More recently, fullerenes have been detected in outer space. C60 are spherical molecules about 1nm in diameter, comprising 60 carbon atoms arranged as 20 hexagons and 12 pentagons: the configuration ...

“For example, we can form thin films from them by vacuum ... A further key difference from other carbon nanomaterials, is that fullerenes are soluble in organic solvents, expanding the options ...

The abundance of naturally occurring fullerenes in carbon materials (for example, coal, rocks, interstellar media and even dinosaur eggs 10) therefore suggests a possible route for SWNTs to form ...
