First metallic nanoparticles resistant to extreme heat (12/1/2009)

A University of Pittsburgh team overcame a major hurdle plaguing the development of nanomaterials such as those that could lead to more efficient catalysts used to produce hydrogen and render car exhaust less toxic. The researchers reported Nov. 29 in Nature Materials the first demonstration of high-temperature stability in metallic nanoparticles, the vaunted next-generation materials hampered by a vulnerability to extreme heat. ...> Full Article

Nanotech in space: Rensselaer experiment to weather the trials of orbit (11/16/2009)

Novel 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 US Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. The materials will be mounted to the International Space Station's outer hull and exposed to the rigors of space. ...> Full Article

Where do nanomaterials go in the body? (11/5/2009)

Tiny, engineered nanomaterials can already be found in many consumer products, and have been hailed as having widespread future uses in areas ranging from medicine to industrial processes. However, little is known about what happens if these nanomaterials get into your body -- where do they go? NC State researchers are working to answer that question under a grant from the National Institutes of Health. ...> Full Article

Scientists bend nanowires into 2-D and 3-D structures (10/22/2009)

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. ...> Full Article

Nano-sandwich triggers novel electron behavior (5/8/2009)

A lattice of vanadium dioxide molecules just six atoms thick in which electrons appear to be guided by conflicting laws of physics depending on their direction of travel has been modeled by a team of physicists at the University of California, Davis. Its unique properties could open up a new world of possibilities in the emerging field of spintronics technology, which takes advantage of the magnetic as well as the electric properties of electrons in the design of novel electronic devices. ...> Full Article

Models present new view of nanoscale friction (2/26/2009)

Friction is a force that affects any application where moving parts come into contact; the more surface contact there is, the stronger the force. At the nanoscale -- mere billionths of a meter -- friction can wreak havoc on tiny devices made from only a small number of atoms or molecules. With their high surface-to-volume ratio, nanomaterials are especially susceptible to the forces of friction. ...> Full Article
