“…The X-ray density [13] has been calculated using the relation The calculated values of lattice parameter (a), crystallite size (D), X-ray density (ρ x ) and lattice strain (η) are summarized in Table. [16] and it was observed that the lattice parameter increases monotonically with the substitution of Mg 2+ , which is attributed to smaller ionic radius of Mg 2+ (0.67Å) compared to Zn 2+ (0.74Å). The similar observations were reported for other spinel ferrites [17,18].…”

Abstract:MgFe 2 O 4 ferrite has excellent magnetic behavior and high resistive material. The properties of Mg ferrite were investigated by solid state reaction method. In this work, our aim is to synthesize MgFe 2 O 4 using oxide precursors (i.e. MgO and Fe 2 O 3 ). The samples were pre-calcined at 800 o C for 5 hours and calcined at 1000 o C for 6 hours and have the single phase cubic spinel structure. The phase composition, micro-morphology, elemental analysis and Wyckoff sites of the products of Mg-Fe-O system were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared (FTIR), respectively. Spinel Mg ferrite belongs to Fd-3m space group. From the XRD result the crystallite size, lattice constant and cell volume of MgFe 2 O 4 was found to be 44.94 nm, 8.426Å and 598, respectively. From SEM result the magnesium ferrite particle size formed was ranged from 251 nm to 414 nm in diameter for the given alcinations temperature at 1000 °C. The EDS spectra confirm the presence of Fe, Mg and O in the compound. In FT-IR analysis vibrations of ions in the crystal lattice of Mg ferrite observed in the range of 1200-400 cm -1 and the high-frequency band (ν 1 ) lies in the 650-530 cm -1 range and the low-frequency band (ν 2 ) in the 446-400 cm -1 range.

“…Furthermore, size was calculated using Scherrer's formula, D = kλ/βcos θ, where λ is the wavelength, β is the corrected diffraction line full-width at half-maximum, k is a constant (having value 0.94) and θ is Bragg's angle. [47] The average diameter of the MCS-GT@Co(II) nanoparticles has been calculated and found to be 20.04 nm. The particle size of MCS-GT@Co(II) nanoparticles was also determined via TEM imaging (Figure 3).…”

A simple, highly efficient and green synthesis of 2,4,5-trisubsituted and 1,2,4,5-tetrasubstituted imidazoles was developed using a novel MCS-GT@Co(II) magnetically recoverable and recyclable catalyst under refluxing conditions with ethanol as a solvent. The catalyst was prepared by immobilization of chitosan onto Fe 3 O 4 using glutaraldehyde as crosslinker followed by Co(II) ion immobilization via cobalt acetate. The catalyst was characterized using various techniques. For organic products determination, 1 H NMR, 13 C NMR and Fourier transform infrared spectroscopies were used. The reaction was also tried with individual components of the catalyst, but the synergistic effect of the components in the prepared catalyst showed the highest yield and shortest reaction time.
