Ag-Cu solid solutions prepared via ball milling process were subsequently milled for 30 h and investigated by X-ray diffraction technique for Cu-20%Ag, Cu-3.64%Ag and Cu-80%Ag. It was noted that the solid solubility level increased by increasing initial solute content in composition. Results showed peak positions of silver and copper changed with milling time. By heating up to 700 K, ...

Microwave absorbing property of composites containing Ag nanoparticles filled multiwalled carbon nanotube buckypaper (Ag-BP) has been investigated. Buckypaper doped with silver was prepared by direct dispersion and filtration method. From the low temperature resistivity measurement it was found that increasing doping level decreases the electrical conductivity of the buckypaper. 30 wt. % and 40...

This paper presents the optical transmittance properties of thermally evaporated coatings ZnS/Ag nanostructures as a function film thickness and deposition angle designed to mitigate challenges indoor heating their effects on low temperature storage facilities. The were deposited glass by varying both silver zinc sulphide nanofilms at pressure 2.5×10-5 mBars in diffusion pump microprocessor vac...

The extensive use of nanoparticles in a variety of applications has raised great concerns regarding theirbiological effects and environmental fate. Silver nanoparticle, often referred to as nanosilver (n-Ag), maycause health problems because of its wide and ever growing use in many applications. n-Ag is used intreatments of wounds, disinfection of water and/or air and coatings textiles. n-Ag is...

Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processi...

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...
