Summary: Recombination and redox energy declination of photo-induced carriers in their transfer over photocatalysts cause efficiency loss in photodegradation of contaminants. Constructing a Z-scheme transfer mechanism is considered as a promising approach to boost photocatalytic activity. In this study, direct Z-scheme CuInS2/Bi2S3 heterojunctions were successfully fabricated, showing superior photocatalytic performance towards the reduction of Cr(VI). This study provides a feasible strategy to improve the photoreduction performance of CuInS2-based composites for Cr(VI)-containing wastewater treatment.

Summary: The application of positively charged polymers, such as polyethylenimine (PEI), has shown significant potential for the sorption and reduction of hexavalent chromium Cr(VI). The study demonstrates that the photoactive nature of PEI enhances Cr(VI) photoreduction, with the efficiency being dependent on the density of amine groups. When combined with graphene oxide (GO) as a stabilizing scaffold, the performance for Cr(VI) treatment is influenced by the mass loading of PEI, its molecular weight, and the oxidation extent of GO. Furthermore, combining PEI with magnetic nanomaterials allows for low-energy, high-efficiency separation and reuse, showing excellent performance over multiple cycles.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
