SEM Particle Size Determination using ImageJ

This video is a demo on the particle size determination from SEM images.

Hi Jeyadheepan K,
I have question in your video,
I see your materials reach nano size.
1/ This is a SEM images, why your image has a good resolution ?
Because I saw FE-SEM and TEM has a better resolution but this images (FE-SEM & TEM) so blurry with nano materials (I read paper about fibers)
But your SEM so very good resolution.
2/ If your materials reach nano structure, which is the best method to prove your materials reach nano structure (should use SEM, TEM, FE-SEM or AFM)
I hope I would receive your answer soon.
Thanks Jeyadheeepan K so much
Best regards.

informative video.. thank you sir..

Sir, how can we measure diameter, if the particles are non-spherical or mixed shapes? Then, is the A=πr2 remain valid?

[@JeyadheepanK]

Here, mostly the random shaped particles are approximated to the spherical nature, since they are in nanometric range

@@JeyadheepanK yes sir, i have got that but i asked for non-spherical shaped/irregular shaped particles. How could we measure their size from SEM images?

Thank u sir

Did you ever automate this process with python?

Trying to do this now
