With the aim of achieving a correlation between bimodal microstructure with the electrical conductivity of rare-earth-doped ionic conducting ceramics, spray dried samarium doped ceria (SDC) agglomerates with and without CNTs were employed as powder feedstock to synthesis SDC-based samples with bimodal microstructure t…
The redox properties of a Co(II)-Disulfiram complex has been examined using cyclic voltametry in different non-aqueous media such as dimethylsulfoxid (DMSO), dichlromethane(CH2Cl2) and mixed solvents at the surface of gold, pelatin and glassy carbon electrodes. It has been found that, this compound exhibits one electr…
The objective of this study is to characterize frayed fiber[1] under high resolution microscope to unveil fiber fraying. Based on observation with high resolution microscope, the classification of frayed fibers has been done to contribute to clarifying fiber fraying mechanism. One rectification on previous recognition…
Abstract An as-cast AZ31 magnesium alloy was investigated using light microscopy (LOM) and electron backscatter diffraction (EBSD) methods to quantify and describe the deformation mechanisms activated at high temperatures. Compression tests were carried out by means of a Gleeble®1500 device in the range of 320–500°C a…
We have investigated hall effect on YBa2Cu3-xMxO7-δ (M=Ni, Fe) bulk samples, with dopant amount 0 ≤ x ≤ 0.045 for Ni and 0 ≤ x ≤ 0.03 for Fe, with magnetic field (H=2.52, 4.61, 6.27 kOe) perpendicular to sample’s surface with constant current 100 mA. Our study shows that as both dopants increases, TC decreases and it…
The mechanism of this novel 3D diffraction radiation phenomenon is revealed. A rigorous theoretical solution is obtained for the problem of electromagnetic diffraction radiation of sub-wavelength holes array (SHA) excited by a point charge moving parallel to the one surface of SHA.
Successful construction and maintenance of NATM tunnel demands prediction, control and monitoring of support stress high accuracy. A magnetic anisotropy sensor is used for nondestructive measurement of stress on surfaces of a ferromagnetic material, such as steel. The sensor is built on the principle of the magneto-st…
This paper describes the details of synthesizing nano crystalline YBCO superconductor using a sol-gel combustion method and the effect of sol pH and sintering temperature on particle size was investigated. The sintering temperature was chosen 880°C and the samples were annealed at this temperature for 5 hours. The mor…
Calculation of the resonance frequency of cantilevers fabricated from an elastically anisotropic material requires the use of an effective Young’s modulus. In this paper a technique to determine the appropriate effective Young’s modulus for arbitrary cantilever geometries is introduced. This technique is validated usi…
La presente investigacion ha sido llevada a cabo con el proposito de estudiar el efecto de la deposicion de recubrimientos de TiN y ZrN obtenidos por deposicion fisica en fase vapor (PVD), sobre la resistencia a la corrosion de la aleacion de aluminio AA7075-T6. La resistencia a la corrosion fue evaluada a traves de m…

Two samples of jacketed Microtherm{reg_sign}HT were hydrostatically pressurized to maximum pressures of 29,000 psi to evaluate both pressure-volume response and change in bulk modulus as a function of density. During testing, each of the two samples exhibited large irreversible compactive volumetric strains with only…

The aim of the present work is to analyze the influence of temperature and minerals such ilmenite, Mg2Si, SiO2:MgO:Fe2O3, etc. on the decomposition and the racemization of the most simple chiral aromatic molecule, i.e. (R+)and (S-)-1phenylethanol (Pe-OH). To investigate this phenomena the minerals are deposited on the…
Effects of electromigration on microstructures of solder interconnections during electrical current stressing have been widely reported. However, a more profound understanding of the role of electron flow in the evolution and mechanical integrity of intermetallic layers is needed. Therefore, in this paper the effects…
pp. 1–12 A microfluorometric method has been developed to characterize lipid removal or ‘delipidation’ of the human hair cuticula during light exposure and chemical grooming processes such as oxidation (bleaching) and reduction. In the case of photochemical and chemical oxidation, lipid removal (‘delipidation’ of the…
A qualitative chemical analysis of three reference clay minerals, Mikawa montmorillonite, synthetic saponite and Nabeyama illite, was performed using a recently developed TEM-EDS set-up built around a microcalorimeter device that has a very high energy resolution. The spectrum obtained by the microcalorimeter EDS show…
Cascaded grating filters are proposed to cut the side lobes of silicon nanowire arrayed waveguide grating introduced by fabrication error. Numerical simulation shows that the crosstalk level can be improved by about 15dB.
We have discovered that if input grating coupler is used to excite SEW the generated wave is differed essentially from SEW. This wave is conventionally named “pressed wave” by us. We examine the evolution of wave field with distance from input grating coupler and compare that with analogous dependence for SEW. It is s…
Electrical as well as mechanical properties of electrically conductive adhesives can be modified by addition of different types of nanoparticles. It has been investigated if changes of the resistance of adhesive joints caused by thermal ageing will differ in dependence on the type of nanoparticles added into adhesives…
