@leilapani3488 2 жыл бұрын

thank you so much for such great job , please continue it, if you can please explain about warburg and the pseudo-capacitive behaviour in circuit.

@Pineresearch 2 жыл бұрын

Hello Leila, we are glad you enjoyed the video. Describing warburg and pseudo-capacitive behavior is probably a topic for another lengthy video. But in short, a warburg element is used for the impedance associated with diffusion, which one can observe with the 45 degree tail on the Nyquist plot in the low frequency region. Constant phase elements (CPE's) are circuit elements used to describe pseudo-capacitive behavior. A capacitor is two charged parallel plates separated by a dielectric. Sometimes in electrochemical systems you'll get things that are almost like a capacitor, but not entirely...because it's electrochemistry :D . So it's hard to circuit fit an electrochemical system to an ideal capacitor because almost nothing in electrochemistry is ideal, so we use a CPE instead. I hope this was helpful. Stay tuned for more!

@LuizEnger 2 жыл бұрын

Thanks for the video! Would really appreciate another one going deep into circuit fitting.

@Pineresearch 2 жыл бұрын

Thank you Luiz! Actually, Dr. Neil Spinner with Pine Research does a somewhat regular advance EIS webinar that covers circuit fitting in more detail. There a few KZfaq videos from us on the subject, like EIS of a perovskite film kzfaq.info/get/bejne/rc-oo5ahsNyvfZc.html and EIS of a PEM water electrolyzer kzfaq.info/get/bejne/mshlq92msbCyZIU.html. We've got a few more in the works, but follow us on twitter and check out our website for the next time we do an advanced EIS circuit fitting webinar.

@fencros7y919 2 жыл бұрын

Thank you for your good explanation. Recently I was figuring out how to use EIS to calculate the diffusion coefficient. In many literatures the researchers just simply carried out a EIS test and then used the equation D=(R^2*T^2)/(2A^2*n^4*F^4*C^2*σ^2). I feel confused about what is semi-infinite diffusion, the physical meaning of warburg coefficient, in what circumstances can I use the equation. What is the differences between soluble analyte (analyte diffusion) and solid analyte (counter ion diffusion)? Maybe too many questions haha.

@Pineresearch 2 жыл бұрын

I completely understand. These are great questions, and might be a bit too much to address in a single KZfaq comment. Shameless plug aside, Pine Research is offering a free EIS webinar series pineresearch.com/eis-webinar-series-registration/ it's run by my colleague Dr. Neil Spinner, and I think you'd get a lot out of it. To address questions about warburg coefficients, semi-infinite diffusion, etc he will probably talk about those in the later parts of the series (part 3, 4, and 5). However, I would encourage you to attend the whole thing. I hope this was helpful.

NeverthIess, I have one question regarding this EIS, I hope You will address my doubt. I have seen a video in you tube where Mott Schottkey plot was done from EIS data. I have used the same method to plot Mott Schottkey from EIS, but in EIS data, no potential data column was given, which is required to plot Mott Schottkey, instead a frequency column was given. I want to know if you have any idea how EIS data can be used to plot Mott Schottkey. Thank u

@Pineresearch 2 жыл бұрын

Thank you for your kind words. I'm no expert at Mott-Schottky, my colleague Dr. Neil Spinner prepared the advanced EIS webinar on the topic. But you are correct, Mott-Schottky requires a column of potential data as well to perform the analysis. What that means is you will need to perform EIS experiments centered around multiple potentials. So it's a fairly long experiment. Does that make sense?
