Fullerene: Fullerenes
built 657 days ago
Country clubs are reserved for the rich and well-born; roughly speaking, this was ... the widespread impression of the exclusive domain of Fullerene research. Only select researchers with abundant scientific knowledge, high expertise, and sufficient funds to meet the high costs of Fullerene research were able to experiment with the valuable molecule.

The smallest possible fullerene is the dodecahedral C20, a shape consisting of 12 pentagonal faces and no hexagonal faces [1]. Larger, fullerenes have been found to exist in nature [2]. Nanotubes, nanohorns and buckybowls are other examples of fullerenes.

Diesel engines create low purity buckyballs (Fullerene structures named after Buckminster Fuller) and nanotubes due to the breakdown of the diesel fuel (a hydrocarbon from which the carbon comes to make the nanotubes), and always have. There is plenty of evidence that breathing emissions from trucks, buses and automobiles is not healthy but those same researchers have never found a link between carbon nanotubes and any negative effects.
