On the basis of these facts about freshwater fish and invertebrates: (i) the Na+ turnover is a physiological process associated with the gill membranes; (ii) the key mechanism of acute silver toxicity consists of reduction in Na+ uptake by blockade of gill Na+,K+-ATPase; (iii) the mass-specific surface area of the gills depends on animal body mass; and (iv) the gill surface is also the major si...

Mango and neem leaf extract were prepared by soaking the measured leaves into 100ml of distilled water under appropriate conditions. Consequently, biosynthesis silver nanoparticles was carried out distinctly adding mango to solution nitrate (AgNO3) produce aqueous dispersion nanoparticles. The produced investigated using FTIR, UV-Visible AFM Spectroscopy at 15 minutes, 24 hours 48 respectively....

The task of this article is to update, develop and introduce into scientific practice the method "mechanochemical recrystallization" in solid-phase systems with small additives liquid phase solvent precursors stabilize formed nanoparticles. essence shown using example mechanical activation S–AgNO3–NH4X system, where X = Cl, Br, I, addition dimethyl sulfoxide (DMSO), resulting mechanochemical sy...

Economically viable and eco-friendly Mesona Blumes (M.B.) gum was employed to synthesize AgNPs. The synthesis parameters such as concentration of silver nitrate (AgNO3), M.B. gum, microwave irradiation time pH...

The promotive effect of AgNO3 and aminoethoxyvinylglycine (AVG) on in vitro shoot regeneration from cotyledons of Brasska campestris ssp. peklnensls in relation to endogenous 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, ACC, and ethylene production was investigated. AgNO3 enhanced ACC synthase activity and ACC accumulation, which reached a maximum after 3 to 7 days of culture. ACC accu...

On an AgNO3 crystal, an equilateral or a right-angle triangle-shaped Ag trimer was selectively fabricated through near-field photo-reduction and observed in situ by using an apertured cantilever coupled with an atomic force microscope. By using the different triangle-shaped Ag trimers, irradiation wavelength and polarization dependence of surface-enhanced Raman scattering were investigated.

In this study, the minimum inhibitory concentrations (MICs) of AgNO3 against bacteria were investigated in a variety of microorganism culture broths. Broth- and light-dependent MIC values were observed and correlated negatively with nano-Ag speciation development. We advocate here the importance of broth and light standardization in Ag antimicrobial test.

An efficient and stereoselective synthesis of vinylphosphonates and phosphine oxides was developed starting from styrenes using AgNO3 as the catalyst and K2S2O8 as the oxidant. The success of the reaction was found to be critically dependent on the use of TEMPO as the additive.

INTRODUCTION Application of nanoparticles has been extensively increased in last decades. Nanoparticles of noble metals such as gold, platinum and especially silver are widely applied in medical and pharmaceutical applications. Although, variety of physical and chemical methods has been developed for production of metal nanoparticles, because of destructive effects of them on environment, biosy...

A nanosilver composite plant medium with a good antimicrobial capability was successfully prepared via a two-step method in this work. First, nanosilver particles were prepared in a silver nitrate (AgNO3) solution by using D-glucose as a reduction reagent at room temperature. The effect of AgNO3 concentration levels on the size of the nanosilver particles was investigated. The sedimentation act...
