TL;DR: In this paper, visible light (VL) was adopted for permanganate (PM) activation without additional catalyst, where sulfamethazine (SMT) was selected as the probe compound and showed that the VL/PM system can effectively degrade SMT through pseudo-first-order reaction kinetics.

TL;DR: The present results demonstrate the potential of applying light-to-heat conversion in Fenton-like processes in pollution control, which opens new avenues towards utilization of inexhaustible solar energy and novel approaches for environmental remediation.

TL;DR: The correlation between core microbial genera was very low from network, indicating a complex and non-specific mutualistic network between bacterial functional groups under each nutrient condition, and a stable coexistence state was possibly formed through utilizing each the secondary or waste metabolites in the mixotrophic conditions.

TL;DR: The acceleration mechanism of Fe3+/Fe2+ cycle by BRP is clarified, the control strategy of by-prodoct formation is proposed and the contaminant degradation performance of BRP was significantly elevated.

TL;DR: The viral peaks with regular temporal intervals indicated that SARS-CoV-2 may have a cluster spread, probably reflecting that the majority of infected persons only spread the disease during a few days.
