Uniform three-dimensional superstructures of spherical cobalt nanocrystals are produced by the interplay between dipolar interaction and applied magnetic field. An anomalous low-temperature magnetic behavior is observed, indicating that uncompensated surface spins become ordered below 10 K, as evidenced by the presence of two magnetic phases that superimpose in hysteresis loops as compared to m...

Schwann cells (SCs) are attractive seed cells in neural tissue engineering, but their application is limited by attenuated biological activities and impaired functions with aging. Therefore, it is important to explore an approach to enhance the viability and biological properties of SCs. In the present study, a magnetic composite made of magnetically responsive magnetic nanoparticles (MNPs) and...

Discharge of dye effluents into the natural streams may be toxic to the aquatic lives as well as human being. In the present studies, zeolite was synthesized from coal fly ash by alkaline hydrothermal treatment and mixed with magnetite nanoparticles in suspension to produce zeolite-iron oxide magnetic nanocomposite. It was used as adsorbent for the removal of malachite green dye from aqueous so...

In this research, the surface stress effect on the nonlocal vibration of piezoelectric square plate reinforced by single walled carbon nanotubes (SWCNTs) based on classical plate theory (CPT) and first order shear deformation theory (FSDT) is presented. The elastic properties of piezoelectric nanocomposite plate are estimated by Eshelby-Mori-Tanaka and the extended mixture rule approaches. The ...

organic solvents. In this study, NiFe2O4/sawdust nanocomposite was synthesized for removingoil pollutants. The oil-adsorbing nanocomposite could be easily separated from water bymagnet bar. The XRD results show tetragonal phase proving the composite formation. TheFESEM pictures successfully reveal the growth of NiFe2O4 on the sawdust template. The FTIRbands at 422 cm-1 and 615 cm-1correspond to...

In the present study, the magnetic field effects of the elastic response of the polymeric piezoelectric cylinder reinforced with the carbon nanotubes (CNTs) are studied. The cylinder is subjected to an internal pressure, a constant electric potential difference at the inner and outer surfaces, and the thermal and magnetic fields. The Mori-Tanaka model is used for obtaining the equivalent materi...

One of the grand challenges in the development of nanotechnology is how to synthesize and process “designed nano-structured” materials. An important example of these materials is the nanocomposite permanent magnets made of hard and soft phased magnetic nanoparticles located on a superlattice. Binary phase magnets, if they can be devised, could double the energy product of current single-phase m...
