Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

Innovators at NASA’s Glenn Research Center have developed a new means of avoiding and mitigating icing events for aircraft flying above 14,000 feet, dramatically improving aviation...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...

The critical angle lens reflector has commercial applications that supersede ordinary mirrored reflectors. The physics of the critical angle lens reflector are based on the optics...

Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for...

A new water purifier works better because it takes the shape of the rose.

Heavy-duty trucks, such as the 18-wheelers that transport many of the world's goods from farm or factory to market, are virtually all powered by diesel engines. They account for a...

It's dark on the back road as a motorist speeds toward the intersection. Up ahead, the stop sign blends with the night and in seconds a deadly crash occurs. According to the U.S....

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

Increase in bioethanol production throughout the US has led to an increase in the process coproduct — distiller’s grains with solubles (DGS). DGS can be used to feed...

Anew material was developed that can extract the key ingredient in the most common form of plastic from a mixture of other chemicals while consuming far less energy than usual....

Rocket engine testing requires a lot of light since all tests are filmed with high-speed cameras to monitor performance; however, those cameras have to adjust to the bright plume from a firing...

Fuel economy is a key factor in worldwide energy-consumption. One way to improve fuel economy is using driver feedback to promote efficient habits (eco-driving). Emerging research is looking into...

The MIT system can monitor the behavior of electronic devices within a building, a factory – and even a 270-foot Coast Guard cutter.

A new technology may lead to a more mainstream use of algal biofuels.

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...

Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Chemical and biological sensors based on nanowire or nanotube technologies exhibit...

Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then...
