TL;DR: Pure and cobalt doped zinc ferrites were prepared by microwave combustion method using L-arginine as a fuel and a gradual increase in the coercivity and saturation magnetization (M(s)) were noted at relatively higher cobalt doping fractions.

TL;DR: In this article, the effects of Ba 2+ doping on structural, optical, magnetic and catalytic activity of La 2 CuO 4 nanoparticles have been studied by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance spectrograph (DRS), scanning electron microscopy (SEM), and energy dispersive X-rays analysis (EDX) and vibrating sample magnetometer (VSM) techniques.

TL;DR: In this paper, the optical properties of ZSAC composites were investigated using UV-Vis diffuse reflectance spectrograms and photoluminescence spectrographs, which exposed prolonged light absorption in UV light region and hold better charge separation capability than pure ZnO.

TL;DR: The structural, morphological and magnetic properties of Ni-doped ZnFe2O4 nanoparticles were determined by X-ray diffraction (XRD), high resolution scanning electron microscopy (HR-SEM) and vibrating sample magnetometer (VSM) as discussed by the authors.

TL;DR: In this paper, a set of strontium-II-added ZnAl2O4 composites were analyzed by X-ray diffraction, scanning electron microscopy (SEM) and nitrogen adsorption/desorption isotherms at 77 K and studied for humidity sensing characteristics.
