TL;DR: The findings suggest that the removal of CMT, PRP, and CBZ during photocatalytic oxidation using SI TiO2 NFs is affected by the presence of DOM and/or pH, which should be importantly considered for practical applications.

TL;DR: Monitoring of microcystin-LR and residual Mn2+ levels with adding KMnO4 and powdered activated carbon before and during coagulation revealed that 60 min of permanganate pre-oxidation followed by coagulant addition with PAC was the most effective approach for reducing both levels below limits stated by WHO guidelines.

TL;DR: In this article , non-charge-storage-based nonvolatile memory characteristics associated with oxygen ion exchange are demonstrated in a thin-film transistor (TFT) composed of an indium-zinc oxide (IZO) channel and an oxygen-deficient HfO2-x gate oxide.

TL;DR: The apparatus for water treatment using in-situ activation of a manganese dioxide catalyst includes: a reaction bath configured to give a space where aqueous organic contaminants are removed by means of reaction with permanganate (MnO 4 − ) generated by electrochemical oxidation of manganous oxide (mnO 2 ) as discussed by the authors.

TL;DR: In this article , the authors investigated non-volatile charge-trap memory characteristics in the thin-film transistors with an indium-gallium-zinc oxide channel and an oxygen-deficient hafnium oxide (HfO2−x) chargetrap layer deposited by atomic layer deposition.
