sentences:  There are multiple methods that were used in order to discover the fullerenes on the single wall carbon nanotube surfaces, each giving its own contribution to what is currently known about nanobuds.A few of these methods are ultraviolet-visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), and scanning tunneling microscopy (STM).To look even further into the functionality of CNBs and how the single wall carbon nanotubes interact with the fullerenes to produce the nanobuds, calculations were done.
