KEY ACHIEVMENTS

1.       Successfully established a strong research group on nanostructured magnetic materials. Developed an advanced research direction in transition-metal-based nanostructured magnetic materials, significantly increasing both the quantity and quality of high-impact international publications. Core members authored 17 SCIE papers (13 in Q1 journals, IF = 3.5–6.7, with 8 papers IF > 5) and contributed to many other SCIE articles during 2022–2024.

2.       Successfully synthesized and studied the properties, photocatalytic activity, and magnetocaloric effects of ferrofluids and core–shell magnetic nanoparticles.

3.       Successfully fabricated and investigated multilayer magnetoresistive films, demonstrating room-temperature magnetoresistance effects and potential applications in magnetic recording, spin valves, and spintronics.

4.       Developed a novel magnetic nanoparticle system based on porous SiO₂ integrated with GdₓFe₃₋ₓO₄ for targeted drug delivery in cancer treatment.

5.       Successfully synthesized and studied the properties of nanowires and single-component nanoparticles for applications in biosensors.
