Summary: This study presents a facile fabrication strategy for a three-dimensional reduced graphene oxide hydrogel embedded with lignin nanoparticles (LNP), which exhibits promising potential for environmental applications. The LNP were synthesized from walnut shell waste via a direct chemical method and were integrated into the continuous porous network of rGO to create the rGO@LNP hydrogel. Various analytical techniques were employed to characterize the structure and properties of the hydrogel. The efficiency of the hydrogel as an adsorptive platform was evaluated using methylene blue and Pb2+ as model pollutants, and its antibacterial activities were also tested. The results demonstrated that the inclusion of LNP significantly enhanced the pollutant's uptake ability of the hydrogel and exhibited improved bactericidal effect compared to bare LNP and rGO. This innovative approach utilizing the synergy of functional properties of LNP and rGO has great potential for water filtration and remediation.

Summary: The application of nanosilicon has been found to enhance plant defenses against various stresses. Silicon quantum nanodots, with their unique biological and physiochemical properties, show promise in regulating plant responses to stress. By studying maize, it was observed that the addition of Si NDs and sodium silicate effectively inhibited the growth of caterpillars and activated defense genes. Field experiments also demonstrated the potential of Si NDs in increasing maize yield. These findings suggest that Si NDs can be an effective and ecofriendly crop protection strategy in agroecosystems.

Summary: Flow fields greatly affect the performance and pumping consumption of flow batteries. This study developed a three-dimensional model to optimize the interdigitated flow field for high-performance flow batteries. The results show that large aspect ratios and small channel fractions improve battery performance, but excessively large aspect ratios lead to uneven distribution of reactants. Considering both electrochemical loss and pumping consumption, flow fields with unit widths from 1.5 to 2.5 mm and channel fractions from 0.125 to 0.375 achieve the lowest total power loss.

Summary: Loss of crop yield to pathogen damage seriously threatens efforts to achieve global food security. In this study, La-based nanomaterials with different morphologies and compositions were investigated for their control of bacterial pathogen Ralstonia solanacearum on tomato. Foliar application of LaPO4 nanorods significantly suppressed pathogen infection, and the disease control efficacy of different La-based nanomaterials varied. Mechanistically, LaPO4 nanorods supplied low levels of La ions to activate calmodulin and enhance phenylalanine ammonia lyase activity and pathogenesis-related gene expression. Additionally, La-based nanomaterials increased flavonoid and polyphenol content and antioxidative enzyme activity, reducing oxidative stress in tomato shoots. The higher disease control ability of LaPO4 nanorods was attributed to its bioavailability, slow-release ability, and P nutrient supplement. These findings highlight the importance of tuning nanomaterial morphology and composition for optimal sustainability and efficacy.

Summary: Oxygen nanobubble-loaded biochars have been found effective in reducing copper toxicity in paddy soils and improving crop productivity. This amendment improves the redox potential and dissolved oxygen concentration in the rhizosphere, promotes root iron plaque formation, and inhibits copper influx. It also enhances soil microbial diversity and increases bacterial genes abundance involved in copper complexation and export. The sequestered copper in root iron plaque and soil bacteria prevents its accumulation in edible parts of the plants.

Summary: Improving the inclusiveness of urban development is crucial for enhancing the wages of low- and middle-income workers. This study utilized machine learning to classify urban labor into low, middle, and high socioeconomic groups in order to examine the effects of economic agglomeration and compare them with income-based classifications. The findings revealed that economic agglomeration has positively impacted the wages of low and middle socioeconomic groups, with an estimated wage spillover effect of 3.9%. However, the spillover effect of economic agglomeration was overestimated when based solely on income classifications, with an estimated effect of 20.3%. This overestimation often misrepresents the inclusiveness of China's urbanization. Further analysis identified that the characteristics of the industrial structure moderate the change in wage elasticity caused by economic agglomeration, which consequently contributes to wage disparities in China.

Summary: In this study, the degradation behavior of glyphosate in Vulpia myuros cultivated in a hydroponic system was investigated. The results showed that V. myuros could absorb glyphosate, and the concentration of glyphosate in the plant decreased over time. The degradation dynamics of glyphosate fitted a first-order kinetic model, with a half-life of 5.08 days. The content of the glyphosate metabolite did not change significantly over time. These findings suggest that V. myuros has the potential to be used as a remediation plant for environmental restoration.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
