Hi master, the electricity flows in the same speed in the centre of a cable and on the outer surface of the cable I am curious

principally, there should be no issues as it is a complete version. However, if you're facing this issue, you share the screenshot of the graph in MS Word with me at [email protected]. I'll have a look at it. Thanks

Sir how many maximum phase quantification cam be made ? As i have 6 phases in my data
@SAYPhysics Күн бұрын
In GSAS-II, there is no strict limit on the number of phases you can refine. However, practical constraints arise from computational power, data quality, and refinement stability. Thanks

Sir, if v=w/k which is a phase velocity, and doesn't able to carry energy (standing wave). Can we say it traveling wave?
@SAYPhysics Күн бұрын
No, a standing wave is not a traveling wave. A traveling wave carries energy, whereas a standing wave results from the interference of two waves traveling in opposite directions, leading to fixed nodes and antinodes. The phase velocity describes the motion of wave phases, but energy transport is determined by the group velocity. Thanks

How do I find a stacking fault?
@SAYPhysics 5 күн бұрын
Stacking faults in XRD data cause peak broadening, asymmetry, and intensity variations. Methods to analyze them include Williamson-Hall plots (strain effects), and Rietveld refinement (faulted models). Thanks

Shall we calculate the FWHM values for individual peaks from LaB6 data then take its average value of FWHM and then subtract that Average FWHM values from individual FWHM value of the non-standard sample? Can we do like this?
@SAYPhysics 8 күн бұрын
No, it is not correct to subtract the average FWHM of LaB6 peaks from individual FWHM values of the non-standard sample. The instrumental broadening (βi) should be determined for each peak of the LaB6 standard individually, as instrumental broadening varies with 2θ. Then, for each corresponding peak in your sample, you should subtract the respective βi value (calculated using the standard) to get the corrected broadening. This ensures accuracy in determining the true sample broadening. Thanks

@@SAYPhysics Thanks for replying quickly. Please also tell me that If I am getting FCC peaks at 43.607, 50.831, 74.786, and 90.803 so what peak positions I should consider for LaB6 sample? Can I consider these mentioned peak positions of LaB6 sample? : 43.493, 48.944, 75.833, 87.783 (or 95.664)?
@pankajojha5075 8 күн бұрын
Also, sometimes when I am individually fitting the peaks for LaB6, I am getting an error that "Fit did not converge. Maximum iteration setting of 400 was reached." I am getting this error for peak positions at 43.493, 75.833, 87.78. Please suggest me what to do in this case?
@SAYPhysics 8 күн бұрын
@pankajojha5075 This is due to your fitting parameters or restrictions you have put on certain parameters. It has nothing to do with the number of iterations.
@pankajojha5075 8 күн бұрын
@@SAYPhysics If am selecting all the corresponding peak positions of LaB6 at once and then I am fitting it then the fit is getting converged. So can I use this FWHM data? Or I have to do it individually only?

Dear Sir, My FWHM decreases with increasing 2 theta. The fit is linearly downwards with negative slope. Could you pls advise?
@SAYPhysics 14 күн бұрын
A decrease in FWHM with increasing 2θ often indicates the influence of instrumental broadening or crystallite size effects dominating over strain. Ensure proper instrumental broadening correction and verify your data fitting method. If the slope remains negative after corrections, it may suggest negligible strain in the sample. Thanks
@awesomescienceworld1236 13 күн бұрын
@SAYPhysics I've understood, Sir. Thank you very much for your reply. I've taken the fwhm values from my rietveld refinement. Could that be a reason?
@SAYPhysics 13 күн бұрын
You're welcome! Yes, FWHM values from Rietveld refinement can be influenced by the refinement model and how it accounts for instrumental broadening and sample effects. Ensure that the instrumental parameters are correctly modeled, as inaccuracies there could affect the trend. If the refinement accurately represents your data, the negative slope may still indicate minimal strain in the sample. Thanks!

But even after some practice, I'm not satisfied with the refinement because say for eg (I haven't refined, one of xyz/Biso param) I get chi2 to be 1.2 - 1.6 etc. How do I master this technique, is there any suitable material for me to refer to?
