TL;DR: In this article, two amorphous fullerenes, TPA-PCBM and MFPCBM, have been developed as efficient electron acceptors to induce a highly stable morphology of active layer in polymer photovoltaic devices.
Abstract: Two amorphous fullerenes, TPA-PCBM and MF-PCBM, have been developed as efficient electron acceptors to induce a highly stable morphology of active layer in polymer photovoltaic devices. The power conversion efficiency (PCE) of devices using both materials show no degradation, even after 10 h annealing at 150 °C.

TL;DR: Graphitic nanofibers, which include tubular fullerenes (commonly called 'buckytubes'), nanotubes and fibrils, which are fucntionalized by chemical substitution, are used as electrodes in electrochemical capacitors as discussed by the authors.
Abstract: Graphitic nanofibers, which include tubular fullerenes (commonly called 'buckytubes'), nanotubes and fibrils, which are fucntionalized by chemical substitution, are used as electrodes in electrochemical capacitors. The graphitic nanofiber based electrode increases the performance of the electrochemical capacitors.

TL;DR: In this article, the atomic structure and formation mechanism of carbon (C) and boron nitride (BN) fullerene materials were investigated by high-resolution electron microscopy, energy dispersive spectroscopy and electron energy-loss spectrography.
Abstract: Carbon (C) and boron nitride (BN) fullerene materials (clusters, onions, intercalation, nanopolyhedra, nanotubes and nanocapsules) were synthesized by polymer pyrolysis, chemical reaction, arc-melting and electron-beam irradiation. Atomic structure and formation mechanism were investigated by high-resolution electron microscopy, energy dispersive spectroscopy and electron energy-loss spectroscopy. Fullerene clusters and atomic clouds (atom hopping) were formed on the surface of the C and BN fullerene materials. They provided angular and spherical nanocage structures which consist of four-, five-, six-, and seven-membered ring bonding. Detection possibility of doping atoms in metallofullerene was discussed. Included clusters showed some crystallographic relationship with {001} layers of C and BN fullerene materials, and a structure model was proposed. Photoluminescence and magnetic properties of C and BN nanocapsules were measured, which showed higher energy shift of luminescence and superparamagnetism. The present work indicates that the new C and BN fullerene materials with various atomic structure and properties can be produced by various synthesis methods, and a guideline for designing the C and BN fullerene materials is summarized.

TL;DR: A model that postulates a mixture of scroll-shaped and concentric, cylindrical graphene sheets is proposed to explain the microstructure of graphite multishell nanotubes grown by arc discharge and explains clustering in a natural way.
Abstract: A model that postulates a mixture of scroll-shaped and concentric, cylindrical graphene sheets is proposed to explain the microstructure of graphite multishell nanotubes grown by arc discharge. The model is consistent with the observed occurrence of a relatively small number of different chiral angles within the same tubule. The model explains clustering in a natural way and is consistent with the observation of asymmetric (0002) lattice fringe patterns and with the occurrence of singular fringe spacings larger than c/2 (c is the c parameter of graphite) in such patterns. Anisotropic thermal contraction accounts for the 2 to 3 percent increase in the c parameter of nanotubes, compared with bulk graphite, but is too small to explain the singular fringe spacings. The model also explains the formation of multishell closure domes. Nucleation is attributed to the initial formation of a fullerene "dome."

TL;DR: In this article, the first self-assembled monolayer (SAM) of C[sub 60] was reported, its spectroscopic and electrochemical characterization, and initial chemistry with respect to its further modification.
Abstract: The authors report the first self-assembled monolayer (SAM) of C[sub 60], its spectroscopic and electrochemical characterization, and initial chemistry with respect to its further modification. The latter demonstration is significant since it illustrates the potential for growing covalently bound three-dimensional structures from fullerenes in a stepwise fashion via the self-assembly process. Two approaches may be taken towards fullerene self-assembly onto surfaces. Either a fullerene can be modified in solution with functionalities that allow for self-assembly, or a surface may be chemically modified with a reagent that undergoes a bond-forming reaction with a fullerene in solution. Herein, the authors report success via the latter approach. 13 refs., 1 fig., 1 tab.
