Standard C black similar to fumed silica. A aggregation of fused sub- and post-micron particles caused by solid-solid diffusion of small primary sized particles. This micrograph illustrates the reason for the use of C black as a rheology modifier in car tires. Take a look Slide 9 in:

Note that the other C Black (Cilia) died recently.
It looks as a conventional aggregate of carbon black nanoparticles. It is difficult to say more for such quality of picture.
It is necessary to use HRTEM and EDX for detail characterisation of such specimens.
Good luck!
The TEM image shows that there is aggregation of nanospheres . These nanospheres are uniformaly deposited on a thin film. But it is difficult to say about the single crystalline, nanocrystalline or polycrystalline nature of sample. Better to perform the HR-TEM analysis of your sample. moreover if you want to know the elements in your sample go for XPS analysis. it will give you oxidation state of each element as well as confims presence of elements in the sample.
