enhanced chemical vapor deposition (PECVD)5. This state of the art process, allows coating of substrates with various peptides, while controlling the uniformity of the coating regardless of the substrate and with lower costs. PECVD is a form of chemical vapor deposition where inert gas plasma is used to enhance reactivity of

Thermal diffusion, the process by which a multicomponent mixture develops a concentration gradient when exposed to a temperature gradient, has been studied in order to understand if its inclusion is warranted in the modeling of single-wall carbon nanotubes (SWNTs) synthesis by thermal chemical vapor deposition (CVD).
Hot-wire chemical vapor deposition (HWCVD ) has been employed for the continuous gas-phase generation of both carbon multi-wall and single-wall nanotube (MWNT and SWNT ) materials.Graphitic MWNTs were produced at a very high density at

Multi-walled carbon nanotubes (MWCNTs) were grown by plasma-enhanced chemical vapor deposition (PECVD) in a bell jar reactor. A mixture of methane and hydrogen (CH 4 /H 2) was decomposed over Ni catalyst previously deposited on Si-wafer by thermionic vacuum arc (TVA) technology.
Carbon Nanotubes (CNT) were synthesized by Chemical Vapor Deposition on Fe-Mo-MgO catalyst, by using ethanol (C 2 H 5 OH) as a carbon source and argon (Ar) as a carrier gas. The Reaction conditions are important factors that influence the yield and quality of carbon nanotubes.
This review article deals with the growth mechanism and mass production of carbon nanotubes (CNTs) by chemical vapor deposition (CVD). Different aspects of CNT synthesis and growth mechanism are reviewed in the light of latest progresses and understandings in the field.
