cu2o nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used as solvent and reductant. span 80 was applied to control the morphology of cuprous oxide nanoparticles. the nano structure of the complex was characterized by x-ray diffraction measurement...

Antibacterial activity of Fe3O4 nanoparticles was investigated in three microorganisms including P. aeruginosa, E. Coli and Staphylococcus aureus. Fe3O4 nanoparticles were synthesized by chemical precipitation method (20 nm). The Fe3O4 nanoparticles antibacterial effect against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were studied by the culture method. First of all, e...

Nanofibers are one-dimensional nanomaterial in fiber form with diameter less than 1 µm and an aspect ratio (length/diameter) larger than 100:1. Among the different types of nanoparticle-loaded nanofiber systems, nanofibers loaded with magnetic nanoparticles have gained much attention from biomedical scientists due to a synergistic effect obtained from the unique properties of both the nanofiber...

Extinction coefficients of gold nanoparticles with core size ranging from approximately 4 to 40 nm were determined by high resolution transmission electron microscopy analysis and UV-vis absorption spectroscopic measurement. Three different types of gold nanoparticles were prepared and studied: citrate-stabilized nanoparticles in five different sizes; oleylamide-protected gold nanoparticles wit...

In this research the effects of adding silica and alumina nanoparticles on flow ability and compressive strength of cementitious composites based on Portland cement were investigated. In the first stage, the rheological behavior of different samples containing nanosilica, nanoalumina and polypropylene, polyvinyl alcohol and polyethylene fibers were evaluated. With increasing of nanoparticles in...

This review discusses briefly the preparation, electrochemistry, and electrogenerated chemiluminescence (ECL) as well as spectroscopic properties of organic nanoparticles. Organic nanoparticles, ranging from several tens of nanometers to hundreds of nanometers in diameter, were successfully prepared by various methods. Using a simple reprecipitation method, organic nanoparticles of a very small...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

The present study aims at study on combined effect of zinc oxide nanoparticles (ZnO) with common agricultural fungicides. Nanoparticles were synthesized using chemical reduction process and characterized by UV-Visible spectroscopy, X-ray diffraction (XRD), Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM). Synthesized nanoparticles were observed to be in size range of 12...
