Fullerene blacks with 0.7–4.5 at% of nitrogen incorporated into their carbon framework were produced by feeding N 2 gas into the center of a carbon arc through a hollow graphite electrode. The formation of toluene-soluble fullerenes is effectively suppressed under these conditions. Optical emission spectroscopy of the arc plasma revealed the presence of N atoms and CN radicals. Chemical composition...
The dependence of the optical absorption density on the UV irradiation time of a biological sample (the suspension of thymocytes, isolated from Wistar rat thymus) and the DNA structural state in cells under X-ray irradiation in the presence of the C 60 fullerene aqueous solution were investigated and analyzed in detail. The significant pro-oxidant effect of this material at the low concentration...
Monte Carlo computer simulation results on the adsorption of ethylene on C 60 fullerene are employed to locate the adsorption sites observed for the adsorption of other simple gases. The distributions of molecules according to the gas-solid interaction energy obtained from the simulations are in agreement with experimental results reported in the literature. We focused our attention on...
