A series of virgin and lithia-doped Ni ferrites was synthesized using egg-white-mediated combustion. Characterization the investigated performed several techniques, specifically, X-ray Powder Diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), High-resolution transmission electron microscopy (HRTEM). XRD-based structural parameters were determined. closer look at these characteri...

organic solvents. In this study, NiFe2O4/sawdust nanocomposite was synthesized for removingoil pollutants. The oil-adsorbing nanocomposite could be easily separated from water bymagnet bar. The XRD results show tetragonal phase proving the composite formation. TheFESEM pictures successfully reveal the growth of NiFe2O4 on the sawdust template. The FTIRbands at 422 cm-1 and 615 cm-1correspond to...

The effects of temperature, time and atmosphere on microstructure and magnetic properties of NiFe2O4 glassceramic were investigated utilizing differential thermal analysis, X-ray diffraction, vibrating sample magnetometer and scanning electron microscope techniques. Various compositions were studied in the Na2O-NiO-Fe2O3-B2O3-SiO2 system to obtain amorphous phase. The sample heat-treated in gr...

The antimicrobial resistance currently impedes and threatens the future of effective prevention treatment continually expanding range infections caused by bacteria. This study aimed to identify bacterial causes wound infection among animals using antibiotic/nanoparticles mixture as a new attempt for induced in rats. For this purpose, 112 swabs cases different animal types (36 sheep, 21 goats, 1...
