At 19:16, A plot is shown with BN degrading PFOA with time under 254 nm illumination. Just before this, it was stated that BN has a band gap of 6 eV. 254 nm is only ~4.9 eV which wouldn't be enough to do the photocatalysis. I was curious if the light source used was measured to ensure it can excite the band gap of the BN or if the observed reactions are actually from defect sites on the BN. Is there any theoretical precedence for these potential defects? If the latter is true, does that change your approach for degrading PFAS? Perhaps more focus understanding the true underlying mechanism might be more fruitful. Thanks for the nice talk!

I have a question for Dr. Jabbari Cyrous: if I am not mistaken, you have written a book on political and military strategies; under what title is it available in Austria?

Can waste contain ionic salts? I understand these would drop out of the sH2O. If it can handle ionic salts is there any way it could be used efficiently to desalinate water for drinking?

Wow, it kinda worked! Happy reducing the granule regeneration from diethyl alcohol (iirc) to something you don't have to bake off much.

Hello, Really interesting and important work! I like that. I would like to know how much energy you can produce at an efficient day if 1t of mass gets converted. Best regards

If dioxane can penetrate to be stored in clay & slit layers, that implies that dioxane might make its way through clay layers to deeper aquifers, especially if the dioxane sources are not remediated.

One wonders what conditions led to the +130 month halflife bar at ~05:30. That's more what looks like more anaerobic conditions in perhaps a deeper aquifer like we're seeing here at the Gelman dioxane site. Plus here, an unknown quantity of the original dioxane discharge is still on the site and being left to spread because the dioxane is not yet in a "usable aquifer". How much dioxane is "stored" in clay and slit layers on and offsite is also unknown. Thanks for sharing this presentation.
