(PhysOrg.com) -- The catalytic processes that facilitate the production of many chemicals and fuels could become much more environmentally friendly thanks to a breakthrough achieved by researchers from Lehigh and Rice Universities. http://www.physorg.com/news177006900.html Nanotechnology Mon, 09 Nov 2009 17:20:09 EST news177006900 (PhysOrg.com) -- For the first time, IBM researchers in Zurich, Switzerland, have taken a 3D image of an individual molecule. Using an atomic force microscope, the researchers constructed a "force map" of pentacene, an organic molecule just 1.4 nanometers long. As the researchers explain, the technique is roughly analogous to how an x-ray machine images bones in the human body by looking through flesh. In this case, the scientists could look through the electron cloud and see the atomic backbone of the molecule. http://www.physorg.com/news170685108.html Nanotechnology Fri, 28 Aug 2009 13:34:27 EST news170685108 A new microscope that views the subatomic universe -- the first of its kind in the world -- is being built for the University of Victoria, Canada, in collaboration with Hitachi High-Technologies. http://www.physorg.com/news166981239.html Nanotechnology Thu, 16 Jul 2009 16:41:18 EST news166981239 (PhysOrg.com) -- Carbon nanotubes are at the center of the nanoelectronics research movement, with scientists making great progress toward getting nanotube-based electronic devices into the hands of consumers. But one area of carbon nanotube research where there has been considerably less success is creating repeating, regular patterns onto individual nanotubes, a task necessary for a key goal of nanoelectronics: patterning transistors directly onto nanotube surfaces. http://www.physorg.com/news161950586.html Nanotechnology Tue, 19 May 2009 11:17:36 EST news161950586 How do white blood cells - immune system 'soldiers' - get to the site of infection or injury? To do so, they must crawl swiftly along the lining of the blood vessel - gripping it tightly to avoid being swept away in the blood flow - all the while searching for temporary 'road signs' made of special adhesion molecules that let them know where to cross the blood vessel barrier so they can get to the damaged tissue. http://www.physorg.com/news160649845.html Medicine & Health Mon, 04 May 2009 10:02:28 EST news160649845 Mapping the billions of connections in the brain is a grand challenge in neuroscience. The current method for mapping interconnected brain cells involves the use of room-size microscopes known as transmission electron microscopes (TEMs). Until now the process of mapping even small areas of the brain using these massive machines would have required several decades. In this week's open-access journal PLoS Biology, research teams at the University of Utah John A. Moran Eye Center and the University of Colorado at Boulder report technical advances that have reduced the time it takes to process high-speed "color" ultrastructure mapping of brain regions down to a few months. http://www.physorg.com/news157733857.html Biology Tue, 31 Mar 2009 15:59:13 EST news157733857 (PhysOrg.com) -- Science fiction fans still have another two months of waiting for the new Star Trek movie, but fans of actual science can feast their eyes now on the first movie ever of carbon atoms moving along the edge of a graphene crystal. Given that graphene - single-layered sheets of carbon atoms arranged like chicken wire - may hold the key to the future of the electronics industry, the audience for this new science movie might also reach blockbuster proportions. http://www.physorg.com/news157730577.html Nanotechnology Tue, 31 Mar 2009 15:03:37 EST news157730577 Arizona State University will be home to one of the world's most advanced electron microscopes, one that will enable researchers to do work essential to making significant advances in nanoscale aspects of solid state science and materials science and engineering. http://www.physorg.com/news155813933.html Physics Mon, 09 Mar 2009 10:39:20 EST news155813933 (PhysOrg.com) -- Researchers at Uppsala University have managed for the first time to measure magnetic properties in new materials quantitatively with the help of electron microscopy - with unparalleled precision. The secret behind the breakthrough is a successful elaboration of electron microscope technology. The findings, published in the scientific journal Physical Review Letters, means that the energy loss entailed in all electromagnetic materials can ultimately be minimized. http://www.physorg.com/news155317166.html Physics Tue, 03 Mar 2009 15:40:16 EST news155317166 Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices. http://www.physorg.com/news151607928.html Biology Mon, 19 Jan 2009 17:19:20 EST news151607928 Two new high-resolution transmission electron microscopes, co-financed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), are set to open up new opportunities for research in physics and materials science. The new research microscopes at RWTH Aachen University and the University of Ulm will enable exceptional, state-of-the-art developments in the field of electron optics in Germany and be available to a broad group of users. http://www.physorg.com/news148816641.html Physics Thu, 18 Dec 2008 09:57:21 EST news148816641
