Using a Scanning Electron Microscope

Показать описание

An instructional video aimed at third year undergraduates and above, in the basics of scanning electron microscopy. The film is a training aid, which the student is required to watch prior to hands on training. Thereafter, it serves as an aid to use of the equipment.

The video was written and produced by Katy McKenzie from the Department of Chemistry, Simon Lawes and David Weston from the Department of Engineering at the University of Leicester.

This film was produced by External Relations, University of Leicester.

Filmed & Edited by Carl Vivian

interesting, a field I gladly saw an even more potent price-revolution in.
Would love a tabletop SEM, here beside my computer on my desk but still quite steep for the average hobby-based joe, as they seem to raneg from 10k to 70k for these small modern desktop SEMs

Thanks, the Tutorial is Informative and Well Done.

When done, click "shutdown" on the windows 3.1 Taskbar prior to turning off the machine.

Hi University of Leicester,
I have question about SEM,
1/ Could SEM see nano materials, clearly or blur ? (I mean it's a normal SEM, not FE-SEM or high resolution SEM).
2/ If my material reach nano scale, could I use SEM to prove this material reach nano size?
3/ Which is the best method, cheap and convenience for characterizing (shape and size) nano materials?
I hope I would receive your answer soon.
Thanks University of Leicester so much.

Does SEM able to run multiple sample at one time?

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 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.

I much more prefer JEOL manipulation system using joystick and focus/mag knobs. Pressing a buttons doesn't look quite convenient.

This is a bit harder to use than a USB microscope.
