Yale scientists have developed an ultra-thin coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries, one of the most promising areas of energy research today.
In a study published online March 20 in the Proceedings of the National Academy of Sciences, researchers describe the new material — a dendrimer-graphene oxide composite film — which can be applied to any sulfur cathode. A cathode is the positive terminal on a battery.
Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will track the environmental performance of U.S. power producers and compare current emissions to historical data collected nationwide for more than two decades. A quarterly press release will inform interested parties of power sector carbon emissions performance trends. In addition, CMU will provide an online resource for a wide variety of power sector emissions data and forecasts.
A research team led by University of Toronto's Faculty of Applied Science & Engineering ‘squashes’ the shape of nanoparticles, enabling inexpensive lasers that emit light in a customized rainbow of colours
Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white.
Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decades by snow and ice. Long-abandoned tents and snowmobiles were being unveiled by melting of the ice cap, and that helped inspire a study that suggests a disturbing climate change signal.
Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study by Smithsonian scientists published in the Proceedings of the National Academy of Sciences. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone—a low-oxygen area that snuffs out marine life—rather than by ocean warming or acidification.
Northern North Dakota – the Souris River, Devils Lake and the northernmost reaches of the Red River – has the greatest risk of major flooding this spring, while moderate flooding is possible over southern Idaho in the Snake River basin, according to NOAA’s Spring Outlook released today.
