Thanks for the appreciation dear 😊 I'm sorry that I'm not an expert in your required field.

You're welcome dear

Thanks dear 😊

Thanks dear 😊

Yes, you're right. It's good for spherical and spheroidal NPs. We're working on it to include other morphologies like nanorods, nancubes, and nanoflowers etc. Thanks

@@SAYPhysics Thank you so much.

@aminrashidi1581 You're welcome dear

Glad to know that it was an informative. Thanks for the appreciation dear 😊

You're most welcome dear 🙏

Good to know dear. Thanks and Aameen

Wa Alaikum Assalam! Yes, for an amorphous material with an indirect allowed transition, it is important to plot \((\alpha h u)^{1/2}\) versus energy (\(h u\)) to determine the band gap accurately. This approach corresponds to the characteristic absorption edge of indirect transitions. Thanks

I plotted both the graphs for direct as well as indirect but as mentioned already that my material is having indirect band gap and I got perfect slope from the direct band gap graph...so what to do?? Should I opt for the direct or indirect??

@@SAYPhysics JazakAllah sir! May you live long and happy life Ameeeen

I will suggest to first check your calculations and then relate it with a trustworthy literature. Thanks

Thanks and Aameen dear.

Please check your provided institutional email on which you'd have received the required information. Thanks

Thanks for the appreciation dear. It's good to have you as the first commenter always. Share it too dear

@@SAYPhysics Your words are honor professor. Regarding sharing, I have done so. Sorry for my late reply.

You are my favourite teacher

Thanks dear 😊

Thank you for your detailed feedback. You raise valid points about the accuracy of the manual marking of crystalline regions and the importance of peak fitting to avoid overestimating crystallinity. Subtracting the amorphous area first is indeed a more accurate approach. However, this is the usual way of calculation. While it's better to consider your suggestions and provide a reference for the method used in. Thanks again!

Yes, you're right. Thanks for the input ☺️

Thanks for your valuable input dear 😊

"Introduction to Electrodynamics' 3rd ed. By DJ Griffiths. Thanks

Yes dear. You may email me at sayphysics@gmail.com. Thanks

@@SAYPhysics thankx sir

@user-qt4hd5dr7v welcome dear

I don't know what do you mean by the spikes? Would you like to mention the angles at which you are observing the spikes. Thanks

Thanks for the appreciation and positive comments. Yes sure. I'm planning to cover all these tutorials. Stay tuned.

@@SAYPhysics Thank you.. Okay, my dear, waiting for you

@ms.cmozahimazizalamery7880 you're most welcome

Thank you for your question! After baseline correction, the y-values (intensity or transmittance) can indeed change slightly. However, this adjustment is typically necessary to remove any background noise, ensuring that the data more accurately reflects the true signal. The changes in y-values shouldn't significantly affect the analysis as long as the baseline correction is done correctly. The corrected data should provide a clearer representation of the underlying features you're interested in. It's recommended to plot both actual and smoothed profiles.

@@SAYPhysics thanks！It helps a lot!!

@franksimon-jh9ls you're welcome dear

You'd have received your own product key on the official (institutional) email that you'd have provided during the download process. Thanks

Write in Google 'originpro download, it will guide you to the download page where you click your desired download link. Thanks

Thanks dear

Thank you for your comment! Generally, acceptable values for reliability factors like Rp, Rwp, and Gof can vary depending on the complexity of the sample and the quality of the data. An Rwp value around 8% can still be acceptable, especially if the data is complex. However, lower values (below 5%) are generally preferred for higher precision. It’s important to consider other factors like the goodness-of-fit (Gof) and the visual quality of the fit when evaluating the refinement.

Thanks dear

Welcome dear

You're right. Thanks

Yes dear

Right dear. Thanks for your appreciation. Sure, we will cover all the courses IA.

Thanks for the appreciation dear 😊 Please share it with others too 🙏

Thanks dear

You may ask for extension to Originlab, if they accept. Or can install the next year version. Thanks 👍

Yes dear. From this Monday, upload will start in a new playlist Quantum Mechanics -II. Thanks

Please check the video description, I have provided link for downloading all the required files including the prm file. Thanks

Thanks for your contact. You may post your question on a specific video or any relevant video. I respond to it immediately. This way the response is available to all. Thanks

@@SAYPhysics Ok sir I am bs physics student second semester please recommend me best book for heat and thermodynamics and electricity and magnetism for theory

@@greatxd3063 For your BS Physics second semester: Heat and Thermodynamics: Zemansky & Dittman - Heat and Thermodynamics: A solid introduction to thermodynamics. Schroeder - An Introduction to Thermal Physics: Clear and engaging, covers thermodynamics and statistical mechanics. Electricity and Magnetism: Griffiths - Introduction to Electrodynamics: Widely used, clear explanations. Purcell & Morin - Electricity and Magnetism: Advanced, with a strong emphasis on physical understanding. Thanks

@@SAYPhysics Jazak'Allah sir ji

@@SAYPhysics Sar you are doing so great in RUclips but please upload the lectures of BS physics electricity and Magnetism course because you are uploading or you have uploaded the lectures of electrodynamics but not the lectures of electricity and Magnetism because for BS physics to understand electrodynamics carefully he or she should have understood the concepts of electricity and Magnetism first

Thanks for the appreciation dear 😊 Here's the website for WinXPow, however, it's not free. stoe-winxpow.software.informer.com/ In case you would like to perform XRD data analysis for free, I have the following playlist of tutorials based on GSAS-II.

Thanks dear

Thanks for the appreciation dear 😊. Share it with others too.

Baseline correction in X-ray diffraction (XRD) data is important because it removes background noise and artifacts, which can obscure or distort the true diffraction peaks. This correction enhances the accuracy and reliability of the analysis by ensuring that peak intensities and positions are correctly identified, leading to more precise characterization of the material's crystal structure and phase composition. Thanks

@@SAYPhysics thanks so much！

@franksimon-jh9ls you're welcome dear

Please see the following videos for doing it for many curves at once. Thanks ruclips.net/video/1ZiDJ3NZnL8/видео.html ruclips.net/video/WX_X3XlbKRA/видео.html

Usually the time is 3X the actual recording. Recording+Editing+Sharing. The lecture preparation time isn't included in it. Good luck for your ambitious. Thanks

Thanks dear.

You're right. In the next video in the same playlist, I have added audio to this video. Thanks 👍
