Chicago skyscrapers go green, slash energy costs

Chicago's skyline is going green, as property managers install energy efficient tools like motion-detectors on office lights, in a project officials hope will inspire changes across the United States.

Icy exposure creates armored polymer high tech foams

(PhysOrg.com) -- Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could ...

At the nanoscale, graphite can turn friction upside down

(Phys.org)—If you ease up on a pencil, does it slide more easily? Sure. But maybe not if the tip is sharpened down to nanoscale dimensions. A team of researchers at the National Institute of Standards and Technology (NIST) ...

Size matters in nanocrystals' ability to adsorb, release gases

More efficient catalytic converters on autos, improved batteries and more sensitive gas sensors are some of the potential benefits of a new system that can directly measure the manner in which nanocrystals adsorb and release ...

'Sensing' danger

European researchers developed a novel gas sensor capable of detecting trace amounts of dangerous explosives with minimal false alarms. The technology should be important to a variety of gas separation and detection applications.

Engineers develop 'electronic nose' prototype

(Phys.org) -- Research by Nosang Myung, a professor at the University of California, Riverside, Bourns College of Engineering, has enabled a Riverside company to develop an "electronic nose" prototype that can detect small ...

The secret behind NIST's new gas detector? Chirp before sniffing

Trace gas detection, the ability to detect a scant quantity of a particular molecule -- a whiff of formaldehyde or a hint of acetone -- in a vast sea of others, underlies many important applications, from medical tests to ...
