Nanocomposites: Chemical Force Microscopy Helps Choose Right Materials for Future Composites Based on Nanotubes
A microscopy technique originally developed to image the molecular-scale topography of surfaces is now helping engineers choose the right materials for a new generation of lightweight high-strength composites based on carbon nanotubes.
Light, conductive and nearly as strong as steel, carbon nanotubes are being combined with lightweight polymers to produce composite materials with properties attractive for use on future space vehicles. But choosing the right polymer for optimal mechanical performance at the nanometer scale requires a lengthy trial-and-error process.

OSU engineers create world's first transparent transistor

Engineers at Oregon State University have created the world's first transparent transistor, a see-through electronics component that could open the door to many new products. The advance has been reported in a professional journal, Applied Physics Letters, and a patent has been applied for. The university is already consulting with major electronics companies about the findings and their potential applications. The discovery "is a significant development in the context of transparent electronics," the scientists said in their publication, but added that it's too early to tell what applications may evolve.

New Measurements Show Silicon Nanospheres Rank Among Hardest Known Materials

University of Minnesota researchers have made the first-ever hardness measurements on individual silicon nanospheres and shown that the nanospheres' hardness falls between the conventional hardness of sapphire and diamond, which are among the hardest known materials. Being able to measure such nanoparticle properties may eventually help scientists design low-cost superhard materials from these nanoscale building blocks.

UCSD researchers develop flexible, biocompatible polymers with optical properties of hard crystalline sensors

Researchers at the University of California, San Diego have discovered how to transfer the optical properties of silicon crystal sensors to plastic, an achievement that could lead to the development of flexible, implantable devices capable of monitoring the delivery of drugs within the body, the strains on a weak joint or even the healing of a suture.
