The paper presents the X-ray photoelectron spectra (XPS) of the valence band (VB) and of the principal core levels from the ( The XPS were measured with monochromatized Al Ka radiation in the energy range of 0-1400 eV at room temperature. The VB is located from 1.6 to 20 eV below the Fermi level. Experimental energies…
The corrosion inhibition of an aluminum alloy (UNS A96061) was evaluated in 3.5% sodium chloride (NaCl) solution for four different concentrations (250, 500, 750, and 1,000 ppm) of lanthanum chloride (LaCl3) and cerium chloride (CeCl3) inhibitors. The polarization resistance increased significantly with the addition o…
A three-dimensional finite element (FE) model for armchair, zigzag and chiral single-walled carbon nanotubes (SWCNTs) is proposed. By considering the covalent bonds as connecting elements between carbon atoms, a nanotube is simulated as a space frame-like structure. Here, the carbon atoms act as joints of the connecti…
Wood-plastic composites are probably one of the most dynamic sectors of today’s plastic industry. Although the technology is not new, there is growing interest in the new design possibilities offered by this marriage of materials. In the world, polystyrene (PS) is the third most utilized thermoplastic after…
The effects of nanoclay and foaming conditions on the foam morphology and mechanical properties of microcellular high density polyethylene (HDPE)–clay nanocomposite foams are investigated. Clay loadings of 0.5, 1.0, and 2.0 wt.% are used and the microcellular HDPE–clay nanocomposite foams are prepared by batch foaming…
The kinetics of KCN-catalyzed benzoin condensation of benzaldehyde in water and ethanol-water binary mixtures was investigated both under ultrasound at 22 kHz and without sonication. Thermodynamic activation parameters were calculated from kinetic data obtained at 35, 50, and 65 degrees C. Evidence that ultrasound can…
Polyamide‐6 is an engineering thermoplastic. It finds its application in electrical, mechanical, and automotive parts due to its very good processing qualities and excellent barrier properties to oils. Unfortunately, Polyamide‐6 is relatively high priced, has poor impact strength particularly when notched, poor dimens…
The accuracy of the prevailing geometrical models of the plain weft knitted fabrics is estimated and a more precise model for the use in computational modelling produced. The new proposed model is based on the assumptions of the ideal elastic yarn and the elastic energy minimization of the yarns composing the relaxed…
Ferromagnetic layer thickness dependence of anisotropic magnetoresistivities in Ta∕NiFe(t)∕IrMn (10 nm)∕Ta has been investigated for t=3, 4, 5, 7, 8, 10, 12, 15, and 20 nm by the method of anisotropic magnetoresistance and planar Hall effect. Our results revealed that the parallel and perpendicular resistivity compone…
In the present paper, a practical thermal treatment process has been introduced to stress relieve the iron powders in a soft magnetic composite. The composites were pressed and treated at different pressures and temperatures. Also, some of the samples were treated for various periods of time at 200°C. Density, electri…
The purpose of this article is to present the reader with a brief description of those characteristics of piezoelectric materials that directly influence imaging.
This paper considers high-frequency (200 kHz-1.0 MHz) losses in MnZn power ferrites and shows that none of the three well-known magnetic loss mechanisms (namely, hysteresis, classical eddy-current loss, and excess eddy-current loss) can account for the experimentally observed dependence of the loss on the frequency an…
Abstract Crystallization of semicrystalline polymer films during drying has a significant effect on the rate of solvent removal. Understanding and controlling the crystallization kinetics is important in controlling residual solvent levels and drying kinetics. The degree of crystallinity of the poly(vinyl alcohol) fil…
Abstract The mineralogical characteristics of authigenic palygorskite occurring with chlorite and illite in Miocene sediments in Linxia basin were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM). The XRD results suggest that t…
The identification of new corrosion inhibition systems remains dependent on experimentation for screening and characterization. One approach for the acceleration of this discovery process is through the use of high-throughput methods. This paper examines the measurement of surface copper enrichment as a method for the…
Development and testing of a bulk tungsten tile for the JET divertor, Hirai, T, Bondarchuk, E, Borovkov, A I, Koppitz, Th, Linke, J, Mertens, Ph, Neubauer, O, Panin, A, Philipps, V, Pintsuk, G, Sadakov, S, Steinbrech, R W, Schweer, B, Uytdenhouwen, I, Vaen, R, Samm, U, Sievering, R
Deuterium retention in the implantation-induced defects in polycrystalline tungsten has been studied. Deuterium was implanted with different energies and concentrations of retained D were analysed with secondary ion mass spectrometry and nuclear reaction analysis. Annealings were carried out at four pre-determined tem…
Abstract Numerous studies focus on the relationships between chemical composition and OH-band positions in the infrared (IR) spectra of micaceous minerals. These studies are based on the coexistence, in dioctahedral micas or smectites, of several cationic pairs around the hydroxyl group which each produce a characteri…
Abstract Luminescence properties of nominally pure and neodymium doped YVO 4 single crystals have been studied by means of time‐resolved luminescence spectroscopy technique. It was detected that, besides the main well‐known blue excitonic emission band near 2.8 eV, an additional UV emission band at ∼3.1 eV appears in…
This article describes liquid crystalline properties of the homologous series of 4-decyloxybenzylidene-4′-alkyloxyanilines. Based on the polarization microscopy (POM and TOA methods) and the calorimetric (DSC) measurements a rich polymorphism has been detected. Investigated compounds exhibit nematic, smectic A, smecti…
