Nanotechnology is becoming a revolutionary field with important applications in both industry and research. However, there is a significant disconnect between academic laboratory training and the technical skills needed by business. The current study emphasizes the sol-gel auto-combustion method's application as a useful skill development model in higher education while concentrating on the production of zinc nanoparticles. Standard analytical methods like Brunauer-Emmett-Teller (BET) surface area analysis, Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD) were used to create and characterize zinc nanoparticles. The development of high-surface-area nanoscale crystalline particles was validated by the findings. This study focuses on developing students' laboratory abilities, analytical proficiency, data interpretation skills, and training in research technique in addition to material synthesis. Nickel–Magnesium–Copper Zinc Ferrite nanoparticles with the general formula 〖Ni〗_ (0. 65-2X) 〖Mg〗ₓ 〖Cu〗ₓ 〖Zn〗_ (0. 35) 〖Fe〗₂ O₄ (For x= 0. 1, x = 0. 2, x = 0. 3) were synthesized using the sol–gel auto-combustion technique. The sol–gel auto-combustion method is a cost-effective, low-temperature, and efficient technique for preparing homogeneous nanosized ferrite powders with controlled stoichiometry. Analytical grade metal nitrates were used as precursors and citric acid as a chelating agent and fuel. The pH of the solution was adjusted to ~7 using ammonia solution. The resulting gel underwent spontaneous combustion to form fine ferrite powders, which were subsequently calcined at 400–600°C to improve crystallinity. The structural properties were investigated using X-ray diffraction (XRD), XRD analysis confirmed the formation of a single-phase cubic spinel structure. The average crystallite size calculated using the Scherrer equation ranged from 20–45 nm. The synthesized ferrites exhibit promising properties for applications in electromagnetic devices, microwave absorption, and magnetic storage.
