It is very useful video. I have some questions. 1) When we will dissolve NaOH and Zn acetate in 15ml and 10ml distilled water, Only Stirring is required r heating is required? If heating is required then kindly what should be the temperature. 2) What will be the best time for stirring? When we will add ethanol in prepared solution, What will be temperature that time? I am waiting for your comment. Thanks..
Mam for how long exact duration we should keep the beaker (containing soln) inside hot air oven and at what temp . 🙏 your single rply will be very much helpful in my research.
I never found it on RUclips that What is the difference between Alfa a MnO2 and Betab MnO2 And how to easily identify and prepare it . Can you tell me or share me related video .
@@NANOTECHNOLOGY_Nanoscience Thanks for Ur reply can we use sodium carbonate instead of sodium hydroxide,and color of zinc oxide nano we get is it white in colour. If u can share Ur mail id as I want to more about zinc oxide.
The temperature of stirring is between 50-60 C. In the final step, a burette is filled with 100 ml of ethanol and tiltrate dropwise to the solution containing both sodium hydroxide solution and zinc acetate. The higher the time of titration, the smaller nanoparticles. I recommend more than 3 hours for titration.
Thank you so much madam, it's interesting and motivating for beginners like me. Can you kindly do some videos on inorganic perovskite oxide synthesis........
Hi, it is very good info. Can I replace zinc acetate dihydrate with Zinc Chloride and sodium hydroxide with sodium carbonate. Then, evaporation in an oven is how long and what is the temperature range???
Thanks for this video. I have a question. Should I add the whole NaOH or just until reach pH=12? I added the NaOH and the solution become clear! Also, it is necessary temperature during this process? and how much ethanol should I added?
Hello, is the NaoH added drop wise or all at a time?, also is the ethanol (100ml) added drop wise and for how long should the stirring last? Can i use methanol instead of ethanol, Thank you
Hello. I am trying to make transparent SiO2 hydrophobic thin film coating solution for application to various surfaces by wipe/spray method. Can anybody advise on how I start on this project. I have limited lab equipment.
can anyone help me by telling me the materials/chemicals required to form nano-tungsten oxide dihydride using simple anodizing process? I'd be grateful. Thanks.

Does burette contain ethanol or contain ethanol and NaOH for titration?
very useful, thanks
could please give a method to elaborate cu doped Zno nanoparticles
Hi, I've sent you an email.
@@NANOTECHNOLOGY_Nanoscience can I too know how to. Prepare Cu - ZnO nanoparticles?
What should be the ph value if Hydrolised solution?
@@monicareddy8261 Hi dear, please send me an email, my contact information is available on the "about" part of the channel.
I have a question. Is the process only drying without heating?Thanks
Thanks a lot..If I want to dope Mg (Source MgCl2) with atomic ratio Mg: Zn (2%) then what amount of MgCl2 will be taken ?
Nice Explanation madam super how prepare nanoparticles by using fruit and vegetables waste please help me madam
good
I never found it on RUclips that
What is the difference between Alfa a MnO2 and Betab MnO2
And how to easily identify and prepare it .
Can you tell me or share me related video .
please upload nanoprecipitation method for the preparation of nanoparticles of any drugs.
WONDERFULL
Thank you
Why did I synthesize the nano-zinc oxide, stacked appearance yellow, how to synthesize the relatively white nano-zinc oxide
Thanks a lot
What will purity of zinc oxide in zinc oxide nano particles which we get?
Hi, about 90 percent.
@@NANOTECHNOLOGY_Nanoscience
Thanks for Ur reply can we use sodium carbonate instead of sodium hydroxide,and color of zinc oxide nano we get is it white in colour.
If u can share Ur mail id as I want to more about zinc oxide.
we have to use ethanol ?and also active zinc oxide and nano zinc oxide are same..?
@@fayazsalema2186 In this method, yeah it's necessary. I haven't heard about active ZnO.
Ma'am during stirring what should be the temperature. And how long time it will take to form White prepitate??
The temperature of stirring is between 50-60 C.
In the final step, a burette is filled with 100 ml of ethanol and tiltrate dropwise to the solution containing both sodium hydroxide solution and zinc acetate. The higher the time of titration, the smaller nanoparticles. I recommend more than 3 hours for titration.

Thank you so much ma'am.
Thank u for the video, what is the use of ethanol? Is it for critical drying?
Hi, yes, it is.
Nice but short
Thanks for your comment.
Thank you so much madam, it's interesting and motivating for beginners like me. Can you kindly do some videos on inorganic perovskite oxide synthesis........
Sure, we will.
@@NANOTECHNOLOGY_Nanoscience 😊😊😊
Hi. What concentration did you make for the compound?
I may wrong, but i think its better to centrifuge the ZnO before dried it ?
You can do that too. There are different methods for the synthesis of nanoparticles.
What kind of morphology do you have with this method?
When ethanol will add drop wise through burette what will be the temperature?
The temprature will be between 50-60 C.

Thanks for this video. I have a question. Should I add the whole NaOH or just until reach pH=12? I added the NaOH and the solution become clear! Also, it is necessary temperature during this process? and how much ethanol should I added?
Thanks for your comment. You just need to adjust the pH between 9 and 11 and you'd better heat the solution while it's stirring.
@@NANOTECHNOLOGY_Nanoscience around what temperature do you heat it to.
@@nancySIX About 50-60 C is okay.
Hello mam, How much NaOH do we wan to add for this preparation?
Can we do it from zinc nitrate and sodium hydroxide? How much is the solution and temperature maintain?
Yes, 50-60 degree centigrade.
Thanks for this menthod ....but i read in google he disolve in propanol not water..i dont know why,can you explain why??
Hi dear, I think for this case the solvent is not important. We used water, but alcohol can be used too.
hello. i have two qeustion.
1. how many time does it take in oven
2. after I dry liquid in oven for 3hour , this powder can be answered ZnO powder?
Hello,
1. about 24 hours is okay
2. yeah, the white precipitate is ZnO nanopowder, if you have done the procedure correctly.
Hello, is the NaoH added drop wise or all at a time?, also is the ethanol (100ml) added drop wise and for how long should the stirring last?
Can i use methanol instead of ethanol, Thank you
Hi, add NaOH dropwise to adjust the pH 9-11. Stirring for 2 hours is okay. Yes, you can use methanol as a solvent.
@@NANOTECHNOLOGY_Nanoscience Thank you very much
@@abdullahikilacousman1749 yrwlcm
Mam can u please give the reference of this method..i need it urgently
No ethanol???
Thanks for this useful video but i need to know how long the reaction need? please tell me time periods for reaction and evaporation.
Hydrolysis reaction took about 2 hours and in order to evaporate the solvents the hydrolyzed solution is heated for about 24 hours.
@@NANOTECHNOLOGY_Nanoscience thank you so much ❤️
@@NANOTECHNOLOGY_Nanoscience i have a question? Heated in what? For what temperature? Thank u
@@jaiho4058 Use oven and an ordinary temperature to vaporize the solvents.
