Characterization files for the analysis of Mg-Zn nanoferrites flavonoids

Nanosized ferrites MgxZn1-xFe2O4 (0 < x <1) was effectively
synthesized using a wet ferritization method. The obtained spinel
nanoparticles were then treated with flavonoids (Flv) extracted from
agricultural waste of Punica granatum L. and Allium cepa 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 MgxZn1-xFe2O4 (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.
