Toughened silicon sponges may make tenacious batteries
Researchers at Rice University and Lockheed Martin reported this month that they've found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace graphite as an element in rechargeable lithium-ion batteries, laying the groundwork for longer-lasting, more powerful batteries for such applications as commercial electronics and electric vehicles.

Carbon-based transistors ramp up speed and memory for mobile devices
Elad Mentovich of Tel Aviv University's Center for Nanoscience and Nanotechnology says that, by using carbon molecules called C60 to build a sophisticated new memory transistor, he has found a way to increase both speed and memory on the devices -- and his solution is ready to be produced at existing high-tech fabrication facilities.

Gold nanoparticles could treat prostate cancer with fewer side effects than chemotherapy
University of Missouri scientists have found a more efficient way of targeting prostate tumors by using gold nanoparticles and a compound found in tea leaves. This new treatment would require doses that are thousands of times smaller than chemotherapy and do not travel through the body inflicting damage to healthy areas.

Unique properties of graphene lead to a new paradigm for low-power telecommunications
Columbia engineers have demonstrated remarkable optical nonlinear behavior of graphene that may lead to broad applications in optical interconnects and low-power photonic integrated circuits. Tthe researchers used graphene to transform the originally passive device into an active one that generated microwave photonic signals and performed parametric wavelength conversion at telecommunication wavelengths. Showing the power-efficiency of the device, they say, is an important advance in building all-optical processing elements essential to faster, more efficient, modern telecommunications.

UMD creates new tech for complex micro structures for use in sensors & other apps
University of Maryland Chemistry Professor John Fourkas and his research group have developed new materials and nanofabrication techniques for building miniaturized versions of components needed for medical diagnostics, sensors and other applications. These miniaturized components -- many impossible to make with conventional techniques -- would allow for rapid analysis at lower cost and with small sample volumes.

Making 'renewable' viable
A team of researchers from Drexel University's College of Engineering has developed a new method for quickly and efficiently storing and discharging large amounts of energy. Their "electrochemical flow capacitor," which is fully scalable, could be the key to a more efficient integration of renewable resources into the energy grid.

Ions, not particles, make silver toxic to bacteria
Rice researchers settle a long-standing controversy on the mechanism by which silver nanoparticles kill bacteria – and they find that using too little can help bacteria build immunity.

UK nanodevice builds electricity from tiny pieces
A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump – a nano-device –, which picks these electrons up one at a time and moves them across a barrier, creating a very well-defined electrical current.

Smart materials get SMARTer
Living organisms have developed sophisticated ways to maintain stability in a changing environment, withstanding fluctuations in temperature, pH, pressure, and the presence or absence of crucial molecules. The integration of similar features in artificial materials, however, has remained a challenge -- until now.

Imagine a white luminous curtain waving in the breeze. Or wallpaper that lights up your room with perfect white light. The applications are not very far away. White LEDs, made from zinc oxide and a conducting polymer, can be manufactured directly on paper, as shown by Gul Amin in his doctoral thesis at Linköping University, Sweden.

Metamolecules that switch handedness at light-speed
A multi-institutional team of researchers that included Berkeley Lab scientists has created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially huge possibilities for the application of terahertz technologies across a wide range of fields, including biomedical research, homeland security and ultrahigh-speed communications.

Tiny bubbles snap carbon nanotubes like twigs
A computer model from Rice University shows that long nanotubes bend and snap like a twig when blasted with ultrasonic energy. The research in the Proceedings of the National Academy of Sciences finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.
