Fullerenes

Fullerenes – The word “Fullerenes” was given in honor of the American architect R. B. Fuller, who in 1895-1983 developed a project to create openwork domed structures that could be built using a combination of five and hexagons.
The third, recently discovered allotropic form of carbon, was named fullerene. Up to this point, only two of them were known – graphite and diamond. Fullerene is a microstructure of carbon atoms that form a spherical structure with a cavity inside.
There is a minimum number of carbon atoms that make up fullerene. However, there may be more of them – 70, 76, 78, 84, 90, 94, 96 etc. The more atoms of carbon material used in the construction of fullerene, the larger its volume of the cavity inside.
In the case when a fullerene is formed from carbon atoms, any other molecules or atoms can be “closed” in its cavity, as in a closed vessel.
The molecules trapped in the meteorites were found inside and found that they formed during their formation many hundreds of millions, and possibly several billion years ago. Thus, it became possible to study “preserved” samples of the substance that made up the Solar System during the formation of certain fullerenes.
