Berkeley Lab researchers have engineered a new class of bowtie-shaped devices that capture, filter and steer light at the nanoscale. These "nano-colorsorter" devices act as antennae to focus and sort light in tiny spaces, a useful technique for harvesting broadband light for color-sensitive filters and detectors. http://www.physorg.com/news177251056.html Nanotechnology Thu, 12 Nov 2009 12:25:15 EST news177251056 Inside a cramped back room at Rushford Hypersonic, a start-up headquartered in southeastern Minnesota, sits a cube-like machine that throws a mean atomic fastball. At the push of a button, the reactor hurls atoms toward a substrate material at eight times faster than the speed of sound. http://www.physorg.com/news176637826.html Nanotechnology Thu, 05 Nov 2009 11:10:02 EST news176637826 (PhysOrg.com) -- In the past, restoration of paintings and other old artwork often involved application of acrylic resins to consolidate and protect them. One of the most important tasks for modern restorers is thus to remove these layers, because it turns out that acrylic resins not only drastically change the optics of the treated artwork, but in many cases they accelerate their degradation. http://www.physorg.com/news175805911.html Chemistry Mon, 26 Oct 2009 19:59:12 EST news175805911 Imagine a particle so small it would take a million of them to stretch across the period at the end of this sentence. Imagine such particles could help catch cancer cells floating in your bloodstream before they could metastasize to the liver, bones, brain or other organs. Or replace the insulin-making cells of your pancreas to cure diabetes. Or, conversely, attack the linings of your lungs with the lethality of asbestos. http://www.physorg.com/news174670932.html Nanotechnology Tue, 13 Oct 2009 18:20:03 EST news174670932 Clemson bioengineer Frank Alexis is designing new ways to target drugs and reduce the chances for side effects. http://www.physorg.com/news174219683.html Nanotechnology Thu, 08 Oct 2009 12:00:02 EST news174219683 The U.S. Environmental Protection Agency today outlined a new research strategy to better understand how manufactured nanomaterials may harm human health and the environment. Nanomaterials are materials that are between approximately one and 100 nanometers. These materials are currently used in hundreds of consumer products, including sunscreen, cosmetics and sports equipment. http://www.physorg.com/news173453869.html Nanotechnology Tue, 29 Sep 2009 14:50:01 EST news173453869 (PhysOrg.com) -- On this day in 1989, IBM Fellow Don Eigler became the first person in history to move and control an individual atom. Shortly thereafter, on November 11 of that year, Eigler and his team used a custom-built microscope to spell out the letters IBM with 35 xenon atoms. This unprecedented ability to manipulate individual atoms signaled a quantum leap forward in in nanoscience experimentation and heralded in the age of nanotechnology. http://www.physorg.com/news173344987.html Nanotechnology Mon, 28 Sep 2009 08:23:35 EST news173344987 New data on signaling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer. For many decades scientists have puzzled on "How signaling proteins transport and organize in specific areas of the cell?" Researchers from Nano-Science Center and Department of Neuroscience and Pharmacology at the University of Copenhagen, Denmark, provide yet unrecognized clues to solve this mystery. http://www.physorg.com/news172769341.html Chemistry Mon, 21 Sep 2009 17:40:05 EST news172769341 The burgeoning research fields of nanoscience and nanotechnology are commonly thought to be highly multidisciplinary because they draw on many areas of science and technology to make important advances. http://www.physorg.com/news171521941.html Nanotechnology Mon, 07 Sep 2009 06:16:39 EST news171521941 (PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed on a photonic chip and it is major step forward in the quest to realise a super-powerful quantum computer. http://www.physorg.com/news171213314.html Physics Thu, 03 Sep 2009 16:15:49 EST news171213314 Mr Pradyumna Thiruvenkatanathan, a second year doctoral student in Engineering, is the recipient of the best student paper award in the sensors and transducers sub-field at the IEEE Frequency Control conference. The IEEE Frequency Control conference is a premier event highlighting research in the areas of frequency and timing, frequency control and related technologies including Micro-Electro-Mechanical Systems (MEMS). http://www.physorg.com/news171128812.html Technology Wed, 02 Sep 2009 17:10:03 EST news171128812 With $20 million over five years from the National Science Foundation, UC Irvine scientists hope to become the first ever to make real-time videos of single molecules in action - a feat that has proved elusive because size and time scales are so small. http://www.physorg.com/news169754661.html Nanotechnology Mon, 17 Aug 2009 19:05:35 EST news169754661 It appears that bacteria can squeeze through practically anything. In extremely small nanoslits they take on a completely new flat shape. Even in this squashed form they continue to grow and divide at normal speeds. This has been demonstrated by research carried out at TU Delft's Kavli Institute of Nanoscience. The results will be appearing this week in the online edition of the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS) and as the cover article in the September 1 print issue of PNAS. http://www.physorg.com/news169744761.html Nanotechnology Mon, 17 Aug 2009 16:50:04 EST news169744761 Researchers at TU Delft, The Netherlands, have succeeded in measuring the influence of a single electron on a vibrating carbon nanotube. This research can be important for work such as the development of ultra-small measuring instruments.  The scientists have published their results on Thursday 23 July in the online version of the scientific journal Science. http://www.physorg.com/news167646198.html Nanotechnology Fri, 24 Jul 2009 09:24:30 EST news167646198 Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time. http://www.physorg.com/news167490673.html Nanotechnology Wed, 22 Jul 2009 14:11:57 EST news167490673
