“…Various reactive gas processes occur in the production of carbon-based material constituents such as nanotubes, amorphous carbon films, and even soot particles formed from combustion. Electron beam deposition, chemical vapor deposition, , pulsed arc discharge deposition, plasma deposition, − pulsed laser deposition, , laser ablation, combustion, , and ion beam irradiation are all processes that are used in the manufacture of carbon-based materials where the source of carbon is a reactive carbon-based gas. Because of the wide range of processing methods and conditions that can be used to fabricate carbon-based materials, their development can be time-consuming and expensive.…”
