Introduction The fullerenes, including C 60 and C 70 , were discovered by Kroto et al. [1] in 1985 during experiments meant to simulate the chemistry of carbon stars. It was initially believed that these molecules would be formed primarily in carbon-rich, hydrogen-poor regions where formation of polyaromatic hydrocarbons (PAHs) would be limited. This hypothesis seemed to be supported by the fir...

A fullerene graph is a cubic bridgeless planar graph with twelve 5-faces such that all other faces are 6-faces. We show that any fullerene graph on n vertices can be bipartized by removing O( √ n) edges. This bound is asymptotically optimal.

In this work, two parametric L-Systems have been introduced to generate the figures of two series of nanostructures. These series consist of different spherical fullerenes with various number of carbon atoms. By specifying a parameter in each series a spherical fullerene can be determined. The members of the first series are C60 , C240 , C540 , C940 ,… which can be produced by applying paramete...

The 0 60 "buckyball" I a prominent member of the recently discovered family of fullerene molecules, is an unusual system with exciting properties. This contribution summarizes the present state of theoretical understanding of the equilibrium structure of carbon clusters, in particular the fullerenes, the optical properties of individual fullerene molecules, superconductivity in the alkali-inter...

[reaction: see text] The reaction of [60]fullerene with 4-substituted phenylhydrazine hydrochlorides in refluxing chlorobenzene under aerobic conditions afforded 1-(4-substituted phenyl)-1,2-dihydro[60]fullerenes, which could be subsequently oxidized to 1-acetoxyl-4-aryl-1,4-dihydro[60]fullerenes by manganese(III) acetate dihydrate in one pot. The transformation of ArC(60)-H to ArC(60)-OAc has ...

The thermo physical parameters thermal effusivity (e) and thermal diffusivity (α) have been measured using Fourier transform infrared (FTIR) Photoacoustic spectroscopy (PAS) for two different purities of C60 fullerenes (99.5 % , 98.5%) samples in the powder form. The experimental results shows that the values of thermal diffusivity is less then that obtained for crystalline C60 fullerenes. The ...
