Summary: The highly crystalline hollow TiO2 microspheres were nanostructured to contain recognition sites for bilirubin and doped with Ag to achieve photocatalytic response to visible light. Ag-doping showed positive catalytic effect, especially for molecularly imprinted hollow microspheres doped during synthesis. The kinetic constants and selective photocatalysis were significantly enhanced by Ag-doping, leading to a higher rate of bilirubin degradation.

Summary: Biotoxins with high toxicity can be transformed into biochemical weapons, posing a significant threat to international public security. A molecular imprinting platform (HMON@MIP) was developed using hollow-structured microporous organic networks (HMONs) as imprinting carriers, enhancing the adsorption performance in terms of specificity, imprinting cavity density, and adsorption capacity. The platform shows promising generalizability by producing various MIP adsorbents through changing the biotoxin template, such as aflatoxin and sterigmatocystin. The developed imprinting platforms have great potential for precise food safety inspection.

Summary: In this paper, we report the synthesis and characterization of light-driven mesoporous silica-IP nanomaterials that efficiently remove Pb2+ ions from wastewater. The material's fibrous structure provides a large specific surface area and adsorption sites, achieving a theoretical maximum capacity of 69.78 mg/g. The studies on actual wastewater show a significant reduction in Pb2+ ion concentration to 1.76 mg/L, demonstrating the material's excellent effectiveness in treating contaminated water sources. The photosensitive material on the surface enables rapid separation of Pb2+ ions from wastewater.

Summary: This study investigated the stabilization mechanism of Pickering emulsion using mesoporous hollow silica microspheres (MHSMs) as stabilizers. The results showed that smaller particle size and shell thickness of MHSMs can improve the stability of Pickering emulsion, and MHSMs with intermediate hydrophobicity and suitable oil/water ratio are favorable for stability. Increasing the concentration of MHSMs within a certain range can enhance the stability of Pickering emulsion, with the optimal concentration being 1.25 mg/mL. This research opens up possibilities for the fabrication of functional materials through Pickering emulsions.

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.

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.
