Summary: CuFeO2-ZnO heterostructures were successfully fabricated using a two-step precipitation-hydrothermal process, exhibiting enhanced photocatalytic performance compared to pure ZnO and CuFeO2. The 5% CuFeO2-ZnO heterostructure showed the best photocatalytic efficiency, with a faster degradation rate and higher charge carrier lifespan than CuFeO2 and ZnO. The presence of Type I heterostructures and outstanding recyclability further highlight the significance of forming p-type CuFeO2 and n-type ZnO heterostructures for improved photocatalysis.

Summary: Fresh vegetables and fruits often require modified atmosphere packaging (MAP) to extend their shelf life and preserve freshness. MAP changes the concentration of CO2 and O2, as well as increases moisture preservation. It also helps isolate the product from the surrounding environment, reducing the risk of contamination and physiological damage. MAP design involves considering factors such as film permeability, optimal gas concentrations, and respiration rate to create the best packaging environment.

Summary: A novel magnetically recoverable copper nanocatalyst was synthesized by immobilizing a copper complex on the surface of silica-coated magnetic nanoparticles modified with a novel Schiff base ligand [Fe3O4@SiO2-bis(aminopyridine)-Cu]. Various characterization techniques were used to analyze the structure of the synthesized [Fe3O4@SiO2-bis(aminopyridine)-Cu(II)] nanocomposite. Catalytic studies demonstrated that the Fe3O4@SiO2-bis(aminopyridine)-Cu(II) nanocomposite exhibited excellent efficiency and green catalytic activity for the synthesis of benzothiazoles and polyhydroquinolines. The nanocatalyst could be easily recovered through magnetic separation and maintained its catalytic activity for at least 6 cycles.
