| New conversion process turns biomass 'waste' into lucrative chemical products Posted: 17 Dec 2014 12:40 PM PST A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.  |
| Microscopy pencils patterns in polymers at the nanoscale Posted: 17 Dec 2014 12:39 PM PST Scientists have used advanced microscopy to carve out nanoscale designs on the surface of a new class of ionic polymer materials for the first time.  |
| Gothic cathedrals blend iron and stone Posted: 17 Dec 2014 04:43 AM PST Using radiocarbon dating on metal found in Gothic cathedrals, an interdisciplinary team has shown, for the first time through absolute dating, that iron was used to reinforce stone from the construction phase. This study sheds new light on the technical skill and intentions of cathedral builders.  |
| Smart window that tints and powers itself invented Posted: 17 Dec 2014 04:43 AM PST Scientists have developed a smart window which can darken or brighten without the need for an external power source.  |
