主　　题：Multi-walled carbon nanotubes lip lip interaction in situ transmission electron microscopy 

摘      要：The stability of open edged multi-walled carbon nanotubes has been investigated by using in situ high resolution transmission electron microscopy at elevated *** 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 fl uctuating 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.
