Anwendung

This material is highly monodisperse in size and shape (<0.25 polydispersity index), and provides significantly improved surface reactivity. It is stable at high suspension densities, when utilized at the recommended pH range (3.0-4.0). Applications include emissions catalysis, oxidation catalysis, regeneration of particle traps in diesel engines, and use as a pigment.

Professor Hui Mao explores the use of superparamagnetic iron oxide nanoparticles (INOPs) that offer an alternate contrast-enhancing mechanism.

Electronically, it behaves as a wide band gap (3.2 eV) semiconductor and exhibits memristor properties.2 Optically, TiO2 has high opacity with a very high refractive index3 (>2.4), and it exhibits strong absorbance in the UV range.

Professor Yadong Yin (University of California Riverside, USA) examines both direct (thermal decomposition, solvothermal, hydrothermal) and indirect (templated) synthesis methods of magnetite nanocrystals and reviews in detail the landscape of these various synthetic methods for magnetite nanocrystal and their applications in magnetic assembly, magnetic hyperthermia, and Li-Ion batteries.

Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door, electric bicycles that speed our commute to work, as well as wind turbines for conversion of wind energy to electrical power.
