利用原位高分辨透射电镜研究了开边多壁碳纳米管在高温下的稳定性。在实验中首次观察到壳间结构的形成，并将其归因于相邻同心壳之间的强大相互作用（所谓的唇-唇相互作用）。壳间结构的波动行为提示了碳原子在碳纳米管生长或收缩过程中可以通过壳间边缘进出的机制。
The stability of open edged multi-walled carbon nanotubes has been investigated by using in situ high resolution transmission electron microscopy at elevated temperatures. Formation of inter-shell structures was experimentally observed for the first time and attributed to a robust interaction between adjacent concentric shells (so-called lip lip interaction). The fluctuating behavior of the inter-shell structures suggests a mechanism by which the carbon atoms can pass in or out through the inter-shell edges during carbon nanotube growth or shrinkage processes.
