... played by the solvents and organics in the structural evaluation of NiO nanostructures. The EDX measurement indicates that nanoparticles are composed of Ni and O, and the analysis in the NiO nano- particles/nanoflowers ... waste. Therefore, the technique could be extended and expanded to provide a general simple and convenient strategy for the synthesis of nanostructure...

... those metals. In the synthesis of SWCNTs by CCVD method, the temperature plays a key role. In this paper, we report the synthesis of SWCNTs by catalytic decomposition of methane over Mo 2 -Fe 10 /MgO ... catalyst and give a temper- ature window using Raman spectroscopy. With the relatively intensity of D band to the G band (I D /I G ) and the transmission electron micr...

... observed. Raman spectra for SWNTs show the presence of RBM, at 388.9 cm –1 , in addition to the G- and D- bands. The increase in the intensity of D-band for Ni- filled MWNTs is due to the non-uniform ... decomposition of methane over Ni–Cu–MgO catalyst [24]. Since the morphology of deposited carbon and the methane decomposition rate depend on the structure and natur...

Based on these estimates, we then propose an analytical statistical model of the interference ... moment of G, both exact (ana- lytical) and approximated (computed from the typical set). We can see that the proposed method performs very well for the...
