Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...

We present results of electrochemical deposition of magnetic metals and alloys in the pores of templates prepared by self-assembly from colloidal suspensions of polystyrene latex spheres. This technique has enabled us to create highly ordered magnetic nano-structures with 3D architectures on length scales ranging from 50–1000 nm. Varying the parameters in the preparation (sphere diameter, film ...

According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

We report the fabrication of single-electron tunneling transistors consisting of a single nmscale aluminum particle connected via tunnel junctions to two leads and capacitively coupled to a third gate electrode. We have used these devices to measure the spectra of discrete electronic quantum energy levels in the particle while tuning the number of electrons it contains. c © 1996 Academic Press ...

Electrochemical migration (ECM) of sintered nano-Ag could be a serious reliability concern for power devices with high-density packaging. An anti-ECM nano-Ag-SiOx paste was proposed by doping 0.1wt% SiOx nanoparticles rather than previously used expensive noble metals, e.g., palladium. The ECM lifetime the 1.5 to 3 times longer that nano-Ag, due fact protect Ag from oxidation. thermo-mechanical...

Nanomedicine is the relevance of nanotechnology in the area of healthcare, diagnosis of disease, cure and prevention of disease. Nanotechnology covers the diverse area of matters at dimensions between approximately 1 to 100 nanometers. Nanotechnology has enormous applications in drug delivery field. Nano drug delivery systems can reduce the drug consumption and side-effects by lowering the depo...

The interaction of light with a metal mediated by surface plasmon polaritons provides for sub-diffraction limited optical confinement and control. While the relationship of the linear plasmon response to the underlying elementary electronic excitations of the metal is well understood in general, the corresponding ultrafast and nonlinear plasmon interactions could provide further enhanced functi...
