Doping of Nano Cobalt Ferrites by Cupper: Structural and Magnetic Properties Studies
A series of Cupper-substituted cobalt nano ferrites (CuxCo1-x Fe2O4 with = 0.00, 0.10, 0.20, 0.30 and 0.4) was synthesized via hydrothermal method. The structural characterizations of all the prepared nanoparticles were performed using powder x-ray diffraction, EDAX and FTIR analyses. These studies confirmed the formation of single-phase spinel structure in at lower compositions. The increase in the value of lattice ... إقراء المزيد

Effect of the synthesis conditions on the structural, morphological and optical properties of Bi2Te2.7Se3 nanoparticles
Beside their promising utility as thermoelectric generators, Bi2Te3 and related compounds have several applications in electronic and optoelectronic devices. In this work, Bi2Te2.7Se0.3 nanoparticles (NPs) were successfully prepared via physical vapor deposition technique at different conditions of flow rate and temperature. The x-ray diffraction patterns show that, the NPs crystallize in a rhombohedral crystal structure with preferable growth along the ... إقراء المزيد
