Dupont buys IP for Nanomaterial seen as Hot in Cosmetics, Coatings.
DuPont Titanium Technologies,  has closed an intellectual property agreement with NanoSource Technologies Inc., a nanomaterials company in Oklahoma City. NanoSource, had developed a prototype process for manufacturing titanium dioxide nanopowders, which are less than 100 nanometers in diameter.

Silicon nanoparticles eyed for chemical detection
A method for fabricating porous-silicon nanoparticles that have a selective response to light could lead to a fundamentally new capability for chemical sensing. Developed at the University of California, the process creates a special reflective layer — called a rugate filter — on the surface of the nanoparticles.

Conducting-Insulating Materials Reveal Their Secrets
Research by physicists at the U.S. Department of Energy’s Brookhaven National Laboratory provides new insight into why some materials made of stacks of metallic planes are conductors in the direction of the planes and are insulators in the direction perpendicular to the planes. Such behavior is in marked contradiction with scientists’ traditional understanding of metallic conductivity, where the electrical current is carried by electrons in every direction.

Breakthrough made in electronics Technology
Researchers at Oregon State University have made a significant breakthrough in the technology to produce crystalline oxide films, which play roles in semiconductor chips, flat panel displays and many other electronic products. In a report  published in the journal Science, the OSU scientists explain a way to create these crystalline thin films at temperatures far lower than those now used, and with no need to be produced in a vacuum as the current technology usually requires.

New Class of Composite Organic Material Could Put the Muscle in Artificial Body Parts
A new class of all organic composites that change shape under an electric voltage may open the door for the manufacture of artificial muscles, smart skins, capacitors, and tiny drug pumps, according to Penn State researchers.

Most Unusual Superconductor and How It Works  
First-principles calculation explains the strange behavior of magnesium diboride
Magnesium diboride (MgB2) becomes superconducting at 39 degrees Kelvin, one of the highest known transition temperatures (Tc) of any superconductor. What's more, its puzzling characteristics include more than one superconducting energy gap, a state of affairs anticipated in theory but never before seen experimentally.

Discovery could bring widespread uses for "nanocrystals"
Researchers at Purdue University have made a surprising discovery that could open up numerous applications for metal "nanocrystals", or tiny crystals that are often harder, stronger and more wear resistant than the same materials in bulk form
