The effect of both the film-film interface and the SrTiO 3 interlayer on the magneto-optical and magnetotransport properties of La 2/3 Ca 1/3 MnO 3 -La 2/3 Sr 1/3 MnO 3 heterostructures, depending on the direction of external magnetic field, was studied. It is shown that the interface boundary makes a contribution cha…
With methyl vinyl silicone (MVQ) as the base rubber, filled with self-synthesized carbon coated aluminum nanoparticles, the high thermal conductive composite was prepared by using the method of mechanical blending. The effect of carbon coated aluminum nanoparticles on thermal conductivity and coefficient of thermal ex…
TiO2 has been loaded on cordierite porous ceramic to prepare the SCR catalyst carrier by using both APCVD and sol-gel method. The physical properties, SEM and SEM-EDX of the TiO2-cordierite carrier have been analyzed. The results showed that TiO2 loaded by APCVD method were of graininess shape and accumulated evenly.…
The process of particle impacting and contacting curved surface of vane was studied, and the characteristics of particle size, particle initial velocity and its impacting direction affect the stress of subsurface were analyzed by using ANSYS/LS-DANY software. It is shown that the interaction between particles and surf…
The Magnetite (Fe3O4) nanoparticles have been successfully synthesized through a solvothermal route by using FeCl36H2O and NH4HCO3 as the starting materials. The as-prepared products are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), superconducting quantum interference device magnetome…
Use of Low-chromium white cast iron as matrix, WC as reinforcement particles, in conditions of Quartz sand in ordinary water glass dry, non-vacuum, using self-made penetration compound was prepared by WC particles reinforced surface composite material with superior wear resistance, is 2.73 times that of high chromium…
The microstructure of Mn-Mo-Nb-B microalloyed steel was investigated under different cooling rates after austenitic deformation by using thermo-simulation test, hardness measurement, metallographic and TEM analysis. The experimental results show that most constituents are mixed bainite ferrite and granular bainite at…
The paper presents the manufacturing and the characterization of two novel devices on GaN/Si. The first device is a SAW structure for the GHz frequency range manufactured using nanolithografic techniques on GaN. Fingers and intedigits spacing 300nm wide have been successful developed in a single metal PMMA layer. An o…
The platinum (20% in mass) and ruthenium(10% in mass) catalysts supported on single-walled carbon nanotubes (SWCNTs) were prepared by liquid reduction method. The optimum technical conditions for purifying the SWCNTs were experimentally selected to be: nitric acid concentration of 4M, reaction temperature of 103°C and…
Single step growth of crystalline silicon on insulator (c-SOI) substrates based on rare earth oxide (REO) insulator layers are presented. Growth of crystalline REOs on silicon is possible due to their unique lattice matching to twice the lattice spacing of silicon. The single crystal nature of REOs make further silico…
On the investigations on the flexural properties,color stability and melting properties,the effects of treating ramie fiber with silane coupling agent on the anti-thermo-oxidative aging properties of high density polyethylene(HDPE)/ ramie fiber composites were studied.The results show that,treating the fiber with 3% c…
The electrochemical behavior of copper in various concentrations of NaHSO3 solution was investigated with linear polarization and cyclic voltametry technique at room temperature. The results showed that the concentration of bisulfite ions has noticeable effects on the behavior of copper. With HSO3 -concentration incre…
The physical parameters, which describe the relaxation phenomena occurring in both the bulk and contact regions of the systems under investigation, have been calculated using experimental curves of isothermal relaxation of polarization current in thin films of modified (As2Se3)100 − x Bi x . The relation between the c…
The mixed structures of bainite matrix, austenite and nodular graphite were obtained in nodular cast iron treated by controlled cooling and austempering in electric oven instead of nitrate salt bath. The relations between bainitic morphology and mechanical properties were investigated. Experimental results show that,…
A modified bio-polymers was prepared by melt reactive blending Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] with commercial chain extenders (ADR-4367). Steady shear and oscillatory measurements were employed to characterize viscoelastic properties of the chain extended bio-polymres. The results show th…
Interest in the behavior and resistance of structures for blast mitigation of high explosive charges is growing more and more. In this paper, the residual axial resistance of steel compressive members damaged by blast loading was precisely evaluated using the explicit-to-implicit finite element analysis method. The em…
SUMMARY Manganese doped biphasic calcium phosphate powders have been synthesized via sol-gel method. The powders are of nanosize and high crystallinity. Dense pure BCP and Mn-doped BCP ceramics were fabricated via uniaxial pressing using the sol-gel derived powders. The compacted discs were sintered in air atmosphere…
