Please show us how to make ceramic car coatings thanks.
Probably the most useful video sillica nanoparticle synthesis in the entire internet, great work!
This class was amazing! Its a kind of thing that you just learn by trying and experience it. The tips was great!
So nice, thanks
Dear Prof, can I have your email ID?. I would like to apply for postdoc..

why the surgical mask????
Nice video! I am studying Regenerative Medicine and taking a course called Nanomedicine. When writing my paper it was nice to visualize what all the articles were talking about. Thanks!
"Welcome to Nanoengineering" XD!! Very informative in a funny way. Thank you very much Jesse!!
Hi Jesse. First of all, I appreciate your work and explanations. I’m trying to synthesize hollow silica nanoparticles based on the soft template (PS). I’ve noticed that the silica is stuck to the plastic Eppendorf. So I thought I that I have to use a glass flask. But, Why is it working with you to use the plastic tubes? Thank you very much.
I need to know synthesis procedures of silica nanoparticles from rice husk
Hi. Really nice explanation. Can you please make a video on FTIR ?
What a nice lecture!!! Thanks for sharing.
An informative explanation of DLS. Thank you Jesse.
very nicely explained sir, I appreciate you
Could you please tell me that how can i get this procedure
Hi, please where I can find the procedure that you've used during the experiment?
Hye Mr. Jesse. Are there any ways to contact you? I found your profile on linkd in but I'm unable to send you a message. Do you have other social media?
Just wanted to thank you for your contents. I am deeply grateful😇
Informative and digestible, thanks!
Overall your lecture is a "two thumb-up lecture" ! 👏👏👏👍👍 I have to stop for tonight at half of your lecture (0:43) but I'll be coming back to it tomorrow.
X axis (time): I think 0.1 s is largely enough, don't you ?
DLS: I'd rather say instead, yes, look at the magnitude : the larger the particle the larger intensity variations as intensity is proportional to the MW * massic concentration (mg/mL), which means a small amount in mass of a very large particle can have a significant impact on the collected intensity and hence.the correlation function.
Interesting lecture. Congrats ! 👍👍
No, interacting particles are still submitted to the same forces but the object under motion is no longer the same.
great. thanks
