The roles of silver ions and halides (chloride, bromide, and iodide) in the seed-mediated synthesis of gold nanostructures have been investigated, and their influence on the growth of 10 classes of nanoparticles that differ in shape has been determined. We systematically studied the effects that each chemical component has on the particle shape, on the rate of particle formation, and on the che...

background: investigation of toxicity of silver nanoparticle, especxially blood toxicity, is necessary because this nanoparticle is used a lot in diffrerent parts of life and invironment. the aime of this is evaluation the effects of silver nanoparticles with different concentrations on blood cells pregnant wistar rats. materials and methods: in this case control study, 30 pregnant rat were div...

in the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. to this purpose, the governing partial differential equations were converted to a set of nonlinear differential equations using similarity transforms and were then analytically solved. it was found...

because of high cost of drilling and analysis of samples, it needs to predict gold and silvers based on pathfinder such as as, sb, cd, pb and zn and decrease the cost and time exploration project implementation. in this paper, the model based on a multilayer perceptron artificial neural network (mlp-ann) optimized by invasive weed optimization algorithm (iwo) to predict of gold and silver in za...

Gold and Silver nanoparticles (AuNPs AgNPs) are perfect platforms for developing sensing colorimetric devices thanks to their high surface volume ratio distinctive optical properties, particularly sensitive changes in the surrounding environment. These characteristics ensure sensitivity devices. Au Ag can be capped with suitable molecules that act as specific analyte receptors, so highly select...

Abstract Rapid synthesis of nanomaterials in scalable quantities is critical for accelerating the discovery and commercial translation nanoscale-based technologies. The metal nanogold silver volumes larger than 100 mL not automatized might require use harsh conditions that most cases detrimental production nanoparticles with reproducible size distributions. In this work, we present development ...

This project is an extension of TEM work conducted on a previous AINSE funded project AINGRA08066, and aims to use the TEM, STEM/HAADF, EDS and plasmon imaging facilities at ANSTO to structurally characterize novel supported silver nanoparticle catalysts for ozone abatement, and supported gold catalysts for low temperature CO oxidation. The catalysts, fabricated at the University of Auckland, c...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...

We report the growth of well-oriented nest (reticulum)-like and lotus flower-like submicron structures of ZnO, over gold and silver nanoparticle assemblies, respectively. The structures were grown by a convenient chemical bath deposition method in a nutrient solution made of zinc nitrate (Zn(NO3)2 Æ 6H2O) and methyl amine (CH3NH2) at low temperature. SEM, XRD, Raman, UV–Vis and fluorescence spe...
