Core Shell Structure

The magnetite (Fe3O4) nanoparticles were prepared by coprecipitation of Fe3+ and Fe2+ with aqueous NaOH solution. The Fe3O4/polyaniline (PANI) magnetic composite nanoparticles with core-shell structure with diameter of 30-50 nm were prepared via an in-situ polymerization of aniline in aqueous solution containing Fe3O4 magnetic fluid. The inductive heat property of Fe3O4/polyaniline composite nanoparticles in an alternating current (AC) magnetic field was investigated. The potential of Fe3O4/polyaniline nanoparticles was evaluated for localized hyperthermia treatment of cancers. The saturation magnetization Ms and coercivity Hc of Fe3O4 nanoparticles are 50.05 emu/g and 137 Oe respectively, the Fe3O4/polyaniline composite nanoparticles, 26.34 emu/g and 0 Oe. Exposed in the alternating current (AC) magnetic field for 29 min, the temperatures of physiological saline suspension containing Fe3O4 nanoparticles or Fe3O4/polyaniline composite nanoparticles are 63.6 °C and 52.4 °C respectively. The Fe3O4/polyaniline composite nanoparticles would be useful as good thermoseeds for localized hyperthermia treatment of cancers.

Core Shell Structure

CMP is commonly recognized to be the most effective technique of achieving global planarization. SiO2 and CeO2 abrasives are the most commonly used in CMP slurries due to their good polish performance. To consider respectiveSubscript text advantages and synergistic effect, preparation of SiO2/CeO2 composite nanoparticles with core/shell structure have become a hot topic in CMP field. We introduced the preparation technology of SiO2/CeO2 and their applications in CMP in recent years.
