Role of Naoh in CQD

What is the name of the synthesis.?

I just started my PhD research on silicon quantum dots. This a great video ror me even with it being carbon

Can we also make this from plastic waste?

Appreciating

Excellent demo, but three questions 1) What was the concentration of ethanol used in initial step? 2) What kind of filter was used in chromatography? 3) What was the pressure of N2 pump?

Name of this method

I tried this method . But I had a problem to dissolve PVP

Currently doing my PhD on carbon dots. Lovely video guys, well done.

Try ZnInS2 quantum dots as well they are very bright and sparkly.❤

Try swapping some cadmium out for zinc and season with a bit of indium. It will ceate delocalized electrons that could allow these to be used for a lot of interesting applications.❤

Why didn’t you set a constant current in the power supply instead of manually adjusting the voltage?

Pet ether/diethyl ether is very good for chromatography of extremely nonpolar molecules. ❤

Is there any easier method to purify quantum dots in order not to use dangerous chemicals?

Very irritating sound

for N2S solution using 156 mg N2S, the calculation is 80 mM not 40 mM ? 40 mM or 80 mM using in this experiment?

Can i use this material as light emitter in my oled?

Merci

Muito bom

Muy bueno

Hello dear researcher I want to make nanoparticle which is able to seperate peptide(bioseperation). Can I use your method as a base of magnetic nanoparticles and cover them by sodium silicate and APTES or not? I should make IONPs and after that cover the by mentioned materials. Howevwe, when I added nanoparticles to sodium silicate solution, something like a gel formed? What is the problem? Can you help me? Is there any replacement?

I have a question, may I please have your email address?

what is the molar concentration of the prepared CdTe QDs ?

I'm sorry to say that there are still problems in the administration and experimental operation of drugs

What the heck is the big deal about measuring NaOH and ethanol that there should be loud music in the background. Why not simply provide running commentary instead.

and how to control size of these quantum dots?

Nice, but couldn’t help noticing the improper use of a sureseal here. Be sure to pressure equalize with an inert gas!

There's a mistake at 3:19. Resulting solution should be 250 ml and not 25 ml. Also, can you explain the reason for adding HCl when you want to precipitate later on with ammonium hydroxyde? Thank you.

What is this music piece? Strauß?

Great work!!

Simple and easy way to undersatand thanks

This method didn’t work with me.

Could you please explain step3? What is the final volume of the solution? I think you mean 250 ml, is it? What is the final concentration? What is the NH3 % in the Ammonium solution?

Thank you

Chemical coprecipitation method is best sir

Thank you so much for this method I have a question, if I want Fe3O4 with PEG What method used Please 🙏

How can I contact you? Do you have an email?

will I infringe any patents if I repeat this process?

Who recommended 😂😘✨🔥

anyone prepared ZNO Nanoparticles by sol gel method ?

Hey, is there any preference to the top-down method rather than bottom-up? it appears that this method is far more complex than bottom-up using a precursor

where can i find supplementary information for this work?

Sounds interesting

Preparation and performance of metal-doped carbon quantum dots

Good job. What is the role of ethers

What power source u are using for dissolving graphite in ethanol solution??

Thanks for this video. It was really, really useful.

Particles size is increasing with increasing current or by decreasing it?Thanks!

Entre mas alta la corriente es mas pequeña la partícula?
