[3dem] unknown structures

[Sharon G Wolf]

Related to Chris’ comment; I wanted to ask you Roman, do these burn under the beam? How beam resistant are they? Compared to water, ice crystals, carbon foil or ethane contamination? That will give you a clue.

This looks quite a bit like ‘clusters of metal nanoparticles’ — something I’ve looked at quite a bit in the EM.  I take it from your question that you’re not expecting to see metal clusters / metal nanoparticles in your sample?

Cheers,
Chris

Dear all,

I would like to have you expert opinion on what the structures in the attached image might be. The structures are quite dense in my opinion. I have my ideas but I am not at all sure. I hope any of you have seen similar structures.

Best regards,

Roman
