What led me to this channel was a question I had, the s.e.m. was invented in 1965, my question was, who invented it, what company funded the work and, what years where the advances in this tech made and what company or other, funded those advancements?

How cool is it that somehow the magnetic lenses can focus those electrons in a beam to a small spot, even though they repel each other even inside the beam! I imagine the electrons must move fast enough (high enough momentum, and kinetic energy along with it) to counteract Coulomb repulsion

What kinda differences would be there if I go for SEM testing of (1) cement paste i.e., cement plus water (2) mortar i.e., cement + water + sand, and (3) concrete i.e., cement + water + sand + gravels? Also let me know which case would be more appropriate in order to discuss the phase characterization of the products formed therein such as the main hydration products e., CSH (calcium silicate hydrate) and CH (calcium hydroxide). One more thing.....how can I assess the structures of either of these two hydration products in which case, I have to first dehydrate my samples prior to going for SEM testing (during the sample preparation stage)? So if dehydrated, there would be neither CSH nor CH in the prepared samples for SEM.
