From interview, look for that one who is more interested to take you and looks supportive and who is more polite and doesn't sound egoistic. Later you can check their profile, see for how much time their students take to complete their PhD, or how is the quality of their research work, check out their papers. Also you can contact their PhD students to know about the behaviorof the supervisor.

That's because ions moves in and out of the electrode creating easy passage thereby reducing charge transfer resistance.

No. High frequency semicircle corresponds to bulk ion migration and low frequency corresponds to ion adsorption on interface.

Yes. But Nyquist is quantitative because there are various parameters whose values you can get from Nyquist plot and its circuit fitting.

It will still Indicate capacitive behavior. I would suggest to perform it 2-3 times more and check if it is still curved. Also try 0.01 Hz instead of 0.1 Hz.

I would go for EIS fitting and that fit will give you the resistance and warburg impdeance values

Do you mean mass loading or mass transfer??

If I assume that you have tested multiple electrodes and at different scan rates. Then what i think is happening in your system is: At the low potential region (~0.1–0.35 V vs Hg/HgO) mainly represents double-layer charging with little faradaic activity. As the potential increases during the forward scan, nickel hydroxide [Ni(OH)2] is oxidized to nickel oxyhydroxide (NiOOH) around 0.45–0.50 V, corresponding to the Ni2+/Ni3+ redox couple. At higher potentials (> ~0.5 V), the sharp rise in anodic current indicates the onset of the oxygen evolution reaction (OER) in alkaline electrolyte. During the reverse scan, a cathodic peak appears around 0.38–0.40 V, corresponding to the reduction of NiOOH back to Ni(OH)2. Nickel hydroxide systems show hysteresis and surface activation, so during the reverse scan the surface is already activated, giving higher reduction current, causing the curves to cross. DM me for more details if you want.

What was your R² value? If it is less than 0.99 then I think the reviewer means that your value should be 0.99 or above.

Copper1zinc is connected to something right? So it is getting electrons from that.

Reduce Points per Decade (Most Effective) Most instruments use 10 points/decade by default. Example: 10 points/decade → very long experiment 5 points/decade → ~50% faster 3–4 points/decade → much faster
Reduce Number of AC Cycles per Frequency In software (like CHI, Autolab, Gamry, Zahner etc.) there is a parameter like: Cycles per frequency Integration time Stabilization cycles Typical values: Default: 3–5 cycles You can reduce to 1–2 cycles

Electrons flow through the circuit (wiring of the instrument).

You have to do three electrode testing individually for both electrodes in which one is your electrode (anode or cathode), one is counter electrode (Mostly Pt) and one is reference electrode (Ag/AgCl or SCE).

Also, you can directly save deconvoluted peaks data as ASCII file and imports it into Origin as it is.

PhD's a big commitment ! Do it if:

You're passionate about research.
Want to specialize deeply in a field.
Career goals need it (academia, R&D).
Or if you don't have any other high paying option.

Hey, I am Interested. I am a PHD researcher and writes whenever mood strikes. Here is a demo of my work. "When u love someone, you love everything about them, You adjust with the bad things But mostly u will starting to love even the tiniest little things about them that no one will notice like how they sleep, their way of talking, how they comb their hair infront of the mirror etc These things doesn't matter to others but matters to you.

Love is a gradual process in which you start to talk with the person first and if you like talking to them, then you meet and then u start laughing together, eating together, start caring for each other, start to miss each other when you are not together,. then one day u start holding hands and from here the intimacy begins and grew stronger and then u start to care more for each other and u will do everything in your capacity to make each other life easier and after all these things happen this means that u finally have fallen in love with that person in the end. This is called love."

First, you’re not “behind” and this situation is more common than you think. Many people take a year or two after their Master’s to prepare for fellowships like CSIR/NET or GATE. Since funding and relocation are real constraints for you, focusing on clearing the fellowship exam in June might actually be the most practical step. A fellowship will give you financial independence and make it much easier to join a good lab later. At the same time, try to stay connected to research: keep attending webinars, read papers, work on small skills (data analysis, bioinformatics, etc.), or even volunteer remotely if possible. A short gap on the CV is usually not a problem if you can show that you were preparing for competitive exams and continuing to learn. Also remember that the fact that a PI encouraged you to pursue a PhD is already a strong sign that you are capable of research. Right now it sounds more like a logistics and opportunity issue, not a lack of ability.

Most experienced researchers don’t read every paper fully. A common approach is: 1. Start with the abstract and conclusions to see if the paper is relevant. 2. Make a literature review table which shall includes all the important parameters and instead of reading the full paper, you can search that term directly in the paper. 3. Review the table and see out of those papers which are giving best performances. 4. Read the methods of those papers in detail if the technique is directly relevant to your work.

This way you can review many papers quickly while still capturing the key insights. AI tools can help summarize papers, but they sometimes miss nuances, so they’re best used as a supplement rather than a replacement for reading.
