in this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited fecu/cu thin films was investigated. the films were deposited on au2pdag/glass substrates using electrodeposition technique in potentiostatic control. the magnetic fields of 5000 and 7000 oe were applied on deposition bath during deposition. two series of thin films were prepared...

Nowadays, nanodevices like small fluidic channels, semiconductor lasers, nano contacts for solar cells, nano magnets or nano antennas for infrared detection (THz) are of great interest. The applications for these devices extend the fields of e.g. energy, computational or medical sciences. For example, by arranging nano dots consisting of a magnetic material, logical circuits can be designed whi...

The comprehensive search for multifunctional materials has resulted in the discovery of semiconductors and oxides showing ferromagnetic features persisting to room temperature. In this tutorial review the methods of synthesis of these materials, as well as the application of element-specific nano-analytic tools, particularly involving synchrotron radiation and electron microscopy, are described...

Objective(s): In this work, CuO- NiO nano-composites were synthesized via free-surfactant co-precipitation method and then their physiochemical properties, as well as cytotoxicity and antifungal effects, were studied. Methods: The structural and optical properties of CuO-NiO nanostructures were analyzed by X-ray diffraction (XRD), scanning electron micros...

A self aligned nano scale gap between multiple metal layers has been fabricated using a newly developed technique of controlled undercut and metallization (CUM), and applied for the assembly of an individual carbon nanotube (CNT). The new method enables conventional optical lithography to fabricate nano-gap electrodes and self aligned patterns with nano scale precision. Individual CNTs were ass...

in recent years, the scientists have focused on nanotecnology and its applications as the most important fields of research and development. the use of nanoparticles offers many advantages, due to their unique size and physical properties. magnetic iron oxide nanoparticles have been used in many fields, because of their unique properties such as large specific surface area and convenient separa...

The purpose of this paper is to show that semiconductor nano-structures built from non-magnetic InAs/GaAs nano-rings can exhibit simultaneously negative effective permittivity and permeability over a certain optical frequency range. The structures are resonant and have this property near the edge of absorption of the nano-rings. This can be particularly interesting in the investigation of the c...

In this study, we have explored the possibility of the combination of the high reactivity of nano Fe3O4 or Au nanoparticles and daunomycin, one of the most important antitumor drugs in the treatment of acute leukemia clinically, to inhibit MDR of K562/A02 cells. Initially, to determine whether the magnetic nanoparticle Fe3O4 and Au can facilitate the anticancer drug to reverse the resistance of...

Structural distortions in nano-materials can induce dramatic changes in their electronic properties. This situation is well manifested in graphene, a two-dimensional honeycomb structure of carbon atoms with only one atomic layer thickness. In particular, strained graphene can result in both charging effects and pseudo-magnetic fields, so that controlled strain on a perfect graphene lattice can ...

Colour filters based on nano-apertures in thin metallic films have been widely studied due to their extraordinary optical transmission and small size. These properties make them prime candidates for use in high-resolution colour displays and high accuracy bio-sensors. The inclusion of polarization sensitive plasmonic features in such devices allow additional control over the electromagnetic fie...
