Rainbow-catching waveguide could revolutionize energy technologies

More efficient photovoltaic cells. Improved radar and stealth technology. A new way to recycle waste heat generated by machines into energy. All may be possible...

Crystals ripple in response to light

Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter...

Making silicon devices responsive to infrared light

Researchers have tried a variety of methods to develop detectors that are responsive to a broad range of infrared light — which could form...

Scientists develop heat-resistant materials that could vastly improve solar cell efficiency

Scientists have created a heat-resistant thermal emitter that could significantly improve the efficiency of solar cells. The novel component is designed to convert heat from...

How Engineers Revamped Spitzer to Probe Exoplanets

Now approaching its 10th anniversary, NASA's Spitzer Space Telescope has evolved into a premier observatory for an endeavor not envisioned in its original design:...

New material mimics calamari skin, is invisible to infrared cameras

What can the U.S. military learn from a common squid? A lot about how to hide from enemies, according to researchers at UC Irvine’s...
