Terahertz invisibility cloak created
EVANSTON, Ill. – A new cloaking material can render objects invisible in the terahertz range. While the design does not create an invisibility cloak for the visible spectrum, it could have applications in diagnostics, security and communications. The cloak, created at Northwestern University, uses microfabricated gradient-index materials to manipulate the reflection and refraction of terahertz wavelengths. To render an object invisible, light must be manipulated so that it will neither scatter at an...
‘Campfire Effect’ Observed in Blinking Nanorod Clusters
PHILADELPHIA, June 30, 2011 — When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern, but when clustered together, the combined “on” time is increased dramatically, providing new insight into the mysterious blinking behavior. Many...
Pen ‘Writes’ Circuits for Flexible Electronics
CHAMPAIGN, Ill., June 30, 2011 — A pen with conductive silver ink that can write electrical circuits and interconnects on paper, wood and other surfaces is composing a whole new chapter in low-cost, flexible and disposable electronics. “Pen-based printing allows one to...
Synchrotron Imaging Shows How Folds Affect Graphene
BUFFALO, N.Y., June 30, 2011 — Synchrotron light sources have revealed electron clouds on the surface of graphene, showing how folds and ripples in the material can harm its conductivity. The research, scheduled to appear June 28 in Nature Communications, was conducted by...
AFM Forum to Focus on Materials, Life Sciences
ZURICH, Switzerland, June 29, 2011 — Swiss Federal Institute of Technology (ETH Zürich), Atomic Force F&E GmbH and Asylum Research have announced the third Euro AFM Forum. The atomic force microscopy event will be held in Zurich from Sept. 7 to 9 at Science City on ETH...
ALICE to Accelerate Bioresearch
CHESHIRE, England, June 29, 2011 — Low-power terahertz rays have proven applications in both security devices and medical imaging, but now the effects of Europe’s most intense terahertz light source on human cells is being researched with the hope of triggering advances in...
ISSAC Captures First Images
ROCHESTER, N.Y., June 29, 2011 — The multispectral imager ISSAC (International Space Station Agricultural Camera) successfully captured its first high-resolution image from space, imaging the western coast of Florida on June 10 from 250 miles above the Earth.
Optical Circuit Enables New Quantum Tech Approach
BRISTOL, England, June 29, 2011 — A fundamental building block for quantum computing that could soon be employed in a range of quantum technologies has been demonstrated. This quantum logic gate, acting on four photons, could lead to secure communications, precision measurement and...
Tiny Ring Laser Detects, Counts Nanoparticles
ST. LOUIS, June 29, 2011 — A tiny doughnut-shaped laser is the latest marvel of silicon microminiaturization, but instead of manipulating bits, it detects very small particles. Small particles play a big — and largely unnoticed — role in our everyday lives. Virus...
Full-Spectrum Solar Cell Created
TORONTO, June 28, 2011 — The first efficient tandem solar cell based on colloidal quantum dots (CQD) was reported at the University of Toronto, which said it may pave the way to inexpensive coatings that convert the sun's rays to electricity.
HD Tech Could Get Big Boost from Little Shrimp
PHILADELPHIA, June 28, 2011 — A two-part man-made waveplate inspired by the eye of the peacock mantis shrimp could improve CD, DVD, Blu-ray and holographic technology, creating even higher definition and larger storage density.
Lasers Generate Pure Microwave Signals
GAITHERSBURG, Md., June 28, 2011 — A new low-noise oscillator is generating microwave signals more pure and stable than those from conventional electronic sources. The apparatus could improve signal stability and resolution in radar, communications and navigation systems, and in...
New Method Images Molecules Inside Cells
GOTHENBURG, Sweden, June 28, 2011 — Using a novel sample holder, researchers at the University of Gothenburg have further developed a new method for imaging individual cells. This makes it possible to produce snapshots that show not only the outline of a cell but also the various...
Birds See More Colors Than They Wear
NEW HAVEN, Conn., June 27, 2011 — The brilliant colors of birds have inspired poets and nature lovers, but researchers at Yale University and the University of Cambridge in the UK say that these existing hues represent only a fraction of what birds can actually see. Findings...
Graphene Photodetectors Boost Data Speed
VIENNA, Austria, June 27, 2011 — Scientists at Vienna University of Technology (TU Vienna) have developed light detectors composed of graphene, demonstrating how remarkably fast the material converts light pulses into electrical signals, a capability that could considerably improve...
Wildfire Threatens Los Alamos National Lab
LOS ALAMOS, N.M., June 27, 2011 — A wind-driven wildfire is threatening Los Alamos National Laboratory, home to the Trident laser, the Roadrunner supercomputer and many National Nuclear Security Administration weapons programs.
Inspired Chaos in a Microlaser
WÜRZBURG, Germany, June 24, 2011 — Using a mirror to continually send a fraction of the emitted light back into a quantum dot microlaser, researchers were able to throw the light emission process off-kilter, prompting the microlaser to emit photons in a chaotic pulse sequence. This...
A Better Solar-Powered Water Splitter Devised
STANFORD, Calif., June 23, 2011 — To withstand the highly corrosive environment inherent in the process of splitting water, electron-producing silicon-based solar electrodes, which deteriorate almost immediately when exposed to oxygen, are now being coated with an ultrathin layer of...
Optical Amplifier Breaks Low-Noise Record
GOTHENBURG, Sweden, June 23, 2011 — An optical amplifier that can amplify light with extremely low noise has been demonstrated at Chalmers University of Technology. The new amplifier enables a reach increase for optical fiber signals from, for example, 1000 to 4000 km. This could lead...
Voyager 1 Nears the Final Frontier
LAUREL, Md., June 23, 2011 — By the time 2012 comes to a close, NASA’s Voyager 1 spacecraft may finally reach humanity’s last frontier: interstellar space. Cruising through space some 10.8 billion miles from the sun, Voyager 1 has crossed into an area where...
Black Hole Devours Star, Blasts Light Beam at Earth
COVENTRY, England, June 22, 2011 — The flash from one of the biggest and brightest bangs yet recorded originated with a massive black hole at the center of a distant galaxy that appears to have ripped apart a star that wandered too close. Some 3.8 billion years later, astronomers at...
Compact Microspectrometer Achieves High Resolution, Wide Bandwidth
ATLANTA, June 22, 2011 — A new microspectrometer architecture that uses compact disk-shaped resonators could address the challenges of integrated lab-on-chip sensing systems that now require a large off-chip spectrometer to achieve high resolution. Spectrometers have...
Smaller, Flexible LED Created
CORAL GABLES, Fla., June 22, 2011 — A new LED device has been created that uses an array of LEDs 100 times smaller than conventional LEDs and that is flexible, maintains lower temperature and has an increased life span. "The new model uses a silicon substrate, novel etching...
