More electronic materials opened up with new metal-organic framework

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.

Heavy-petroleum fuels raising vanadium emissions

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.

A new theory to describe widely used material

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.

Shoe-box-sized chemical detector

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.

Engineers create plants that glow

By embedding nanoparticles into the leaves of watercress, engineers have induced the plant to give off dim light for nearly four hours. They believe engineered plants will one day be bright enough to act as desk lamps or street lights.

One in five materials chemistry papers may be wrong, study suggests

Can companies rely on the results of one or two scientific studies to design a new industrial process or launch a new product? In at least one area of materials chemistry, the answer may be yes -- but only 80 percent of the time.
