LiNi0.8Co0.15Al0.05O2, as the cathode materials for lithium ion battery, were prepared from the precursors, Ni0.8Co0.15Al0.05(OH)2 which were synthesized by chemical co-precipitation method. LiNi0.8Co0.15Al0.05O2 particles are modified with AlF3 and AlPO4. Even though the initial discharge capacity of the coated LiNi0…
Ibuprofen (I) is the most widely used non-steroidal anti-inflammatory drugs (NSAIDs) has been synthesized in recent years. NSAIDs are the first choice of drugs that are normally used for the treatment of pain and inflammation. There are many methods for synthesizing of I but each one has some difficulties as raw mater…
The current research deals with an analysis of stress relaxation in nonwoven fabrics with different gsm values with a view to understand how these nonwovens behave under an applied stress for a given load over a constant period of time. An electronic stress relaxation tester is indigenously designed for this purpose w…
The efficient sensitization of the photoelectric effect in mixed compositions of poly(phenylquinoline)s (PPQ) with 2,1,3-benzothiadiazole (BTDZ) molecules is established. The introduction of 10 wt % BTDZ results in extension of the spectral sensitivity range of PPQ and an increase in the photosensitivity and photocurr…
In this paper, we propose a method for suppressing shaft voltage by modifying the rotor shape and the permanent magnets in interior permanent magnet type high voltage motors. The shaft voltage, which adversely affects the bearing by occurring bearing current, is induced by parasitic components and the leakage flux in…
An overview is given of the works on the creation of original high-precision oscillation methods for an integrated study of physicochemical characteristics and crystallization/melting of solutions and melts. Some experimental results are presented for viscosity and crystallization/melting in the region of stable and m…
The types of distributions of the structural and magnetic order parameters under torsion and pressure applied perpendicular to the “easy axis” of a ferromagnet are studied. It is found that these interactions cause two-sided single-phase and antiphase spatial amplitude modulations of the ordering parameters. Increased…
A version of the metal plasticity relaxation model based on a plasticity integral criterion with the characteristic relaxation time parameter is suggested. The dislocation concepts of metal plasticity together with the Maxwell model for a strongly viscous fluid are used to show that this characteristic relaxation time…
Experiments on leaching of borosilicate glass samples containing 10, 15, and 20 wt % simulated high-level waste (HLW) were performed at 20 and 90°C in hydrogen peroxide solutions. H 2 O 2 was used as a substance simulating products of underground water radiolysis. The leach rates and diffusion coefficients of the glas…
Abstract Mussel-inspired linking of titanium dioxide (TiO2) nanoparticles on a single-walled carbon nanotube (SWNT) was successfully attempted to provide a novel photocatalyst that shows enhanced and recyclable photocatalytic degradation of environmental pollutants such as Methylene Blue with ultraviolet and even with…
In order to improve the corrosion resistance and bioactivity of magnesium alloy coated by ultrasound micro-arc oxidation (UMAO), different content of n-TiO2 was added into silicate electrolyte. Electrochemical corrosion and simulated body fluid (SBF) soaking were conducted, and the surface morphology, phase structure…
The influence of modified nanosized magnetite (NSM) particles (magnetic microspheres coated with chitosan and magnetoliposomes) after a single intravenous infusion of their suspensions on iron metabolism in rats has been studied. Modern physical and chemical methods (X-ray fluorescence, dynamic light scattering, trans…
Extracting aluminum oxide from high-alumina coal fly ash are significant to make up for the inadequacy of bauxite resource in China. How to comprehensively utilize silica components in coal fly ash is a key technical question in industrialization for extracting of alumina from coal fly ash. Desilication of coal fly as…
In this paper we present the characteristics of leakage current at different shed of epoxy resin insulator under rain contaminants. The aim of this paper compared the leakage current characteristics under rain contaminant and dry test. Also it compared when used same and different sheds.
The band structures and optical properties of AB-stacked multilayer graphene are calculated using the tight-binding model and gradient approximation. For n L -layer AB-stacked graphene, there are excitation channels at both the low and middle frequencies. However, in the excitation spectra, n L ( n L − 1) peaks exist…
Fast and accurate fault classification in transmission lines is important for any protection devices. The present of extra transient signals cause to phase misclassification and malfunction of protection devices. Thus, it is crucial to provide a proper protection scheme that offer a good classification performance whe…
By minimizing a thermodynamic-like potential, we unbiasedly sample the potential energy landscape of soft and frictionless spheres under a constant shear stress. We obtain zero-temperature jammed states under desired shear stresses and investigate their mechanical properties as a function of the shear stress. As a com…
Cr-doped HMSs (higher manganese silicides), MnSi1.73 : Cr x (x = 0, 0.005, 0.01, 0.02, 0.03), were prepared by using a solid-state reaction and hot pressing. X-ray diffraction analysis and Rietveld refinement confirmed the synthesis of MnSi1.73. The Cr atoms were confirmed to be soluble in the HMS structure because th…
The increasing need for flexible electricity generation means that most components must perform under cyclic operating conditions. The multiplicity of generating options also means that defining a ‘typical’ cycle is difficult. Thus, in addition to the traditional hot and cold starts and stops, there are requirements f…
In recent years, increasing attention has focused on the residual-stress distribution in welded pipe, since residual stress is often responsible for the failure of welded pipe in industrial equipment. Residual stress σres appears in each step of welded-pipe manufacture, which relies on cold plastic shaping. Accordingl…
