Asphalt going green with nanoengineered cement in Phoenix

Phoenicians will return from the Memorial Day weekend to witness installation of the first "Cool Pavement" parking lot in central downtown Phoenix. This 90,000-square-foot temporary parking lot located between First, Second, Taylor and Polk Streets will now help cool the city this summer.

Nanotechnology visualization app for iPod and iPad

Independent developer Peter Burke today is pleased to announce iNanotube 1.1 for iOS, his new Education app that graphically instructs users about the detailed atomic structure of carbon nanotubes, a revolutionary class of wires only a few atoms across. Advanced 3D rendering algorithms provide detailed, animated renderings of the design and construction of carbon nanotubes, demonstrating and teaching the fundamentals of the atomic properties of these tiny wires.

Computational method helps nanoengineers choose self-assembling proteins

Engineering structures on the smallest possible scales - using molecules and individual atoms as building blocks - is both physically and conceptually challenging. An interdisciplinary team of researchers at the University of Pennsylvania has now developed a method of computationally selecting the best of these blocks, drawing inspiration from the similar behavior of proteins in making biological structures.

Researchers make new ground in remote quantum entanglement

Scientists were able to demonstrate how two remote atomic quantum systems can be prepared in a shared 'entangled' state. This means that one system is a single atom trapped in an optical resonator, and the other one is a Bose-Einstein condensate consisting of hundreds of thousands of ultracold atoms.

NIH grant ratchets up research in molecular motors works in living cells

Empowered by a $1.2 million grant from the National Institutes of Health, Arizona State University scientist Wayne Frasch is deciphering how one of the world's smallest molecular motors works in living cells. In the process, he is also casting light on a physics puzzle that has perplexed scientists for more than 40 years.

Tailoring the size of grains in a metal can make it both strong and ductile

Using a mechanical grinding technique that allowed them to control the structure of a metal's surface on the nanoscale, Ke Lu and colleagues from the Chinese Academy of Science's Institute for Metal Research in Shenyang have overcome the frustrating tradeoff between strength and brittleness to produce a protective copper surface that is both strong and ductile.
