Synthesis of single-walled carbon nanotubes by low-frequency bipolar pulsed arc discharge method

High-yield synthesis of single-walled carbon nanotubes by gravity-free arc discharge

Single-walled carbon nanotubes ~SWNTs! have been produced in high yield by the dc arc discharge technique under gravity-free conditions. Gravity-free conditions can reduce the convection flow of the buffer gas during the arc discharge, which results in the increase of high thermostatic volume around the arc flame. The yields of both the total soot and SWNTs in soot are significantly increased. ...

Localization of low-frequency oscillations in single-walled carbon nanotubes.

In the framework of the continuum shell theory, we analytically predict a new phenomenon: the weak localization of optical low-frequency oscillations in carbon nanotubes. We clarify the origin of the localization by means of the concept of the limiting phase trajectory and confirm the obtained analytical results by molecular dynamics simulations of simply supported carbon nanotubes. The perform...

Effects of Gravity and Magnetic Field on Production of Single-Walled Carbon Nanotubes by Arc-Discharge Method

Dispersion and characterization of arc discharge single-walled carbon nanotubes--towards conducting transparent films.

This study addresses a combination of a well-developed and mild dispersion method and high-quality arc discharge single-walled carbon nanotubes (SWCNTs) as starting materials. Thus, we advance in fabrication of transparent, conducting films with extraordinary low material loss during SWCNT processing. The starting material was characterized by means of thermogravimetric analysis, high-resolutio...

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...
