Scanning Electron Microscopy (SEM) Basics

[@sharifuzzamanshakel9530]

Great explanation, Wonderful teaching, I've learned SEM basics from here a very good starting point for me. Thank you Dr. Tonya. Great teaching.

Vacuum might not be so good for the pen if you put it in there :p Get a really amazing image of ink splattered all over your beautiful instrument

[@jamato2004]

If no airbubbles in the ink nothing will happen....

[@Muradsahar]

Which book is it that you mentioned? For SEM read.

[@googlegoogle1610]

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.

Same intrest ...

[@hebanaser1864]

Same intrest ...i just had the images of mortar samples but its difficult to inerpret ..i am a student and not familiar with SEM

Thank you mam.... It's very helpful....

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?

Thanx a lot ma'am. Really really helpful and lucid. Can we get the copy of ppt as well ma'am? Since some images were nt much clear in labelling.

[@geoffrygifari3377]

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

[@nicolascg8053]

Fantastic explanation, but you go a bit fast to follow

[@tonyacoffey5568]

The nice thing about KZbin. Pause me whenever you like! Can't do that in a classroom.

[@basitkhan2934]

i think her pace is perfect to follow .....lol

[@ravirajverma1932]

Nicely explained Basic of SEM! Nice Teaching.

[@drabd3863]

nice lecture please i want the linc of slides of this seminar or video

[@narendrakumarjharesearchsc5159]

please tell how to do sem and tem on gfrp composite material detailed analysis.thanks in advance.

[@vortau9009]

Thank you very much! Exactly what I need :)

[@deepalipanwar681]

THANK YOU MA'AM FOR EXPLAINING THIS TOPIC IN A SIMPLE MANNER

[@duduraphael]

[@krishnajagtap1244]

nicely explained

[@YaremchukRoman]

Thank you

[@richardstone3638]

What is the book that is referred to?
