In news:

Spherical fullerene molecules are referred to as buckyballs, after the first such molecule to be discovered (C60, buckminsterfullerene).

Challenge your students to build other fullerenes such as larger Buckyballs or Bucky tubes.
How do these models help support the idea that other fullerenes might exist.

This newly synthesized molecule is the smallest member of the family of closed-cage carbon molecules known as fullerenes.
All fullerenes incorporate exactly 12 pentagonal rings of carbon atoms, with some number of hexagonal rings filling in the rest of the structure.

A generalization of this morphology to large fullerenes is an Icosahedron5 .
The Shape of Bucky Onions
After the fullerene experiments there remains but a minor step to discuss conceivable (though hardly realizable) interference experiments with a conscious observer.
Decoherence: Basic Concepts and Their Interpretation
Recent experiments (Schon et al., 2001)demonstrating superconductivity in doped fullerene (C60) at 117K (with indications that higher temperatures may be attainable) indicates that certain organic structures may indeed promote quantum coherence.

Strikingly, enhancement of ferromagnetism has also been observed in disordered carbon (H¨ohne, Esquinazi, Han, Spemann, Setzer, Schaufuß, Riede, Butz, Streubel, and Hesse, 2004) and fullerene films deposited on Si substrates after proton irradiation (see section 3.2).
Induced Magnetic Order by Ion Irradiation of Carbon-Based Structures
We have checked this assumption irradiating carbon and fullerene films with thickness below 1 µm.

Makarova, Han, Esquinazi, da Silva, Kopelevich, Zakharova, and Sundqvist (2003) studied the magnetism in photopolymerized fullerene films by MFM.
Induced Magnetic Order by Ion Irradiation of Carbon-Based Structures
In contrast to the spot irradiation in HOPG (see section 3.1.2) no change in the topography has been detected after irradiation of the spots in the fullerene film.
Induced Magnetic Order by Ion Irradiation of Carbon-Based Structures
In contrast to the laser illumination on C60 film and proton irradiation in HOPG, proton irradiation of spots of micrometer size on the fullerene film do not produce appreciable changes in the topography.

Despite the discrepancies found from all the mentioned calculations, it is remarkable that these binding energies, relative to diamond, are considerably lower than that of the fullerene C60 (430 meV/atom)31 .
First-principles study of lithium-doped carbon clathrates under pressure
Graphite, for instance, is made of stackings of graphene planes, nanotubes from rolled graphene sheets, and fullerenes are wrapped graphene.
Modeling disorder in graphene
Twamley constructs a proposal for a QCA architecture based on Fullerene (C60 ) molecules doped with atomic species 15N and 31P , respectively, arranged alternatingly in a one-dimensional array.

Ti:sapphire source because of the large absorption cross-section and relatively low saturation intensity of fullerene (Table II). Hole-burning experiments in saturable media with relaxation times of several ms e.g. ruby, Er-fibre, require light sources with linewidths of just a few tens of Hz, at least for the probe.
Benchmark tests of slow light in saturable absorbers
In view of applications it is interesting that the analysis in indicates that the charge state of the fullerene impurities is electrically tunable, independently of that of the host carbon nanotube.
Charge transport through single molecules, quantum dots, and quantum wires
We as human observers do not seem to know the maximum number of the degrees of freedom in a system that we can still keep track of. A photon is certainly a quantum system from our point of view, a simple atom too, a C60 perhaps as well, albeit seeing quantum effects with fullerenes is not easy.
