Fullerene graphs are trivalent plane graphs with only hexagonal and pentagonal faces. They are often used to model large carbon molecules: each vertex represents a carbon atom and the edges represent chemical bonds. A totally symmetric Kekulé structure in a fullerene graph is a set of independent edges which is fixed by all symmetries of the fullerene and molecules with totally symmetric Kekulé...

Effect of electro migration on crystal structures of platinum nanowire (Nano bridge) during Nano-gap formation is investigated by means of Transmission Electron Microscopy (TEM). Selected area diffraction patterns as well as bright field images are used for this investigation. There were severely recessions in the polycrystalline Nano bridge and crystal structures around the nanogap changed ...

Using molecular dynamics calculations, we investigate the absorption of a C(60) molecule in a (10,10) nanotube either through the open end or a large defect in the tube wall as possible scenarios for the hierarchical self-assembly of (C(60))(n)@(10,10) "nano-peapods." We find the absorption through a defect to be significantly more efficient than the end-on absorption. This process occurs most ...

An experimental and theoretical investigation on the chemical reactivity of fullerene cations (Cn+, n = [36, 60]) with amino acid molecules (e.g., isoleucine, C6H13NO2) is performed. The results show that, in gas phase, can react to form fullerene/amino cluster high efficiency. formation rate constants for ion–molecule collision reactions between isoleucine are estimated under pseudo-first-orde...

A structural model for intermediate sized silicon clusters is proposed that is able to generate unique structures without any dangling bonds. This structural model consists of bulk-like core of five atoms surrounded by fullerene-like surface. Reconstruction of the ideal fullerene geometry results in the formation of crown atoms surrounded by π-bonded dimer pairs. This model yields unique struct...

cu2o nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used as solvent and reductant. span 80 was applied to control the morphology of cuprous oxide nanoparticles. the nano structure of the complex was characterized by x-ray diffraction measurement...
