然后,NCDs繁茂的官能团在热解过程中被脱水和碳化,构成N掺杂sp2/sp3碳界面。随着这一过程的继续,成功地构建了Ru纳米粒子负载于以N-掺杂sp2/sp3碳界面为特征的碳基底上的混合结构(图1b)。 图1.(a)Ru/NCDs的合成示意图。(b)Ru/NCDs...

Here we report the use of transmission electron energy-loss spectroscopy (EELS) to obtain a map of sp 2 and sp 3 carbon at a spatial resolution of less than a nanometre across the silicon–diamond interface. We find that diamond nucleates on an amorphous carbon layer, with the transition ...
Tunable hybrid sp3 and sp2 carbon composition and pore structures stem from the structure transformation of ionic liquids to polymerized organics and introduction of Co metal salt. Through tuning both composition and pores, the 3D Nヾoped nanocarbon with a high ratio of sp3/sp2 on the surface ...
sp3–sp2 vs sp3–sp3 C–C Site Selectivity in Rh-Catalyzed Ring Opening of Benzocyclobutenol: A DFT Study The Csp3–Csp2 vs Csp3–Csp3 site selectivity in the C–C bond activation in Rh-catalyzed ring opening of benzocyclobutenol was systematically invest... Lina,Ding,Naoki,... - ...
Carbon, sp2‐hybridizedCarbon, 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 ...

The sp3 hybridization content extracted from XPS is consistent with the atomic density derived from the plasmon energy in the EELS spectrum. In our theoretical study, we generate several periodic model structures of amorphous carbon of different densities applying two schemes of increasing accuracy in ...
The metal-catalyzed or -mediated cross-coupling between a carbon nucleophile and carbon electrophile is one of the most important methods for the construction of C鈥揅 bonds. A variety of metals can catalyze this reaction. This chapter covers the most relevant coupling reactions between sp 3 and...
