Regulating carbon hybridization states lies at the heart of engineering carbon materials with tailored properties but orchestrating the sequential transition across three states has remained elusive. Here, we visiualize stepwise evolution in carbon hybridizations fromsp tosp and tospstates via ...

The invention relates to a process for grafting compounds onto a material comprising on the surface a member chosen from carbon, silicon and germanium, said process comprising the following steps: a) providing a material which comprises carbon atoms at the surface, silicon and / or germanium in ...
The sp2/sp3 ratio governs the chemical and physical characteristics of the carbon electrodes. In general, literature results suggest that increasing the sp2 content will increase both rates of corrosion and HET kinetics [[5], [6], [7]]. The hybridization content (sp2/sp3 ratio) would also ...
The physical origin of the non-Arrhenius dc conductivity behaviour of charge carriers is explained through structural heterogeneity in graphene oxide introduced due to sp 2 and sp 3 hybridization of carbon atoms. The range of hop was calculated to be 4.7–3.8nm with hopping energy changing from ...
Carbon, sp3‐hybridizedLithographyPatterning, laser‐inducedA new method of laser-induced lithography for direct writing of carbon on a glass surface is described, in which deposition occurs from a transparent precursor solution. At the glass–solution interface where the laser spot is focused, a ...
Because isoelectronic B–C–N compounds can be thought as the alloys of carbon and BN, the possible structures of BCxN are usually derived from the structure of carbon (or BN), with low dense phases of sp2 hybridization or high dense phases of sp3 hybridization. The low dense layered B–...
The analysis of the band structure and density of states reveal that this new carbon phase has a metallic feature mainly due to the C atoms with sp2 hybridization. This novel 3D metallic carbon phase is anticipated to be useful for practical applications such as electronic and mechanical devices...
Raman spectroscopy has contributed to many fields of materials science, for example, in studies addressing Diamond-Like Carbon coatings. In the literature, discussions have arisen due to the various interpretations of Raman spectra and some studies have not recommended using it to measure sp 2 and ...
Electronic states of carbon atoms with up/down magnetic moments are plotted by brown/black line. Electronic states with the same spin direction can hybridize with each other. The hybridization involves the occupied and unoccupied spin-up states (e) and the occupied and unoccupied spin-up or spin...
