How XRD identify different phases in a material?

[@ahmedmalik9974]

Sir thank you so much for uploading such kind videos before seeing your video's we were at zero about all these thing .I am watching all your play lists. Thank you so much

[@qamarwali]

I'm glad to hear from you. I am just doing a little to help and educate students. You are welcome 😊

[@g.praveena1736]

Thank you for your valuable information, sir. I am still confused by my manuscript's plagiarism report. Because the reference part shows nearly 20% plagiarism. Will you please explain to me why it's happened and how to avoid it? I am waiting for your valuable response, sir... Please reply as soon as possible...

[@qamarwali]

The simplest way to find the similarity index is: Once your manuscript is ready, then make a separate copy with a different name. Then, delete all the references available at the end of the manuscript. Then, upload it to turnitin.

Sir your videos are really beneficial for students. kindly make a series on Material Synthesis Processes.

[@qamarwali]

Noted with thanks 😊. Sure, I will keep posting videos on these topics.

Thanks Sir for such a great videos. Sir I have question. Jab ham journal ma paper submit krta h to Kuch professor ko recommend krna hota h. Kia ham un professors ko pahla sa agah kr skta h. Jaisay ma apka name as a recommend kr rha hon for review k lya. Thanks Sir

[@qamarwali]

Yeah, we are recommending reviewer names 3 to 5 when submitting a manuscript to any journal. Sometimes, the journals send our manuscript to the reviewers we provided, but it is not necessarily that the editor will send to only those reviewers. Quality and high impact factors journals editor will send to others because they already have other reviewers name in their system. Moreover, it is not a good approach to keep reviewers' names you already know.... because it is not an honest way to publish your work..... *Yes, many researchers are doing this practice* *Summary* In most cases, the editor will send your manuscript to the reviewers you provided during the submission. Good luck!

Aoa Sir. Sir how can we open supplementary data files. Because when I click on the link that is given for supplementary data, it again opens that article which I already have open.So please, how can i open it. Jaxak Allah for your channel

[@qamarwali]

May be the authors or the journal have not uploaded the supplementary files with the main article. The second option is just to write an email to the *corresponding author* His or her email is already there in the main article. Just ask for the supplementary file, and they will provide you. If you are still stuck, then let me know !

[@chemistrylearning2116]

Sir this is a supplementary file link 10.1016/j.ceja.2020.100040 But when I click it reach to same article that I have already opened. And at the end the same link is present. This does not occur for one this, this situation is the same for all articles. Actually the thing is that I do not know how to open a supplementary file. Kindly if you can make a small video, if is it possible.

[@qamarwali]

I have checked it. It is there on the left side in the *Outline* with the name *Appendix. Supplementary materials* Just click on and it will take you to the word file with the name *Download : Download Word document (1MB)* Just above the references. Click and it will download!! I did it and it works!

[@chemistrylearning2116]

@@qamarwali Thank you sir It works

[@emaneman8532]

Sir EIS spectra give us which information?

[@qamarwali]

EIS basically gives us the charge transport and transfer mechanism in the device. Also capacitive behaviour at different interfaces......

[@ahmedmalik9974]

Sir plz make a video on supplementary data file how can we add it in article.

[@qamarwali]

When you are uploading files on the main website of journal. There are options to upload documents such as cover letter, main manuscript, highlights, ....... The supplementary data file is also on that list.

[@ahmedmalik9974]

JazakAllah sir Sir if you found any littile thing that students should know kindly make video we watch all. Thanks

[@shushantrajput3379]

I watched your all previous videos those are related ....also installed high score plus from your Google drive link....

[@RimshaAqeel-kd3mx]

Sir I also want to install an Expert high score because I need it. Kindly you share your Google drive link for Expert high score. Thank you

[@shushantrajput3379]

I hope this message finds you well. I am writing to seek your expertise regarding an XRD pattern analysis predicament I'm currently facing.I have recently obtained an X-ray diffraction (XRD) pattern, and despite my efforts, I am unable to conclusively identify the phases present in the graph. The complexity of the pattern has posed a challenge for me, and I believe your experience and knowledge in this field could greatly assist me in deciphering the phases accurately. Would you be available to provide guidance or assistance in interpreting the XRD pattern? I am more than willing to share the data and any relevant information to facilitate the analysis process.Your expertise would be invaluable in resolving this matter, and I sincerely appreciate any help you can offer.Looking forward to your response.

Thanks for your comment ❤️ Look, I have already explained in the video and also kept the same text in the description. There are three places where you can confirm the phases of your synthesized crystallite materials. 1. Commercially purchased databases The International Centre for Diffraction Data (ICDD) provides the diffraction data and maintaining powder diffractions file (PDF). ICCD, previously called the Joint Committee for Powder Diffraction Standards (JCPDS). The data is available in different names. Two of them are below *PDF 1* lists d-spacings and relative intensities of the large number of materials. *PDF 2* all data indexed such as cell parameters, the chemistry, and density of the materials. *These PDF available on ICCD are not free* You have to purchase it. 2. Online open access databases There are online free sources such as crystallography.... and just look for the *CIF* file. Hopefully, you will find some reference here and can match your XRD pattern. 3. Literature In many cases, very newly developed materials will not yet appear in these databases, so the best place to find these spectra is in the original publication. So, search the XRD pattern in the research papers. PS: When you started synthesising your materials, there must be some initial starting paper you have followed. When we do something new, we basically follow the literature and do some amendments.....

[@emaneman8532]

Sir kindly make a video on EIS(Electron impedance spectroscopy). I will be very thank ful to you sir

[@qamarwali]

Sure. I will make a video on it.

[@MuhammadBilal-hd8zr]

Sir, please make videos on the characterization of perovskite solar cells.

[@qamarwali]

[@marasini]

Sir, can I get your email id , I have to ask few question regarding XRD

[@qamarwali]

Thanks for your comment ❤️. I rarely check my email. However, I can respond to any questions related to the topic. Please feel free to drop your query here in the comment.
