The production of carbon nanostructures by ultrasonic treatment on high-oriented plane graphite
超声波处理高序石墨合成碳纳米结构

After the high oriented plane graphite has been treated by ultrasonic wave in water, by using high resolution transmission electron microscope and electron diffraction, we have found that carbon nanopolyhedron and carbon nanotube, which are similar to those found by means of arc discharge and laser ablation, have been produced. More importantly, we have also found a kind of novel carbon nano solid ball which consists of disturbed crystal lattice lines. In addition, we put forward a possible model to explain the growth process of these nanostructures.
