Tiny Tubes Trumpet New Possibilities

摘要

Nanotechnology may soon provide warfighters with lightweight and powerful electronic equipment. Researchers have created a fully functional transistor radio made entirely of carbon nanotubes. This feat demonstrates that these microscopic structures can be used as high-speed transistors and radio system components that consume only a fraction of the power required by current equipment.rnThe radio was designed and built by a team of scientists from Northrop Grumman Corporation and the University of Illinois at Urbana-Champaign to highlight the technology's capabilities. Carbon nanotubes are among the most promising developments in nanotech-nology, explains Dr. John Przybysz, a senior consulting engineer at Northrop Grumman, Baltimore.
