Nanosize Iron Oxide for CO Oxidation

Wu Z., Fransson M., Zhou B., Headwaters Technology Innovations LLC, US

Transition metal oxides are desirable alternatives to precious metals based catalysts for CO oxidation since they are less costly. Several nanosize iron oxides were prepared by using Headwaters Technology Innovation (HTI) NxCat® colloidal chemistry nanotechnology. [...]

An integrated NMR/nanosensor system for sensitive detection of environmental toxins and harmful microbes

Perez J.M., Fries D.P., Hickman J.J., University of Central Florida, US

The use of nanoparticles and NMR detection technologies has lead to significant improvements in sensitivity. Nanoparticles have many useful optical and electronic properties derived from their small size. When coupled to affinity ligands, these materials [...]

Nanoscale Maghemite Iron Oxide Powders Prepared by Laser Pyrolysis

Morjan I., Dumitrache F., Alexandrescu R., Birjega R., Voicu I., Gavrila L., Soare I., Filotti G., Kuncser V., Ciupina V., National Institute for Lasers, Plasma and Radiation Physics, RO

Nano-sized maghemite particles (usually less than 15 nm diameter) have been directly synthesized by the laser induced pyrolysis of iron pentacarbonyl vapors. Ethylene was used as sensitizer of the induced reaction. By the controlled use [...]

A search of superparamagnetic iron oxide-myoglobin as potential nanoparticle based magnetic resonance imaging marker in mouse heart imaging

Sharma R., Haik Y., Chen C-J., FAMU-FSU College of Engineering, US

Superparamagnetic iron oxide (Fe2O3) has emerged as potential MRI contrast agent in whole animal imaging to localize the site of clinically important physiological damage such as ischemia, angiogenesis, oxygen insufficiency, immuno-deficiency [1, 2]. We achieved [...]
