Aluminium-Doped Zinc Ferrite Nanoparticles Synthesized by Combustion Method for Polymer Composite Applications
Abstract: ZnFe₂₋xAlₓO₄ (x = 0 and 0.5) nanoparticles were synthesized via a combustion method owing to its simplicity, cost efficiency, and ability to produce highly crystalline nanomaterials. Powder X-ray diffraction (XRD) analysis confirmed the formation of a single-phase cubic spinel structure without detectable secondary phases, indicating high phase purity. The average crystallite size was estimated to be in the range of 14–20 nm, confirming the nanocrystalline nature of the samples. Field-emission …

Comparative Study of Structural and Optical Properties of Bismuth Ferrite Nanoparticles for Photovoltaic Applications Synthesized via Different Sol-Gel Methods
Abstract: Pure multiferroic bismuth ferrite (BiFeO3) nanoparticles were successfully synthesized using an energy-efficient, low-temperature sol-gel method, comparing two distinct approaches: auto-combustion and non-auto-combustion. To ensure phase stability, the precursor solution's pH was strictly maintained between 1 and 2 using ammonia solution (NH4OH), while ethylene glycol (C2H6O2) was employed as a chelating agent for the Fe3+ and Bi3+ cations. All samples underwent a final annealing process at 500 °C to promote crystallization. …
