Shining new light on air pollutants using entangled porous frameworks

Certain types of pollution monitoring may soon become considerably easier. A group of researchers centered at Kyoto University has shown that a newly-formulated entangled framework of porous crystals (porous coordination polymers, or PCPs) can not only capture a variety of common air pollutants, but that the mixtures then glow in specific, easily-detected colors.

Imec launches new research program on high-bandwidth optical I/O

Imec announces the launch of a new industrial affiliation program on high-bandwidth optical input/output (I/O). The primary objective of the new program, which is part of imec's research platform on deep-submicron CMOS scaling, is to explore the use of optical solutions for realizing high-bandwidth I/O between CMOS chips.

The practical full-spectrum solar cell comes closer

Although full-spectrum solar cells have been made, none yet have been suitable for manufacture at a consumer-friendly price. Now Wladek Walukiewicz, who leads the Solar Energy Materials Research Group in the Materials Sciences Division (MSD) at Berkeley Lab, and his colleagues have demonstrated a solar cell that not only responds to virtually the entire solar spectrum, it can also readily be made using one of the semiconductor industry's most common manufacturing techniques.

GRIN plasmonics: A practical path to superfast computing, ultrapowerful optical microscopy and invisibility carpet-cloaking devices

They said it could be done and now they've done it. What's more, they did it with a GRIN. A team of researchers have carried out the first experimental demonstration of GRIN - for gradient index - plasmonics, a hybrid technology that opens the door to a wide range of exotic optics, including superfast computers based on light rather than electronic signals, ultra-powerful optical microscopes able to resolve DNA molecules with visible light, and 'invisibility' carpet-cloaking devices.
