NIST scientists use electron beam to unravel the secrets of an 'atomic switch'
Scientists at the Commerce Department's National Institute of Standards and Technology (NIST) have used a beam of electrons to move a single atom in a small molecule back and forth between two positions on a crystal surface, a significant step toward learning how to build an "atomic switch" that turns electrical signals on and off in... view more...

Nano-cages 'fill up' with hydrogen
A "cagey" strategy to stack more hydrogen in nanoscale scaffoldings made of zinc-based boxes may yield a viable approach to storing hydrogen and, ultimately, replacing fossil fuels in future automobiles, according to new results from National Institute of Standards and Technology (NIST) researchers. view more (2005-12-02)
FDA Nanotechnology Task Force takes positive step forward
Today's report from the Food and Drug Administration (FDA) Nanotechnology Task Force is an important and positive step forward in the agency's effort to tackle the new scientific and regulatory challenges posed by nanotechnology. view more (2007-07-26)
Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or instead of their charge. One thing spinning... view more... (2007-02-16)
What makes Mars magnetic?
Earth's surface is a very active place; its plates are forever jiggling around, rearranging themselves into new configurations. Continents collide and mountains arise, oceans slide beneath continents and volcanoes spew. view more (2007-08-13)
Nanotech Research Featured in Nature Nanotechnology Journal

Harvard scientists bend nanowires into 2-D and 3-D structures
Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. view more (2009-10-22)
Traces of nanobubbles determine nanoboiling
Using a microscope and some extreme "snapshot" photography with shutter speeds only a few nanoseconds long, researchers from the National Institute of Standards and Technology (NIST) and Cornell University have uncovered the traces of ephemeral "nanobubbles" formed in boiling water on a microheater. view more (2007-04-02)

Of the 92 naturally occurring elements, add another to the list of those that are superconductors. view more (2009-05-18)
Spallation Neutron Source gets initial go-ahead on second target
The U.S. Department of Energy has given its initial approval to begin plans for a second target station for the Spallation Neutron Source, expanding what is already the world's most powerful pulsed neutron scattering facility located at DOE's Oak Ridge National Laboratory. view more (2009-01-20)
Terahertz waves are effective probes for IC heat barriers
By modifying a commonly used commercial infrared spectrometer to allow operation at long-wave terahertz frequencies, researchers at the National Institute of Standards and Technology (NIST) discovered an efficient new approach to measure key structural properties of nanoscale metal-oxide films used in high-speed integrated circuits. view more (2009-05-11)
Measurements from the edge: magnetic properties of thin films
Materials researchers at the National Institute of Standards and Technology (NIST), together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge-literally-to produce the first data on how the edges of metallic thin films contribute to their magnetic properties. view more (2007-10-01)
Physicists pin down spin of surface atoms
Scientists who dream of shrinking computers to the nanoscale look to atomic spin as one possible building block for both processor and memory, yet setting the spin of an atom, let alone measuring it, has been a challenge. view more (2007-09-13)
Lava flows reveal clues to magnetic field reversals
Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field - and what may drive it to occasionally reverse direction. view more (2008-09-29)
NIST team develops novel method for nanostructured polymer thin films
All researchers at the National Institute of Standards and Technology (NIST) wanted was a simple, quick method for making thin films of block copolymers or BCPs (chemically distinct polymers linked together) in order to have decent samples for taking measurements important to the microelectronics industry. view more (2007-09-17)
Scientists get new facility to study materials
A new scientific research instrument on the Isis Facility at the CLRC Rutherford Appleton Laboratory was officially inaugurated today, Friday 6 October. The Osiris spectrometer will provide scientists with the unrivalled combination of a spectrometer and a diffractometer in the same instrument. Using this they will be able to measure where the... view more... (2000-10-06)
