Background and Objectives: Heavy metals are the most common contaminants in industrial wastewater. Cadmium is important due to its toxicity and harmful effects on human beings. The aim of this study was to evaluate the removal of cadmium from aqueous solutions by nickel ferrite-titanium oxide nanocomposite. Materials and Methods: This experimental – laboratory study was carried out in a ...

The morphology, structure, and magnetic properties of nickel ferrite (NiFe2O4) films fabricated by radio frequency magnetron sputtering on Si(111) substrate have been investigated as functions of film thickness. Prepared films that have not undergone post-annealing show the better spinel crystal structure with increasing growth time. Meanwhile, the size of grain also increases, which induces th...

In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...

A ferrite loaded accelerating cavity with a frequency sweep of 18 to 40MHz is studied for a possible upgrade of the CERN accelerator complex. The resonance frequency of a ferrite loaded cavity shifts by applying an external magnetic bias field to the ferrite material by means of changing the relative permeability. We present the electromagnetic design of such a cavity with a special emphasis on...

The stability of suspensions of nickel ferrite spheres is investigated for different compositions of the dispersion medium, in the absence and in the presence of an external magnetic field. The time-dependence of the optical absorbance of the suspensions is the quantity used for experimentally determining the stability. Two approaches have been used for the calculation of the interaction energy...

Zinc nickel alloy was deposited from alkaline bath at a PH of 13-14 with the nickel percentage of 5-9% in our prior research. Present study dealt with the research on 10-12% of Nickel at a PH of 12-13 from Zinc – nickel alloy electrolyte and the remaining percentage of Zinc, required for corrosion resistant applications to be used for reliable alternative of cadmium. Hull cell studies was carri...
