Anodic arc discharge supported by the erosion of the anode material is one of the most practical and efficient methods to synthesize various high-quality carbon nanostructures including nanotubes, graphene due to its relatively higher growth temperature and eco-friendly procedures. In order to increase the arc controllability of the as-synthesized products, we introduced a non-uniform magnetic ...

The electrical resistance of mats of single-wall carbon nanotubes (SWNTs) is measured as a function of mat temperature under various helium pressures, in vacuum and in atmospheric air. The objective of this paper is to study the thermal stability of SWNTs produced in a helium arc discharge in the experimental conditions close to natural conditions of SWNT growth in an arc, using a furnace inste...

a simple, inexpensive and one-step synthesis route of ag-tio2 nanoparticles by arc discharge method isreported. the resulting nanoparticles were characterized using x-ray diffraction and scanning electronmicroscopy. x-ray diffraction patterns demonstrate dominance of rutile to anatase phase in tio2 andformation of silver metal on tio2 after arc discharge process. scanning electron microscopy im...

In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes...

Arc discharge is one of the most efficient and environmental friendly method to synthesize Single Wall Carbon Nanotube (SWCNT). However, due to the ultra-fast synthesis procedure, localization of the SWCNT synthesis in an arc discharge plasma volume in situ has been a long standing problem. This relates to the ability of controlling volumetric synthesis of nanostructures in plasmas in general. ...

following our interest in reaching for a molded rubber article with possible detergent contact applications, durable silver nanopowder (agnp) is synthesized by arc discharge, then mixed with varying ratios of ethylene propylene rubber (epr), affording novel agnp@epr nanocomposites. x-ray diffraction (xrd) patterns of agnp as well as agnp@epr show no trace of impurity, while scanning electron mi...

Abstract. Since electromagnetic (EM) noise resulting from an arc discharge disturbs other electric devices, parameters on electromagnetic compatibility, as well as lifetime and reliability, are important properties for electrical contacts. To clarify the characteristics and the mechanism of the generation of the EM noise, the current noise up to GHz band frequency generated by slowly breaking c...

This work was focused on the studies of gliding arc plasma discharge with respect to its use in decomposition of volatile organic compounds and on the solid phase microextraction analysis of the discharge products. The simple one stage gliding arc reactor was used for these experiments. The applied voltage generating the discharge was varied in the range of 3.5 – 4 kV, the dry air and its mixtu...
