An overlapping domain decomposition method (ODDM) is applied to calculate 3D eddy current field in nonlinear and anisotropic laminated core, and the Newton-Raphson iteration method(NRIM) is adopted in complex frequency domain. This method uses less calculation time in solving large scale electromagnetic problem with t…
The sp3C doped SiC superhard nanocomposite films had been deposited on stainless steel (SS) substrates at different temperature by electron beam-physical vapor deposition (EB-PVD). The sp3C doped SiC film was studied by grazing incidence X-ray asymmetry diffraction (GIAXD), and X-ray photoelectron spectroscopy (XPS).…
Bluecoke is a new type carbon product that prepared by low temperature carbonization process, which take lignite, long flame coal, not sticky and weak glue coal as raw material. At the same time tar and coke oven gas as by-products can be obtained. Two new technologies of Bluecoke production were introduced based on s…
Cupric hydroxide films with new hierarchical architecture were directly fabricated on copper substrate via a solution-immersion process at a constant temperature of 23°C. Stable superhydrophobic Cu(OH)2 surface was obtained after Cu(OH)2 films were modified with hydrolyzed 1H, 1H, 2H, 2H-Perfluorooctyltrichlorosilane…
Based on the “ex-situ” toughening concept, thermoplastic nylon (PA) nonwoven fabric with high porosity was chosen as the toughening layer, and the interlaminar toughened composites were fabricated via RTM process. Compression strength after impact (CAI) properties were investigated as well as the toughening mechanism.…
In this study, Al2O3 fiber composite papers with a certain strength and flexibility were prepared by pressure filtration. Microstructure and pore size of the composite papers with different density were investigated and thermal conductivities were measured by plane table thermo-conductivity meter at 600°C to 1200°C. T…
A new type of polymer nanoemulsion has been synthesized by molecular self-assembly technique. The emulsion particle size that can be clearly observed by CENT is less than 100nm. The results of these measurements support the idea that polyacrylate molecular segments assemble with polyester segments. Then based on the p…
Abstract This proceedings issue is a selective collection of papers presented at Symposium B “Amorphous Nanostructured Materials” which was conducted during the E‐MRS Fall Meeting 2011, Warsaw, Poland. The symposium program covered various aspects of amorphous materials science and technology, including the preparatio…
PURPOSE: To develop and validate an Optically Stimulated Luminescent (OSL) dosimeter for exposure control verification of x-ray projection mammography imaging systems. METHODS: The active detection element of the dosimeter is a strip of OSL material 3.0 mm wide, 0.13 mm thick and 30.0 mm long with an overlying aluminu…
A novel fabricated technique, by feeding two sets of different ZnO formulations powder in a die by parts, molded only once to produce layered structure(including layer A and layer B) low-voltage ZnO varistor. The samples are examined by using energy dispersive X-ray spectroscopy (EDS), electron probe microanalysis (EP…
We recently synthesized different composition polycrystalline Ho2+xTi2-xO7-x/2 (x=0, 0.4 and 0.67), which is derivative fluorite compounds known as and pyrochlore phases in Ho3O2-TiO2 phase diagram by using conventional solid state synthesis methods. The samples were irradiated with 400 keV Ne2+ ions at cryogenic…
As-cast AM60 magnesium alloy was solid dissolved with exercising different pressures to it. The microstructure of the products was characterized by optical microscope and X-ray diffraction. The mechanical properties of the products were investigated by microhardness tester and tensile testing. The results show that in…
Silicon (Si) quantum dot (QD) materials have been proposed for all-Silicon tandem solar cells. In this study, for the first time, high efficiency solar cells consisting of a sub-10-nm highly ordered and dense 2-dimensional (2D) array (one layer) of Si nanodisks (Si-ND) with a silicon carbide (SiC) interlayer have been…
Surface modification of carbon fibers(CF) by physicochemical methods directs an attractive approach for improvement of metal uptake from solutions. We investigated pretreatment of carbon fibers by HNO3 with different time on absorption of catalysts, which is related to the coverage of carbon nanotubes (CNTs) grown on…
During incubation of a constant volume of rat liver cytosol with an increasing quantity of mitochondrial protein in the presence of 3.3 mM MgCl(2), the binding of nucleoside diphosphate kinase (NDPK) from the cytosol to mitochondrial membranes is described by a saturation curve. The highest bound NDPK activity account…
Finite element simulations were conducted to investigate the influence of grain growth in the superplastic blow forming process. A microstructure-based constitutive model considering grain growth effects is proposed and used in the simulations. Also, a grain growth rate equation accounting for both static and dynamic…
Compound ceramic coatings with the main crystal phase of Al2TiO5 (as-coated samples) were prepared in situ on the surface of Ti-6Al-4V alloy by means of pulsed bi-polar micro-arc oxidation (MAO) in an NaAlO2 solution. The coated samples were calcined in argon and air at 1000 oC, respectively. The phase composition, su…
Próteses parciais fixas são empregadas na reabilitação da forma e função de dentes parcial ou totalmente comprometidos e devem permanecer permanentemente unidas aos remanescentes dentários. O material mais utilizado na confecção de próteses odontológicas é a porcelana feldspática. Contudo, ela apresenta propriedades m…
In order to aviod much high energy and CO2 generation. Microwave sintering (MS) is always carried out to prepare refractory. In this work，MS was proposed to sinter mullite composite. An insulation structure based on hybrid heating mode was well designed with the wall of high-aluminum refractory and the aided heaters o…
The effect of nitrogen-containing modifiers on the variations in the chemical composition of nickel alloys during electroslag refining and vacuum induction remelting has been discussed.
