ZrO2 nanopowder was prepared by the sol-gel auto-combustion method. The product was characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). The average crystalline size of ZrO2 was obtained 62 nm. Also, photocatalytic removal of nitrophenol from aqueous solution by using nanoscale ZrO2 under UV ...

In this research nano particles of bismuth ferrite (BiFeO3) were synthesized by sol-gel auto-combustion route. The effect of water and ethylene glycol solvents were studied on phase constituents, magnetic properties and microstructure of the bismuth ferrite by X-ray diffraction (XRD), scanning electron microscope (SEM) and vibration sample magnetometer (VSM) techniques. XRD resul...

In this paper, BaLa‌xGdxFe12-2xO19 (x=0.2, 0.4, 0.6 and 0.8) were synthesized via sol-gel auto-combustion method. Fourier transform infrared spectroscopy (FTIR) of samples was represented that the bands at 400 and 500 cm-1 were related to the formation of hexaferrite phase. The (x-ray diffraction) XRD patterns were matched exactly with the structure of barium hexaferrite. (Field emission scanni...

The medical application of injection of monoclonal antibodies using a controllable auto-loading needle-free jet injector has been evaluated for two potentially limiting factors: viscosity of the formulation and shearing of the antibody during ejection. We used the Hepatitis B monoclonal antibody C86322M for its easy access and widespread usage. We used repeatability studies of glycerol at up to...

This work focuses on the microstructure, magnetic properties and magnetocaloric effect of CoFe$_2$O$_4$ (CFO) nanoparticles elaborated by sol-gel auto combustion method. The XRD investigation indicates that CFO is crystallized in a cubic spinel structure SEM micrograph shows fine quasi-spherical with an average grain sizes 160 nm. temperature dependence Raman spectra reveals ferromagnetic to pa...

Nanocrystalline Li0.35Ni0.3Fe2.35O4 ferrites were prepared at different annealing temperatures by sol–gel auto-combustion method. The effects of the temperature on structure and magnetic properties synthesized Li–Ni characterized X-ray diffraction (XRD), scanning electron microscopy, Fourier transform infrared spectra Vibrating Sample Magnetometer, photoelectron spectrometer. Rietveld refinemen...
