Keywords Ferrite; Photoluminescence; nanoparticles; auto-combustion; spectroscopic properties The spinel Ni-ferrite with different synthesizing temperature was synthesized by the glycine-nitrate auto-combustion process. X-ray diffraction, field emission-scanning electron microscopy, Fourier transform-infrared spectroscopy and Photoluminescence anal...

In this paper, mixed spinel Co0.4Zn0.6Fe2O4 ferrite was synthesized by microwave-assisted combustion method. Photocatalytic activity of the as-synthesized sample was investigated against methylene blue dye at room temperature at different exposure times (60-360 min.) under visible light. Phase impurity and surface morphology which are investigated...

In this paper, mixed spinel Co 0.4 Zn 0.6 Fe 2 O 4 ferrite was synthesized by microwave-assisted combustion method. Photocatalytic activity of the as-synthesized sample was investigated against methylene blue dye at room temperature at different exposure times (60-360 min.) under visible light. Phase impurity and surface morphology which are invest...

We report on the enhance magnetic properties of synthesized Mg-Ferrite catalyst through the microwave-assisted combustion route by making nanocomposite via Zn-ferrite. The gravimetric oil removal capability tests from water at room temperature were performed. Phase impurity and surface morphology which investigated with XRD analysis and field emiss...

We report on the role of (poly (vinyl pyrrolidone, PVP)) on the structure, morphology and magnetic properties of MgFe2O4@ZnFe2O4 nanocomposite ferrite through the microwave-assisted combustion route. Phase impurity, surface morphology, and magnetic properties which investigated with XRD analysis, Field Emission- Scanning Electron Microscopy, and Vi...

The spinel Ni-ferrite with different synthesizing temperature was synthesized by the glycine-nitrate auto-combustion process. X-ray diffraction, field emission-scanning electron microscopy, Fourier transform-infrared spectroscopy and Photoluminescence analysis were used to characterize structural, morphological and optical properties of the as-synt...

Mixed spinel Mg1-xZnxFe2O4 ferrites (where x = 0, 0.2, 0.4, and 0.6) nanoparticles were synthesized by using microwave-assisted combustion route. As-synthesized powdered samples were checked by XRD analysis, field emission-scanning electron microscopy, and vibration sample magnetometer to investigate the structural, morphology, and magnetic propert...

We report the influence of different glycine-to-nitrate ratios on the physical and magnetic properties for synthesized zinc-ferrite by microwave-assisted combustion route. Phase impurity and surface morphology investigated with XRD analysis and field emission- scanning electron microscopy, indicated that spinel structure were formed.Average particl...

Three samples of spinel powdered zinc ferrites were successfully fabricated via microwave-assisted combustion method followed by calcination at temperature of 500oC for three hours. Phase purity and surface morphology that estimated via XRD pattern and field emission-scanning electron microscopy images (FE-SEM) showed that the samples have cubic sp...

As a result of intense daily use of building material by people, in this search the natural radiation of samples were measured (block, brick, gypsum, thermo stone, cement and plaster). The detection and measurement system are made up of a nuclear detector was used, . The radioactive sources (137Cs, 22Na, 60Co) were used detector The results showed...

Lead Sulfide (PbS) thin films were prepared by spraying pytolysis Method (SPM). Glass substrates with (1 x 2.6 x 7.6) cm were used at room temperature . Thin film of (PbS) was a doped by (Copper ,Cu) then the effect of annealing at different temperatures(100,200)C0 on the optical properties of (pbS) and (PbS:Cu) are investigation. The optical prop...
