OSRAM light emitting diodes firmly in the headlights
2007-12-22 |
LEDs from OSRAM Opto Semiconductors have made the leap into the mid range of automobiles now that they are being used for functional lighting on the Audi A4. In the new headlights on the Audi A4 the LEDs are providing high-visibility daytime running light and stylish good looks - a successful combination of innovative headlight design and high levels of safety. This is an important first step toward the widespread use of LED technology in vehicle headlights.

Researchers solve fuel-cell membrane structure conundrum
2007-12-13 |
|
Fuel-cell cars are reaching commercial viability in today's increasingly eco-conscious society, but despite their promise, even scientists have struggled to explain just how the fuel-cell's central component - the proton exchange membrane - really works.

new way to manipulate light a million times more efficiently than before
2007-11-23 |
|
20 Nov 2007 - Using a special hollow-core photonic crystal fibre, a team at the University of Bath, UK, has opened the door to what could prove to be a new sub-branch of photonics, the science of light guidance and trapping. The team, led by Dr Fetah Benabid, reports on the discovery, which relates to the emerging attotechnology, the ability to send out pulses of light that last only an attosecond, a billion billionth of a second.

New Class Of Catalyst For Fuel Cells Beats Pure Platinum By A Mile
2007-10-25 |
|
ScienceDaily (Oct. 24, 2007) ¡ª Hydrogen fuel cells will power the automobiles of the future; however, they have so far suffered from being insufficiently competitive. At the University of Houston, Texas, USA, a team led by Peter Strasser has now developed a new class of electrocatalyst that could help to improve the capacity of fuel cells. The active phase of the catalyst consists of nanoparticles with a platinum-rich shell and a core made of an alloy of copper, cobalt, and platinum. This catalyst demonstrates the highest activity yet observed for the reduction of oxygen.
