The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. However, se-vere problems arise due to quantum-mechanical phenomena when conven-tional structures are simply made smaller and reach the nanometer scale. Therefore current research focuses on the so-called bottom-up approach: the engineering of functional structures with the smallest possible building blocks - single atoms and molecules. http://www.physorg.com/news177249897.html Nanotechnology Thu, 12 Nov 2009 12:09:44 EST news177249897 Silicon nanowires are attracting significant attention from the electronics industry due to the drive for ever-smaller electronic devices, from cell phones to computers. The operation of these future devices, and a wide array of additional applications, will depend on the mechanical properties of these nanowires. New research from North Carolina State University shows that silicon nanowires are far more resilient than their larger counterparts, a finding that could pave the way for smaller, sturdier nanoelectronics, nanosensors, light-emitting diodes and other applications. http://www.physorg.com/news177171851.html Nanotechnology Wed, 11 Nov 2009 14:24:43 EST news177171851 (PhysOrg.com) -- Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology. http://www.physorg.com/news176396559.html Nanotechnology Mon, 02 Nov 2009 15:04:34 EST news176396559 Danish nanophysicists have developed a new method for manufacturing the cornerstone of nanotechnology research - nanowires.

A key component of these tiny circuits is stable nanowires that work reliably for a decade or more. Currently, however, nanowires often fail after anywhere from a few days to a few months, due to prolonged electrical stressing. http://www.physorg.com/news172414056.html Nanotechnology Thu, 17 Sep 2009 13:48:08 EST news172414056 (PhysOrg.com) -- Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices.
