In conversation with a Geologist from Nepal on XRD Data analysis
In this insightful video, I had the pleasure of guiding Amrit Marasini, an M.Sc. Engineering Geology student from Tribhuvan University, Nepal, on the entire process of XRD data analysis. We cover essential steps like sample preparation, data simulation using VESTA, downloading CIF files from the COD website, and performing Rietveld refinement using GSAS software to determine weight fractions. We also discuss the importance of literature review and building connections with scientists and professors in the field. This video offers valuable insights for students and researchers diving into XRD and geotechnical studies.

because i got only binge energy ,data,fit data only
Hmm
i want to.know from where you take data of p1 p2 and bakg
Use xps peak fit software to do the deconvolution and then use origin software to plot it. The two peaks are after the deconvolution. Original data is only binding energy and intensity.
please tell.me how you gave different colours of this peaks
Hmm
In my data x axis is not in equal interval but in this matrix method this takes equispaced values so how can we resolve this or any other way to plot 2D contour plot
Not aware of that…sorry!
@PhDzzz66 thanks for the reply I have done .

Welcome
OH MY GOD, YOU JUST SAVED MY LIFE! Literally, I was going to crawl under the bed and stay there, because I was at the end of my rope not being able to figure out how to create a table to go into my book for formatting for publication, and I didn't want to pay someone to do something I should be able to do myself!! I have been trying every thing I could imagine, going to Reddit and Quora and NOTHING was working!!! Finally, as I was about to give up today, I found your video and BAM!!!!! These tables look amazing in the editor - finally! THANK YOU!!!!!!!!!
OMG !
Hello , can u please make a video on Graphene monolayer +MnO2 monolayer (hexagonal) 2D structure ?? I will be sincerely consider your help

Not sure…please check the software
Thank you
Welcome 🤗
If I want to creat a XRD spectrum of Bi2O2Se using VESTA, should I use the structure before or after these adjustments.
Before the adjustment
Could you please make a video on how to make Mn02 2D structure??
You should be able to do that by following the steps shown in this video.
How to measure the distance between those two layers?
There is option in the VESTA to do that. You can find it in the left side of the screen.
Sir, please explain what is the meaning of negative and positive slopes in the W-H plot. and how we can correlate the strain of a material with electrochemical data.
Interpretation of the Slope 1. Positive Slope: • Indicates tensile strain in the crystal lattice. • The lattice is stretched, resulting in peak broadening associated with an increase in . 2. Negative Slope: • Indicates compressive strain in the crystal lattice. • The lattice is compressed, leading to a reduction in the spacing of crystal planes and corresponding peak broadening. Physical Meaning • Tensile Strain occurs when the crystal lattice is pulled apart, often due to thermal expansion, stress from mismatched substrates, or other external factors. • Compressive Strain happens when the lattice is squeezed, which may arise from external pressure, epitaxial constraints, or shrinkage during cooling. In summary: • The sign of the slope ( or ) helps identify whether the crystal lattice is under tensile or compressive strain. • The magnitude of the slope reflects the degree of strain present in the material.
Thank you
Welcome
Could yo show to me, how to make a vacancy structure in graphene for example. And could you please give me some idea to add some atom to the structure?
If you need it just for the schematic presentation then first draw the structure using VISTA and then use PowerPoint to add or remove atoms.
sir. stacked y-axis is didn't work for me. what i do
Select columns again and use it in plot-basic2d-stucked lines by Y(almost last button in list)

Please explain how to make composites oxides in vesta, thanks
There is no straight answer and you may need to play around within VESTA software and use PowerPoint to do some editing. This is just for the drawing a cartoon and not for the actual calculation.
thank you for this one.

USEFUL
Thanks
Hi sir, can you tell me one thing here.. in this your plotted values didn't coincide with the straight line right? then is this correct? please clarify
You can mention the chi2 value to define the fitting quality while discussing the outcome of fitting results.
I need free originlab software
Mee too 😀
Hi; I don't have this line in my origin; what can I do?
Which line are you talking about?
Dear Bro. It is really great video. Will this approach work for hexagonal crystal structures as well for example AlN like systems
That’s need to be dig-out
I think you are missing out the point that while simulating heterostructures, we need to ensure that both phase must have the similar lattice constants to avoid lattice mismatch. Therefore, we must multiply each one of them by a factor to attain the same. Please have a look at the following tutorial th-cam.com/video/GcRWRLTSj-w/w-d-xo.htmlsi=mUfo1vEnEyAmvJ8w. Thanks!!
Thank you for the explanation and will take a look into it.

Rietveld is possible in organic field...yes or no???....sir
Yes, the Rietveld refinement method can be used for organic materials, though it is more commonly applied to inorganic crystalline structures. In the case of organic materials, especially those that form crystalline solids like pharmaceutical compounds, molecular crystals, or polymers, the method can still be applied effectively. However, organic materials often have more complex structures, lower symmetry, and larger unit cells, which may present challenges in refining the data.
Wonderfull
Thanks

*Typically, the I(L2)/I(L1) value is expected to be around 0.5 for most X-ray sources, like Cu Kα radiation. However, if you're seeing a refined result around 0.01 (as shown in this tutorial), it could be due to a few reasons: Refinement Process: The refinement might have overfit the data or introduced too many free parameters, leading to an unrealistic value. In such cases, constraining the I(L2)/I(L1) value to 0.5 often helps to achieve a more reasonable result.z Instrument Parameters: A mismatch in the instrument model or profile settings could affect the intensity ratios. Double-checking the calibration and profile function can help refine this correctly. Data Quality: A low signal-to-noise ratio or peak overlap can also cause this deviation. Ensuring high-quality data collection can often resolve this issue. I'd recommend fixing the I(L2)/I(L1) value to 0.5 during refinement and observing how it affects the fit.*
Thanks Buen video
Glad that it worked for you!
Thank you so much, this is really helpful
Glad that it worked for you!
Hello, could you please explain again why the refined result of the I(L2)/I(L1) parameter in the instrument settings is around 0.01 (I learned from other tutorials that this value should be around 0.5)?
Thank you for your question! You're absolutely right that the I(L2)/I(L1) value is typically expected to be around 0.5 for most X-ray sources, like Cu Kα radiation. However, if you see a refined result around 0.01, I'd recommend fixing the I(L2)/I(L1) value to 0.5 during refinement and observing how it affects the fit. Let me know how it goes, and feel free to reach out if you have further questions!
Thanks Dr.Gandhi for your wonderful explanations. I would like to know, how I can plot the exported data from vesta simulated XRD and plot it in Origin ? I tried but failed, can you upload a video on this ? Thanks in advance

Hello! Thank you. I did not know about this software. I have used Origin software to deconvoluted but is difficult do it. I have some question. What are the most important parameters to be taken care of in order to deconvolute? How important is it to maintain the same curve width in each of the components that adjust the envelope? Could you suggest any bibliography that could help me with deconvolution of Raman spectroscopy?
For me, the shape factor was the one parameter I used take care of vile using Voigt function for the deconvolution. I am not sure on the curve width. The peaks are originating from different types of atomic vibrations in the samples and due to which I keep width and center as a free parameter. I don’t have any specific information of the bibliography for Raman spectroscopy.
