TL;DR: It is indicated that soil properties were more influential in determining soil bacterial composition and diversity than heavy metals even at the e-waste site which was seriously contaminated by heavy metals.

TL;DR: Heterogeneous photo-Fenton systems are most promising for practical applications because of the inherent higher catalyst stability and modern methods of quantum chemistry are expected to play a continuously increasing role in development of such catalysts.

TL;DR: Thermogravimetric analysis showed that the presence of PBFA can accelerate EP decomposition at comparatively low temperatures and lead to the formation of a stable char layer, which protects the matrix from fire, therefore improving the amount of char residue at 800 °C.
