- X-ray diffraction (XRD) is a tool for characterizing arrangement of atoms in crystals and distances between crystal faces. This can be used to identify atoms and the crystalline form.

Excellent presentation. Now, it is crystal clear.
I am no teacher but have done a little with XRD. If you have the XRD data you have to figure out what the crystal structure of the material is. FCC, BCC etc. Next you use Bragg's law knowing the hkl values for each peak and you can calculate the lattice parameter (d=a/(Sqrt(h^2+k^2+l^2))
There are some minor mistakes in this video, but she does a great job to introduce the subject. Thank you.
Just stumbled upon this when searching for "x-ray" and was surprised to see a Bruker D8. I use one myself for my bachelors project.
This was fun to see, cheers from Uppsala.
Great detail, I have a 3 hour demonstration this week, not sure if the same machine but hopefully this gives a good enough overview to know what questions to ask, thanks!
Thank you for the amazing demo!
Good mannerisms when explaining I wish she was my prof...
Presentation is helpful, clear and provided basic information to learners
very clear English without any strange accents so it was very understandable
very clear and valuable!
Thank you very much for the video. The explanation is excellent :)
Thank you very much for the information
why wasn't a binder used with the the powder?
Nice and self explanatory video...
Good Explanation
Thanks a lot! Very clear and interesting explanation
thans ...this video very important to explain XRD
really great! Thank You
I love you. You provide great video.
Useful video but I am using bruker D8 advance and I love it.
Very good video, thank you !
Vey well explained... thanks a lot
nice presentation thanks a lot
Great video
A perfect demo
This is great, thank you.
Thanks for the information. may God reward you, amen
To handle this equipment we need to ware something x-ray protection coat..I mean there is any affect on body while using this instrument??
At 4:50 As long as the doors are closed there should be no need for extra safety protection.
nice & full flow vedio.....
dear teachers how to i find out the lattice parameter? thanks you
It is easy to build your own x ray machine. Take a dental x ray tube. Hook up a 30,000 tesla coil (build one from a kit) to the tube's cathode. That is it. Very simple. Buy sheet photography paper and, under a red photo lamp, hold a chicken leg between the film and the anode of the tube. Develop the film. You will see the bones but not the flesh.
its funny that no one looks anything up on youtube that might actually teach you something, i just learned something, this video has only 9000 watches
To TheFlexability: This video has 128,003 views now. FWIW I have a RUclips account specifically to get an education and learn. While I do watch entertainment, news, and commentary, the primary purpose is education and learning in science, engineering, and technology.
very helpful tube :)
TY!
Thank you
thank you so much....
very usefull v.......
Anybody has knowledge about the price of this machine? or an estimate of the price? I'll appreciate your help cause I'm working on a project and I need that information,
Don't know if it is still relevant but just the tube itself is about 9000 USD on average. Not speaking of the generator, goniometer etc. so the sum of the machine could be about 13-15000 USD.

awesome, thanks :)
Tq for explain
Good
cool
Crystalograpy is imagination or it really exixt,
Means all this theory in material science of lattice, crystal, ect, is imagination or......
It exists in reality
Thank you.
thx
Tanks
You ask a lot of questions.

Where are your gloves and goggles ?
+Kathryn Laraia you're taking this way to seriously
may be you are taking x rays too lightly :P
Good lab practice is to always wear protection.
What for? The material obviously isn't hazardous and the lead glass provides protection from x-rays. Neither gloves nor goggles help with that. Unless she uses materials that require it it's absolutely needless to use so much protection. On a personal note using them is also extremely uncomfortable in most cases.
