Efficient adsorption of phosphorus by macroscopic MOF/chitosan composites and preliminary investigation of subsequent phosphorus recovery through electrochemically-driven struvite precipitation.

The proper management of phosphorus (P) from wastewater is crucial for sustainable development consideration. Herein, we developed a strategy which combines adsorption via tailored adsorbents and electrochemically-driven struvite precipitation (ESP) for P recovery. Novel polydopamine-modified Ce-MOF/chitosan composite beads (PDA@Ce-MOF-CS) were prepared by a facile in situ growth of Ce-MOF crystals incorporated natural polymers and PDA coating.

Effects of sludge retention time (SRT) on nitrogen and phosphorus removal and the microbial community in an ultrashort-SRT activated sludge system.

The ultrashort-sludge retention time activate sludge (USAS) process is considered promising for the recovery of energy and resource from wastewater. In this study, we developed five USAS systems (with sludge retention time (SRT) of 0.5, 1, 2, 3, and 4 d), and investigated the nitrogen and phosphorus removal, as well as the microbial community, in the USAS systems.

Community succession during the preventive control of cyanobacterial bloom by hydrogen peroxide in an aquatic microcosm.

Hydrogen peroxide (HO) is an environmentally friendly algaecide with good prospects for cyanobacterial bloom control. In this study, 0.2-1.

Involvement of the Nrf2 pathway in the regulation of pterostilbene-induced apoptosis in HeLa cells via ER stress.

Among the various cancer cell lines, HeLa cells were found to be sensitive to pterostilbene (Pte), a compound that is enriched in small fruits such as grapes and berries. However, the mechanism involved in the cytotoxicity of Pte has not been fully characterized. Using biochemical and free radical biological experiments in vitro, we identified the pro-apoptotic profiles of Pte and evaluated the level of redox stress-triggered ER stress during HeLa cell apoptosis.
