MIT researcher sees big impact of little cracks
An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake. view more (2006-01-19)
New nanocomposites may mean more durable tooth fillings
The mouth is a tough environment-which is why dentists do not give lifetime guarantees. Despite their best efforts, a filling may eventually crack under the stress of biting, chewing and teeth grinding, or secondary decay may develop where the filling binds to the tooth. view more (2007-04-30)
Caltech scientists create nanoscale zipper cavity that responds to single photons of light
Physicists at the California Institute of Technology (Caltech) have developed a nanoscale device that can be used for force detection, optical communication, and more. view more (2009-06-08)
New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms vibrate in high definition in real time. view more (2007-03-19)
Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers. view more (2007-07-13)
Bridging the gap in nanoantennas
In a recent publication in Nature Photonics, a joint team of researchers at CIC nanoGUNE, Donostia International Physics Center DIPC, Centro de Física de Materiales of CSIC/UPV-EHU in San Sebastian (Spain), Harvard University (USA) and the Max Planck Institute of Biochemistry in Munich (Germany) reports an innovative method for controlling light... view more...

Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small. view more (2006-07-17)
ORNL super water repellent could cause big wave in market
A water repellent developed by researchers at the Department of Energy's Oak Ridge National Laboratory outperforms nature at its best and could open a floodgate of commercial possibilities. view more (2007-11-30)
Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures. view more (2007-03-12)
Molecular spintronic action confirmed in nanostructure
Researchers at the National Institute of Standards and Technology (NIST) have made the first confirmed "spintronic" device incorporating organic molecules, a potentially superior approach for innovative electronics that rely on the spin, and associated magnetic orientation, of electrons. view more (2006-10-13)
All done with mirrors: NIST microscope tracks nanoparticles in 3-D
A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions. view more (2008-03-11)
Bacteria and nanofilters - the future of clean water technology
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology. view more (2008-02-25)
Secret Lives of Catalysts Revealed
The first-ever glimpse of nanoscale catalysts in action could lead to improved pollution control and fuel cell technologies. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed catalysts restructuring themselves in response to various gases swirling around them, like a chameleon changing its color to... view more...

University of Pennsylvania engineers discover natural 'workbench' for nanoscale construction
Engineers at the University of Pennsylvania have taken a step toward simplifying the creation of nanostructures by identifying the first inorganic material to phase separate with near-perfect order at the nanometer scale. view more (2007-07-18)
Cheaper LEDs from breakthrough in zinc oxide (ZnO) nanowire research, Nano Letters study says
Engineers at UC San Diego have synthesized a long-sought semiconducting material that may pave the way for an inexpensive new kind of light emitting diode (LED) that could compete with today's widely used gallium nitride LEDs, according to a new paper in the journal Nano Letters. view more (2007-01-04)
A new window into the deformation of nanoscale materials
Materials on the nanoscale don't always have the same properties they would in bulk; for one thing, nanomaterials are often a lot harder. Unlike most bulk materials, a crystal that is small enough can be perfect, free of defects, capable of achieving strength near its ideal theoretical limit. view more (2006-08-14)
More Than Meets the Eye: New Blue Light Nanocrystals
Berkeley Lab researchers have produced non-toxic magnesium oxide nanocrystals that efficiently emit blue light and could also play a role in long-term storage of carbon dioxide, a potential means of tempering the effects of global warming. view more (2009-07-22)
The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. view more (2008-06-25)
Carbon nanotubes could make efficient solar cells
Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. view more (2009-09-11)
U-M research: New plastic is strong as steel, transparent
By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent. view more (2007-10-05)
