Tiny antennas let long light waves see in infrared
University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared spectrum. The semiconductor antenna arrays allow long-wavelength light to strongly interact with nano-scale substances, so the arrays could enhance the detection of small volumes of materials.

With carbon nanotubes, a path to flexible, low-cost sensors
Researchers at the Technische Universitaet Muenchen are showing the way toward low-cost, industrial-scale manufacturing of a new family of electronic devices. A leading example is a gas sensor that could be integrated into food packaging to gauge freshness, or into compact wireless air-quality monitors. Flexible pressure and temperature sensors could be built into electronic skin. All these devices can be made with carbon nanotubes, sprayed like ink onto flexible plastic sheets or other substrates.

New multifunctional topological insulator material with combined superconductivity
By employing state-of-art materials design methods, Dr. Binghai Yan and his collaborators from the Max Planck Institute for Chemical Physics of Solids and Mainz University have recently predicted that the oxide compound BaBiO3 combines two required properties, i.e., topological insulator and superconductivity. This material has been known as a high-temperature superconductor of Tc of nearly 30 Kelvin with p-type doping. Now it has been discovered to be also a topological insulator with n-type doping.

A first: Stanford engineers build computer using carbon nanotube technology
Silicon chips could soon hit physical limits preventing them from getting smaller and faster. Carbon nanotube technology has been seen as a potential successor. But so far no one's been able to put all the pieces together. Stanford's CNT computer is therefore an important proof of principle. And while this is a bare-bones device, the processes used to create the world's first CNT computer are designed to scale.

Fusion, anyone?
The dream of igniting a self-sustained fusion reaction with high yields of energy, a feat likened to creating a miniature star on Earth, is getting closer to becoming reality, according the authors of a new review article in the journal Physics of Plasmas.

Spinning CDs to clean sewage water
Audio CDs, all the rage in the '90s, seem increasingly obsolete in a world of MP3 files and iPods, leaving many music lovers with the question of what to do with their extensive compact disk collections. While you could turn your old disks into a work of avant-garde art, researchers in Taiwan have come up with a more practical application: breaking down sewage.

UCSB researchers make headway in quantum information transfer via nanomechanical coupling
Fiber optics has made communication faster than ever, but the next step involves a quantum leap –– literally. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications.

Stanford scientists publish theory, formula to improve 'plastic' semiconductors
We could find many uses for bendable electronics, such as e-readers that folded like newspapers or smart phones that curved in our back pockets. Polymer semiconductors could get us there. But their electrical properties are not well understood. In some novel work Stanford scientists explain how the structure of polymers affects their electrical properties with an eye toward improving their performance as electronic components.

Putting the spring back in broken hearts
For years, scientists have been trying to engineer cardiac tissue to patch up areas of the heart damaged by heart attacks. Now Tel Aviv University researchers have fabricated fibers shaped like springs that allow engineered cardiac tissue to pump more like the real thing. They say that, once tested in clinical trials, the use of these fibers will improve and prolong the lives of millions of people.

Densest array of carbon nanotubes grown to date
Carbon nanotubes' outstanding mechanical, electrical and thermal properties make them an alluring material to electronics manufacturers. However, until recently scientists believed that growing the high density of tiny graphene cylinders needed for many microelectronics applications would be difficult. Now a team from Cambridge University in England has devised a simple technique to increase the density of nanotube forests grown on conductive supports about five times over previous methods.

Promising new alloy for resistive switching memory
Memory based on electrically-induced "resistive switching" effects have generated a great deal of interest among engineers searching for faster and smaller devices because resistive switching would allow for a higher memory density. Researchers have tested a number of oxide materials for their promise in resistive switching memories, and now a team of researchers in Singapore have demonstrated how conductive nano-filaments in amorphous titanium dioxide thin films could be utilized for resistive switching device applications.

Container's material properties affect the viscosity of water at the nanoscale

UCLA researchers' smartphone 'microscope' can detect a single virus, nanoparticles
Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Aydogan Ozcan, a UCLA professor of engineering, has created a portable smartphone attachment to enable sophisticated field testing of fluid and solid samples for detection of viruses and bacteria without need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.
