Synthesized and characterized nanostructured ferrites (Ni-Zn, Mn-Zn, Li-Zn-Ti-Mn) with particle sizes 8–47 nm and high crystallinity. Applied XRD, SEM/EDX, FTIR, AAS, TGA/DTA to verify phase purity and composition. Developed ceramics and polymer-ferrite composites for microwave shielding and investigated their magnetic, dielectric, photocatalytic, and antimicrobial properties. Co-authored 6 publications and co-invented 2 patents on scalable ferrite synthesis.

Provided personalized online tutoring in advanced chemistry for high school students, covering curriculum-aligned theoretical concepts and practical problem-solving strategies. Successfully prepared students for final and university entrance exams, with multiple students achieving top-tier results through tailored academic support.

Developed and prepared chemical formulations for public science shows, including kinetic and photophysical experiments like Briggs–Rauscher, nitrocellulose combustion, and flame color reactions. Advised 15 staff on chemical safety and experimental formats. Introduced three new demonstrations, including thymolphthalein-based pH visualization. Translated complex chemistry into engaging content for broad audiences. Managed reagent procurement, storage, and lab safety protocols.

Produced a 3 kg batch of lithium-zinc-titanium ferrites via stoichiometric formulation, dual-stage milling (Bi₂O₃/PVA), and ferritization at 850 °C, yielding structurally homogeneous ceramics with improved magnetic properties. Performed product attestation through granulometry and ring testing, confirming performance within 0.3% deviation. Supervised the full production cycle, optimized process conditions with engineers, and maintained technical documentation for quality control.
