The effect of Zn substitution on the DC electrical resistivity, AC electrical conductivity and microstructure of V2O5 doped Zn(1-x)NixFe2O4 with x=0.0, 0.1, 0.2, 0.3, 0.4 (5 samples) were prepared by conventional ceramic technique has been investigated. The structural characterization of nickel-zinc ferrites were done…
The aim of the present work was to find out the sui table substitute material for ITO. Because the production of ITO (Indium tin oxide) is low and the cost is very high. So MgSnO 3 can be considered as suitable alternative. In this work, MgSnO 3 is prepared by spray pyrolysis method using suitab le molar concentration…
In this study the polymer composite specimen has been prepared by using polymer polyvinyl- pyrrolidone (PVP) and potassium iodide (KI) using double distilled water as the solvent. The main objective of the present work is to study microstructure, conductivity of the composite specimen for 10 to 40% KI and estimate it…
Effect of Cd, Fe and F dopants on the structural, morphological and optical properties of ZnO thin film deposited on glass substrate at a substrate temperature equal to 450 o C by spray pyrolysis technique have been investigated. X-ray diffraction spectra indicate that the films have polycrystalline nature with a hexa…
Modern electrical and communication technologies benefit from classical electrodynamics and electric circuits, both of which are based on the Maxwell's equations. Using the property of metric invariance in Maxwell's Equations, transformation optics has been proposed and achieves a rapid progress in the past decade. Tr…
The present study describes a low cost, easy procedural and easy to control technique for synthesis of highly pure silver nanoparticles (AgNPs) by ‘Electrochemical Route’ through pure metallic silver and evaluation of their antimicrobial activities. The electrochemical setup is developed indigenously to facilitate the…
This paper presents the theory, experiment setups and solution implementation of Hyperelastic Material Models in Finite Element Analysis to provide the description of material behavior that matches the conditions the product sees in real life. This can be a complex matter because the real life scenario may have the pr…
The purpose of the present work was to purify multi-walled carbon nanotubes (MWCNTs) produced by CVD using hydrochloric acid (HCl) and nitric acid () , HNO3 in order to remove the metal catalyst particles and amorphous carbon. The effect of acid treatment and sonication on the MWCNTs structure was obtained by X-ray di…
Angiogenesis is the formation of new blood vessels involves the migration, growth, and differentiation of endothelial cells, which line the inside wall of blood vessels. The process of angiogenesis is controlled by chemical signals in the body. These signals can stimulate both the repair of damaged blood vessels and t…
In this research work natural fiber reinforced polymer composites were prepared by reinforcing epoxy and vinylester resin with short areca leaf fibers. Different blend composites were prepared by varying weight fractions of areca leaf fibers. Their mechanical and physical properties were studied and compared as per th…
ZnxCd1� xSe QDs sensitized TiO2 photoelectrodes on FTO substrates have been prepared using an ionexchange route. The lattice parameters and band gaps of such ZnxCd1� xSe QDs were found to have linear and quadratic relationships with the Zn content (x). These TiO2/ZnxCd1� xSe films were further assembled to solar cells…
Experiments were conducted to study exhaust emissions of direct injection (DI) diesel engine with different levels of low heat rejection (LHR) combustion chamber such as i) ceramic coated cylinder head, ii) air gap insulated piston and air gap insulated liner and iii) ceramic coated cylinder head along with air gap in…
Welding defects can adversely affect the mechanical properties and performance of products in service. Therefore, a thorough understanding of these defects, how they occur, their severity, and remedies can guarantee high quality products and enhanced performance. The purpose of this review report is to investigate the…
Optimized approach for nanotwinned copper synthesis via electrodeposition technique is described. SEM, EBSD, XRD, and Nanoindentation tests of the synthesized layers were performed. The results of the tests demonstrate good surface quality and improved hardness.
Nanocomposites of polyvinyl alcohol- poly-acrylic acid- cobalt oxide nanoparticles have been prepared. The polymer matrix consisting of PVA0.85 and PAA0.15). The cobalt oxide nanoparticles was added to polymers with concentrations are (0, 2, 4 and 6) wt.%. The experimental results show that the absorbance of naoocompo…
Nanoparticulate drug delivery systems seem to be a viable and promising strategy for the biopharmaceutical industry. In particular of interest are polymeric nanoparticles have attracted the interest of many research groups and have been utilized in an increasing number of fields during the last decades. They have been…
This paper reports the tailoring of jute nanofibre reinforced composites for damping by the use of a suitable interlayer. The interlayer helped to improve the damping capacity of the composites, with a lowering in the stiffness values. In this work, jute nanofibres were used as reinforcement in epoxy resin matrix comp…
The concept of converting individual cells of the Diamond Double Bend Achromat (DBA) lattice into a modified 4-bend achromat with a new straight section for insertion devices (IDs) in the middle of the arc, grew out of earlier studies of low emittance MBA lattices*, and was motivated by the need for additional ID stra…
Complexes of Mn(II), Co(II), Ni(II), Cu(II), Ti(III), Cr(III), Fe(III), Zr(IV) and UO2(VI) with a Schiff base ligand derived from 2-hydroxy-5-methyl-3-nitroacetophenone and 2-hydroxybenzohydrazide have been prepared. The complexes have been characterized on the basis of elemental analysis, IR and electronic spectra, m…
In this paper the authors proposed a control algorithm for single phase active power filter to work under non stiff source. The method proposed compensate non linear load by improving the power factor to the desired value and also eliminate the harmonics under distorted Source voltage and source currents. A detailed s…
