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.
The laboratory " Structure - Activité of Normal + Pathologic Biomolecules - SANPB ", Inserm / UEVE U829 (Genopole Evry, France) in collaboration with the Material Centre of Mines-ParisTech (Evry, France), the NRG - UMR 5060 CNRS / UTBM (Technology University of Belfort-Montbéliard) and the Physic Institute of Stuttgart University (Germany) discovered a novel route to fabricate fluorescent nanoparticles from diamond microcrystals. Results are published in Nanotechnology June10 2009 issue.
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious.
The data eyeglasses can read from the engineer's eyes which details he needs to see on the building plans. A CMOS chip with an eye tracker in the microdisplay makes this possible. The eyeglasses are connected to a PDA, display information and respond to commands.
Sleep disturbances increase as we age. Some studies report more than half of seniors 65 years of age or older suffer from chronic sleep disturbances. Researchers have long believed that the sleep disturbances common among the elderly often result from a disruption of the body's circadian rhythms-biological cycles that repeat approximately every 24 hours.
With thousands in attendance, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory was officially dedicated today, setting into motion the next chapter of one of the country's greatest scientific assets.
Researchers from around the world will present the latest breakthroughs in electro-optics, lasers and the application of light waves at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) May 31 to June 5 at the Baltimore Convention Center in Baltimore.
A new turnkey diode laser system from Coherent (Santa Clara, CA) (Nasdaq: COHR) offers modular flexibility and output power of up to 400W at 976 nm.
During May and June 2009, scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Argonne National Laboratory, and the University of Colorado at Boulder will use high-tech scanners - analogous to those used in medical settings - to make observations of clouds.
