Efficiently harvesting hydrogen fuel from Sun using Earth-abundant materialsThu, 25 Sep 2014 14:12:32 EDT
Scientists have a new efficient way of producing hydrogen fuel from sunlight and water. By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using Earth-abundant materials as opposed to rare metals. World's smallest reference material is big plus for nanotechnologyThu, 25 Sep 2014 13:28:33 EDT
The National Institute of Standards and Technology recently issued Reference Material 8027, the smallest known reference material ever created for validating measurements of these human-made, ultrafine particles between 1 and 100 nanometers -- billionths of a meter -- in size. New organic semiconductor material: Organic tin in polymers increases their light absorptionThu, 25 Sep 2014 13:13:49 EDT
Researchers have integrated organic tin into semiconducting polymers (plastics) for the first time. Semiconducting polymers can be used, for example, for the absorption of sun light in solar cells. By incorporating organic tin into the plastic, light can be absorbed over a wide range of the solar spectrum. Natural gas usage will have little effect on carbon dioxide emissions, researchers findWed, 24 Sep 2014 11:36:59 EDT
Abundant supplies of natural gas will do little to reduce harmful U.S. emissions causing climate change, according to researchers. They found that inexpensive gas boosts electricity consumption and hinders expansion of cleaner energy sources, such as wind and solar. New mobile solar unit is designed to save lives when the power goes outWed, 24 Sep 2014 11:29:56 EDT
Brooke Ellison draws her own power from will, but the ventilator that keeps her alive requires uninterrupted electricity. Dr. Ellison is allowing scientists to field-test, at her home, the Nextek Power Systems STAR, a mobile solar generator.
