Thermodynamic Determination of the Cation Distribution in NixMn1-Î3-xFe2+Î3O4 Ferrites

Structural and mechanical properties of AFe2O4 (A = Zn, Cu0.5Zn0.5, Ni0.3Cu0.2Zn0.5) nanoparticles prepared by citrate method at low temperature

In this work, the structural and elastic moduli properties of ZnFe2O4, Zn0.5Cu0.5Fe2O4, and Ni0.3Cu0.2Zn0.5Fe2O4 ferrites prepared by the citrate method have been investigated. The structuralcharacterization of the samples is evidence for a cubic structure with Fd-3m space group. TheHalder-Wagner analysis was used to study crystallite sizes and lattice strain and also stressand energy density. ...

Solvent Effect on Stability and Thermodynamic Behavior of Complex of 18-Crown-6 with Hydroxyl Ammonium Cation

The complexation reaction between hydroxyl ammonium (HONH3+ ) cation with 18-crown-6 (18C6) ligand was studied in dimethylsulfoxide – water (DMSO-H2O), methanol – water (MeOH-H2O) and dimethylformamid – methanol (DMF-MeOH), binary solutions at different temperatures using conductometric method. The obtained results show that the stoichiometry of t...

Preparation and Characterization of Nickel and Copper Ferrite Nanoparticles by Sol-Gel Auto-Combustion Method

Ferrites with spinel structure are the most widespread materials in radio engineering, electronics and communication industry, microwave devices and computer facilities. The change of synthesis temperature of ferrites results in cation redistribution of iron, which updates crystal properties, as macroscopic magnetic properties of ferrites. Among this extensive class of compounds nickel and copp...

An Iridatropylium Cation: Investigation of Electronic Structure

A study of the [C6 H6 Ir(PH3 )3 ]+ iridatropylium cation structure based on frontier orbital analysis, thermodynamic analysis, and natural bond orbital (NBO) theory is the main aim of the present research. Also, HOMO, LUMO energies, hardness, electrophilicity and chemical potential were calculated. Structural analysis indicated the optimized geometry shows a good agreement with the experimental...
