Recent Developments in Magnetic Iron Oxide Nanoparticles for Non-Invasive Bioimaging

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

Titania Nanotubes: Synthesis and Applications

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.

Synthesis and Application of Shape-Controlled Fe3O4 Nanostructure

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.

Soft Magnetic Nanocrystalline Alloys: Materials and Models

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
