  Fullerene - Wikipedia, the free encyclopedia
Since buckminsterfullerenes have a similar shape to that sort of dome, the name was thought to be appropriate.
Fullerenes are similar in structure to graphite, which is composed of a sheet of linked hexagonal rings, but they contain pentagonal (or sometimes heptagonal) rings that prevent the sheet from being planar.
In the Walt Disney film, Flubber, the formula and molecular structure of the Flubber was modeled after buckminsterfullerene.

 The Discovery of Fullerenes, and Their Potential Applications
The facet of buckminsterfullerene and the related fullerenes that one first must look at is their discovery.
Buckminsterfullerene and the rest of the fullerenes, except for buckytubes, had three co-discoverers, while buckytubes themselves were discovered by Sumio Iijima, a scientist working at NEC Corporation's Fundamental Research Laboratories in Japan.
The story of the discovery of buckminsterfullerene is a long and complex one, and before one can look at the big historical moment of discovery by Smalley, Kroto, and Curl, one must look further back in time to the summer of 1967, which just happened to be Canada's centennial.

 MAKING.HTML
Most molecules absorb in the Infra-red (IR) and the number of absorptions is dependant on the number of atoms in the molecule and how symmetrical the structure of the molecule is. In general an N atom molecule will have about 3N absorptions in the IR.
However because of the unique symmetry of Buckminsterfullerene, C60 has just 4 IR absorptions.
This incredibly simple spectral fingerprint for C60 made IR spectroscopy a particularly effective method by which to probe for C60 in the arc made materials.

 The Naming of Buckminsterfullerene
H.W. Kroto said that the newly discovered carbon cage molecule was named buckminsterfullerene "because the geodesic ideas associated with the constructs of Buckminster Fuller had been instrumental in arriving at a plausible structure" [1].
Buckminsterfullerene was discovered by chemists who were not looking for what they found.
This is exactly what the chemist has discovered to be true." Baggott goes on to describe how Fuller had derived his vector equilibrium (cuboctahedron, in conventional geometry) from the closest packing of spheres of energy.

Yet buckminsterfullerene was discovered only in 1985, by the British chemist Harry Kroto and Americans Rick Smalley and Bob Curl.
Although it was found by serendipity, buckminsterfullerene is perhaps the ultimate 'designer' molecule.
The story of its discovery appealed to me not only as a lapsed chemist (whatever did happen to that Ph D?) but as a follower of architecture and design—subjects which turn out, possibly not entirely coincidentally, to be interests of Kroto's as well.

 Amat Containment
Other varieties include laser-pressure containment, utilizing 6 split beams of laser light striking the amat, keeping it pinned in the target zone, or buckminsterfullerene sequestered amat.
Buckminsterfullerene has a repulsive effect in its core called an 'electron repulsion zone' which keeps atoms (whose outermost layers are, of course, electrons) centered within the cavity.
With sufficient force, the buckminsterfullerene can either crack or inertially lose containment of the amat, leading to a matter/antimatter reaction that can easily be chained through other buckminsterfullerenes.

 Carbon - Wikipedia, the free encyclopedia
Structure: each atom is bonded trigonally to three other atoms, making a 2-dimensional network of flat six-membered rings; the flat sheets are loosely bonded.
Structure: comparatively large molecules formed completely of carbon bonded trigonally, forming spheroids (of which the best-known and simplest is the buckminsterfullerene or buckyball).
The structure is somewhat similar to the structure of graphite.
