When a good nanoparticle goes bad
Researchers at Cornell University recently made a major breakthrough when they invented a method to test and demonstrate a long-held hypothesis that some very, very small metal particles work much better than others in various chemical processes such as converting chemical energy to electricity in fuel cells or reducing automobile pollution. view more (2008-11-11)
Hydrogen sensors are faster, more sensitive
Hydrogen sensor technology is a critical component for safety and other practical concerns in the proposed hydrogen economy. For example, hydrogen sensors will detect leaks from hydrogen powered cars and fueling stations long before the gas becomes an explosive hazard. view more (2005-05-26)
Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
Scientists reveal DNA-enzyme interaction with first ever real time footage
For the first time scientists have been able to film, in real-time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. view more (2007-09-18)
Goddard-Led GEMS Mission to Explore the Polarized Universe
An exciting new astrophysics mission led by NASA's Goddard Space Flight Center in Greenbelt, Md., will provide a revolutionary window into the universe. Named the Gravity and Extreme Magnetism Small Explorer (GEMS), the satellite will be the first to systematically measure the polarization of cosmic X-ray sources. view more (2009-08-05)
Caltech scientists solve decade-long mystery of nanopillar formations
Scientists at the California Institute of Technology (Caltech) have uncovered the physical mechanism by which arrays of nanoscale (billionths-of-a-meter) pillars can be grown on polymer films with very high precision, in potentially limitless patterns. view more (2009-10-23)
Nanoscientists Provide New Picture of Semiconductor Material
For almost a decade, scientists thought they understood the surface structure of cubic gallium nitride, a promising new crystalline semiconductor. view more (2005-10-05)
Argonne researcher studies what makes quantum dots blink
In order to learn more about the origins of quantum dot blinking, researchers from the U.S. Department of Energy's Argonne National Laboratory, the University of Chicago and the California Institute of Technology have developed a method to characterize it on faster time scales than have previously been accessed. view more (2007-10-05)
Fluid Dynamics Works on Nanoscale in Real World
In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too - that is, outside of a vacuum. The results appear in the February 9 issue of Physical Review Letters (PRL). view more (2007-02-26)
Public Shares Views on Environmental, Health, and Safety Research Needs for Engineered Nanoscale Materials
Approximately 150 people took part in the National Nanotechnology Initiative's (NNI) Public Meeting on Research Needs related to the Environmental, Health, and Safety Aspects of Engineered Nanoscale Materials. The meeting was held January 4, 2007, in Arlington, Virginia. view more (2007-01-10)
A special issue on the International Workshop of the 2008 Solar Total Eclipse
On August 1, 2008 a total solar eclipse was visible within a narrow corridor that traversed from North America to China. view more (2009-11-02)
A snapshot of the transformation
Researchers have achieved a milestone in materials science and electron microscopy by taking a high-resolution snapshot of the transformation of nanoscale structures. view more (2008-09-12)
Researchers Discover a Potential On-Off Switch for Nanoelectronics
As electronic circuits shrink from finely etched lines in silicon wafers to nearly elusive proportions, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Columbia University are studying how electrons flow through a molecular junction-a nanometer scale circuit element that contacts gold atoms... view more...

Quantum Device Traps, Detects and Manipulates the Spin of Single Electrons
A novel device, developed by a team led by University at Buffalo engineers, simply and conveniently traps, detects and manipulates the single spin of an electron, overcoming some major obstacles that have prevented progress toward spintronics and spin-based quantum computing. view more (2007-09-28)
Water flows like molasses on the nanoscale
A Georgia Tech research team has discovered that water exhibits very different properties when it is confined to channels less than two nanometers wide - behaving much like a viscous fluid with a viscosity approaching that of molasses. view more (2007-04-25)
Researchers create new nanotechnology field
A University of Alberta research team has combined two fields of study in nanotechnology to create a third field that the researchers believe will lead to revolutionary advances in computer electronics, among many other areas. view more (2007-05-31)
Plasmonic Whispering Gallery Microcavity Paves the Way to Future Nanolasers
The principle behind whispering galleries - where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber - has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultrasmall lasers, i.e., nanoscale, promise a wide variety of intriguing... view more... (2009-01-26)
ASU researchers improve memory devices using nanotech
Arizona State University's Center for Applied Nanoionics (CANi) has a new take on old memory, one that promises to boost the performance, capacity and battery life of consumer electronics from digital cameras to laptops. Best of all, it is cheap, made from common materials and compatible with just about anything currently on the market. view more (2007-10-24)
Scientists demonstrate method for integrating nanowire devices directly onto silicon
Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. view more (2008-05-09)
