Improved drinking water purification sand
	Scientists have developed a way to transform ordinary sand — a mainstay filter material used to purify drinking water throughout the world — into a "super sand" with five times the filtering capacity of regular sand.

Optical amplifier with ultra low noise
	Researchers at Chalmers have demonstrated an optical amplifier which can amplify light with extremely low noise. The breakthrough enables a reach increase for optical fiber signals from e.g. 1000 km to 4000 km, paving way for increasing the capacity of data communications.

"Ultrawideband" electronic technology medical applications
	Research by engineers has shown that “ultrawideband” electronic technology could contribute engineering solutions to an ambitious goal in the future of medicine – health monitoring with sophisticated “body-area networks.”

Intelligent cars that can prevent accidents?

Engineers have been developing a myriad safety systems aimed at preventing collisions: automated cruise control, a radar- or laser-based sensor system that slows a car when approaching another vehicle; blind-spot warning systems, which use lights or beeps to alert the driver to the presence of a vehicle he or she can’t see; and traction control and stability assist, which automatically apply the brakes if they detect skidding or a loss of steering control.

Nafion polymer used to improve polymer batteries and water purification
	Developing new materials depends on fully understanding the properties of today's materials.

Compact microspectrometer developed with improved resolution bandwidth
	A new microspectrometer architecture using compact doughnut-shaped resonators. An 81-channel instrument achieved 0.6-nanometer resolution over a spectral range of more than 50 nanometers with a footprint less than one square millimeter.

Improved LED light-emitting diode technology
	University of Miami professor at the College of Engineering, Jizhou Song, has helped design an light-emitting diode (LED) light that uses an array of LEDs 100 times smaller than conventional LEDs. The new device has flexibility, maintains lower temperature and has an increased life-span over existing LEDs.

Heat-treatment discovery that makes steel 7 percent stronger
	A Detroit entrepreneur surprised university engineers here recently, when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record – in less than 10 seconds.

Imaging technology diagnosing cardiovascular disease, diabetes
	Purdue researchers have developed a new type of imaging technology to diagnose cardiovascular disease and other disorders by measuring ultrasound signals from molecules exposed to a fast-pulsing laser.

Mobile temperature-sensing technology

National Institute of Standards and Technology (NIST) researchers are working to reduce the uncertainty associated with climate-change measurements using a mobile temperature-sensing technology made for tracking delicate or perishable, high-value packages in transit. Developed by international shipper FedEx and tested with help from NIST, the device connects to cell phone networks to provide users with near real-time information on the package's precise location, temperature, humidity, pressure, acceleration, elevation and exposure to light.
