Yes, you’re correct! When TiO₂ is doped, it creates intermediate energy levels between the valence band (VB) and conduction band (CB), which can enhance its photocatalytic efficiency. Doping introduces energy states within the bandgap of TiO₂. These intermediate levels lie between the VB and CB, allowing for additional transitions that are typically unavailable in undoped TiO₂. Upon light excitation, electrons from the VB can jump to these intermediate levels, leaving behind holes in the VB. Electrons in the intermediate level can then be excited further into the CB under suitable light conditions. This process effectively increases charge separation, as holes are left in the VB and electrons are transferred to the CB, reducing the recombination rate and enhancing the overall photocatalytic activity. This mechanism is central to improving light absorption and efficiency in doped TiO₂, especially under visible light.

Sure I will explain soon

Thank you mam 😊

We have i x i= -1

Then value of Keva = k1 under root( sin^2 theta t -1) , is it madam?

cos(theta)=sqrt(1-sin^2(theta)) we have cos(theta)=(sqrt(-sin^2(theta)+1), replace -1 with i^2, outside the square root it becomes i cos(theta)=(isqrt(sin^2(theta)-1)

Hi, 1. In B.Sc What is your major subject? 2. For Space related job, Maths also very important subject. 3. I will send some links to you soon , You can understand what are the requirements

For Space related jobs essential things are, Maths+ Physics+ Coding Knowledge So you have to be an expert in one of these subjects. So Make some interest in learning computer programming /Physics other than Maths. In that way you can manage. Passion is more important than knowledge www.nasa.gov/offices/stem/centers/marshall/classroom/index.html Try to learn these step by step. First read and understand that will help you lot

Sure

ok

Can you specify the topic? is it like general talk on Research field?
