Engineering a better solar cell: Defects in popular perovskites pinpointedThu, 30 Apr 2015 15:50:53 EDT
A new study demonstrates that perovskite materials - superefficient crystal structures that have recently taken the scientific community by storm - contain flaws that can be engineered to improve solar cells and other devices even further. Artificial photosynthesis could help make fuels, plastics and medicineWed, 29 Apr 2015 10:48:11 EDT
The global industrial sector accounts for more than half of the total energy used every year. Now scientists are inventing a new artificial photosynthetic system that could one day reduce industry's dependence on fossil fuel-derived energy by powering part of the sector with solar energy and bacteria. The system converts light and carbon dioxide into building blocks for plastics, pharmaceuticals and fuels -- all without electricity. Electrical power converter allows grid to easily accept power from renewable energyMon, 27 Apr 2015 10:13:17 EDT
Engineering researchers have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system. A video camera that powers itselfWed, 15 Apr 2015 10:29:24 EDT
Scientists have invented a prototype video camera that is the first to be fully self-powered -- it can produce an image each second, indefinitely, of a well-lit indoor scene. They designed a pixel that can not only measure incident light but also convert the incident light into electric power. Harvesting energy from electromagnetic wavesTue, 14 Apr 2015 12:58:13 EDT
Researchers have developed a novel design for electromagnetic energy harvesting based on the "full absorption concept." This involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power -- enabling full absorption of incident waves at a specific range of frequencies and polarizations.
