The results of recent investigation of fullerenefullerene hydride system as a potential high capacity hydrogen storage option are presented. Theoretically, C60 fullerenes can reversibly store up to 7.7 wt.% hydrogen by forming fullerene hydride C60Hx. However, high temperature and pressure are currently required to enable hydrogen exchange in this system. For example, direct hydrogenation of f...
A [70]fullerene-benzodifuranone acceptor dyad synthesized by a Ag⁺-mediated coupling reaction was used to construct a thin-film organic solar cell. The fullerene and the benzodifuranone dye in the dyad have close-lying LUMO levels in the range of 3.7-3.9 eV, so that energy transfer from the dye to the fullerene can take place. A p-n heterojunction photovoltaic device consisting of a tetrabenzop...
Received 15 April 2003; in final form 25 April 2003 Abstract Single-walled carbon nanotubes with narrow diameter-distributions were synthesized by the catalytic CVD technique using fullerene, C60 or C70, as the carbon source. Fe/Co bimetal particles supported with zeolite powder were exposed to fullerene vapor in a heated quartz tube furnace. With a precise control of fullerene vapor pressure, ...
The newly found B40 is the first experimentally observed all-boron fullerene and has potential applications in hydrogen storage. Here we investigate the binding ability and hydrogen storage capacity of Ti-decorated B40 fullerene based on DFT calculations. Our results indicate that Ti shows excellent binding capability to B40 compared with other transition metals. The B40 fullerene coated by 6 T...
We present an overview of solid-state NMR studies of endohedral H(2)-fullerene complexes, including (1)H and (13)C NMR spectra, (1)H and (13)C spin relaxation studies, and the results of (1)H dipole-dipole recoupling experiments. The available data involves three different endohedral H(2)-fullerene complexes, studied over a wide range of temperatures and applied magnetic fields. The symmetry of...
By using the molecular dynamics method, a clustering process of randomly distributed carbon atoms was simulated. A C60 imperfect fullerene obtained in the simulation was kept at 2500 K in order to evaluate the effect of the collision-free annealing process which was almost ignored in the clustering simulation. Through successive pentagon-migration transformations, the perfect fullerene structur...
BACKGROUND The cause-effect relationships between physicochemical properties of amphiphilic [60]fullerene derivatives and their toxicity against bacterial cells have not yet been clarified. In this study, we report how the differences in the chemical structure of organic addends in 10 originally synthesized penta-substituted [60]fullerene derivatives modulate their zeta potential and aggregate'...
A cross-linker and an elastomer are used to increase the mechanical compliance of active layer in organic solar cells based on fullerene non-fullerene acceptors without compromising their performance.
