Thank you for the informative video session. Can you make a video regarding capacitive and diffusion contribution, by the Dunn method and also the transatti method?
I am facing the same problem means low value of specific capacitance. But the area you calculated should be 0.00034AV. My values of area are also in 10^_4 and 10^_5. So specific capacitance is very low. What I have to do?
I think you have calculated the change in the specific capacitance , because you have measured the area in between two cycles of cyclic voltammogram. Please clarify my question.
also i'm working on calculating electrochemical active surface area. its = Cdl/Cs i believe you are aware that the slope of I vs scan rate gives Cdl while for Cs i can follow your tutorial but does Cs in the formula means finding specific capacitance of different scan rates and averaging it. or just one Cs is sufficient? Kindly reply @nanoencryption i also welcome other viewers/aspirants watching this video to kindly join the forum for discussion in clearing my doubt thanks in advance
Hello, I need to calculate areal capacitance by changing the scan rate in CV using 0.1M KCl or 0.1M NaCl. Can you help me that how can I do this, how much scan rate should I change each time?
In the calculation of area it is wrong since there is two curves which will affect the area under the CV curve ..it will give extra area which will be reflected in the capacitance
Yes, Sir I have tried but I am not able to separate them that's why I have taken the whole graph. But this video is only for knowledge purpose that how can we do and calculate the specific capacitance.
@@NanoencryptionSKP you can separate it by using voltamaster app, there you can see your curve for each cycle. So you can select the cycle you want and then save its data.
For studies of Electrochemical characteristic of Electrode material three electrode is best, while for supercapacitor and battery like application where EMF is generated in between anode and cathode , two electrode system is more suitable.
Hi there, may I know what's the difference between finding the area under the curve through 'Integrate' and 'Polygon Area' ? Which one should we actually use to calculate specific capacitance? Thanks
Hi Sir, what is mass? is it the amount that we coat over the glassy carbon electrode? i was wondering coz mine is 0.01mg over the GCE is it what u meant as 3mg in ur video?? kindly reply
Sir your area calculation is wrong. Cyclic graph polygon area is 3.4472E-4 which is equal to 0.00034472. But you put area value in excel calculation is lesser that is 0.0034472. Hence your calculated Cp value is 14.36333. Since it is wrong. If you will have been put correct area value (0.00034472) and you will get the correct value of specific capacitance (Cp) that is 1.436333. Sir please give your correct valuable comments about Cp calculations.
I really love that you chose Bethoven as backround music.

Thanks for your informative video. Kindly make a video on how to analyze gas sensing data.

Demonstrate that the units of Cp are F/g if you use (AV)/(m (mV/s)V)

This is amusing
also i'm working on calculating electrochemical active surface area. its = Cdl/Cs
i believe you are aware that the slope of I vs scan rate gives Cdl
while for Cs i can follow your tutorial but does Cs in the formula means finding specific capacitance of different scan rates and averaging it. or just one Cs is sufficient?

Why there is no sound, this vedio looks interesting but at the same time boring as no explanation is available.
Hi, I have 10 cycles and I am facing problems in finding the area. Can someone help me???

What is the major difference between two and three ekectrode system and which electrode system is best for supercapacitor application?

While using 3 electrode cell take integrate absolute area divided by 2

Sir if our curve is open then how could we calculate the area or if only we have to consider the charging or discharging area then how we calculate?
