Japan'S AIST Develops Ultra Low-Power Carbon Nanotube Field
: The National Institute of Advanced Industrial Science and Technology (AIST) has developed a carbon nanotube field emitter, and succeeded in discharging electrons by applying 4V, 1/10 to 1/100 the level of conventional silicon or metal-based field emitters. .. pav[ing] the way to use field emitters for low-power flat panel displays including mobile device displays" 10:21:24 PM
: MIT's BioInstrumentation Laboratory is building an fleet of thumb-sized robots that will be able to measure and assemble structures at a molecular level. "Nanowalkers" have been able to take 4,000 nanoscale steps per second—that is, steps that are only a few billionths of a meter each. They envision one hundred or more robots deployed on a project, each equipped with a different instrument, working on separate but related tasks: While one NanoWalker tests a material's strength, another would measure its optical properties. Both would transmit their results to the central computer, which would incorporate the information and then issue new directions. 12:19:23 PM
Nanocoating protects materials, making 'nanosteel'
: "A composite material, made up of steel alloy clumps with only a few molecules per particle, could turn inexpensive, ordinary metals into durable building materials, researchers at the Idaho National Energy and Environment Laboratories said. The ... method involves creating alloys that solidify in a glass-like structure. Crushing the alloy creates a powder that, when applied at high temperature, bonds with other metals to form a very dense coating, with each particle about 50 nanometers in diameter. This process allows stronger atomic bonds in the material..." 12:09:01 PM
