there is no structural information for any of my phase, could you please tell me how to get the structural information???
@IAMMDiffractionFacility 7 күн бұрын
I think the Crystallography Open Database (COD) can provide files with structural information. I would suggest trying to use that. If you can save a .cif file with structural information, you can load that into HighScore Plus and refine it (I think you just have to do choose File, Insert, and then choose the .cif file).

Great video! I'm a bit new to XRD analysis, and I have a question. I have a GdInO3 sample which does not have a literature space group. I want to use the XRD patterns I've collected to determine the space group of the sample. Any tips?

Hello dears, I am using XPERT high-score software to analyze the cement mix's XRD results. Although the major phases have emerged, I am having some issues. 1. Why do the main phases chosen from the pattern list not show up in the section on refinement control? 2. During double-clicking, one of the primary phases to view the details, there is no section on the structure and anisotropic displacement parameters. 3. Aside from these treatment options, how can I refine my graph to make it more readable? I would appreciate it in advance.
@IAMMDiffractionFacility Ай бұрын
There are a couple of reasons I can think of quickly. 1) Do you have HighScore or HighScore Plus? I believe only the Plus variant has the capability to perform Rietveld refinements (but I'm not 100% sure of that). 2) If you are using HighScore Plus, it may be that your database of diffraction patterns doesn't include atomic positions. If this is the case, I THINK that the Crystallography Open Database (COD) has atomic positions in their files (or at least some of them), and it is a free database, so that might be something for you to look into. I've not used it personally as I use the PDF-5+ database from ICDD, but I've seen the COD recommended. Regarding making your graph more readable, that is a bit too broad of a question for me. Can you be more specific? Is there something in particular you want the graph to show?

Thank you very much for your high quality content and dedication. Really hope your channel will be seen by many more people. I got solo-access to a xrd about a year ago and since then I'm more or less teaching myself with literature and webinars (to be honest, the whole reciprocal space, symmetry and rietveld - thematics are very challenging, but "simple" measurements and phase qualification is getting better). My high-score software version is quite old (2.2) and the refinement controls aren't like in your tutorials, I guess the database is a bit outdated, too. Your content is incredibly helpful and your slightly longer introduction-video got me hooked. I'm very interested and looking forward to your next video - series, already ordered the book you recommended. Wish you and Benjamin all the best.

@WWC94 Wow, that message means a lot! I really never thought when I started this channel that it would have much reach outside of the users of my own lab, but knowing that it helps others has really encouraged me to keep it up and expand, even when the thought of expanding is a bit...intimidating. My intention was to produce only training videos on how to use our instruments. However, making videos focused more on the science behind X-ray diffraction has actually helped me as well. You don't REALLY know a topic until you try to teach it. As you said, stuff like reciprocal space, the details behind Rietveld...these types of topics can be difficult to grasp and then understand well. I'm not going to pretend that I'm a genius when it comes to X-ray theory; I'm better on the experimental side of things. I'm also not the kind of guy to understand a concept through equations, I need words and clear images to paint a picture to allow me to visualize what is going on. I figure that I'm not the only person like this though; there's probably a lot of people who are similar. My goal is to make content to help those people. Unfortunately, it is very time consuming to figure out how to simply a complex topic, which means this series will likely take much longer to complete than I anticipated. I hope that my viewers and subscribers will be patient with me! Anyway, this comment is longer than I intended. I just want to thank you again for your kind words. You didn't have to take the time to comment what you did, but it was very kind of you to do so. I hope you enjoy the rest of the channel's content, and let me know if you have any specific questions in the comment sections!

Thank you for the wonderful effort you made on the expert score tutorial. I am using COD database compatible with Xpert highscore plus for Rietveld analysis. I continued with the tutorial until the step you change the phase asignments to pattern by CTRL+A and right clicking. After doing so, I did not find any numbers or phase names appearing on my graph.
@IAMMDiffractionFacility Ай бұрын
@ahmadabubakar1364 To be honest, I am not overly familiar with the COD database as I have always used the ICDD database. I have two thoughts though. (1) Do you have HighScore or HighScore Plus? I believe you can only perform Rietveld refinements with HighScore Plus. (2) Maybe your candidate patterns that you tried converting to phases do not contain information regarding the atomic positions of each phase. If this is the case, you can't refine the phases based upon those candidate patterns. Please see this video for more detail (kzbin.info/www/bejne/r3i0dYt5jaqUp7s).

how can we determine each peak is correspond to which planes???
@IAMMDiffractionFacility Ай бұрын
If you have analysis software such as HighScore and a database of reference patterns, that is the easiest way. I have a phase identification video showing that. Once you identify the phases, you can find the peak list in the reference file, and that will tell you the (hkl) for each of the peaks. Otherwise, you need to index the peaks manually. I have a video for how to do that for a cubic system, but it gets more difficult as you move to lower symmetry systems.
@hashemsaaed4929 Ай бұрын
@@IAMMDiffractionFacility Suppose I have the reference values of hkl for both phases... but their numbers are very close like SNO2 and Zno... How do I distinguish between them and what is the comparison mechanism? Do I compare the first two peaks in the references with the first one in the sample and the closest one is the correct one? Then compare two peaks in each reference and compare them with the second peak? And so on? I am facing a big difficulty in that. Can you help me?

@IAMMDiffractionFacility Ай бұрын
There are a number of reasons this could be. Maybe the refinement changed the lattice parameters too much, maybe the sample height displacement changed too much, maybe the sample has a lot of texture (causing the intensity fits to match poorly), etc. It is really difficult for me to say without seeing the refinement results (raw data vs. calculated pattern).

When you are on the chemistry tab selecting which elements to focus on, please look toward the bottom of the window. First make sure that the minimum number of elements is 1 and the maximum number of elements is something large (you can make it 100 if you like). Directly beneath that, you should see "Resulting hits: **** patterns of *****." Can you tell me what numbers yours shows? For example, in the video, it showed 1428 patterns of 412099.

This tube alignment method assumes that the incidence beam divergence slit and the detector's central pixel are almost perfectly aligned in one line with the goniometer's center. Are the correct and reproducable positions of the slit and detector guaranteed by manufacturer forever or they are adjusted by a user somehow before the tube alignment?
