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. Source: Brookhaven

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
