Light Twists Rigid Structures In Unexpected Ways Ann Arbor MI (SPX) Mar 19, 2010 
In findings that took the experimenters three years to believe, University of Michigan engineers and their collaborators have demonstrated that light itself can twist ribbons of nanoparticles.
The results are published in the current edition of Science.
Matter readily bends and twists light. That's the mechanism behind optical lenses and polarizing 3-D movie glasses. But the opposite inte ... read moreSuperconductors On The Nanoscale 
Princeton NJ (SPX) Mar 16, 2010Superconductors, materials in which current flows without resistance, have tantalizing applications. But even the highest-temperature superconductors require extreme cooling before the effect kicks in, so researchers want to know when and how superconductivity comes about in order to coax it into existence at room temperature. Now a team has shown that, in a copper-based superconductor, ti ... more

A New Way Of Producing Electricity With Nanotubes
Cambridge MA (SPX) Mar 11, 2010A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say. The phenomenon, described as thermopower waves, "opens up a new area of energy research, which is rare," says Michael Strano, MIT's ... more Graphene Nanomesh Could Change The Future Of Electronics 
Los Angeles CA (SPX) Mar 01, 2010Graphene, a one-atom-thick layer of a carbon lattice with a honeycomb structure, has great potential for use in radios, computers, phones and other electronic devices. But applications have been stymied because the semi-metallic graphene, which has a zero band gap, does not function effectively as a semiconductor to amplify or switch electronic signals. While cutting graphene sheets into n ... more Trapping Sunlight With Silicon Nanowires 
Berkeley CA (SPX) Mar 08, 2010Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20 percent efficiencies, the cost of this solar power is prohibitive for large-scale use. Researchers with the Lawrence Berkele ... more Atmospheric Nanoparticles Can Impact Health And Weather 
College Station TX (SPX) Mar 05, 2010Nanoparticles are atmospheric materials so small that they can't be seen with the naked eye, but they can very visibly affect both weather patterns and human health all over the world - and not in a good way, according to a study by a team of researchers at Texas A and M University. Researchers Renyi Zhang, Alexei Khalizov, Jun Zheng, Wen Xu, Yan Ma and Vinita Lal in the Departments of Atm ... more |

New Fiber Nanogenerators Could Lead To Electric Clothing
Berkeley CA (SPX) Feb 16, 2010In research that gives literal meaning to the term "power suit," University of California, Berkeley, engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles. These nano-sized generators have "piezoelectric" properties that allow them to convert into electricity the energy created through mechanical stress, stretches and twists. "This ... more Nano For The Senses And Much More At Nano Tech 2010 
Tokyo, Japan (SPX) Feb 04, 2010A 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: ... more Exploring 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 |
