The microtubes are important structures in nano electromechanical system .in this study a nonlocal model is presented to investigate the static torsion behavior of microtubes made of bi-directional factionally graded material (BDFGM) subjected to a longitudinal magnetic field. Mechanical properties of BDFGM microtube varies in the radial and longitudinal direction according to an arbitrary func...

Nano Magnetic Logic (NML) has been attracting application in optical computing, nanodevice formation, and low power. In this paper nanoscale architecture such as the decoder, multiplexer, and comparator are implemented on perpendicular-nano magnetic logic (pNML) technology. All these architectures with the superiority of minimum complexity and minimum delay are pointed. The proposed architectur...

In this research, analysis of nonlocal magneto-electro-thermo-elastic of a functionally graded nanobeamdue to magneto-electro-elastic loads has been done. In order to formulate the problem the Timoshenko theory of beams is utilized. The principle of virtual work, Hamilton’s principle as well as nonlocal magneto-electro-thermo-elastic relations has been recruited to derive the governing eq...

In this study, a ZnO@Ag2O@Fe3O4 nanocomposite as an innovative magnetic solid phase extraction agent was introduced. The structural and morphological properties of the as-prepared nano-sorbent were characterized using X-ray diffraction analysis, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and nitrogen adsorption–desorption techniques. The synthesized mag...

Current induced spin wave excitations in spin transfer torque nano-contacts are known as a promising way to generate exchange-dominated spin waves at the nano-scale. It has been shown that when these systems are magnetized in the film plane, broken spatial symmetry of the field around the nano-contact induced by the Oersted field opens the possibility for spin wave mode co-existence including a...

Abstract Substances with superparamagnetism, a special magnetic effect, are magnetized under external field. When the applied field disappears, superparamagnetic substances have almost zero magnetization intensity, quite small coercivity. The performance of powder or suspension used in particle detection greatly affects sensitivity. This paper studies new method for preparing nano-superparamagn...

Magnetospirillum sp. strain AMB-1 is a Gram-negative alpha-proteobacterium that synthesizes nano-sized magnetites, referred to as magnetosomes, aligned intracellularly in a chain. The potential of this nano-sized material is growing and will be applicable to broad research areas. It has been expected that genome analysis would elucidate the mechanism of magnetosome formation by magnetic bacteri...

BACKGROUND Chitosan nanoparticles have become of great interest for nanomedicine, biomedical engineering and development of new therapeutic drug release systems with improved bioavailability, increased specificity and sensitivity, and reduced pharmacological toxicity. The aim of the present study was to synthesis and optimize of the chitosan nanoparticles for industrial and biomedical applicati...

Three-dimensional (3D) nanomagnetism, where spin configurations extend into the vertical direction of a substrate plane allow for more complex, hierarchical systems and the design of novel magnetic effects. As an important step towards this goal, we have recently demonstrated the direct-write fabrication of freestanding ferromagnetic 3D nano-architectures of ferromagnetic CoFe in shapes of nano...
