Green synthesis of silver nanoparticles using seed aqueous extract of Olea europaea

Biosynthesis of silver nanoparticles with small size and biostability is very important and used in various biomedical applications. In the present work, we describe the synthesis of silver nanoparticles (Ag-NPs) using seed aqueous extract of Olea europaea (Oe) and its antibacterial activity. UV–visible spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), […]

Synthesis, characterization, of Fluorohydroxyapatite nanopowders by sol-gel processing

In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammonium fluoride were used, respectively, as P, Ca, and F precursors with a Ca:P ratio […]
