Production of metal fragment ions by arc discharge.

Arc Discharge Instalation for Fullerene Production

Fullerenes, a new form of carbon, were discovered in 1985 [1] in graphite vaporization under inert gas at low pressure. Fullerenes have many properties different from either diamond or graphite. Potential applications include superconductors, sensors, catalysts, optical and electronic devices, polymer composites, high-energy fuels and biological and medical materials. But wide application of fu...

Structural transformation of graphite by arc-discharge

The formation of novel structures by the passage of an electric current through graphite is described. These structures apparently consist of hollow three-dimensional graphitic shells bounded by curved and faceted planes, typically made up of two graphene layers. The curved structures were frequently decorated with nano-scale carbon particles, or short nanotubes. In some cases, nanotubes were f...

Silicon etch with chromium ions generated by a filtered or non-filtered cathodic arc discharge

The pre-treatment of substrate surfaces prior to deposition is important for the adhesion of physical vapour deposition coatings. This work investigates Si surfaces after the bombardment by energetic Cr ions which are created in cathodic arc discharges. The effect of the pre-treatment is analysed by X-ray diffraction, Rutherford backscattering spectroscopy, scanning electron microscopy and in-d...

Production of Carbon Nanotubes and Carbon Nanoclusters by the JxB Arc-Jet Discharge Method

The Synthesis of Carbon Nano Tubes by Arc Discharge Method in Liquid media

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...
