Enhanced Magneto-Optic Properties Using Polymer-Coated Magnetite Nanoparticles
Researchers at The University of Arizona's James C. Wyant College of Optical Sciences have developed a two-step process for creating Magneto-optical (MO) nanocomposites. First it forms a polymer shell on magnetite-nanoparticles though a surface polymerization process. It then chemically links the shell of each magnetite-nanoparticle to a host polymer...

Alkali Metal Doped Graphene as Solid Hydrogen Storage System
University of Arizona researchers have developed an alkali metal ion doped graphene that is used as a material for a hydrogen storage system. Background: The majority of currently commercially available materials used for storage systems are metal. Using metal causes the system to be heavy and have a low gravimetric density. Other materials require...

Fullerene Assemblies with Tunable Shapes and Electrical and Ionic Conductivity for use as Battery Electrolytes and Other Applications
This technology is a self-assembling manufacturing process for post manufacture fullerene processing. This method is used to control the shape (rods or flower/fractal) and conductivity. Such materials can be used solid-state electrolytes and components of electrodes and can be doped with alkali metals and has the potential to replace Li diffusion film...

Metal Electrodes and Active Polymer Layers for Solar Cells
Researchers at the University of Arizona have developed a method for creating nanostructured electrodes that is cost effective and that also gives patterns that possess excellent uniformity. The patterns consist of conductive nano-columns that have controllable diameters and spacings. This fabrication control allows the electrodes to be tuned to possess...
