New material could improve fabrication of nanoscale components
A team of chemists at Penn State has developed a new type of ultrathin film, which has unusual properties that could improve the fabrication of increasingly smaller and more intricate electronic and sensing devices. The material, a single layer made from spherical cages of carbon atoms, could enable more precise patterning of such devices with a wider range of molecular components than now is possible with conventional self-assembled monolayers.
'Smart' nanoprobes light up disease
Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. Altered expression of particular proteases is a common hallmark of cancer, atherosclerosis, and many other diseases.
Engineers point way to better use of nanotubes as measuring tips
Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called "multi-walled carbon nanotubes" to more precisely measure structures and devices for electronics and other applications.
Ways to turn manure into power
Record oil prices and incentives to find alternative fuel sources are lighting a fire under research to turn biomass materials such as manure into energy.
A new spin on silicon
For about 40 years, the semiconductor industry has been able to continually shrink the electronic components on silicon chips, packing ever more performance into computers. Now, fundamental physical limits to current technology have the industry scouring the research world for an alternative

Charges to go
Cell phone charged? Joe Hynek and his Iowa State University collaborators are working to make wearable solar charging devices useful and pretty
A 'rinse' for washing machines that dries clothes
Think of it as a kind of chemical clothes wringer. University of Florida engineers have developed a compound that forces clothes in the washer to shed 20 percent more water during the spin cycle than in normal conditions. The result: A load of clothes dries faster in the dryer, saving energy — and reducing homeowners' electricity bills and time spent in the laundry room
First large scale evaluation of iris recognition under way
The National Institute of Standards and Technology (NIST) has announced that it is running the Iris Challenge Evaluation (ICE), the first large-scale evaluation of iris recognition
Research needed to improve solar energy technologies
To help achieve the Bush Administration's goal of increased use of solar and other renewable forms of energy, the Department of Energy's (DOE) Office of Science has released a report describing the basic research needed to produce "revolutionary progress in bringing solar energy to its full potential in the energy marketplace." The report resulted from a workshop of 200 scientists held earlier this year

Scientists harness the power of pee
Physicists in Singapore have succeeded in creating the first paper battery that generates electricity from urine. This new battery will be the perfect power source for cheap, disposable healthcare test-kits for diseases such as diabetes
New microprinting technique improves nanoscale fabrication
Scientists will announce next month a new technique called microdisplacement printing, which makes possible the highly precise placement of molecules during the fabrication of nanoscale components for electronic and sensing devices.
Strong, transparent carbon nanotube sheets
University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays, low-noise electronic sensors, artificial muscles, conducting appliqués and broad-band polarized light sources that can be switched in one ten-thousandths of a second.
Airbone drones, mimicking gulls, alter wing shape for agility
The military's next generation of airborne drones won't be just small and silent – they'll also dive between buildings, zoom under overpasses and land on apartment balconies.
Modified collagen could yield important medical applications
Collagen often pops up in beauty products and supermodel lips. But by mating collagen with a molecular hitchhiker, materials scientists at Johns Hopkins hope to create some important medical advances.
New method to drive fuel cells for portable electronics
Engineers at Purdue University have developed a new way of producing hydrogen for fuel cells to automatically recharge batteries in portable electronics, such as notebook computers, and eliminate the need to use a wall outlet.
Tiny rubber balls give plastic bounce
Automobile bumpers that deform and recover rather than crack and splinter, computer cases that withstand the occasional rough encounter, and resilient coatings that can withstand the ravages of the sun, may all be possible if tiny functionalized rubbery particles are imbedded in their plastic matrices, according to Penn State materials scientists.
New diamond-nanotube composite material
Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material – diamond – with the world's strongest structural form – carbon nanotubes. This new process for "growing" diamond and carbon nanotubes together opens the way for its use in a number of energy-related applications.
Short-term bio sensors monitor from afar
A temporary under-the-skin sensor could monitor a variety of health indicators for soldiers, athletes, diabetics, infants, and critically ill patients without wires and at a distance, according to a team of Penn State chemical engineers.
Researchers find new mechanism governing particle growth in nanocomposites
Because the properties of nanoparticles depend so closely on their size, size distribution and morphology, techniques for controlling the growth of these tiny structures is of great interest to materials researchers today.
