Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. http://www.physorg.com/news176389079.html Nanotechnology Mon, 02 Nov 2009 12:59:21 EST news176389079 (PhysOrg.com) -- CSIRO has developed a novel coating technology, "Quench Coat", to protect galvanised products from 'white rust' ? the form of zinc oxide that tarnishes freshly galvanised coatings, making them look dull. http://www.physorg.com/news176106672.html Chemistry Fri, 30 Oct 2009 07:50:01 EST news176106672 (PhysOrg.com) -- To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components is critical to the performance of the overall device. http://www.physorg.com/news175444804.html Nanotechnology Thu, 22 Oct 2009 15:52:12 EST news175444804 (PhysOrg.com) -- A NASA team is developing a transparent coating that mimics the self-cleaning properties of the lotus plant to prevent dirt from sticking to the surfaces of spaceflight gear and bacteria from growing inside astronaut living quarters. http://www.physorg.com/news172925702.html Chemistry Wed, 23 Sep 2009 11:55:57 EST news172925702 A non-toxic and environmentally friendly way to make tiny nanorods of zinc oxide has been developed for the first time by researchers in Saudi Arabia. The approach, described in the current issue of the International Journal of Nanoparticles, could allow the nanorods to be used safely in medical and for other applications. http://www.physorg.com/news169901230.html Nanotechnology Wed, 19 Aug 2009 11:49:13 EST news169901230 (PhysOrg.com) -- Growing - and precisely aligning - microscopic, spear-shaped zinc oxide crystals on a surface of single-crystal silicon, researchers at Missouri University of Science and Technology may have developed a method to make more efficient solar cells. http://www.physorg.com/news169223267.html Nanotechnology Tue, 11 Aug 2009 15:28:04 EST news169223267 Imagine if all you had to do to charge your iPod or your BlackBerry was to wave your hand, or stretch your arm, or take a walk? You could say goodbye to batteries and never have to plug those devices into a power source again. http://www.physorg.com/news157287591.html Nanotechnology Thu, 26 Mar 2009 12:00:36 EST news157287591 Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status. http://www.physorg.com/news156614210.html Nanotechnology Wed, 18 Mar 2009 16:57:10 EST news156614210 (PhysOrg.com) -- Duke University and United States Army scientists have found that a cheap and nontoxic sunburn and diaper rash preventative can be made to produce brilliant light best suited to the human eye. http://www.physorg.com/news148830246.html Nanotechnology Thu, 18 Dec 2008 13:44:06 EST news148830246 (PhysOrg.com) -- Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded. http://www.physorg.com/news145458616.html Nanotechnology Sun, 09 Nov 2008 13:10:16 EST news145458616
