Explore the cross-section of single-walled nanotube bundles, the possible formation mechanisms, and the presence of C60 molecules within. Learn about the ideal conditions for C60 formation and the role of Ni, Co, and ferrocene. Discover how laser ablation of graphite leads to the formation of SWNT bundles.
