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.

采用水系统电弧放电结合超声喇叭合成了碳洋葱和碳纳米管。今年，为了实现这种反应场，新研制了一种新的体系。此外，采用高速摄像机拍摄了水系统电弧放电的高分辨率视频。在目前的结果中，还没有发现超声波的特殊作用会引起产品结构和性能的任何变化。然而，这一结果为阐明碳纳米离子和碳纳米管的形成机制提供了重要的信息。也就是说，埋弧放电系统中气泡的中心区域形成了碳离子和碳纳米管，而靠近气液界面的区域没有形成碳纳米管。此外，在埋弧系统中，将钛酸钡放入电极中，成功地合成了钛酸钡衍生的纳米管。
