In this work, porous nanoparticles of ferrite cobalt were prepared by dissolving CoCl2.6H2O and FeCl3 in ethylene glycol in a hydrothermal process. Using ethylene glycol instead of DI water as a solvent would cause to provide porous structure of ferrite cobalt. 0.05 ml of colloidal fluid of fabricated nanostructure was injected on interdigitated electrodes (IDE) on a printed circuit board (PCB)...

The aim of this study is to evaluate the influence of pH on the synthesis of nanocrystallines cobalt ferrite by combination of sol- gel auto combustion and ultrasonic irradiation methods. Two different fuels, urea and thiourea, along with metal nitrates (oxidant) were used to prepare CoFe2O4 powders. The morphology of the resulting powders was investigated. The powders wer...

Cobalt ferrite, Copper ferrite and cobalt doped copper nanoparticles have been synthesized characterized using different characterization methods (XRD, FTIR FESEM). The prepared used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. PVDF/(Cu–CoFe2O4, CoFe2O4, CuFe2O4) nanocomposites films via a simple solution casting technique. optical properties piezoelectric response nanoco...

The magnetic properties of calcined cobalt ferrite formed by nano-crystalline powders have been compared by two different methods (co-precipitation and hydrothermal). The structural properties of the produced powders were investigated by X-ray Diffraction (XRD), scanning electron microscopy (SEM). The results show that the formation of cobalt ferrite spinel structures is effected by changing me...

This paper analyzes the effective radiation efficiency of a ground-penetrating radar (GPR) consisting of two resistor-loaded bow-tie antennas covered with a ferrite-coated conducting cavity by using finite-difference time-domain (FDTD) method. The GPR is located above a lossless or lossy ground surface. The relation between the radiation powers into the ground and air, dissipated powers at the ...

Cobalt ferrite (CoFe2O4) nanorods were synthesized by iron chloride (FeCl3.6H2O) and cobalt sulfate hexahydrate (CoSO4.7H2O) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (PVP) surfactant. The samples were characterized to identify the physical properties. XRD pattern of cobalt ...

Research funded by this award focused on the synthesis of unique plasmonic nanoparticles, preparation of core-shell particles to enhance the generation of hydrogen via the photocatalytic splitting of water, and mechanistic studies of the charge transfer of such core-shell particles. A particular emphasis centered on the synthesis and study of hollow gold-silver nanoshells (GSNSs) having tunable...

A multitude of nanoparticles, such as titanium oxide (TiO2), zinc oxide, aluminum oxide, gold oxide, silver oxide, iron oxide, and silica oxide, are found in many chemical, cosmetic, pharmaceutical, and electronic products. Recently, SiO2 nanoparticles were shown to have an inert toxicity profile and no association with an irreversible toxicological change in animal models. Hence, exposure to S...
