    Design and Manufacturing of a Machine for Producing Carbon Nanotubes
    (October University for Modern Sciences and Arts, 2020) Elattar, Mariam Magdy; Bagunaid, Mohamed Abdullah
    The production and industrial applications of Carbon Nanotubes (CNTs) are recently the main concern of research in nanotechnology. The special nature of carbon combines with the atomic flawlessness of single-wall CNTs to bless them with exceptional fabric properties, such as exceptionally tall warm and electrical conductivity, solidness, quality, and durability. It is the as it were component within the occasional table which bonds to itself in an expanded organize with the quality of the carbon-carbon bond. The delocalized pi-electron given by each iota is free to move about the full structure, rather than remaining with its benefactor iota, coming about within the to begin with known particle with metallic-type electrical conductivity. Additionally, an inherent warm conductivity higher than indeed jewel is advertised by the high-frequency carbon-carbon bond vibrations. In most materials, be that as it may, due to the event of absconds in their structure, the genuine watched fabric properties such as quality, electrical conductivity, and so on are debased exceptionally altogether. For illustration, high-strength steel regularly comes up short at as it were around 1% of its hypothetical breaking quality. In any case, CNTs accomplish values exceptionally close to their hypothetical limits owing to their atomic flawlessness of structure. This perspective is portion of the interesting story of CNTs. CNTs are cases of genuine nanotechnology: they are as it were approximately a nanometer in distance across, but are atoms that can be controlled physically and chemically in exceptionally valuable ways. They discover a mind blowing extend of applications in gadgets, materials science, vitality administration, chemical handling, and numerous other areas. The main goal of this project is to develop a complete design of an Arc Discharge (AD) machine for producing carbon nanotubes (CNT's) by using deionized water and extra pure graphite multiple electrodes 99.9% pure. The advantage of this design is to increase yield of CNTs within the experimental limitations, through the increase of the number of cathodes and anodes and by using an automatic feeding system for the electrodes, resulting in lower cost production.
