| Heavy metals and hydroelectricity Posted: 01 Aug 2014 07:50 AM PDT Hydraulic engineering is increasingly relied on for hydroelectricity generation. However, redirecting stream flow can yield unintended consequences. Researchers from the U.S. and Peru have documented the wholesale contamination of the Lake JunÃn National Reserve by acid mine drainage from the Cerro de Pasco mining district.  |
| Posted: 01 Aug 2014 07:50 AM PDT Researchers have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic devices, or solar panels that could automatically clean themselves of dust and grit.  |
| Posted: 01 Aug 2014 07:42 AM PDT A new liquid metal alloy enables sodium-beta batteries to operate at lower temperatures, which could help the batteries store more renewable energy and strengthen the power grid.  |
| Chemists develop MRI technique for peeking inside battery-like devices Posted: 01 Aug 2014 06:12 AM PDT Chemists have developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly and can deliver high electrical power.  |
| Low-grade nonwoven cotton picks up 50 times own weight of oil Posted: 31 Jul 2014 11:55 AM PDT Researchers have recently discovered that low-grade cotton made into an absorbent nonwoven mat can collect up to 50 times its own weight in oil.  |
| Posted: 31 Jul 2014 11:54 AM PDT Scientists have discovered a new catalytic system for converting carbon dioxide (CO2) to methanol-a key commodity used to create a wide range of industrial chemicals and fuels. With significantly higher activity than other catalysts now in use, the new system could make it easier to get normally unreactive CO2 to participate in these reactions.  |
| New system to optimize public lighting power consumption Posted: 31 Jul 2014 06:46 AM PDT Scientists have designed an energy regulation system based on the combination of diverse electromagnetic elements. This system is able to efficiently reduce the luminous flux of lamps by reducing the voltage According to the researchers, this new system is strong and efficient and hardly needs any maintenance. Its size, weight and cost are lower than the systems used today based on power electronics.  |
