Fullerene-fullerene collisions
Il Nuovo Cimento A, 1997The results of experimental studies of fullerene-fullerene collisions are presented and compared with molecular dynamics simulations and statistical models. The similarities with and differences to nuclear heavy ion collisions are discussed.

Medicinal chemistry with fullerenes and fullerene derivatives
Chemical Communications, 1999The study of the biological applications of fullerenes has attracted increasing attention despite the low solubility of the carbon spheres in physiological media. The organic functionalisation of fullerenes has helped solubilisation by covalent attachment of hydrophilic appendages.

Characterization of fullerenes and doped fullerenes
Synthetic Metals, 1993Abstract The results of a variety of experiments used to characterize fullerenes, metallofullerenes and alkali-metal intercalated C60 are reported. It is shown that differential scanning calorimetry and NMR characterization of the orientational phase transition in C60 provide sensitive means to assess the purity and crystallinity of fullerene samples.

The discovery and synthesis of fullerenes led to the hypothesis that they may be present and stable in interstellar space. Fullerenes have been reported in an impact crater on the LDEF spacecraft. Investigations of fullerenes in carbonaceous meteorites have yielded only small upper limits. Fullerene compounds and their ions could be interesting carrier

Journal of the American Chemical Society, 2005
Fullerenes were pyrolyzed by subliming them into a stream of flowing argon gas and then passing them through an oven heated to approximately 1000 degrees C. C(76), C(78), and C(84) all readily lost carbons to form smaller fullerenes. In the case of C(78), some isomerization was seen.

Fullerene collisions and clusters of fullerenes
International Journal of Mass Spectrometry, 2006Abstract Electron capture processes were studied in glancing collisions between multiply charged C60q+ ions and neutral C60 molecules at low collision energies where nuclear stopping dominates the interaction (typical energy: 10 keV; velocity v = 0.024 a .u . ).

Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths.

The most symmetrical C50 to C70 fullerenes with minimum numbers of pairs of adjacent pentagonal facets are considered in this paper. Like the well known C60 (35m) and C70 (10m2) fullerenes with no adjacent pentagonal facets, they appear to be stable in physical experiments and cause the visible peaks in mass spectra of carbon clusters produced by laser

Physical Review A, 2003
We have performed classical molecular-dynamics simulations of the fragmentation collisions of neutral fullerenes $({\mathrm{C}}_{24},$ ${\mathrm{C}}_{60},$ ${\mathrm{C}}_{100},$ and ${\mathrm{C}}_{240})$ with a hard wall. The interactions between the carbon atoms are modeled by a Tersoff potential and the position of each carbon atom at each time step ...

Superconductivity and Fullerenes
Materials Science Forum, 1998The conduction of electric current with no losses, expulsion of the magnetic field and appearance of macroscopic quantum phenomena are the characteristics which mark the superconductors as materials with extremely interesting properties. During the last several years great interest of scientists has been aroused by a particular class of superconducting
