Fullerenes synthesis by combined resistive heating and arc discharge techniques

Fullerenes synthesis by combined resistive heating and arc discharge techniques

The two main electrode techniques for fullerenes production; the direct arc technique and the resistive heating of graphite rod were employed in this work. One of the electrodes was resistively heated to high temperature and subjected to arc discharge along its length by the second graphite rod. Fullerenes solid were extracted from carbon soot samples collected from an installed arc discharge s...

Synthesis of Carbon Nanofibers by a Glow-arc Discharge

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...

Fabrication of inorganic molybdenum disulfide fullerenes by arc in water

Closed caged fullerene-like molybdenum disulfide (MoS2) nano-particles were obtained via an arc discharge between a graphite cathode and a molybdenum anode filled with microscopic MoS2 powder submerged in de-ionized water. A statistical study of over 150 polyhedral fullerene-like MoS2 nano-particles in plan view transmission electron microscopy revealed that the majority consisted of 2–3 layers...

Rigidization via Internal Resistive Heating

Rigidization of inflatable space structures via internal resistive heating requires carbon fiber reinforced material to consolidate and cure on-command. In terms of the spacecraft’s life, the rigidization process transforms a structurally weak “balloon” into a robust, stable design. Internal resistive heating provides an active approach for inducing permanent shapeholding and structural stiffen...
