In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

in this paper, the hartree-fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. the bare coulomb interaction between electrons has been assumed. for this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...

recent investigations have been shown that inorganic nanomaterials including gold nanoparticles, nonporous and mesoporous silica nanoparticles, magneticnanoparticles, and quantum dots have shown great potential in bioimaging, targeted drug delivery, and cancer therapies. biocompatibility, ease of synthesis, and ease of surface functionalization are among the significant properties of nonporous ...

Anodic aluminum oxide (AAO) fabricated by two step anodization technique, is used as a template to synthesize FeCo nanowire arrays by AC electrodeposition technique. Response surface methodology (RSM) is applied to design the experiments, fit an empirical model and optimize the conditions to achieve the best magnetic properties. The magnetic properties, pore dimensions, composition and structur...

in this work, we report synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, cetyltrimethylammonium bromide ctab as cationic surfactant and butanol as a cosurfactant. silica surface modification of the as prepared nanoparticles was performed by adding tetraethoxysilane teos to alkaline medium. the struct...

soil drainage conditions significantly affect the chemical properties of soil, particularly type and the extent of iron oxides. soil magnetic susceptibility (?) has a close relationship with drainage conditions. eight soil profiles, in four regions of fars province, with aquic and non-aquic soil moisture regimes were studied to determine the effect of drainage conditions on ? and on chemical fo...

background: multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. a rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles.objectives: herein, we report on a simple approach for the synthesis of ma...

the main objective of this research was to synthesize and characterize gold-coated fe3o4 /sio2 nanoshells for clinical applications. magnetite nanoparticles (nps) were prepared via co-precipitation. the results showed that smaller particles can be synthesized by decreasing the naoh concentration, which in our case this corresponded to 35 nm by using 0.9 m of naoh at 750 rpm. the nps were then m...

an efficient method for purification of yard-glass shaped boron nitride nanotubes (yg-bnnts) fabricated via a chemical vapour reaction (cvr) route has been developed. impurities including carbon, boron nitride (bn), and fe species in the pristine yg-bnnt sample are removed by a combined physical and chemical procedure which involves ultrasonication, high temperature oxidation, hot-water washing...
