Summary: A series of 3D ordered macroporous (3DOM) Bi4O5Br2 photocatalysts with different macropore sizes were fabricated using a PMMA template method. The photocatalytic activity of 3DOM Bi4O5Br2 first increased and then decreased with the rise in macropore size. Specifically, 3DOM Bi4O5Br2-255 exhibited the highest photocatalytic activity among various catalysts tested, showing significantly higher efficiency in phenol degradation compared to bulk Bi4O5Br2, Bi2WO6, and g-C3N4. The improved performance of 3DOM Bi4O5Br2-255 can be attributed to its enhanced phenol adsorption, O2 activation, and charge separation and transfer abilities.

Summary: 3DOM Ce-W-Nb ternary catalysts show excellent NH3-SCR activity, high thermal stability, and durability. The addition of Nb leads to more evenly dispersed active sites and increased specific surface area. The interaction among Ce, W, and Nb species enhances the chemisorbed oxygen, promoting SCR activity, while Nb doping boosts NH3 adsorption and facilitates the generation of active NOx species, accelerating the reaction rate.

Summary: This study demonstrated that the substitution of A-site with potassium ions in double perovskite-type oxides can enhance the surface density of active sites and improve the catalytic performance for soot purification. The 3D ordered macroporous structure of the catalysts significantly promoted the contact efficiency between the catalyst and soot particles, leading to superior purification performance. The proposed mechanism suggests that the increase in surface oxygen density induced by potassium ion doping plays a crucial role in promoting the oxidation of NO to NO2 during the catalytic process.

Summary: Au-Pd bimetallic nanoparticles supported on 3DOM Al2O3 with different Au/Pd ratios were synthesized using the micropores-diffused reduction method. The supported bimetallic catalysts, especially Au-2-Pd-2/3DOM Al2O3, showed higher catalytic activity for soot combustion due to synergistic effects between gold and palladium. The Au/Pd ratio influenced the chemical states and size of the nanoparticles significantly.

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.
