Ethanol has been found superior precursor for carbon nanotubes growth with lesser amount of amorphous carbon impurities. In this study, attention has been focused to determine the influence of Alcoholic Catalytic Chemical Vapor Deposition (ACCVD) reaction time on the growth and quality of CNTs via cobalt based catalyst. Effects of different reaction times on synthesis of CNTs were investigated by using characterization techniques like Scanning Electron Microscopy, EDX, X-Ray Diffraction and Raman Spectroscopy. Our results demonstrated that higher reaction times had significant enhancing effects on the yield of grown CNTs up to a critical reaction time and after that CNTs yield decreased. Quality of grown CNTs for 60 minutes was better than other reaction times. ACCVD reaction times also had a noticeable effect on the diameter of grown CNTs. Diameter of grown CNT has decreased continuously with the increase of reaction time from 60 to 150 minutes. The synthesized CNTs were a mixture of SWCNTs and MWCNTs..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
