Nano For The Senses And Much More At Nano Tech 2010 Tokyo, Japan (SPX) Feb 04, 2010 
A mystical glow emanates from the display case. A white light appears out of nowhere. And a light source is invisible - at least at first glance. Only upon close examination does the source of the apparently supernatural illumination become visible: a light diode, smaller than a pinhead, passes through thousands of infinitesimal lens structures measuring only a few hundred nanometers, et voilą: ... read moreExploring Phase Transistions At The Nano Level 
Seattle WA (SPX) Feb 03, 2010Phase transitions - changes of matter from one state to another without altering its chemical makeup - are an important part of life in our three-dimensional world. Water falls to the ground as snow, melts to a liquid and eventually vaporizes back to the clouds to begin the cycle anew. Now a team of scientists has devised a new way to explore how such phase transitions function in less tha ... more

Science seeks to control the Casimir force
Argonne, Ill. (UPI) Dec 10, 2009 U.S. scientists say they are seeking a way of controlling the Casimir force -- a quantum mechanical force that hampers creation of nanoscale machines. Researchers at the Department of Energy's Argonne National Laboratory said the Casimir force, which attracts objects when they are only 100 nanometers apart, is so small most experimentation has only dealt with its characteristics. ... more Nanotech Experiment To Weather The Trials Of Orbit 
Troy NY (SPX) Nov 18, 2009Novel nanomaterials developed at Rensselaer Polytechnic Institute are scheduled to blast off into orbit on November 16 aboard Space Shuttle Atlantis. The project, funded by the U.S. Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. Space Shuttle Atlantis will carry the samples to the International Space Station (ISS). T ... more Better Control Of Carbon Nanotube Growth Promising For Future Electronics 
West Lafayette IN (SPX) Oct 02, 2009Researchers have overcome a major obstacle in efforts to use tiny structures called carbon nanotubes to create a new class of electronics that would be faster and smaller than conventional silicon-based transistors. Carbon nanotubes, which were discovered in the early 1990s, could make possible more powerful, compact and energy-efficient computers, as well as ultra-thin "nanowires" for ... more Theoretical Electrical Resistance Discovery Proven In Nanomaterials Lab 
Lincoln NE (SPX) Sep 23, 2009Does theory lead experiments or do experiments lead theory? Scientists know the correct answer is that interplay between theory and experiments result in new advances. At times, experiment and technological development pave the way for theory. At other times, successful theory can contribute substantially to interpretation and analysis of the experimental data. But even more important is ... more |

Carbon Nanotubes Are Superior To Metals For Electronics
Buffalo NY (SPX) Mar 27, 2009 In 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 |
