Summary: Precise assembly of silver nanoparticles in electrospun nanofiber films was achieved by dual-energy irradiation of ultraviolet and heat. Heat irradiation promoted the uniform distribution and growth of AgNPs, while UV irradiation caused the directional arrangement of silver nanocrystals. Assembled silver nanolines with chain, bundle, and fringe shaped architectures were successfully prepared by combining the dual-energy irradiation.

Summary: Polyethylene terephthalate (PET) is widely used in medicine, engineering, and food due to its biocompatibility and mechanical resistance, but it lacks antimicrobial properties. In this study, PET film was functionalized with amino groups and a dicarboxylic acid, and then grafted with chitosan chains. The chitosan coating was loaded with silver nanoparticles, resulting in materials with good cell viability and potential bacteriostatic activity.

Summary: Zinc oxide photocatalysts synthesized using banana peel waste extract as reducing and capping agents exhibit superior photocatalytic activities in degrading hazardous dyes compared to chemically synthesized ZnO. Various spectroscopic and microscopic techniques confirmed their formation and morphologies, with biologically synthesized ZnO showing smaller crystallite size and higher surface area. The environmentally friendly catalyst is economically viable for organic contaminant removal in wastewater treatment under visible light irradiation.
