In 2006, Austin, Texas, became the first city in the country to ban a commonly used pavement sealant over concerns that it was a major source of cancer-causing compounds in the environment. Eight years later, the city’s action seems to have made a big dent in the targeted compounds’ levels — researchers now report that the concentrations have dropped significantly.
A simple, scalable method of making strong, stretchable graphene oxide fibers that are easily scrolled into yarns and have strengths approaching that of Kevlar is possible, according to Penn State and Shinshu University, Japan, researchers.

From such courses as Pesticides, Insecticides and the Environment to Philosophy of Science, Cornell University’s newest chemistry majors have a wide range of electives they can now choose from to fill out the 60-credit major.
By levitating a bead of ceramic oxide, heating it with a 400-watt carbon dioxide laser, then shooting the molten material with X-rays and neutrons, scientists with the U.S. Department of Energy's Oak Ridge and Argonne national laboratories have revealed unprecedented detail of the structure of high-temperature liquid oxides.
Work will improve processors, drivers, controllers and other circuits.
Particle sizing methodologies range from straightforward sieving and sedimentation analysis to advanced laser-based light scattering techniques, microscopy/imaging, nanoparticle tracking analysis, and others.

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.
Think those flat, glassy solar panels on your neighbour’s roof are the pinnacle of solar technology? Think again.
