Stronger black solar coating that retains original color and absorption properties
(Phys.org) —Solar thermal panels developed at EPFL are are dressed up in unique and patented new materials. Researchers created a stronger black coating that retains its original color and thereby its absorption ...
Calculating waiting time at security control
Thermal imaging cameras at airports could calculate queues and check-in times better than systems that make estimates using Bluetooth and WiFi on passengers' mobiles.
Team develops device to detect biodiesel contamination
In 2010, a Cathay Pacific Airways plane was arriving in Hong Kong when the engine control thrusts seized up and it was forced to make a hard landing—injuring dozens. The potential culprit? Contaminated fuel.
Shape-shifting alloys hold promise
Imagine untwisting a finger-size spring, then holding the flame from a lighter underneath the unraveled section. Like magic, it twirls itself into a spring again because the metal alloy remembered its original ...
Fires in Northern Territory Australia
Northern Australia's bushfire season was well underway by the beginning of July, 2013. On July 23 the Aqua satellite flew over the region, allowing the Moderate Resolution Imaging Spectroradiometer (MODIS) ...
On a different wavelength: Scientists set out to create 'superspectral' camera
A team of engineers is setting out to create the world's first camera sensor capable of 'seeing' across a wide range of wavelengths.
Alphasat experiences heaven on Earth
(Phys.org)—Tucked away in a vacuum chamber for several months, Europe's largest telecom satellite has faced the harsh conditions it will deal with once it is launched into space this summer.
Bottom-up approach provides first characterization of pyroelectric nanomaterials
By taking a "bottom-up" approach, researchers at the University of Illinois at Urbana-Champaign have observed for the first time that "size does matter" in regards "pyroelectricity"—the current/voltage developed in response ...
CyPhy Works takes wraps off long-endurance UAVs (w/ video)
Pyroelectric nanogenerator charges Li-ion battery with harvested energy
Scientists use molecular layers to study nanoscale heat transfer
Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide ...
Omron sensor can do security and hot-soup checks (w/ Video)
Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. ...
Atlantis crew inspects 'thermal protection system'
The Atlantis crew on Saturday inspected the craft's thermal protection system, the outer barrier that protects it from the searing heat upon re-entry into the earth's atmosphere, NASA said.
