Summary: To improve the removal ability of alkaline lignin (AL) towards heavy metals, trimercapto-s-triazine trisodium salt (TMT) was used as a modifying agent to introduce reaction groups. The successful introduction of -SNa, C-N, and C = N groups was confirmed by FT-IR spectra and SEM. The adsorption performance of the modified AL-TMT towards copper (II) was evaluated, and the results showed better adsorption selectivity towards Cu(II) than other heavy metals. This research provides a theoretical basis for the extraction of specific heavy metals from water or wastewater using modified alkaline lignin.

Summary: The rational design of strong affinity adsorbents for heavy metal ions remains a challenge in water treatment. In this study, amorphous molybdenum sulfide composites (EDTA-MoSx (x = 2, 3)) were successfully synthesized and showed superior adsorption capacity for Cu2+ ions, attributed to the covalent bonding of S-2(2)- and -COOH groups with the ions. The work offers a new method to enhance adsorption performance by controlling crystallinity with organic complexes.

Summary: Searching and developing efficient adsorbent materials for arsenic removal is critical in water treatment. Metal-Organic Frameworks (MOFs) have gained attention due to their chemical stability and ability to capture water-soluble arsenic species. This study investigated the arsenic removal ability of a zinc-based MOF and the effects of metal exchange. The results showed that metal exchange can enhance the adsorption ability of the MOF. The study provides new insights into the application of MOFs in arsenic removal technology.

Summary: In this study, a lactone-atorvastatin prodrug with atropisomeric features was successfully synthesized. Conformational and experimental studies were conducted to assess the stability of the chiral axis, and docking calculations were used to evaluate the continuous inhibition of a library of atorvastatins. The best candidate was fully synthesized, yielding a thermally stable atropisomeric lactone-atorvastatin. Chiroptical ECD spectroscopy coupled with TD-DFT calculations were used to determine the absolute configuration of the chiral axis of the atropisomers.

Summary: In this study, Cs2AgBiBr6/M3C2 heterostructures were constructed and characterized using density functional theory (DFT) and experimental studies. The results showed that AgBiBr3/M3C2 heterostructures exhibited superior interfacial properties compared to Cs2BiBr3/M3C2 heterostructures, with smaller interfacial distance, higher binding energy, and better charge transfer ability. Among the AgBiBr3/M3C2 heterostructures, AgBiBr3/Ti3C2 and AgBiBr3/Zr3C2 showed the best binding energy and charge transfer ability. Furthermore, all the constructed heterostructures showed improved light absorption coefficient, broadened visible light absorption range, and reduced effective mass of the charge carriers. The experimental synthesis of Cs2AgBiBr6/Ti3C2 composite materials confirmed the feasibility of the theoretical models. These results provide valuable theoretical guidance for developing high-performance Cs2AgBiBr6/M3C2 heterostructures in optoelectronic perovskite devices.

Summary: In this study, the electrocatalytic performance of chromium (Cr) atom anchored to graphyne (Cr@GY) was systematically investigated, revealing that Cr@GY is an efficient NRR electrocatalyst that can activate the inert N equivalent to N bond sufficiently and restrict a competitive hydrogen evolution reaction (HER). The electronic properties were analyzed in detail, and it was found that the co-doping of B and N atoms in GY can reduce the energy barrier of the potential-determining step (PDS) and promote the smooth progress of the NRR, providing theoretical guidance for the synthesis of single-atom catalysts (SACs) with high activity and stability.

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.
