Microstructural Statistics in Solid Oxide Fuel Cell Electrodes

Electrical Detection of Spin Transport in Semiconductors

In semiconductor spintronics, the spin of the electron carries information for both storage and data processing. To some extent, the electron spin can be viewed as a miniature bar magnet that interacts with a magnetic field inside the semiconductor. The orientation of the bar magnet acts as a "bit" of information.

Ion Gel-Gated Polymer Thin Film Transistors

A major goal of organic electronics is the development of new kinds of solution processable organic dielectric materials that can serve as gate insulators in organic thin film transistors (OTFTs).

Materials Stiffer Than Diamond

For hardness and stiffness, it's long been thought that nothing beats diamond. But Roderic Lakes and Don Stone, from the University of Wisconsin MRSEC and their colleagues have made a material that is almost ten times stiffer, by embedding small particles of barium titanate in a matrix of tin.
