| Water leads to chemical that gunks up biofuels production Posted: 20 Aug 2014 01:43 PM PDT Trying to understand the chemistry that turns plant material into the same energy-rich gasoline and diesel we put in our vehicles, researchers have discovered that water in the conversion process helps form an impurity which, in turn, slows down key chemical reactions.  |
| Turning waste from rice, parsley and other foods into biodegradable plastic Posted: 20 Aug 2014 08:05 AM PDT Your chairs, synthetic rugs and plastic bags could one day be made out of cocoa, rice and vegetable waste rather than petroleum, scientists are now reporting. The novel process they developed and their results could help the world deal with its agricultural and plastic waste problems.  |
| A semi-artificial leaf faster than 'natural' photosynthesis Posted: 20 Aug 2014 06:16 AM PDT Cooperation between chemists and biologists has resulted in a new method for the very efficient integration of photosynthetic proteins in photovoltaics. Their research offers a new immobilization strategy that yields electron transfer rates exceeding for the first time rates observed in natural photosynthesis. This discovery opens the possibility for the construction of semi-artificial leaves functioning as photovoltaic devices with drastically increased performance.  |
| Bubbling down: Discovery suggests surprising uses for common bubbles Posted: 19 Aug 2014 09:59 AM PDT In a finding with scientific and industrial applications, researchers find that bursting bubbles can push tiny particles down into a liquid as well as up into the air.  |
| Major step toward optical computing: Non-metallic metamaterial used to 'compress' and contain light Posted: 19 Aug 2014 09:59 AM PDT Engineering researchers are designing nano-optical cables small enough to replace the copper wiring on computer chips. The advance could result in radical increases in computing speeds and reduced energy use by electronic devices.  |
| Posted: 18 Aug 2014 05:41 PM PDT Researchers have developed a technology that allows a material to automatically read its environment and adapt to mimic its surroundings. Cunjiang Yu, assistant professor of mechanical engineering at the University of Houston and lead author of the paper, said the system was inspired by the skins of cephalopods, a class of marine animals which can change coloration quickly, both for camouflage and as a form of warning.  |
| Engineering long-lasting joint lubrication by mimicking nature Posted: 18 Aug 2014 10:52 AM PDT By finding a way to bind a slippery molecule naturally found in the fluid that surrounds healthy joints, researchers have engineered surfaces that have the potential to deliver long-lasting lubrication at specific spots throughout the body. The finding could eventually offer a new way to ease the pain of arthritic joints, keep artificial joints working smoothly or even make contact lenses more comfortable.  |
