A new theory to describe widely used material
Fri, 15 Dec 2017 14:33:00 EST
A new theoretical model explains the coupling between ions and electrons in the widely used conducting polymer PEDOT:PSS. The model has profound implications for applications in printed electronics, energy storage in paper, and bioelectronics.
Heavy-petroleum fuels raising vanadium emissions
Fri, 15 Dec 2017 12:10:52 EST
Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.
Shoe-box-sized chemical detector
Fri, 15 Dec 2017 11:15:59 EST
A chemical sensor prototype will be able to detect 'single-fingerprint quantities' of substances from a distance of more than 100 feet away, and its developers are working to shrink it to the size of a shoebox.
More electronic materials opened up with new metal-organic framework
Fri, 15 Dec 2017 10:51:52 EST
More materials for electronic applications could be identified, thanks to the discovery of a new metal-organic framework (MOF) that displays electrical semiconduction with a record high photoresponsivity, by a global research collaboration.
New technique could make captured carbon more valuable
Fri, 15 Dec 2017 09:44:46 EST
Carbon capture could help coal plants reduce emissions if economic challenges can be overcome. Turning captured carbon into a useable product is one solution. Scientists have developed an efficient process for turning captured carbon dioxide into syngas that can be used to make fuels and chemicals.
