Fertilization can change the composition of antibiotic resistance genes(ARGs) and their host bacteria in agricultural fields, while complex microbial activities help ARGs into crops and transmit them to humans through agricultural ***, this study constructed a farmland food chain with soil-lettuce-snail as a typical structure, added genetically engineered Pseudomonas fluorescens containing multidrug-resistant plasmid RP4 to track its spread in the farmland food chain, and used different fertilization methods to explore its influence on the spread and diffusion of ARGs and intl1 in the farmland food chain. It was found that exogenous Pseudomonas can enter plants from soil and pass into snails' intestines, and there is horizontal gene transfer phenomenon of RP4 plasmid in bacteria. At different interfaces of the constructed food chain, the addition of exogenous drug-resistant bacteria had different effects on the total abundance of ARGs and intl1. Fertilization, especially manure, not only promoted the spread of Pseudomonas aeruginosa and the transfer of RP4 plasmid levels, but also significantly increased the total abundance of ARGs and intl1 at all interfaces of the constructed food chain. The main ARGs host bacteria in the constructed food chain include Proteobacteria, Bacteroides, and Firmicutes, while Flavobacterium of Bacteroides is the unique potential host bacteria of RP4 plasmid. In conclusion, this study provides a reference for the risk assessment of ARGs transmitted to the human body through the food chain, and has important practical significance to reduce the antibiotic resistance contamination of agricultural products and ensure the safety of vegetable basket. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Phosphonate-based electrolytes with the merits of low cost and intrinsic nonflammability are promising candidates to realize the safe operation of sodium-ion batteries. However, they generally suffer from poor interfacial chemistry because of the solvent-dominated solvation structure induced by the strong ion–dipole interactions between cations and phosphonate molecules. Herein, we report an electrolyte design strategy that selectively improves the competitive coordination of low-solvating–power molecules, achieving stable interfacial chemistry with a non-flammable, low-cost and fluorine-free electrolyte. By improving the ion–ion interaction between cation and anion, weakly coordinated molecules can enter the Na+solvation shell,thereby promoting more adjustable and advantageous interfacial chemistry. As a result, the fluorine-free Prussian blue||hard carbon pouch cell, with a high cathode mass loading of20 mg cm-2, reaches a high capacity retention with an energy density of over 221.7 Wh kg-1based on electrode mass and 115.1 Wh kg-1based on battery mass.

InNi alloy-induced interface effect promoting the parallel electron transfer: improved photothermal catalytic CO2 hydrogenation

引用

science China Chemistry 2025年第6期68卷 2725-2734页

作者： Haoyu Zhang Yu-Hang Li Yu Nie Xinyu Dou Haodong Ji Xin Tan Jinhua Ye Tao Yu School of Chemical Engineering and Technology Tianjin University Eco-environment and Resource Efficiency Research Laboratory School of Environment and Energy Peking University Shenzhen Graduate School School of Environmental Science and Engineering Tianjin University Advanced Catalytic Materials Research Center School of Materials Science and Engineering Tianjin University Research Center for Solar Driven Carbon Neutrality Hebei University

Photothermal catalytic CO2hydrogenation is an effective means of utilizing carbon resources. However, it is severely limited in terms of kinetics and thermodynamics. Therefore, it is necessary to meticulously design catalysts to solve this problem. Herein, a sandwich structured Ni O@In Ni/In2O3is designed to intrinsically regulate the direction of photogenerated carriers transfer,resulting in a CO yield of 42.97 mmol g-1h-1(1290.3 μmol h-1) with a selectivity near to 100%. In Ni alloy favors the collection of photogenerated carriers by the parallel way and enhancement of the adsorption and activation of CO2molecules. NiO grown on the surface of In Ni alloy not only improves the adsorption of H2and provides sufficient H+for the reaction, but also makes In Ni alloy more stable during the reaction process. The photothermal effect caused by In2O3accelerates the transfer of photogenerated carriers and increases the surface temperature of the catalyst, thereby synergistically promoting the reaction from a kinetic perspective. This work ameliorates the kinetic and thermodynamic limitations of the photothermal catalytic CO2hydrogenation process through rationally designing the electron transfer direction of the sandwich structured catalysts to parallel way.
