Characterization files for the analysis of Mg-Zn nanoferrites flavonoids

<p>Nanosized ferrites Mg<em>_x</em>Zn_1-<em>x</em>Fe₂O₄ (0 &lt; <em>x </em>&lt;1) was effectively synthesized using a wet ferritization method. The obtained spinel nanoparticles were then treated with flavonoids (Flv) extracted from agricultural waste of <em>Punica granatum</em> L. and <em>Allium cepa </em>L. Various characterization techniques such as FTIR, XRD, DTA-TGA, VSM, FE-SEM, TEM, EDX, and BET were utilized to analyze the surface morphology, magnetic properties, and elemental composition. The X-ray diffractograms revealed that the synthesized Mg<em>_x</em>Zn_1-<em>x</em>Fe₂O₄ (MZFO) nanoparticles displayed a uniform cubic spinel structure, indicating the presence of a single phase. Morphological analysis revealed two distinct categories of MZFO nanoparticles: flower-shaped and plate-shaped particles. The attendance of Mg, Zn, O, Fe, and C elements in both MZFO and Flv/MZFO samples was confirmed by EDX analysis. TEM analysis further confirmed that each particle of the modified MZFO sample was a single crystal with an average particle size of 22 nm. Additionally, the modified MZFO nanoparticles exhibited a weight loss of 39.17% due to surface modification. Notably, the modified MZFO nanoparticles displayed remarkable superparamagnetic behavior with a saturation magnetization of up to 41.875 emu.g^-1. BET analysis demonstrated that the Flv/MZFO nanoparticles possessed a mesoporous structure with a total pore volume of 0.1349 cm³/g, an average pore size of 17.044 nm, and a specific surface area of 31.655 m²/g. The conjugated Flv/MZFO nanoferrites exhibited significant antibacterial efficacy, with inhibition zones of 7 mm and 8 mm against Gram-positive and Gram-negative bacteria, respectively. </p>
