does the video based on Bard A.J`s book?
excellent
very informative
Thanks for all the content Jill. When talking about dopamine, am i correct to take it that the analyte is always either in a state of being adsorbed or solvated then? and that being solvated is the same as being in solution. and everything has to be adsorbed to the WE for any faradaic process to occur. Im having an issue with nucleic acids making my ferricyanide CVs flat when added in and i cant figure out a workaround. Im thinking something is probably happening to the WE and preventing the FeCN from adsorbing.
Thanks for addressing the weird peak that forms from an increase in current that appears on the beginning of the backscan. So it means that in your example, that peak is adenosine actually still being oxidised?
Why the video called chronoamperometry, but the video explains more about DPV?
Maybe you do not see my comment but in 2024 I am seeing your video still the information and your presentation performance is great wish you all the best I hope and can contact you for some information . regard
Thank you very much. Can I get electrochemistry references for beginner student please?
The best place to go is likely Electrochemical Methods by Bard and Faulkner for techniques like these.
Excellent, thank you very much
Can you do something about the adds, 6 in a 20 minute video, usually halfway through explaining stuff is pretty awful
why potential shifts occurs ?
i love how you explain it . Thank you for you lecture/ presentation !!
I know this video is super old, but I really feel like I need to tell you that your explanation of the cyclic voltamogram made me understand my entire research project. Thank you very much.
Poggers what a gamer
Can anyone recommend me the book regarding this
I love you a lot I love this video a lot. Thank you so much. It is very useful for me. !
yri
even the auto-translation doesn't understand you so please speak clearly with one level of voice because your sound is just as double layer's potential it drops of as you completing the sentence.
nice video, thanks for the explanations and thanks for sharing! best wishes from oldenburg in germany!
perfectttttttttttttt lecturrrrr
I adore electrochemistry with you. Thank you teacher. I’m so lucky to watch ur videos. Best regards,
Hi vrooooop
Thanks this was very helpful. Do you mean to say the capacitances are in series at the end? Your schematic and total capacitance calculation both suggest as much.
Really nice explanation of CV!
Why is the electrode area small when analyzed by Voltammetry ?
Great content, I subscribed! You should use promosm it will help you grow your channel.
I think you meant capacitors in series. The total capacitance of capacitors in parallel is a sum of the capacitances of each of the capacitors involved. Great class.
Thank you, I started to undertand thanks to this video.
Thank you - an excellent explanation!
Thanks. It was helpful!
Thank you so much Professor Venton for uploading this content!
I cant hear clearly! Maybe the microphone is not adjusted well. But I really appreciate the effort, it's helping me a lot in understanding Electrochemistry! Thanks!
Is cathodic or anodic current positive?
Thank you so much Professor Venton for making this video! It's great to know more about your department!
Great! Thanks
Thanks for this video! I wanted to know if you have also covered other Chapters of Bard and Faulkner here on your channel?
thank you SO MUCH for making your electrochemistry lectures public
please get a better microphone :(
Thank you teacher... its really help... I'm waiting for another education videos.
thank you! Basics came back after watching your video!
I loved your explanation....keep it up. and thanks
Hi mam.. I am finding your videos very helpful for understanding the electrochemistry topics. Thank you so much for your efforts. I have a small suggestion. It would be really great if you can manage 'Uumm.. uumm..' while speaking as it was quite disturbing to listen to the class with that. I mean no offence. Thank you once again.
Great Video! I always wondered why in CV they state voltage as a negative eg(-0.4V) is that meaning milli volts? Or is the negative reading related to the initial state of charge of the cell prior to charging for the first time? Or is it related to the reference electrode? Stupid question I know.
A great lecture, first i was reading your 2020 paper and then saw your class on youtube without knowing it was the same autor, both are awesome :)
Thank you for this. I'm horrible at electrochemistry, but this is easy to understand. I feel like I can finally have an intelligent conversation with my PI after watching this.
Great video! Just to make one thing clear to anyone who may be confused. At 3:11 you show a vertical slice through the CV while you actually mean a vertical slice through the color plot.
Very clear series - Thanks
I am an electrophysiologist, and I absolutely DID NOT understand what she's trying to say. Is there a prior video which I need to see? How did she suddenly draw a v/c graph? How is the recording done? What does it do in general? It can probably make sense to someone who is directly from the field but how undergrads are gonna get this? Terrible!
In a cyclic voltammetry you need to sweep the potential and the current is measured due electron transfer and redox reaction,that's how we plot a I/V graph.
Thank you so much for this!! It is so helpful for understanding this topic and so needed!
