Explained really well in a simple way. Wish I had you as my teacher during my engineering. Really appreciate your efforts. A student from Lahore, Pakistan.
I really appreciate your video, can you make one for the tertany phase diagram ?? maybe it's not something that we can ask for. If this is the case i'm sorry for my rudeness, you have already being very helpfull for my master Nanobiotechnology, surface and catalysis in the ucl university( from belgium) Best regards, O.M

in simple cubic packing at each edge you have 1/8'th of an atom with 8 edges it completes up to 1 atom per one cubic cell but in other packing factors (bcc or fcc) at each edge we have less than 1/8'th of an atom but yet we take it as 1/8'th why is that so?
In simple cubic the atoms are at the corners of the cube. So each corner in the unit cell has 1/8 of an atom and there are 8 corners which equals 1 atom. This is true for fcc and bcc too. It's just that in bcc and fcc structures you have atoms at places other than the corners. (bcc in middle of cube, for example). This gives you more atoms in your cell than simple cubic. I'm not really sure if that clears up the misunderstanding. So in fcc and bcc we are STILL taking the corner atoms as 1/8, not less than 1/8.
@@tonyacoffey5568 So in simple cubic packing structure there is no atom neither at the center of the cubic cell (BCC) nor at the faces of it (FCC) so nothing pushes the atoms from the edges, for example in BCC, the atom at the center must push the atoms at the edges outwards so it can fit inside, doesn't it?
@@metinibrahimdemir1877 No. The atom at the center does not push the other atoms out of the way. What kind of structure is formed depends on the conditions (temperature, pressure, etc) and the type of atom. This affects how densely the atoms can pack in. BCC packing is more dense than SC packing. FCC is more densely packed still. So nothing gets pushed out of the way. The atoms "want" to pack more tightly for BCC and FCC structures than SC. Instead of pushing out of the way, picture instead atoms hugging each other in.
if you don't like lectures there's a lot of free and easy to find material on material physics online. even slides from lectures (probably also this one) even though i don't understand why you want them instead of an actual book.
This amazing lady single handedly carried me through my materials engineering module. Her delivery is impeccable. Thank you for all your vids
This is a lot similar to what we learned during an introductory geology course on minerals. Its nice to draw parallels, and it only makes sense.
This is so good. I can't even say how grateful I am for this work.

lahore lahore aeeeee
Thank you very much for this video. The theory is now more clear to me. Keep up the good work 💪 👍 !!!
thank you so much tonya!!! your videoes made our whole class pass the material science exame :D Love from Denmark
nice and conceptual lecture i like it so much.
Glad I found you. Do you have videos for the chapters before this topic?
Thank you for your effort, I am very grateful 😊
Thanks for everything.
Can you tell us what is the source of books. Or the book you get the lecture from it
I use Callister and Rethwich's textbook
Mam I'm from chemistry background for me your lecture was amazing ..... Can I gotten your lectures PPT slides..?

hello, what is the title of the book you are using Dr
my structures prof stole your lectures and he can't even teach. So glad I found the original source

@@SHAKER239 Where can we get such valuable slides??
Any idea?? I have an upcoming exams...this could save the day!!
LOL!!!
Where could I download this powerpoint?
Please share a link to download this presentation
❤😊Thank you ❤😊
Sorry,i hv a question,why theoretical measurement for density is always lower than actual measurement
you are wonderfulll womann
what do you meaN by fractal structure

If it is less than 1/8 as you said, will the other cages in a crystal structure consisting of bcc cages have more than 1/8 atoms in each corner?
title of the book @tonyacoffey5568
Which book are you using ma'am ?
She is using Materials Science and Engineering An Introduction, by William D. Callister, Jr. and David G. Rethwisch, maybe 9th edition
Mss can you send the slides for the lesson
thanks a lot madam
CC(C)P Structure heheheh
why covalent compounds are more likely to be noncrystalline
because of the directionality of the bonds. The bonds are not spherically symmetric
Mam please give your pdf notes
Teaching is so lame these days. Throw those slides up and we are golden!
