The geometry of quasi-spherical nanoparticles is investigated. The combination of SEM imaging and electrochemical nano-impact experiments is demonstrated to allow sizing and characterization of the geometry of single silver nanoparticles.

The use of plant extracts for the synthesis of nanoparticles plays a significant role in nanotechnology field as it is simple, fast, environment friendly and no use of toxic chemicals. The current research work investigate the findings of optimization of different experimental variables conditions like reaction pH, silver nitrate concentrations, time, temperature and mixing ratio of the reactan...

rose (rosa hybrida l.) is one of the mostly cultivated cut flowers in iran and around the world. the study was carried out to increase the vase life and quality of cut rose ‘grand prix` and ‘avallanche` by using various floral preservative solutions. floral preservative solutions were agno3, 8-hqs, nano silver and distilled water. treatments were compared with tap water as control. the experime...

Silver coordination polymer chains were deposited on Au(111) as a model surface, as well as on gold alloy and titanium as dental implant and restorative materials. The topography of the surface was analysed on the model substrate and it was found to be a nano-structured crystalline material. In vitro investigations in a flow chamber imitating the oral environment prove the anti-bacterial proper...

This study was designed to probe the fabrication of unique silver and gold nano-structures engaging a self-designed chitosan-porous anodic alumina nano-composite as a template. Porous anodic alumina has been manufactured by di-step aluminum anodization in an oxalic acid electrolytic bath. The surface properties of porous anodic alumina were reinforced by chitosan neutralized in sodium hydro...

The developed bio-field effect transistor (BioFET) consists in nano-silver ink printed source and drain electrodes, a polymeric organic semiconductor, dielectric layer based on methyl methacrylate (MMA) and finally the reference electrode of silver-silver chloride ink. The thickness of the dielectric layer was optimized and characterized by Scanning Electron Microscopy (SEM) and by electrical m...

Powered by UV light, nano/micrometer-sized silver chloride particles exhibit autonomous movement and form "schools" in aqueous solution, i.e. regions in which the number density of particles is significantly higher than the global average. In this paper, the silver chloride particles in such a system are classified by their proximity to other AgCl particles--be they isolated, coupled or schoole...

During the last couple of years several ink manufacturers have presented metal nano-particle inks for inkjet printing. These inks provide low resistances on plastic and paper substrates, thus enabling manufacturing of high-conductivity conductors that could be used in circuit boards. Inkjet printing of a commercial silver nano-particle ink on paper and plastic substrates has been investigated. ...

As an important interconnection material in electronics, conductive silver paste has attracted much research interest chip packaging and printed circuit board due to its predominant properties like high conductivity flexible interconnection. In this paper, the nanoparticles, sphere particles, flake powders are fabricated by various methods. Different proportions of powder selected prepare micro...

Biofilm formation on implant materials causes a common problem: resistance to aggressive pharmacological agents as well as host defenses. Therefore, to reduce bacterial adhesion to implant surfaces we propose to use silver(I) coordination networks as it is known that silver is the most powerful antimicrobial inorganic agent. As a model surface, self-assembled monolayers (SAMs) on gold Au(111) w...
