Fullerenes materials have received wide attention due to their biomedical applications such as photodynamic therapy and magnetic resonance imaging [1]. The major limitations of realizing the practical applications of fullerenes are high cost and low production yield [2]. The arc discharge is well known technique for synthesis of carbon base materials. Here, we report the synthesis of fullerene ...

Single walled carbon nanotubes ~SWNT! produced by the anodic arc discharge over a range of constant background pressures of helium ~100–1000 Torr! were examined under a high-resolution transmission electron microscope, and a Raman spectrometer. It was found that the average SWNT diameter is about 2 nm and fairly independent of the background pressure. Analysis of the relative purity of SWNTs sa...

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. ...
