Dear NANOTECHNOLOGY team and presenter, I really appreciate your nice presentation or lecture about the synthesis of TiO2 nanoparticles. If you are really interested in answering my question, let me go to the question. 1) The output from the preparation or synthesis is colodial solution or powder; which one is the final result? 2) Is there any difference between the three phases (Anatase, Rutile, and Brookite) of the TiO2 preparation method? 3) WHICH ONE IS MORE PREFERABLE AS THE USED ELECTRON TRANSPORT LAYER FOR ORGANIC SOLAR CELLS AMONG Anatase, Rutile, and Brookite? Thank you!
We hve to drop mixture of HNo3+ H2O in such a way tht this drop wise take 4 hours ? After tht we hve to again stir it for 2 hours? Please suggest me regarding this confusion of mine. As after adding hno3 solution nd after tht when i stir it for 2 hours it is becoming totally transparent.
Adding solution 2 to solution 1 slowly in the sol-gel method allows for better control over the reaction kinetics, resulting in the formation of a more homogeneous and well-defined gel structure. This gradual addition helps prevent the rapid generation of excess heat and the formation of unevenly distributed particles, leading to a higher quality final product.
Thnku for the reply sir. But i wnt to ask tht the tym period of adding hydrolysis solution i.e, solution 2 in solution 1 should be done in 4 hours? After adding this we need to stirr it for 2 hours more? Bcz I had read your research paper of this, it was written in the protocol tht for hydrolysis reaction the aqueous solution was injected dropwise to the mixture of TTIP nd ethanol The mixture was stirred for about 2 hours at 60°C. But after adding the mixture 2 in mixture 1 when I stirrer it for 2 hours at 60°C my solution is becoming transparent nd no viscosity is there Please suggest me about this sir as I m not able to make my nanoparticles
@@shireenkhan9590 That 2 hours is usually optional. For example, you want to add another material to modify the surface of the nanoparticles, then you need to wait another 2 hours.
Hi, thank you for your comment. Yes, you can cite the following articles: 1. www.sciencedirect.com/science/article/abs/pii/S025789721730720X 2. iopscience.iop.org/article/10.1088/2053-1591/aad2b8/meta
@@NANOTECHNOLOGY_Nanoscience Sir, what might be the possibility when ethanol is substituted with propanol. Will there be a larger difference in its tio2 properties or none? Thanks and anticipating your reply
hello thanks for the great video that you created, I have a question, I want to know how much Tio2 is left for you at the end? for instance I need 10gr tio2 at the end, how much ttip and other stuff do i need? thanks
سلام وقت به خیر میتونید کمکم کنید وقتی میگه سنتز یک ماده به روش سل ژل با نسبتهای مولی مثلا 0.03Al2O3:SiO2:80H2O:0.45TPAOH انجام شده و بخوابیم این سنتز انجام بدیم فقط باید این اعداد را از مولار به گرم تبدیل کنیم ؟؟؟ و آیا به چه حجمی رسیده میشه هم مهم هست؟ میشه این سنتز به روش سل ژل به من توضیح بدید خیلی واجبه ممنون و روش بدست آوردن مقدار موادش
@@NANOTECHNOLOGY_Nanoscience فقط یه چیزی من الان مثلا منبع SiO2 را TEOS گرفتم پس باید جرم‌مولی اونو استفاده کنم و تبدیلش به گرم کنم دیگه ؟ واقعا ممنون جواب دادید میخواستم تلگرام یا ایمیل مزاحمتون بشم هرکاری کردم نشد

Please tell me what is difference between in tiO2 and ttip ?
The TTIP undergoes hydrolysis to become TiO2 in the gel

Ok, means by the dropwise process should be done in 4 hour nd after tht, we need to stop the reaction nd placed it in oven
Hi, how can I fix a thin layer of nanoparticles to glass or steel?
Which nanoparticle?
TiO2@@NANOTECHNOLOGY_Nanoscience
hi did you add any coating to them after obtaining the nanoparticles ?
Good morning I used this method and it worked well. Do you have any publication with it so I can site you?

3-4 gr
Hello, thanks for your great video. I want to ask. What is the phase Percentation % of that TiO2 (anatase , Rutile ,Brookite)?
I think you can conclude using the color of Nanoparticle solution.

وقتی میگه سنتز یک ماده به روش سل ژل با نسبتهای مولی مثلا
0.03Al2O3:SiO2:80H2O:0.45TPAOH
انجام شده
و بخوابیم این سنتز انجام بدیم
فقط باید این اعداد را از مولار به گرم تبدیل کنیم ؟؟؟
و آیا به چه حجمی رسیده میشه هم مهم هست؟
میشه این سنتز به روش سل ژل به من توضیح بدید خیلی واجبه ممنون و روش بدست آوردن مقدار موادش
بله نسبت مولی هستش، یکی از موادو به عنوان مبنا درنظر بگیری بقیه باتوجه به نسبت محاسبه میشه و میتونید با جرم مولیشون گرمشون هم حساب کنید
