| Clearing a path for electrons in polymers: Closing in on the speed limits Posted: 05 Nov 2014 10:19 AM PST A new class of low-cost polymer materials, which can carry electric charge with almost no losses despite their seemingly random structure, could lead to flexible electronics and displays which are faster and more efficient. |
| Engineered for tolerance, bacteria pump out higher quantity of renewable gasoline Posted: 05 Nov 2014 09:20 AM PST An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding is a significant step toward developing a bacterial strain that can yield industrial quantities of renewable bio-gasoline. |
| Breaking down BPA and similar pollutants with sunlight, nanoparticles and graphene Posted: 05 Nov 2014 07:13 AM PST Many pollutants with the potential to meddle with hormones -- with bisphenol A, better known as BPA, as a prime example -- are already common in the environment. In an effort to clean up these pollutants found in the soil and waterways, scientists are now reporting a novel way to break them down by recruiting help from nanoparticles and light. |
| Longhorn beetle inspires ink to fight counterfeiting Posted: 05 Nov 2014 07:12 AM PST From water marks to colored threads, governments are constantly adding new features to paper money to stay one step ahead of counterfeiters. Now a longhorn beetle has inspired yet another way to foil cash fraud, as well as to produce colorful, changing billboards and art displays. Researchers report a new kind of ink that mimics the beetle's color-shifting ability in a way that would be long-lasting and difficult to copy. |
| Jet-fueled electricity at room temperature: Fuel cell can run without high heat Posted: 05 Nov 2014 05:37 AM PST Engineers have now developed the first room-temperature fuel cell that uses enzymes to help jet fuel produce electricity without needing to ignite the fuel. These new fuel cells can be used to power portable electronics, off-grid power and sensors. |
