Several recent experiments have provided compelling evidence for stable hybrid carbon nanotubediamond structures. In experiments by Kuznetsov et al. [1,2] the formation of nanometric closed curved graphitic structures with tubular or conical forms attached to a surface of a diamond particle were observed in high-resolution transmission electron microscopy (TEM) images of diamond particles after...

Raman spectroscopy is a very popular, non-destructive tool for the structural characterisation of carbons. Raman scattering from carbons is always a resonant process, in which those configurations whose band gaps match the excitation energy are preferentially excited. Any mixture of sp , sp and sp carbon atoms always has a gap between 0 and 5.5 eV, and this energy 3 2 1 range matches that of IR...

The investigation on elemental carbon has long been of nanotubes to diamond at 4.5 GPa and 13008C using a considerable interest because of its great importance in six-anvil high pressure apparatus with the existence of both science and technology. One of the most outstanding NiMnCo catalyst. The detailed characterization conducted achievements which occurred in carbon science was the shows that...

Molecular dynamics simulation was used to study graphitization process of a small diamond cluster at 1200, 1500, and 1800 K. The cluster was in the shape of a sphere of about 3 nm in diameter, and interaction between carbon atoms was described by the reactive bond order potential. Results obtained for 1500 K showed transformation of diamond nanoparticle into a carbon onion with diamond-like cor...

a r t i c l e i n f o The adhesion of Pt to carbon surfaces is an important technological consideration in proton exchange membrane fuel cells (PEMFCs). Thin films of Au, Ti and Cr were deposited on graphite, non-hydrogenated diamond-like carbon (NH-DLC) and hydrogenated DLC (H-DLC) coatings' surfaces using a physical vapour deposition (PVD) process. The friction force curves obtained from slid...
