Abstract

In this research was the study of the impact of silver nanoparticles solution on the structure and properties of the morphological membrane fibrous hollow PVDF through a dip PVDF Hollow fiber membrane in silver nanoparticle solution preparation via using laser ablation method. The characteristics of membrane and silver Nano particle solution and was examined using X-ray diffraction (XRD)and Scanning Electron Microscopy (SEM) also using laser particle size analyzer for Silver nanoparticles (AgNPs ) to measurement particle size to AgNPs.

Abstract

ZnO nanostructure were prepared by decomposing zinc hydroxide Zn(OH)2using hexanaldehydeat PH 9 and 105 °C for 10 h. Size of ZnOnano can be like flower or rod controlled by pH of the aqueous solution. Nanostructure of ZnO has been studied bys (SEM), (XRD) and (FTIR). Synthesized Zinc oxide nanostructures possess a hexagonal quartzite temple. ZnO powders were measured by Also using Zeta potential and Particle Size Analyzers and size distribution of the ZnO powder using particle size analyzer (NanoBrook 90Plus Particle Size Analyzer) .

Abstract

It is found silver nanoparticles have strong antibacterial activity due to use in medical applications. It can be tuned antibacterial activity through control the shape and size of the synthesized silver nanoparticles. This article, silver nanoparticles were produced as different sizes at different reaction temperatures by chemical reaction method. Morphology and structure have been characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray diffraction (XRD) and UV-Visible Spectroscopy. Results indicate that silver nanoparticles have different sizes in range of (30- 97.26 nm). Additionally, antibacterial activity test against the pathogens, namely Escherichia colis hows effective inhibitory activity.
