Scientists have experimentally verified a theory suggesting that hot electrons could double the output of solar cells. The researchers, from Boston College, have built solar cells that successfully use hot electrons to increase the cells' power ouput. Although the power increase is small, the concept could lead to solar cells that break conventional efficiency limits. http://www.physorg.com/news180365359.html Nanotechnology Fri, 18 Dec 2009 13:44:26 EST news180365359 (PhysOrg.com) -- Techniques recently invented by researchers at the California Institute of Technology -- which allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter -- have been used to image the evanescent electrical fields produced by the interaction of electrons and photons, and to track changes in atomic-scale structures. http://www.physorg.com/news180191808.html Physics Wed, 16 Dec 2009 13:17:45 EST news180191808 (PhysOrg.com) -- European researchers have developed state-of-the-art nanowire 'growing' technology, opening the way for faster, smaller microchips and creating a promising new avenue of research and industrial development in Europe. http://www.physorg.com/news180169791.html Nanotechnology Wed, 16 Dec 2009 07:40:01 EST news180169791 (PhysOrg.com) -- Microchip manufacturers have long faced challenges miniaturizing transistors, the key active components in nearly every modern electronic device, which are used to amplify or switch electronic signals. http://www.physorg.com/news179590555.html Nanotechnology Wed, 09 Dec 2009 14:16:53 EST news179590555 Scientists at Singapore's Institute of Microelectronics (IME) have developed a rapid and sensitive integrated system to test simultaneously for specific cardiac biomarkers in finger prick amount of blood. http://www.physorg.com/news179508948.html Medicine & Health Tue, 08 Dec 2009 16:30:05 EST news179508948 Air Force Office of Scientific Research and National Science Foundation-funded professor, Dr. Xiang Zhang has demonstrated at the University of California, Berkeley the world's smallest semiconductor laser, which may have applications to the Air Force in communications, computing and bio-hazard detection. http://www.physorg.com/news179431591.html Physics Mon, 07 Dec 2009 18:50:02 EST news179431591 (PhysOrg.com) -- Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable batteries and supercapacitors in the form of everyday paper. http://www.physorg.com/news179427849.html Nanotechnology Mon, 07 Dec 2009 17:04:51 EST news179427849 (PhysOrg.com) -- A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles. http://www.physorg.com/news178459486.html Nanotechnology Thu, 26 Nov 2009 14:00:05 EST news178459486 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) -- University of Toronto researchers continue to uncover the mysteries of space. But even the best astronauts in the world are stymied if the spaceship doesn't launch. When the countdown stops, it is often because a hydrogen leak has been detected. One small malfunction in the sensing device can mean millions of dollars lost. http://www.physorg.com/news177096977.html Nanotechnology Tue, 10 Nov 2009 19:10:02 EST news177096977 Of the many characteristic traits a drug can have, one of the most desirable is the ability for a drug to be swallowed and absorbed into the bloodstream through the gut. Some drugs, like over-the-counter aspirin, lend themselves to this mode of delivery and are trivial to take. They can be pressed into a pill and swallowed. Other drugs cannot be swallowed and must be administered instead through more complicated routes. Insulin, for instance, must be injected. http://www.physorg.com/news176994804.html Biology Mon, 09 Nov 2009 15:00:02 EST news176994804 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 Danish nanophysicists have developed a new method for manufacturing the cornerstone of nanotechnology research - nanowires.
