Abstract The distribution, morphology and structure of carbon nanotubes and buckyonions produced from an arc discharge were investigated by means of scanning electron mi-croscopy and high-resolution transmission electron microscopy, The nanotubes and nanoonions were found to be located mainly near the porous region of the core in the deposited rods and the transition region between the growth ring-shaped graphite sheets. The tube bundles grew freely from carbon particles. Apart from the straight-line tubes, curved and bent tubes were also found. Studies on the structure of them showed that the carbon atomic sheets in the nanotubes displayed a stepped bending. Transverse sectional study predicted a helical structure of the carbon atomic sheets. In addition, the relationship between the number of pentagonal rings and cone angle at the tips of the tubes, as well as the mechanism of the formation of the steplike structure, were discussed.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
