not to exceed 150 words): Since the discovery of Buckminster Fullerenes (C60), hours have been devoted to the study of this carbon nanoparticle. C60 has been investigated in such applications as photodynamic therapy of cancer, photovoltaic cells, semiconductors, and enzyme inhibition. Despite two decades of research, the biological effects of C60 remain a mystery. The intention of this study is...

A pseudo-potential that was successfully employed in an earlier study by the Compton group is used to describe the binding of a single electron to a C60 molecule to form C60 . Then, the interaction of a second electron with the C60 anion is treated in two manners. First, as performed in the earlier Compton study, a mean-field (i.e., Hartree–Fock) approach is used to estimate the C60 -to-C60 2 e...

Unimolecular decompositions of noble gas containing endohedral fullerenes as well as metallofullerenes were studied using tandem mass spectrometry techniques. Endohedral fullerenes do not lose the endohedral atom unimolecularly but fragment via the loss of C2 units. Kinetic energy release distributions were measured for the emission of C2 units from the positive ions of C60, Ne@C60, Ar@C60, Kr@...

C60 single crystals have been intercalated with CHCl3 and CHBr3 in order to expand the lattice. High densities of electrons and holes have been induced by gate doping in a field-effect transistor geometry. At low temperatures, the material turns superconducting with a maximum transition temperature of 117 K in hole-doped C60/CHBr3. The increasing spacing between the C60 molecules follows the ge...

From specific heat measurements in high quality H2@C60 samples performed over a broad temperature range, we obtain the smallest yet observed splitting of rotational energy sublevels of encapsulated single H2 molecules, 0.1-0.2 meV, in the nearly spherical potential well provided by highly isotropic C60 cages. Additionally, we find evidence of the quantized oscillation state of isolated H2 in th...

C60-based organic thin film transistors (OTFTs) with high electron mobility and high operational stability are achieved with (111) oriented C60 films grown by using template effects of diindenoperylene (DIP) under layer on the SiO2 gate insulator. The electron mobility of the C60 transistor is significantly increased from 0.21 cm V 1 s 1 to 2.92 cm V 1 s 1 by inserting the template-DIP layer. M...

Prior to the implementation of any new technology, possible environmental and health repercussions first must be researched. Fullerenes are to be produced soon on an industrial scale, with applications quickly following. To investigate the possible environmental impact of fullerenes, a C60-water suspension (nano-C60) was synthesized and then evaluated for cell-association and toxicity, using th...

We have investigated the changes in interfacial friction of toluene on mica and Ag(111) both in the presence and in the absence of interfacial C60 layers employing atomic force microscope (AFM) and quartz crystal microbalance (QCM) techniques. The lateral force measurements fail to detect C60 at the toluene/mica interface, presumably because the C60 is dislodged by the slowmoving probe tip. In ...

We report the measurement of conductance and thermopower of C60 molecular junctions using a scanning tunneling microscope (STM). In contrast to previous measurements, we use the imaging capability of the STM to determine precisely the number of molecules in the junction and measure thermopower and conductance continuously and simultaneously during formation and breaking of the molecular junctio...

Nanoconfined synthesized crystalline fullerene mesoporous carbon (C60-FMC) with bimodal pore architectures of 4.95 nm and 10-15 nm pore sizes characterized by XRD, TEM, nitrogen adsorption/ desorption isotherm and solid-state NMR, and the material was used for protein immobilization. The solid-state 13C NMR spectrum of C60-FMC along with XRD, BET and TEM confirms the formation of fullerene meso...
