Biosynthesis and magnetic properties of mesoporous Fe3O4 composites

Fe3O4/PS magnetic nanoparticles: Synthesis, characterization and their application as sorbents of oil from waste water

“…There are numerous magnetic materials, in which the Fe 3 O 4 is of great interest due to its non-toxic characteristic, low cost and strong magnetic response. At present, there are many methods for the synthesis of Fe 3 O 4 such as co-precipitation method [28][29], solution casting technique [30], template method [31] and so on [32]. In this work, we reported a kind of recyclable, environmentally friendly and highly selective oil-absorbent materials based on core-shell structure for removing oils from water surface.…”

Synthesis and characterization of l-carnosine coated iron oxide nanoparticles

“…Among these, superparamagnetic iron oxide nanoparticles (SPION) receive increasing attention in different fields of physics, medicine, biology, and materials science due to their multifunctional magnetic, catalytic, biological and conducting properties which make them feasible to find applications in various fields [1]. In clinical area, these particles are used as delivery systems for drugs [2], in medical diagnosis [3][4][5], hyperthermia [6][7][8], cell separation [9,10], etc. Most of these applications require well-dispersed chemically stable nanoparticles having uniform size and shape.…”

Direct synthesis and characterization of mesoporous Fe3O4 through pyrolysis of ferric nitrate-ethylene glycol gel

“…Huang and Tang demonstrated the synthesis of mesoporous Fe 3 O 4 hollow spheres using hydrothermal synthesis using carboxyl-functionalized PS spheres as the templates and ethylene glycol (EG) as an organic structure directing agent and then removing PS and EG by calcinations [19]. He and co-workers reported the synthesis of mesoporous Fe 3 O 4 by coprecipitation method using yeast cells as a template [20]. Xia et al reported the synthesis mesoporous Fe 3 O 4 clusters by selfassembly of a cyclodextrin-polymer surfactant (CD-polymer) complex under one-pot reaction in an aqueous medium [21].…”
