Summary: The synthesized g-C3N4 and Ag-TiO2 photocatalysts exhibit high efficiency in degrading dyes under both UV and visible light irradiation, with Ag-TiO2 being more responsive to UV light and g-C3N4 effectively promoting photocatalytic degradation under visible light. The synergistic effect between g-C3N4 and Ag-TiO2 leads to efficient degradation of cationic and anionic dyes under both UV and visible light, with the ability of Ag0/Ag+ to switch oxidation states advantageous for suppressing recombination.

Summary: The study synthesized a core-shell structured MOF@TiO2 as an efficient photocatalyst for toluene degradation, exhibiting a higher degradation rate compared to pristine NH2-UiO-66. The NH2-UiO-66@TiO2 catalyst showed stable performance in repeated reuse experiments and a reactivation after washing with ethanol, with a photocatalytic mechanism involving efficient transfer of photogenerated holes and electrons to produce hydroxyl radicals and oxygen radicals for toluene oxidation. The construction of NH2-UiO-66@TiO2 is considered as an effective approach for the photocatalytic degradation of indoor air pollutants, providing new insights into core-shell structured MOF@photocatalysts design.

Summary: A plasma-assisted catalyst modified with biochar was found to significantly enhance the photoactivity of TiO2 for formaldehyde abatement. The addition of 5% biochar to the catalyst (C/TiO2) achieved the highest removal efficiency by increasing meso/microporous structures, decreasing the bandgap, and diminishing the recombination rate of electron-hole pairs. This new catalyst has promising applications for the degradation of volatile organic compounds.

Summary: The study focused on preparing semiconducting materials like TiO2 and transition metal-doped TiO2 using a sol-gel method and characterizing them through various analyses. Among them, Zn-doped TiO2 showed the best photocatalytic efficiency in decolouring Methylene blue dye under visible light irradiation. Results indicated that Zn-doped TiO2 had a lower band gap, leading to enhanced dye degradation compared to other catalysts. UV-vis spectra and the decolouration percentage of Methylene blue showed the superior photocatalytic activity of Zn-doped TiO2.

Summary: The TiO2/graphene nanocomposite supported on clinoptilolite nanoplate prepared by hydrothermal method showed significantly higher photocatalytic degradation efficiency for nitenpyram insecticide under visible light, mainly due to the advantages of clinoptilolite and graphene, such as microporous structure and enhancement of effective surface area. The hydroxyl radicals were identified as the main active species responsible for the photocatalytic degradation of nitenpyram. This study provides a new insight for fabricating more effective zeolite and graphene-based nanocomposite photocatalysts for environmental remediation.

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.
