Summary: Piezoelectric polarization is a promising strategy for enhancing charge carrier separation and transfer in photocatalysts by modulating energy band structure. In this study, a binary piezoelectric integrated piezo-photocatalytic heterojunction o-KNbO3/MoS2 was fabricated, which exhibited higher piezo-photocatalytic degradation rates compared to individual photocatalysis or piezocatalysis. The results demonstrate the potential of integrated piezo-photocatalysts in achieving efficient pollutant degradation and enhancing electrochemical performance.

Summary: Cr(VI) has minimal effects on aniline degradation efficiency, but significantly inhibits nitrogen removal function. When the concentration is below 5 mg/L, nitrification performance recovers spontaneously, while denitrification performance is severely impaired. With increasing Cr(VI) concentration, the secretion of EPS is strongly inhibited and bacterial abundances are altered.

Summary: The development of sustainable, low-cost and responsive technology for heavy metals detection in wastewater is crucial. In this study, a novel photo-microbial fuel cell (PMFC) sensor was developed by combining CuO/ZnO photocathode with microbial anode. The PMFC sensor showed a wider detection range and improved sensitivity, attributed to the intimate P-N heterojunctions formed in CuO/ZnO.

Summary: The B2O3-CaF2-Bi2O3 glass-ceramics with precipitating CaF2 crystal were prepared and their crystallization behavior and microstructure were studied. Up-conversion glass-ceramics with Yb3+ and Tm3+ doping were also prepared and analyzed for their crystallization, microstructure, and up-conversion luminescence performance. Li+ doped up-conversion glass-ceramics were explored to further improve the up-conversion luminescence performance. The addition of up-conversion glass-ceramics increased the photocatalytic degradation efficiency of ZnIn2S4-Ag-LaFeO3 photocatalyst for dye contaminated methylene blue.

Summary: In this study, a g-C3N4/PDI-g-C3N4 homojunction was fabricated for piezo-photocatalytic atrazine removal, demonstrating superior performance compared to individual photocatalysis or piezocatalysis. The introduction of PDI facilitated electron migration and enhanced piezoelectricity, with the homojunction promoting photoelectron transfer. The porous structure of the g-C3N4/PDI-g-C3N4 was found to be essential for the enhanced piezoelectricity, leading to a high atrazine degradation rate and H2O2 production during the piezo-photocatalytic process.

Summary: In this study, breeding wastewater was efficiently treated using an electroactive microbial community screened from the native microorganisms of the wastewater in microbial fuel cells. The results showed good power generation and high pollutants removal efficiency. The morphology characterization demonstrated the formation of a thick biofilm by the screened electroactive microbial community. Microbial community analysis revealed an increase in microorganisms associated with electricity generation and pollutant degradation, while pathogenic microorganisms were greatly decreased. These findings suggest that the MFC constructed using the screened electroactive microbial community can be a sustainable method for breeding wastewater treatment.

Summary: After connecting two double-anode microbial fuel cells (MFCs) in series, one MFC experienced decreased electricity generation, while the other was minimally affected. The removal efficiencies varied between the two MFC reactors, with the MFC that generated less power showing higher removal efficiencies. Changes in microbial communities were observed, with an increase in communities related to the degradation of refractory organic compounds and a decrease in communities related to electricity generation in the MFC with reduced electricity generation.

Summary: Bacterial outer-membrane multi-heme cytochromes (OMCs) can modify heme coupling through mechanical interactions among OMCs by controlling their concentrations. The concentration of OMCs significantly impacts their circular dichroism (CD) spectra and redox property, resulting in a 4-fold change in microbial current production. Overexpression of OMCs increases the conductive current across the biofilm, indicating enhanced inter-protein electron hopping via collision on the cell surface.
