| Research Abstract |
Carbon onions and carbon nanotubes were synthesized by arc discharge in water system combined with sonication horn. In this year, a new system were newly developed and fabricated to realized such reaction field. Furthermore, high speed camera was used to obtain high-resolution videos of the arc discharge in water system. In the current result, the special effect of the sonication to cause any change in the product structures and their properties has not been found. Nevertheless, this result gives important information to elucidate the formation mechanism of carbon nanooions and carbon nanotubes. Namely, the formation of carbon onoins and carbon nanotubes were taking place in the central zone in the bubbles appearing in the submerged arc discharge system, but not in the zone adjacent to gas-liquid interface. As additional result, nanotubes derived from barium tinanate was successfully synthesized as novel nanomaterials when barium titanate was put into the electrode in the submerged arc system.
