As a exclusion, carbon bind themself not in form of identical molecular orbitals but in form of hybridization. I explain the term hybridization and specify the in uence to the properties on the example of graphite and diamond. Furthermore, I present the change of properties by curvature e ...
D Wan - University of California, Berkeley. 被引量: 0发表: 2004年 Diamondlike amorphous carbon films prepared by magnetron sputtering of graphite Amorphouscarbonfilms,a‐C, were prepared by employing dc magnetron sputtering of a graphite target in an argon plasma. A series of a‐C films were...
X-ray photoelectron spectroscopy was used to quantify the sp 2 and sp 3 contents, which are discussed below in relation to the I D /I G ratio and the prediction of the amorphization trajectory of graphite. In an attempt to find a relationship between these characterization techniques, a ...
The sp 3 crystallites range in size from 9 to 30 Å and are scattered randomly throughout the sample. A UV Raman spectrum shows a broad band at the location of the expected diamond peak, together with a peak corresponding to the graphite region. We conclude that the patterned carbon is...

Diamond coatingsWettabilityMachinabilityBULAluminumIn the present paper, a graphite–PTFE composite coating (Gr-x) on an HSS end mill is proposed for machining aluminium. The suitability of this coating was first simulated in a pin-on-disc test and was compared to the performance of MoS2 before ...
The results support the so-called H-model for the (111) surfaces of diamond-like crystals, and exclude the possibility of graphite-like delocalization.doi:10.1016/0166-1280(83)80169-9Vincenzo BaroneCattedra di Chimica Teorica, Università di Napoli, Via Mezzocannone 4, I-80134 Napoli, Italy...
The interatomic distance in such four-member rings is anticipated to be an intermediate between diamond and graphite. This particular atomic configuration is considered as an intermediate hybridization in between single and double bonds. We posit that the oriented growth of the diamond on (0 0 1)...
