| Ultrasound thermography identifying flawed wood |
 |
Is there a hairline crack in the oak table? Was the window frame glued badly? Ultrasound thermography can reliably identify material defects during the production of wooden items. This allows rejects to be caught quickly and eliminated, and faulty goods to be repaired in good time. |
| Data at 100 Mbit/s without any losses, using LEDs |
|
Regular LEDs can be turned into optical WLAN with only a few additional components thanks to visible light communication (in short, VLC). The lights are then not just lighting up, they also transfer data. They send films in HD quality to your iPhone or laptop, with no loss in quality, quickly and safely. |
| Runway radar for safety |
 |
Airplanes undergo significant stresses during take-off and landing, and parts often become detached, putting subsequent runway users at risk. Until now, airport staff have had to monitor runways without technical assistance – an activity that is prone to errors. A new radar system is set to increase safety at airports. |
| An Unexpected relation among electric and magnetic fields |
 |
Berkeley Lab scientists and their colleagues have discovered a new relation among electric and magnetic fields and differences in temperature, which may lead to more efficient thermoelectric devices that convert heat into electricity or electricity into heat. |
| 3-D photonic crystals advance solar cells |
 |
In an advance that could open new avenues for solar cells, lasers, metamaterials and more, researchers at the University of Illinois have demonstrated the first optoelectronically active 3-D photonic crystal. |
| Economic transition to renewable energy - looking good! |
|
The transition to renewable energy is set to deliver an economic pay off as well in the years to come. Various studies show that a shift to alternative energy sources will raise the GNP in the coming decade and create new jobs, as Prof. Eicke Weber, spokesperson for the Fraunhofer Energy Alliance, points out. Fraunhofer scientists are developing concepts and solutions for the transition as it takes shape. |
