Goodbye, fluorescent light bulbs: New lighting technology won't flicker, shatter or burn out
Say goodbye to that annoying buzz created by overhead fluorescent light bulbs in your office. Scientists at Wake Forest University have developed a flicker-free, shatterproof alternative for large-scale lighting.
Physicists observe 'campfire effect' in blinking nanorod semiconductors
When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased ...
NREL Finds a Way to Give LEDs the Green Light
(PhysOrg.com) -- Light bulbs that last 100 years and fill rooms with brilliant ambiance may become a reality sooner rather than later, thanks to a National Renewable Energy Laboratory discovery.
A bright idea: Philips lets flat lights out of lab
(AP) -- Someday, our ceilings and walls might radiate light, illuminating indoor spaces as brightly and evenly as natural daylight.
Tiny particles make LED light more pleasing
(AP) -- Light-emitting diodes are prime candidates for replacing inefficient incandescent bulbs, but have a few things working against them. They can provide a pleasing warm light or they can be energy-efficient, ...
Ionic liquids open door to better rare-earth materials processing
U.S. Department of Energy's Ames Laboratory and Critical Materials Institute materials chemist Anja Mudring is harnessing the promising qualities of ionic liquids, salts in a liquid state, to optimize processes ...
Home electricity use in US falling to 2001 levels
The average amount of electricity consumed in U.S. homes has fallen to levels last seen more than a decade ago, back when the smartest device in people's pockets was a Palm pilot and anyone talking about ...
Silicon-based nanoparticles could make LEDs cheaper, greener to produce
(Phys.org) —Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones ...
LEDs winning light race to save energy, the environment: report
Today's light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in ...
Alternative LED lighting combats energy crisis
Alternative lighting is emerging as a potent method to combat the energy crisis. Light-emitting diode (LED) lighting technologies could provide an innovative way to save energy and make wasteful lighting obsolete.
Researchers Develop Nanofiber-Based Technology to Make Energy-Efficient Lighting
(PhysOrg.com) -- RTI International has developed a revolutionary lighting technology that is more energy efficient than the common incandescent light bulb and does not contain mercury, making it environmentally ...
