Current study represents the effect of the size and synthesis method on the cation distribution of cobalt ferrite nanoparticles and on the magnetic properties. The nanoferrites have been synthesized through sol-gel auto-combustion method using metal nitrates as precursor and citrate as fuel. In order to obtain the fine and agglomerated-free particles, we have used salt-assisted combustion react...

In this study, three samples of GaN/AlInN/AlN/Al2O3 high electron mobility (HEMT) structures are investigated with resolution X-ray diffraction (HR-XRD) technique. Peak positions and peak broadenings used in calculations, gained from rocking curves. Structural quality is determined symmetric asymmetric planes. Mosaic defects such as treadening dilocations (TDs), tilt twist angles, lateral verti...

Storage of hydrogen is one of the key challenges in developing hydrogen economy. Magnesium hydride (MgH2) is an attractive candidate for solid-state hydrogen storage for on-board applications. In this study, 10 wt.% ZrB2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. The effect of milling time and additive on the hydrogen desorption...

In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...

The La modified bismuth ferrite perovskite Bi0.6La0.4FeO3 (BLF) is prepared by cost-effective high solid-solution casting technique. Formation of composite checked through X-ray diffraction and also notable that there phase transition from rhombohedral (R3c) to orthorhombic (Pbnm). average crystalline size (DSC) mechanical lattice strain are 63.8 nm 0.147% respectively as calculated Williamson-...

In this article, some Fe (III) doped hydroxyapatite samples (FeHAp) were prepared using the wet chemical method. The prepared samples were characterized via the use of X-ray diffraction (XRD) and scanning electron microscopy (SEM). Detailed structural analysis were done by Scherrer and Williamson–Hall plot methods to detect the effect of iron on the structure of hydroxyapatite (HAp). XRD patter...

In this modern era, most of the equipment is electrostatic type. But still, in measuring current, we use conservative type. So, we developed a Modified coreless Hall Effect based current sensing method with magnetic shielding. The coreless Hall Effect based measurement method uses hall sensors without iron core. Hall sensors are firmly fixed on the insulated current carrying conductor. The magn...
