These imperfect fullerenes were kep...

The fullerene C70 may be considered as the shortest possible nanotube capped by a hemisphere of C60 at each end. Vibrational spectroscopy is a key tool in characterising fullerenes, and C70 has been studied several times and spectral assignments proposed. Unfortunately, many of the modes are either forbidden or have very low infrared or Raman intensity, even if allowed. Inelastic neutron scatte...

Recent theoretical results for the response of Czo , CGO and C70 fnllerene clusters to external electromagnetic fields are reviewed. The calculated static response of free eGO has large linear and nonlinear components, the latter being much smaller than originally suggested and significantly reduced by screening effects. Random field approximation calculations indicate that the dynamical dipole...

In this work, a rapid and sensitive method, based on ultrasound-assisted extraction of samples with a small volume of toluene, has been developed for the quantification of C60 and C70 fullerenes in soil and sediments. Good extraction efficiencies were obtained at all of the fortification levels studied (200, 100, 20 and 2 ng/g), which ranged from 72 to 104%. An important effect of the extractio...

A synthetic methodology is reported that functionalizes C60 and C70 fullerenes with dihydroazepine rings by a cascade reaction encompassing rhodium-catalyzed cycloisomerization of 1,5-bisallenes [4+2] cycloaddition. This transition metal-catalyzed provides versatile step-economical approach to the synthesis 6,7-membered polyheterocyclic fullerene adducts. Electrochemical characterization produc...

The impact of a challenge with moderately pathogenic <em>Escherichia coli</em> O128:C6 on the digestive physiology and gut bacterial community growing rabbits under two feeding programmes was analysed. Upon weaning (28 d old), 180 were allocated to four groups (9 cages 5 per group) for weeks: group C100 non-inoculated fed <em>ad libitum</em>; C70 feed intake limited 70% ...

To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...
