great video! watched several videos before this and didnt understand until now :)
We're really glad that this helped. EIS is certainly a complicated subject, and we tried to make it as simple as possible.
This is so complex but your explanation helps me a lot to understand it
EIS is probably one of the most complex areas of electrochemistry, and electrochemistry itself is pretty complex. We tried to make the introduction to the field as easy to understand as possible. But it will take some time and experimentation to really understand it. Thanks for watching!
Thank you for your explanation! As a beginner in this field, i really need this kind of videos to help me understand this field.
You're very welcome!
Excellent explanation! Thank you!
Of course! I'm glad you liked it!

Thank you!
Thanks for the video! Would really appreciate another one going deep into circuit fitting.
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 RUclips videos from us on the subject, like EIS of a perovskite film ruclips.net/video/wixp3pKvKMc/видео.html and EIS of a PEM water electrolyzer ruclips.net/video/db5xzuLJN4Q/видео.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.
@@Pineresearch Thanks a lot! I'll definitely look into those!

It's very helpful thank you so much
Most welcome 😊
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.
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!
great video! thanks a lot!
We're glad you enjoyed it!
Great video, thanks
Glad you liked it!
Really great video !
So glad you liked it!
Best overview of EIS I ever saw. Better than my university professor's
We are glad you liked it! I would also say that university professors can get caught up in the weeds of the technique, but we prefer a simpler and more accessible approach to the technique :)
@@Pineresearch Speaker is very well learned about the technique
@@dimple7267 Thank you! I did a lot of preparation for the video and consulted several colleagues to make sure the content was accurate :)
awesome , informative and impressive explanation!Thanks for sharing--(I''m a che student from asia)
We are very glad that you enjoyed the video and thought it was helpful. We are based in the US, so we are glad we provide some transcontinental help :)
Very helpful!!!
Thank you!!
Life saver, Thanks!
Awesome! I'm glad the video was helpful :)
Excellent video 👏👏
Thank you!!
great class.
Glad you enjoyed it!!
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.
I completely understand. These are great questions, and might be a bit too much to address in a single RUclips 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.
thank you it's helpful in my post graduation project 🙏
We are happy it's helping you for your post graduation project. EIS is challenging to learn.
really thanks!
You're welcome!
Thank you!
You're welcome!

You're welcome! Glad you liked it.
thank you very much..
You are very welcome!
Thank u for providing such a knowledgeable and important video in free of cost. The way you explained everything, is really comprehensible. 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
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?
Just amazing
Glad you liked it!
that was great.
We are glad you liked it!!
thank you sir
Most welcome
Ver good explanation
