Summary: Eutrophication caused by excessive discharging of phosphorus is a global water pollution problem. A magnetic thermal modified palygorskite nanocomposite (MTPG) was fabricated to enhance phosphorus adsorption capacity and facilitate separation from liquid. Results showed abundant nano-scale Fe3O4 loading on the surface of thermal modified palygorskite, leading to doubled specific surface area. MTPG exhibited pH-dependent phosphate adsorption with a maximum adsorptive quantity of 400.00 mg/g.

Summary: The use of mustard seeds functionalized with TOA as an adsorbent (TOA-M)-BR effectively removed Cr(VI) from sulfate media. The process followed pseudofirst-order rate and complied with Langmuir isotherm, demonstrating feasible, spontaneous, and endothermic adsorption. Operating conditions also allowed efficient separation of Cr(VI) from other fission products.

Summary: In this study, a composite biochar with enriched surface functional groups was prepared from shrimp shell and rice husk for efficient adsorption of p-nitrophenol. The composite biochar exhibited excellent adsorption performance in a wide pH range, and the pseudo-second-order kinetic model and Langmuir isotherm model were suitable for describing the adsorption behavior. The adsorption mechanisms involved chemisorption, physical adsorption, and pore filling. The tailored surface chemistry and high-efficiency of the composite biochar make it a potential candidate for water body remediation via adsorption process.

Summary: This study used common disposable polypropylene (PP) rice boxes as a source of microplastics (MPs) to investigate the sorption and desorption behavior of nonylphenol (NP) on pristine and naturally aged PPs in summer and winter. The results showed that summer-aged PP had more pronounced property changes compared to winter-aged PP. The sorption capacity of NP on PP was summer-aged PP > winter-aged PP > pristine PP. Aged MPs exhibited stronger sorption capacity due to a larger specific surface area, stronger polarity, and more oxygen-containing functional groups facilitating hydrogen bonding with NP. Desorption of NP in simulated intestinal fluid was significant, with summer-aged PP > winter-aged PP > pristine PP. Hence, aged PP poses a greater ecological risk.

Summary: The aim of this study was to investigate the isothermal forward martensitic transformation in NiTi-based shape memory alloys with different compositions, and explore its origin. The results showed that the transformation only occurred in alloys with substitutional defects. The presence of a critical concentration of copper effectively suppressed the martensitic transformation. The thermodynamics of the transformation with and without substitutional defects were discussed, and the influence of substitutional defects on the transformation was clarified. It was found that the formation of martensite during isothermal holding was due to local fluctuation of substitutional defect concentration. The study also confirmed that the maximum volume fraction of the martensite was limited by the thermal elastic equilibrium in alloys without substitutional defects.

Summary: The adsorption behaviour of gadolinium on grafted co-polymers was studied. Addition of silica improved the adsorption capacity, with the highest capacity observed for the polymer containing polyacrylamide, acrylic acid, sodium styrene sulfonate, and silica gel. The adsorption process followed the Langmuir model, and the sorption kinetics were described by the pseudo-second order model. The temperature had a positive effect on gadolinium removal, indicating an endothermic sorption process.

Summary: The MgH2-CCPA composite, synthesized through hydrogen combustion and mechanically ball-milled method, exhibited improved hydrogen sorption characteristics due to the in situ formed amorphous carbon. The dehydrogenation temperature and kinetics of the composite were significantly enhanced compared to pure milled MgH2, with higher hydrogen liberation and absorption capacities. The presence of amorphous carbon in the MgH2-CCPA composite contributed to the notable improvement in sorption kinetics.

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.
