Smarter programming of stoplights could improve efficiency of urban traffic
Sitting in traffic during rush hour is not just frustrating for drivers; it also adds unnecessary greenhouse gas emissions to the atmosphere.
When temperature goes quantum
A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential ...
3D-printed aerogels improve energy storage
A new type of graphene aerogel will make for better energy storage, sensors, nanoelectronics, catalysis and separations.
Graphene produces more efficient transport of a semiconducting polymer film
The new wonder material graphene has fantastic properties, for example flexibility, transparency and high charge carrier mobility. A study by an international team led by David Barbero, assistant professor ...
A more efficient, lightweight and low-cost organic solar cell
For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, ...
California puzzles over safety of driverless cars
California's Department of Motor Vehicles will miss a year-end deadline to adopt new rules for cars of the future because regulators first have to figure out how they'll know whether "driverless" vehicles ...
Unpacking the past: Identifying a key evolutionary step in E. coli metabolism
Ballistic transport in graphene suggests new type of electronic device
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room ...
Driverless shuttle will be on the move in UK
NYC subways slowly upgrading from 1930s-era technology
New York City's subways—the nation's biggest mass transit network—serve more than 6 million daily riders who depend largely on a signal system that dates back to the Great Depression.
App, beacons guide travel on underground for vision-impaired
Study shows novel pattern of electrical charge movement through DNA
Electrical charges not only move through wires, they also travel along lengths of DNA, the molecule of life. The property is known as charge transport.
Combating bacterial biofilm formation with titanium encrusted with gold nanoparticles
Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your rugged, salty skin. Surgeries to implant medical devices often give such bacteria the opportunity needed to ...
