Figure 5: — Complex aggregate composed of a mixture of carbon nanotube and related carbon nanoparticles and silica (SiO₂) nanocrystal particles. (a) Bright-field TEM image with corresponding EDS spectrum showing C (Kα) and Si (Kα) peaks. The oxygen peak is suppressed in the X-ray emission competition. (b) Dark-field TEM image slightly shifted from (a) showing predominantly SiO₂ strongly diffracting nanocrystals (reference X). The principal diffraction regimes marked 1 and 2 in the SAED pattern insert are characterized by overlapping (002)_C/(101)SiO₂ and (100)_C/(200)SiO₂ diffraction, respectively [26].
