Rietveld refinement in 4 minute │The simplest way to refine XRD results │ using MAUD

[@tinydragon2013]

Thank you for a short and clear video. You haven't changed the instrument parameters in this video, I thought you need to use and calibrate the correct instrument type in maud

[@ahmarmehmood9438]

I hope this video will help the people who wanna perform Rietveld refinement. Just a quick suggestion, Its better to speak while writing so that this can be more helpful to the audience

[@subhendrakesharisahoo8489]

hi...I wanted to calculate the weight percentage of different compounds in a composite .To be specific quantity of formation of mullite as it may contain alumina or silica also....how can I do that using rietveld refinement...can you please let me know the procedure?

[@tejaswihegade]

If I don't have CIF file for my compound, then how do I get X, Y, Z, B and Occ values? Please help me in finding them.

[@kate_okay]

If you found out how, tell me. Please)

[@lovephysics]

Awesome. Very useful. I request you to explain, rather than music. What type of file is required to be opened in MAUD ? Is it free software?

[@InSciLab]

YES it is free! maud.radiographema.eu File: .dat or .xrdml Thank you very much for your comment.

[@oddeology1259]

So how do you reduce the sig value further...also, I have a good sig already, but my Rwp is still bigger than 10, how can I reduce it?

[@JamalUddinPrativasic]

Nice work! I really loved it! When can we get the next video? I really want to know how we can reduce the sigma value even more.

[@sarveshkumargupta6988]

Sir, your videos are very helpful and knowledge full. If I do not get cif files of some molecules then how can I do refinement of this. I have composit materials XRD , then how can I refine it using full prof. Please help me.

[@mahasenhussein1401]

I have the same problem now. If you can overcome it, can you help me?

[@ege9595]

Thank you for this helpful video. I have a problem regarding the theta angles, do you know how to solve it? Basically the theta values of my peaks and theta values found in phase cif. files are not exactly the same, so I can't apply the Rietveld refinement properly.

[@InSciLab]

Find a better CIF. Maybe same structure but different composition is okay

[@harshwardhanwadikar793]

You are a savior, right now for me! Would these calculations be accurate enough to report in international journals?

[@InSciLab]

For structure confirmation (to report the crystal structure and space group, indexing peaks) this will be okay, I guess. But, if in your paper, structure is one of the important topics, then I suggest you to do FullProf refinement. Because, 1) MAUD is not recognized well 2) the method I showed takes care only very preliminary things. There are 3 videos on FullProf in my channel itself. I am sure those will not be very hard. If you want to do MAUD as an expert you can contact inventor Luca Lutterotti. He is very humble to help. let me know if you want his contact.

[@harshwardhanwadikar793]

Hello. I would like to know how I can use Maud to calculate an amorphous percentage

[@InSciLab]

For that you don't need Maud. You can do it using Origin itself. Let me know if you want a tutorial video showing how to do that using origin.

[@AnkitaSingh-un3sj]

Which should be preferred Maud or fullprof?

[@InSciLab]

Fullprof. If you don't have much time to learn or refinement result is just a supporting data, have not much importance then you may use Maud. This is my personal opinion. Otherwise both are okay depending on usage and knowledge you have.

Is there any reason you're not supposed to maximize the window? I installed MAUD and opened it, but the window is much smaller and doesn't show the graph like your video shows.

[@khurshedalam1908]

I appreciate your work thanks...Do you think it is possible for high entropy alloys thin film, containing at least 5 elements (CoCrMoMnNi) ....As i input all these elements in Craystallography dtata base but nothing shown....

How does it work with organic compounds ?

It depends on the structure and experimental data. you can try with organic and let me know how does it work. I have no experience with xrd of organic sample.

how can I obtain the crystallite size?

Go to the result file. The calculated values for crystallite size for each peak are listed with the peak list. read carefully as the columns are spaced very closely.

hm..i did it as you showed us in the video. but i only could find the d-spacing values for each peak. (e.g for (001) --> 4.0863295).

Refinment of respective options from refine wizard is necessary to get crystallite size. Try if you don't find let me know.

You can find out most similar structure. for example if you don't get CIF for PbTiO3 then you can search for CaTiO3 or BaTiO3 as these are having similar structure.
