We sent our sample for virus imaging by TEM (Transmission Electron Microscopy), but after focusing on the sample, these strange circles appeared and spread rapidly. Do you have any idea what might be causing this?
I am looking for appropriate questions for interview in phenomenology?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
