One of the best video I came across. I feel he is explaining the things with his own SEM operation experience

[@myx0myc0t4]

hey! i have to give lectures on SEM for primary school kids, and some of your explanations (like close your eye, and scan the surface of the stone) made it possible to make them understand it easier. Thank you.

[@jannatkhan7108]

In which country, because we are studying about Sem in undergraduation?

[@myx0myc0t4]

@@jannatkhan7108 i'm based in the UK. I work at a secondary school, where we've participated in a program to host a tabletop SEM for several weeks, to introduce students to this field of STEM learning, doing project works, etc, because it's amazing, it can be a whole new and full carreer path and most students don't even get to hear about it, or see it, unless they've already chosen STEM subjects for their undergrad. While we had it, we've done outreach work, for primary schools, a little fun interactive "can you guess what you see" session.

It is very helpful. And helps us to understand more.... Make more videos about physics related topics.. Plz sir.. It will be very helpful..... And thank you so much.....

[@shomusbiologyofficial]

Sure. I will make a video series on that topic soon

[@nooryaseen9388]

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.

[@abouthaiinasadallah2261]

thank you so much

[@shomusbiologyofficial]

You're welcome

[@melonenkopf2790]

Please help me. Under which conditions do the incident electrons cause secondary/backscattered electrons and under which conditions do they cause X-ray? So of course if they are absorbed they release X-rays. but why are they absorbed? same thing with secondary electrons and backscattered electrons. Please pardon my bad English. If you could answer this you'd be my hero of the month

[@MuhammadShahid-sn9hk]

Sir g . Kindly AP is topic pa vedio banyia ga. Electrone microscope and HAADF. High-angle annular dark-field imaging (HAADF) is an STEM

Sir plz freeze fracture electron microscopy bi kra dijeye🙏🙏

[@bilalbawab5568]

thanks that was very helpful but i want to ask about heating the surface of the material due to electron collision, may it affect the internal or surface microstructure and grain size if i use the sample for repetitive analysis? or it is ineffective?

Backscattered electon secondary electron or x ray production..how they depend on surface properties of the specimen?

What is the meaning of specimen

[@varadharajan3218]

Can you please explain the Focused ion beam technique.

[@pathakpathak9018]

is SEM creates an image like TEM?? or just gives an idea about surface structure???

[@sciencestudycirclebydeepak8265]

Sir can give note of lecture

[@swatipujar9504]

Is there any specific reason for using magnetic materials as lens here? Also when the electrons come out of the sample, how do the detectors know whether it's a back streamed electron or a secondary electron?

[@bhutianopu96]

Why why why? why always the educational videos has noise or some kind of problem in video quality?

[@misamisa9031]

Backscattered electrons are actually the electron that is reflected from adjacent to nucleues not it is same like secondary electrons

Sir please scanning transmission electron microscope(STEM) ki bi video upload karo

Anode consist of negative charge not positive charge

[@argeurasia]

I think it's too long winded. It could have been a much shorter video.

[@Nikopolidis62032]

WTF, whtas the resolution and magnification?

[@manuelsputnik]

he mentions it in the TEM lecture that comes after this one. He compares magnification and resolution of optical vs SEM vs TEM

[@palldhawan]

Anode is negatively charged. Not positive. People who have not studied physics or chemistry will get the wrong concept. Kindly correct it.

[@shomusbiologyofficial]

No
