A complex characterization of single-walled nanotubes, synthesized by arc-discharge from different mixtures of layered materials (graphite and hexagonal BN), have been performed with Raman spectroscopy, UV-VIS-NIR optical absorption spectroscopy and high-resolution transmission electron...
The results of the detailed investigation of the chemical bonding and electronic structure features for the series of fluorinated multi-walled carbon nanotubes (F-MWCNTs) with different fluorine concentrations (5-55%) using X-ray absorption and photoelectron spectroscopy are outlined. All...
Hydrogenated and fluorinated single-walled carbon nanotubes (SWNT-H and SWNT-F) were investigated by micro-Raman spectroscopy. The as-prepared SWNT-H exhibits giant structureless hot luminescence that screens the Raman peaks. The luminescence background, attributed to random binding of the...
Interlayer tunneling spectroscopy on graphite stacked junctions and on aligned carbon nanotube (ACN) films shows universal zero bias anomaly (dip) for both type of objects. For graphite this anomaly disappears above 30K, while for aligned nanotube films it persists up to 350K. We consider this...
Abstract : The products of the transformation of different fullerites in the mixture with metal powders under a pressure of 5 GPa at a temperature of 1200°C have been studied. The initial fullerites were taken as soot extract and artificial mixtures of C 60 and 15-80% C 70 . A superhard phase...
Dendritic branches of oligo(phenylenevinylene) were attached to a C-undecylresorcinarene core. Two new supramolecular complexes were obtained between the dendrimers of first and second generation with the fullerene C 60 . The formation of the complexes 1:1 was confirmed by solid state 13 C NMR...
In this work we have estimated the resonance energy corresponding to E 11 optical transition in one-electron density of states of arc and HiPCO metallic single-walled carbon nanotubes on the base of experimental data obtained by two optical methods: the resonant Raman scattering excited by...
