Recycling old car batteries into solar cells: Environmental twofer could recycle lead batteries to make solar cellsMon, 18 Aug 2014 11:34:28 EDT
This could be a classic win-win solution: A system proposed by researchers recycles materials from discarded car batteries -- a potential source of lead pollution -- into new, long-lasting solar panels that provide emissions-free power. Insights into a new class of semiconducting materialsTue, 12 Aug 2014 16:35:29 EDT
A new paper describes investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic 'hybrid' perovskites. Making eco-friendly 'pre-fab nanoparticles': Versatile, water-soluble nano-modulesTue, 12 Aug 2014 16:33:20 EDT
Materials chemists, polymer scientists and device physicists have reported on a breakthrough technique for controlling assembly of nanoparticles over multiple length scales that may allow cheaper, ecologically friendly manufacture of organic photovoltaics and other electronic devices. Simulation models optimize water powerWed, 06 Aug 2014 09:47:10 EDT
The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20,000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system. LEDs made from 'wonder material' perovskiteTue, 05 Aug 2014 13:21:40 EDT
Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future. A hybrid form of perovskite -- the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon -- has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible color displays.
