Rapid development of electronic devices and advanced technology creates more electromagnetic wave interference that is harmful to human health as well equipment. Thus, the use (EM) absorber becomes focused among researchers attracted public attention. Carbon nanocoils (CNs) have been introduced due its chemical, physical mechanical properties can produce lightweight, wide absorption range stron...

Green synthesis of nanoparticles makes use of environmental friendly, non-toxic and safe reagents. In this study, we synthesised CoFe2O4 in a green approach, using leaf extract of Chenopodium album. The structure of the synthesised sample were analyzed by X-ray diffraction methods. The synthesised Photocatalyst was applied for photo degradation of methy orange as a reliable model pollutant. The...

CoFe2O4 have been synthesized via a surfactant assisted gel microwave route with a molar ratio of Fe/Co= 2 and oleic acid (OA) was used as a surfactant. Fourier Transform Infrared spectroscopy (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to consider the structural and morphological properties of CoFe2O4 nano-particles. Results demonstrated that oleic acid is ...

Hierarchical copper shells anchored on magnetic nanoparticles were designed and fabricated to selectively deplete hemoglobin from human blood by immobilized metal affinity chromatography. Briefly, CoFe2O4 nanoparticles coated with polyacrylic acid were first synthesized by a one-pot solvothermal method. Hierarchical copper shells were then deposited by immobilizing Cu2+ on nanoparticles and sub...

Single phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation followed mechanochemical treatment, microemulsion and microwave hydrothermal synthesis. The CoFe2O4 samples have been studied using a variety characterization techniques: X-ray diffraction (XRD), Raman spectr...

This paper investigates the mixed convection flow related to Fe3O4-CoFe2O4/water hybrid ferrofluids on stagnation point over an exponentially stretching/shrinking surface with influence of magnetohydrodynamic (MHD), velocity slip, and heat source/sink. The proposed system differential equations is reduced using similarity transformation procedure that numerically solvable MATLAB. Dual solutions...
