We report an investigation on the synthesis of Copper Oxide nanostructures via the Electro-Explosion of Wire method. Cu-CuO and Cu-Cu2O nanoparticles with mean particle size of 21.1 to 59.1 nm were synthesized by changing the applied current density and amount of used Tetra Methyl Ammonium Hydroxide as the surfactant. The X-ray diffraction analysis, field emission scanning ele...

This paper presents an approach to calculate the equivalent stray capacitance (SC) of n-turn of the helical flux compression generator (HFCG) coil with multi layer conductor wire filaments (MLCWF) in the form of rectangular cross-section. This approach is based on vespiary regular hexagonal (VRH) model. In this method, wire filaments of the generator coil are separated into many very small simi...

This paper presents the experimental results on explosion of copper wire at a discharge voltage of 9kV for the generation of Cu nanoparticles in nitrogen environment at different pressures. The current and voltage waveforms for different pressures of the nitrogen gas have been recorded by a current transformer and a high voltage probe. Nanoparticles generated by the electro exploded wire method...

electro-facies is a unit of the vertical sediments sequence on the wire-line logs that can be differentiated from the upper and lower units. for detection of the electro-facies interval in kangan and upper dalan formations in south pars gas field, wire-line log and core data analysis (wells a, b, c and d) were used. note, only core data analysis in well a were available. first, thin-sections st...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...
