Poly(o-anisidine) molybdophosphate was expediently obtained by sol-gel mixing of Poly(o-anisidine) into the inorganic matrices of molybdophosphate, which was allowed to react with silver nitrate to the formation of poly(o-anisidine) molybdophosphate embedded silver nano composite. The composite was characterized by Fourier Transform Infrared Spectroscopy, X-ray powder diffraction, UV-Vis Spectr...

The 3D printed antibacterial polymer products were rapidly sintered to obtain by selective laser sintering with highly dispersed Nano-silver modified Kaolin powder and polyamide/polypropylene composite engineering material. preparation method of not only shortens the period, but also guarantees precision quality product as well slow-release function Nano-silver.

in order to understand the importance of particle size and agglomeration for nano-eco-toxicological studies in aquatic environments, the acute toxicity of two different types (suspended powder and colloidal) of silver nanoparticles (agnps) were studied in alevin and juvenilerainbow trout. fish were exposed to each type of agnps at nominal concentrations of 0.032, 0.1, 0.32, 1, 3.2, 10, 32, and ...

The influence of SnO2 nanoparticles and method of their introduction in silver matrix on microstructure and physical properties such as density, porosity, hardness and electrical conductivity of Ag-SnO2 electrical contact materials were studied. The SnO2 nanoparticles were introduced by conventional powder mixing and by template method using different templates. All investigated samples were pr...

AIMS The aim of this study was to apply polymer films containing silver nanoparticles as a new method for increasing the shelf life and preserving the quality of export/commercial products of Kerman Province and determine the ideal temperature for preserving these products. METHODS After preparing nano-composite films containing silver nanoparticles (3% and 5% by weight), Mazafati dates were ...
