Microscopes: optical vs SEM vs TEM vs AFM

[@ABCchill]

Fantastic Video. Small correction: You cannot see alternating Doublebonds in graphene, as there is no difference between the single and Doublebonds. But you probably know that already :)

Why do atoms look round in TEM images even though they have different orbital shapes?

VERY HELPFUL... Thank you taylor, i want to ask you when you where explaining SEM/EDS, you said that the inclusion is a secondary phase, i want to know how do you know that it's a secondary phase?

[@TaylorSparks]

well, we see a totally different chemical composition (inclusion hs S-Fe) but the rest of the structure is (Fe-O-Mg-Mn etc)

@@TaylorSparks thanks for replying taylor but i still didn't get it, i mean yes i get that it's a different phase but i didn't get it how it's a secondary phase or primary ...

[@TaylorSparks]

@@omarfaysal6443 oh come on you would need to see the whole microstructure. The larger phase is the primary and the smaller phase is the secondary
