Our most recent work has been published in the journal of Nano letters. This time we introduced C60 fullerenes inside collapsed carbon nanotubes. The overfilling of the collapsed tubes allows a complete reinflation, where the C60 core shows a well defined crystalline structure. This work has been published as an open access, the file can be downloaded here. Hamid R.

Nano letters 15, 829–834 (2015)  AbstractWe examine a variant of so-called carbon nanotube peapods by packing C60 molecules inside the open edge ducts of collapsed carbon nanotubes. C60 insertion is accomplished through a facile single-step solution-based process. Theoretical modeling is used to evaluate favorable low-energy structural configurations. Overfilling of the collapsed tubes allows infiltration of C60 over the full cross-section of the tubes and consequent partial or complete reinflation, yielding few-wall, large diameter cylindrical nanotubes packed with crystalline C60 solid cores.
