Television just got brighter: UCLA engineers are obsessed with the next generation of LEDs

Making LEDs, or light-emitting diodes -- which illuminate today's plasma TV screens and cell phones more efficient -- cheaper and higher quality is the obsession that occupies the daily thoughts of UCLA Engineering professor Yang Yang and researcher Jinsong Huang. They have recently achieved the highest lumens per watt ever recorded for a red phosphorescent LED using a new combination of plastic, or polymer, infused liquid -- and they did it at half the current cost.

2. Researchers create new super-thin laser mirror
   02-13-2007 · EurekAlert!
   Engineers at UC Berkeley have created a new high-performance mirror that packs the same 99.9 percent reflective punch as current high-grade mirrors, but in a package that is 20 times thinner and easier to manufacture. The new mirror could dramatically improve the design and efficiency of next generation laser optics for such devices as high-definition DVD players, computer circuits and laser printers.

4. Advance by chemists may lead to better displays on laptop computers, cell phones
   09-17-2007 · EurekAlert!
   UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers. The research could lead to a brighter polarized light source for LEDs in laptop computers, cell phones and other consumer electronics devices.

7. 'Heftier' atoms reduce friction at the nanoscale, study led by Penn researcher reveals
   11-01-2007 · EurekAlert!
   A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface. 'Heavier' atoms vibrate at a lower frequency, reducing energy lost during sliding.

10. First-ever study: lack of critical lubricant causes wear in joints
    11-06-2007 · EurekAlert!
    For the first time, researchers have linked increased friction with early wear in the joints of animals. Work led by Brown University physician and engineer Gregory Jay, MD, shows mice that do not produce the protein lubricin begin to show wear in their joints less than two weeks after birth. This finding not only points up the protective power of lubricin but also suggests that it could be used to prevent joint wear after an injury.
