Hierarchical structure and magnetic behavior of Zn-doped magnetite aqueous ferrofluids prepared from natural sand for antibacterial agents

This study performs natural sand-based synthesis using the sonochemical route for preparing Zn-doped magnetite nanoparticles. The nanoparticles were dispersed in water as a carrier liquid to form Zn-doped magnetite aqueous ferrofluids. Structural data analysis indicated that the Zn-doped magnetite n...
