hydrous manganese dioxide nanoclusters are prepared by the oxidation of manganese (ii) ions with ammonium persulfate and used as a new sorbent for ag+ ion removal from aqueous medium. the synthesized compound is characterized using scanning electron microscopy, dynamic light scattering, energy dispersive analysis of x-rays, x-ray diffraction and bet surface measurements. scanning electron micro...

This research study is mainly targeted on fabrication and characterization of antibacterial poly(e-caprolactone) (PCL) based fibrous membrane containing silver chloride particles. Micro/nano fibres were produced by electrospinning and characterized with TGA, DSC, SEM and mechanical analysis. It was found that addition of silver particles slightly reduced onset of thermal degradation and increas...

A new method is proposed for the simple preparation of random silver micro and nano-electrode arrays. This employs acoustic streaming directed at a glassy carbon surface to "mechanically" attach particles from a suspension of metal colloidal or other small particles. The particles tend to adhere to the substrate at points of imperfection such as scratches, crevices etc. These arrays are compare...

Recently, development of reliable experimental protocols for synthesis of metal nanoparticles with desired morphologies and sizes has become a major focus of researchers. Green synthesis of metal nanoparticles using organisms has emerged as a nontoxic and ecofriendly method for synthesis of metal nanoparticles. The objectives of this study were production of silver nanoparticles using Pinus eld...

This research is reports the fungicidal properties of nano-size silver/chitosan nanoformulations (NFs) used as an agent for antifungal treatment of various seed borne plant pathogens. Fungal phytopathogens, especially seed borne disease causing species, Rhizoctonia solani, Aspergillus flavus, Alternaria alterneta were isolated form chickpea seeds. Differences were observed in the antifungal act...

in order to study the effects of silver thiosulfate (0.02, 0.05, 0.1 and 0.2 mm), humic acid (100, 500 and 1000 mg l-1), nano silver (5, 10, 25 mg l-1), salisilicacid (1, 2 and 4 mm) and sucrose (1%, 2.5% and 5%) on the vase life and some qualitative characteristics of cut narcissus var duch master floweres, two expriments were counducted in postharvest laboratory of mohaghegh ardabili universi...

In this work, two natural sources, including pomegranate peel extract and cochineal dye were employed for the synthesis of silver nanoparticles. The natural silver complex from pomegranate peel extract resulted in nano-sized structures through solution-phase method, but this method was not efficient for cochineal dye-silver precursor and the as-formed products were highly agglomerated. Therefor...

In this study, the antimicrobial activity of colloidal silver nanoparticles prepared by the sol-gel method was investigated, and the turbidity, viscosity and pH of the colloidal solutions were determined. The size of the silver nanoparticles was measured by Atomic Force Microscopy (AFM). The minimum inhibitory concentration (MIC) value of the colloidal solution resistance to test microorganisms...
