Good sir
Thank you 😊
Thank you for this valuable information. But what to do if peaks of cyclic voltammogram is not distinct..means peaks are very diffused.
Whic Semi circle in double semicircle gives Rb value to calculate ionic conductivity
In the case of a double semicircle in a Nyquist plot, the bulk resistance Rb is determined from the high-frequency semicircle, as it corresponds to the material's bulk properties. The low-frequency semicircle usually represents grain boundary or electrode interface contributions.
Thank you very much. Can you please do this in EIS software
The bulk resistance is taken for semi circle value right for calculating ionic conductivity? Can you please confirm. I have read that the high frequency side is taken as Rb.
"Yes, you are correct. The Rb is typically determined from the high-frequency intercept of the semicircle in the Nyquist plot. This value is used to calculate ionic conductivity.
0.5 u got for intercept not slope sir but u mentioned as slope.which one we have to take.i have taken slope
Sorry for the late reply. Yes, you need to take the slope only. I mistakenly took the wrong value earlier. I will correct it. Thank you.
Great job sir keep it up👍
Thank you 😊
This is doing nothing but leading to the mark of the beast 666

How to have "Asymmetry Least Squares Smoothing" in Baseline Mode?
Open the Baseline Tool Go to the "Analysis" menu. Select "Peaks and Baseline" → "Baseline Detection and Removal". : Configure Baseline Settings In the Baseline Detection dialog box: Set Baseline Mode to User-Defined (to manually configure smoothing parameters). Choose ALS (Asymmetric Least Squares) as the baseline fitting method (if available in your version of Origin).

My data showing decreasing value of i/v^0.5 vs v^0.5 plot what can i do
If the trend decreases, it may indicate that other processes (e.g., adsorption, kinetic limitations, or resistive losses) are influencing your system. If the system is not diffusion-controlled, the decreasing trend could reflect increasing charge transfer resistance. For Alternative Approaches Plot the data differently (e.g., i vs Root V ) to verify the trend.
I Vs root V is increasing graph After taking ratio of i /root v it is decreasing

Is smoothing and background separation same?
Might be different if we talk about background correction.
@@Your_Research_Buddy If I do baseline subtraction, does that count as background correction?
Sir, kindly tell me how we plot this graph in origin .plz ..
Okay I will upload video on very that.
How to determine the resistance from the grain resistance and grain boundary resistance from the Nyquist plot?
Thank you for watching. Generally, for materials with grain and grain boundary contributions, the plot typically shows two semicircles: High-frequency semicircle corresponds to grain resistance and this belongs to grain resistance. Low-frequency semicircle corresponds to grain boundary resistance both grain as well as grain boundaryresistance. To fit the data for precision: Use an equivalent circuit model (typically a combination of two 𝑅−𝐶 R−C circuits in series.
Why you skipped the plotting session at the end? Why can't you show that too??
Thanks for your feedback! The graph plotting part is a straightforward process and doesn't add much value beyond what's already explained in the video. Including it would make the video unnecessarily lengthy. However, if you're facing any issues with plotting, feel free to ask, and I’d be happy to guide you!
@@Your_Research_Buddyyez, include this part and reupload the video as you did the other
Sir, Kindly tell me in your previous video,you wrote the formula of cv without being divided by 2 in numerator. So it's still confusing which formula is correct, for 3 electrode and 2 electrode of battery and supercapictor
