It has long been recognized that the quality of yarn depends on the performance of the processes during spinning. This work relates to evaluating the opening action of blow room and aims to develop the openness tester for measuring the openness of fibrous assembly based on the image processing technique. A sequence of…
US company PMC Polymer Products Co has introduced a line of flame retardant masterbatches free from decabromodiphenyl ether (deca-BDE). The launch follows the recent announcement that deca-BDE is to be phased out from all applications in the USA by the end of 2013 [ ADPO , February 2010].
This research involves study effect of halogen ions presence in 0.2M sodiumsulphate on the corrosion of brass at room temperature (30oC). Three concentration ofhalogen ions (Fˉ, Clˉ, Brˉ, and Iˉ) were used 0.1, 0.2, and 0.3 M. The different incorrosion parameters before and after added the halogen ions interpreted and…
Abstract In this work, we report a novel electrochemical technique to prepare band gap engineered IV–II–VI type ternary solid solution system of Pb x Cd 1– x Se. This technologically important material is prepared using this method for the first time. We have used a self sufficient modified electrochemical cell made u…
The heat propagation at room temperature in the heterostructure – polycrystalline diamond film deposited on a silicon substrate has been investigated by the pulse photothermal method. A thin In film evaporated onto the diamond was used as a thermometer. The experimental response was compared to that calculated by the…
By studying the pressure dependence of the fragility, it is expected that new horizons will open to understand the relaxation behaviour of supercooled liquids. However, as far as the authors are informed, no study has been performed on pressure dependence of the fragility in bulk metallic glass forming systems. In the…
A non-contact magnetoelastic torque transducer consisting of a non-magnetic shaft with a portion of its length coated with a magnetostrictive material is studied. A phenomenological theory is developed for predicting the magnetic field of the transducer as a function of coating properties, residual strain, and applied…
Antiepileptic Effects of Silk-Polymer Based Adenosine Release in Kindled Rats. Szybala C, Pritchard EM, Lusardi TA, Li T, Wilz A, Kaplan DL, Boison D. Exp Neurol 2009;219(1):126–135. Pharmacotherapy for epilepsy is limited by high incidence of pharmacoresistance and failure to prevent development and progression of ep…
Abstract. Hexagonal Co-containing Z-; Y- and M-type ferrites are used as soft magnetic materials for multilayer inductors for operating frequencies up to 3 GHz. Co2Z-type Ba3Co2Fe24O41, iron excess Ba3Co2-yFe24+yO41 (0 y 0.8) and Ba3Co2-CuxFe24O41 (0 x 1.0) ferrites have their stability intervals between 1260-…
Laser full-penetration welding of novel in situ TiB2 particulate reinforced ZL101 composites was studied using three different welding velocities synchronized with proper laser power. The optimal welding process parameters for laser full-penetration welding of in situ TiB2 reinforced ZL101 composites were suggested. T…
At B3LYP/6-31G* and MP2/6-31G* levels, the bond dissociation energies(BDEs) of O—NO2 bond in four nitrates such as n-propyl nitrate(NPN), isopropyl nitrate(IPN), 2-ethylhexyl nitrate(EHN), and tri-ethylene glycol dinitrate(Tri-EGDN) were calculated. The thermal decomposition characteristics of NPN, IPN, EHN, and Tri-E…
Frequency and temperature dependence of dielectric constant ( ) a n d d i e lectric loss ( ) i n pure epoxy resin and polymer composites with glass fiber are studied in the frequency range 40Hz-110 MHz and in the temperature range (25-150) 0 C.The experimental results show that and increased with the addition of glass…
Electrostatic self-assembled films were successfully prepared by alternating deposition of SiW12O40(4-) and a biferrocenyl-containing hemicyanine derivative on quartz or indium-tin-oxide coated glass substrates. The films were characterized by UV-visible absorption spectroscopy and cyclic voltammetry.
The visible luminescence mechanism of ZnO is an important but controversial problem. In this paper, we report the structural and optical properties of Mg-doped ZnO nanoparticles (approximately 3-4 nm) synthesized via the sol-gel method. X-ray diffraction (XRD) analysis and absorption spectra observations revealed that…
Abstract One challenge facing green tire technology is to achieve good silica hydrophobation/dispersion within the polymer matrix without a detrimental increase in the rubber compound’s viscosity during compounding. This phenomenon is well known to be induced by premature and unwanted coupling and/or crosslinking of t…
A new phenomenological approach is proposed to describe the crystallization kinetics in solid solution-aqueous solution binary systems. The phase diagrams, equilibria, and quasie-quilibria are considered within this approach. The crystallization kinetics near the true equilibrium and the crystallization features at la…
The authors investigated the behavior of an electric field near a junction composed of metal, dielectric, and vacuum. By using the two-dimensional model of the junction, the authors calculated the electric field near the junction as a function of configuration. For the triple junction of metal-vacuum-dielectric, the e…
The synthesis of 5-oxo[1,3]dithiolo[4,5-d][1,3,2]dithiazol-1-ium chloride 1a from easily available zink chelate, TEA[Zn(DMIT)2], has been developed; salt 1a has been converted to the first representative of [1,3]dithiolo[4,5-d]dithiazolyl radical, which was identified by EPR and CV data.
The set of Hill yielding condition equations is transformed for a metal with a sharp texture caused by its hexagonal close-packed lattice. In the presence of such a texture, the number of the parameters of the anisotropy of properties and, hence, the number of experiments required to determine them are shown to decrea…
We will report the results of our recent inelastic neutron scattering study on β-US 2 . This compound shows a semi-metallic or narrow gap semi-conducting behaviour at room temperature. A clear exponential up-turn of the resistivity in the order of ~10 6 Ωcm has been observed below 100 K. We found a sharp inelastic pea…
