doping with erbium and for ion-exchange processing. Formation and modelling of planar ion-exchanged waveguides with silver and potassium dopants are also presented to confirm that this glass…
BaSno.9Sbo.1O3 /Ti electrodes were prepared by painting a slurry containing the oxide, synthesised by high-temperature solid state reaction, and Triton X-100 on titanium supports. The electrochemical behaviour of the electrodes was studied by cyclic voltammetry. From the voltammetric data the electrodes surface roughn…
A new method for the deposition of polypyrrole (PPY) thin films on a metal oxide surface through a grafting polymerization has been developed for the purpose of enhancing adhesion of the deposited PPY films to the substrates.
The a -axis electrical resistivity and the transverse magnetoresistance (aT-MR ) of stage-2 to 6 graphite intercalation compounds (GICs) have been measured in the temperature ( T ) range between 4.2 and 300 K and magnetic field ( H ) range between 0 and 7 kOe. The data are analysed together with the results of c -axis…
In order to examine the size effect of an interlacer, we made several interlacers with different diameters of yarn duct and air jet nozzle. For these interlacers experiments were carried out on the number of tangles and the distance between tangling parts, and yarn motion was also measured by means of an optical fiber…
Abstract This document proposes a nomenclature for aluminium silicon oxide nitrides. Introduction : Silicon and aluminium containing nitrides and oxide nitrides are widely studied by the chemical and ceramic community because of the interesting applications, in particular related to their (thermo-) mechanical properti…
We have systematically investigated the effect of microstructure on the magnetic properties of FebalCo49V1.9, FebalCo49V1.9Nb0.3, FebalCo27Cr0.6Ni0.6, FebalCo27Cr0.6Ni0.6C0.3 alloys in a temperature range of 20-700 °C. The effects of microstructure, the grain size, second phase precipitation, density of dislocation, a…
The PZT-based monolithic multilayer piezoelectric actuator (35 layers of piezo-ceramic, one layer 47μm thick) was fabricated by the tape-casting and the ceramic/internal-electrode cofiring method. The actuator shows large displacement under a low voltage (about 1μm displacement under 38V voltage). The static and dynam…
In creating new opportunities for fabric application, the uniaxial noobing process may find a role in producing 3D fabrics for certain technical uses other than the composite material (preform manufacture) for which it was particularly developed. However, to exploit the potential of this process, the present lack of i…
A building block of our experimental char-forming flame retardants is pentaerythritol phosphate alcohol or PEPA. We present examples of the synthesis of several PEPA derivatives, notably bis-PEPA carbonate (BPC) and bis-PEPA PEPA-phosphonate (BP3). The syntheses are complicated by steric hindrance to reaction, and the…
Ultra-violet (uv) light of wavelength 300 nm was irradiated on Fe-18Cr alloy during passivation in a deaerated 0.1 kmol·m−3 H2SO4 solution to modify the property of passive film. XPS analysis of the passive film revealed that uv light irradiation during passivation enhanced Cr enrichment in the oxide layer of the pass…
An important and not-obvious demonstration made in this work is that replacing a closed double-shell axial cylindrical shield with a similar but open-ended shield can lead to an increasing in not only the axial shielding factor, but in the residual uniformity as well. It is shown that a self-compensation of the residu…
Carbon dioxide reforming of methane on Ni/γ-Al2O3 catalyst was studied. A new 10 wt% Ni/γ-Al2O3 catalyst prepared by the liquid phase oxidation method (L10O) exhibited much higher activity as well as resistances to both sintering and coke formation during the reaction than the catalyst prepared by the conventional imp…
Polishing of a low dielectric constant fluorinated carbon blanket layer is performed by a magnesium oxide slurry. Although deep scratches are formed at the surface when polished by fumed silica and cellium oxide slurries, such scratches are not formed when polished by slurry. A tantalum nitride barrier layer is also p…
A spin cast film of polyetherimide (Ultem® 1000, GE Plastics) was analyzed by XPS using monochromatic Al Kα excitation. The measured atomic composition closely matched the expected stoichiometry of the polymer. Peak positions of the individual chemically shifted C 1s, O 1s, and N 1s components are reported. The result…
Correlation coefficients (CCs) between the mean atomic displacement parameters (B values) of the main-chain and the side-chain atoms in selected high-resolution protein structures are distributed over a broad range (0.5-1.0). The distribution of CCs is found to be related to the mean difference in B values of Calpha a…
