Dear Janusz & Gert,
I ve added the images of Ceriabased nano-composites.Can you explain about the image??
Depends on image, I think. Add some images, let us know what you mean. Probably it helps us to answer more clear ;)
Janusz is right! What kind of question is this? Can you answer the question why today I did not like the food in the canteen?

What I can see i surface of polymer/ceramic/metal, which was prepared via cracking way - I suppose. As I remember, few years ago I had some project according to nanoparticles and they was 10 - 50 nm eq. diameter. It is really difficult to see nanoparticles on scan 4x4 um. Try to make smaller scan 0.5x0.5 um. It will be much more easier because Z range will be lower to. I attached image I made aprox. 15 years ago: nanoparticles on mica. Taking into consideration the way of preparation, note this is the key for AFM imaging. Without good prepared sample, AFM will not work as one expect. Depends on matrix (I do not know what it was) I think Tapping Mode and Phase Imaging may give you best results. Choose tip with frequency 100 - 200 KHz (my preferred are APP NANO ACTSA), what is enough for play with PhaseImaging frequencies, but with standard resonant frequency it may be ok, too.
Many many thanks Dr.Janusz for your insightful suggestions.I will go through the image vividly.I got the basics of AFM imaging.
Regards,
Osim
