Medical uses for quantum dots -- tiny luminescent crystals -- could include image-guided surgery, light-activated therapies and sensitive diagnostic tests A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. The research, which will appear on May 20 in Nature Nanotechnology online, is likely the...

Kansas State University researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics. Vikas Berry, William H. Honstead professor of chemical engineering, has developed a novel process that uses a diamond knife to cleave graphite into graphite nanoblocks, which are precursors for graphene quantum dots. These nanoblocks are then exfoliated to produce...

New Research Could Peg Quantum Dots As Future Of Lighting

Researchers are looking to white-light quantum dots as the future of lighting. White-light quantum dots are ultra-small fluorescent beads of cadmium selenide that are able to convert blue light produced by an LED into a warm white light similar to an incandescent light. Vanderbilt University researchers are reporting that they have successfully boosted the fluorescent efficiency in nano crystals from an original level of three percent to as high as 45 percent.  This feat proves...

Single Nanomaterial Yields Many Laser Colors

Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same elements. In experiments, light amplification required much less power than previous attempts at the technology. The team´s prototypes are the first lasers of their kind. Red, green, and blue lasers have become small...

New technique holds promise for better understanding of brain disorders By harnessing quantum dots–tiny light-emitting semiconductor particles a few billionths of a meter across–researchers at the University of Washington (UW) have developed a new and vastly more targeted way to stimulate neurons in the brain. Being able to switch neurons on and off and monitor how they communicate with one another is crucial for understanding–and, ultimately, treating–a host of...

Berkeley Lab Researchers Discover Why Pure Quantum Dots and Nanorods Shine Brighter To the lengthy list of serendipitous discoveries — gravity, penicillin, the New World — add this: Scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they´ve also discovered how to correct the problem. A...

A robust new architecture enables optimization for quantum-dot displays By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated a robust new architecture for quantum-dot light-emitting devices (QD-LEDs). Quantum dots are very tiny crystals that glow with bright, rich colors when stimulated by an electric current. QD-LEDs are expected to find applications in television and computer...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
