University of Florida - New, light-driven nanomotor is simpler, more promising, scientists say
2009 JUN 22 - (VerticalNews.com) -- Sunflowers track the sun as it moves from east to west. But people usually have to convert sunlight into electricity or heat to put its power to use.
Now, a team of University of Florida chemists is the latest to report a new mechanism to transform light straight into motion ? albeit at a very, very, very tiny scale.
In a paper expected to appear soon in the online edition of the journal Nano Letters, the UF team reports building a new type of "molecular nanomotor" driven only by photons, or particles of light. While it is not the first photon-driven nanomotor, the almost infinitesimal device is the first built entirely with a single molecule of DNA ? giving it a simplicity that increases its potential for development, manufacture and real-world applications in areas ranging from medicine to manufacturing, the scientists say ...read more
University of Florida - Team of researchers achieves major step toward faster chips
2009 MAY 25 - (VerticalNews.com) -- New research findings could lead to faster, smaller and more versatile computer chips.
A team of scientists and engineers from Stanford, the University of Florida and Lawrence Livermore National Laboratory is the first to create one of two basic types of semiconductors using an exotic, new, one-atom-thick material called graphene. The findings could help open the door to computer chips that are not only smaller and hold more memory -- but are also more adept at uploading large files, downloading movies, and other data- and communication-intensive tasks ...read more
University of Florida - Researchers: Molecular forklifts overcome obstacle to 'smart dust'
2009 FEB 2 - (VerticalNews.com) -- Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood.
Now, University of Florida engineering researchers have tapped the working parts of cells to clear a major hurdle to creating such "smart dust." The feat, which signifies a new approach to technology known as the "lab on a chip," is to be reported in the journal Nature Nanotechnology ...read more
