چکیده انگلیسی
Nanomaterials find applications in multiple fields including food and beverages, waste water management, electrical and electronics due to their interesting properties. These properties can be fine-tuned using various synthesis techniques ranging from solid state route to different wet chemical techniques like precipitation, sol-gel, hydrothermal and solvothermal methods Here, we report a simple wet chemical synthesis of nickel nanoparticles using Tween 80 as the capping agent. Scanning electron microscopy (SEM) revealed a hierarchical nanowire- like morphology with thorn like sharp edges while the presence of nickel in the sample was confirmed by energy dispersive spectroscopy (EDS). X-ray diffraction studies ascertained the crystalline nature of nickel nanowires and also the purity of the as-synthesized nanowires. Transmission electron Microscopy (TEM) and Selected Area Electron Diffraction (SAED) analysis of the sample indicated the existence of a small quantity of nickel hydroxide. The magnetic property of the synthesized nickel samples studied using vibrating sample magnetometer (VSM) revealed a high saturation magnetization of ∼43 emug−1. Antibacterial activity studies confirmed that nickel nanowire exhibited an excellent bactericidal activity against both gram- positive and gram- negative bacteria which could be attributed to the morphology of the nickel nanowires.
