Very helpful. Got a lot out of this. Never seen the symmetry factor explained like that.

Very insightful and straightforward

I want to have a video derivation of Tafel and Butler-Volmer equations. Also, this is really helpful! Thank you for making this video

@zimmerpeacock9703 Год назад

Definitely will

@aurorali323 Год назад

This is great. I finally understand now.

@zimmerpeacock9703 Год назад

I know exactly how you feel, when we teach we are also remembering the struggle to understand - M

This is useful. More detailed explanation of the same for the case of corrosion would be helpful

@zimmerpeacock9703 Год назад

I would like to do more on corrosion :)

Very interesting topic ! Many students find this very difficult to understand

@zimmerpeacock9703 Год назад

Thank you - I agree, I think the topic is taught in isolation from the rest of the topics, so what I want to do is show how everything is connected. thank you for the feedback

very useful session can you make video on derivation of Buttler Volmer equation and Tafel equation

@zimmerpeacock9703 Месяц назад

I do read these comments and I do put them on the to-do list, thank you -

Thank you Zimmer

Thank you for the video. I have some electrochemical data, I was able to do a fit of the Tafel equation; however, I noticed my alphas were very small, I think around 0.02, any suggestions?

@zimmerpeacock9703 2 месяца назад

You may have made one mistake, for example where something is 10 and you have put it in as 100. This happens a lot :)

@j.t.4652 11 месяцев назад

Thank you for the video! Could you go deeper into the Tafel plot and also the weaknesses of this evaluation method? In my group some people have raised concerns about the meaningfulness of Tafel plots.

Hi, can you do calculation from CV data for HER reactions, like tafel slope, ipc and ipa etc if possible
