Deep learning-based PM2.5 prediction considering the spatiotemporal correlations: A case study of Beijing, China.
TL;DR: The proposed spatiotemporal convolutional neural network and long short-term memory model was proposed and used to predict the next day's daily average PM2.5 concentration in Beijing City and was proved to have a better stability and prediction performance compared to multi-layer perceptron (MLP) and LSTM models.

TL;DR: In this paper , it was shown that 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonate) (ABTS) could act as both activator and electron shuttle for PDS activation to enhance diclofenac (DCF) degradation over a pH range of 2.0-11.0.

Oxidation and coagulation/adsorption dual effects of ferrate (VI) pretreatment on organics removal and membrane fouling alleviation in UF process during secondary effluent treatment.
TL;DR: In this article , the authors investigated the role of oxidation and coagulation/adsorption effects of Fe (VI) during membrane fouling mitigation in water and wastewater treatment.

Enhanced high-salinity brines treatment using polyamide nanofiltration membrane with tunable interlayered MXene channel.
TL;DR: In this article , a scalable approach for constructing TFNi membranes was implemented using stacked MXene nanosheets as interlayer, wherein the Fe3O4 nanoparticles worked as the sacrificial template to regulate the interlayer spacing of the 2D channels.

Insight into the performance of UV/chlorine/TiO2 on carbamazepine degradation: The crucial role of chlorine oxide radical (ClO•).
TL;DR: In this paper , the second-order reaction rate constant between ClO• and carbamazepine was fitted to be (1.21 ± 0.08) × 107 M-1 s-1 by the kinetic model, which avoided the influence of carbonate radical (CO3•-), whose contribution couldn't be excluded during kClO•,carbamazepINE determination in commonly used competitive kinetic methods with bicarbonate.
