New Technique Shrinks Size Of Nanotechnology Circuitry Boulder CO (SPX) Apr 20, 2009 
A University of Colorado at Boulder team has developed a new method of shrinking the size of circuitry used in nanotechnology devices like computer chips and solar cells by using two separate colors of light. Like current methods in the nanoengineering field, one color of light inscribes a pattern on a substrate, said CU-Boulder Assistant Professor Robert McLeod of the electrical, computer ... read moreCarbon Nanotubes Are Superior To Metals For Electronics 
Buffalo NY (SPX) Mar 27, 2009In the quest to pack ever-smaller electronic devices more densely with integrated circuits, nanotechnology researchers keep running up against some unpleasant truths: higher current density induces electromigration and thermomigration, phenomena that damage metal conductors and produce heat, which leads to premature failure of devices. But University at Buffalo researchers who study electr ... more

No Small Measure: Origins Of Nanorod Diameter Discovered
Troy NY (SPX) Mar 27, 2009A new study answers a key question at the very heart of nanotechnology: Why are nanorods so small? Researchers at Rensselaer Polytechnic Institute have discovered the origins of nanorod diameter, demonstrating that the competition and collaboration among various mechanisms of atomic transport hold the key to nanorod size. The researchers say it is the first study to identify the fundamenta ... more Chemists Create Two-Armed Nanorobotic Device 
New York NY (SPX) Feb 19, 2009Chemists at New York University and China's Nanjing University have developed a two-armed nanorobotic device that can manipulate molecules within a device built from DNA. The device is described in the latest issue of the journal Nature Nanotechnology. "The aim of nanotechnology is to put specific atomic and molecular species where we want them and when we want them there," said NYU ... more Nanoparticle Toxicity Doesn't Get Wacky At The Smallest Sizes 
Chicago IL (SPX) Feb 18, 2009The smallest nano-sized silica particles used in biomedicine and engineering likely won't cause unexpected biological responses due to their size. The result should allay fears that cells and tissues will react unpredictably when exposed to the finest silica nanomaterials in industrial or commercial applications. Nanotoxicologist Brian Thrall and colleagues found that, mostly, size doesn't ... more Scientists Prove Graphene's Edge Structure Affects Electronic Properties 
Champaign IL (SPX) Feb 18, 2009Graphene, a single-atom-thick sheet of carbon, holds remarkable promise for future nanoelectronics applications. Whether graphene actually cuts it in industry, however, depends upon how graphene is cut, say researchers at the University of Illinois. Graphene consists of a hexagonal lattice of carbon atoms. While scientists have predicted that the orientation of atoms along the edges of the ... more |

Semiconducting Nanotubes Produced In Quantity
Durham NC (SPX) Jan 23, 2009After announcing last April a method for growing exceptionally long, straight, numerous and well-aligned carbon cylinders only a few atoms thick, a Duke University-led team of chemists has now modified that process to create exclusively semiconducting versions of these single-walled carbon nanotubes. The achievement paves the way for manufacturing reliable electronic nanocircuits at the ... more Nanotech In Your Vitamins 
Washington DC (SPX) Jan 21, 2009The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency's lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN). The report, A Hard Pill To Swallow: Barriers ... more Easy Assembly Of Electronic Biological Chips 
University Park PA (SPX) Jan 20, 2009A handheld, ultra-portable device that can recognize and immediately report on a wide variety of environmental or medical compounds may eventually be possible, using a method that incorporates a mixture of biologically tagged nanowires onto integrated circuit chips, according to Penn State researchers. "Probably one of the most important things for connecting to the circuit is to place the ... more Nanoparticles Used To Make 3-D DNA Nanotubes 
Tuscon AZ (SPX) Jan 04, 2009Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential. In the January 2, 2009 issue of Science, Yan and Liu, researchers at ASU's Biodesign Institute and faculty in the Department of ... more |
