AlX.YB2O3 [(6-X-Y)P2O5]. TeO3 (X = 3, 2, 1, and Y = 2.5, 1.5, and 0.5) were sintered for 2 hours at 800°C using the sol-gel method. The ultraviolet-visible study shows maximum absorbance at 264 nm with optical band gap energy range of 4.21 to 4.24 eV. The X-ray diffraction pattern confirmed the arrangement of the FCC structure with an average crystallite size of 21.63–25.77 nm. The morphological structure was investigated using field emission scanning electron microscopy (FE-SEM), and their size was confirmed by high resolution transmission electron microscopy (HR-TEM).The energy-dispersive X-ray spectroscopy (EDS), which validated the TeO3 composition. The highly magnetic character was estimated using the Vibrating Sample Magnetometer (VSM) technique. It is extensively used as a conducting material because of its low dielectric loss. The glass material shows the application towards the various antimicrobial activities.

Nickel and Samarium-doped strontium ferrite nanoparticles were synthesised using the sol-gel auto-combustion method. The micro-structural characteristics of the ferrite were investigated using X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The particle size was determined to be between 30 and 60 nm. The vibrating sample magnetometer (VSM) revealed a strong magnetization with paramagnetic behaviour, and the existence of all elements was verified by energy dispersive X-ray spectroscopy (EDS). According to the BET adsorption isotherm, total surface area ranges from 13.77 m2g-1 to 28.49 m2g-1. At P/Po (0.99), the total pore volume ranges from 0.02 cm3g-1 to 0.04 cm3g-1. The average pore width ranged from 3.5 nm to 6.5 nm, and the isotherm demonstrates type III with an H3 hysteresis loop. The material shows 84% thermal stability and these synthesized nanoparticles are showing activity against both Gram Positive and Gram-Negative bacterial pathogens.

A novel, well‐designed, silica‐supported magnesium ferrite nanorods were successfully developed at room temperature using the co‐precipitation method. The synthesized nanorods show an optical band gap of 3.1 eV, with the maximum wavelength absorptive at 334 nm. The average particle size is 36 nm with the FCC crystal structure by the X‐ray Diffraction technique (XRD). TGA achieved thermal stability of targeted mesoporous materials at 600°C. Field Emission Scanning Electron Microscopy (FE‐SEM) and High‐Resolution Transmission Electron Microscopy (HR‐TEM) techniques confirm the rod‐like structure. Energy Dispersive Spectroscopy (EDS) and X‐Ray Fluorescence (XRF) studies reveal the presence of all elements in the composition. The synthesized nanorods are highly magnetic by the vibrating sample magnetometer (VSM) technique, which shows a high coercivity value, that is, MgFe2O4@SiO2 is photocatalytically active. From BET analysis, the surface area, pore volume, and pore diameter are 19.2 m2 g−1, 2.46 cm3 g−1, and 5.10 nm, respectively. The experimental outcomes predict that the degradation efficiency (79%) of methyl orange dye was accomplished using MgFe2O4SiO2 nanorods within 270 min.
