Technique Expands Range of X-ray Research
ARGONNE, Ill., Aug. 20, 2012 — A new technique takes much of the “guesswork” out of x-ray imaging by combining high-resolution and 3-D viewing, allowing the surface of materials to be viewed nondestructively for the first time. The findings expand the range of x-ray research possible for biology, nanophotonics and nanoelectronics.
Color-Coded Markers Diagnose Disease Through Eyes
SAN DIEGO, Aug. 17, 2012 — New fluorescent probes that change color when they encounter brain disease markers found in the eye could offer a simpler way to identify neurodegenerative disease and distinguish between closely related disorders such as Parkinson’s, Alzheimer’s...

CORAL GABLES, Fla., Aug. 17, 2012 — Using UV light to switch fluorescent molecules on and off in aqueous environments could help scientists develop better fluorescent probes for biomedical research.
Nanocoating Keeps Solar Panels Clean
HOUSTON, Aug. 17, 2012 — A novel nanoparticle coating repels dust, pollen and other particles, and could keep solar panels clean and operating at their peak efficiency longer than conventional panels.
Future Light Component Produced in Printing Press
UMEÅ, Sweden, Aug. 16, 2012 — A new roll-to-roll compatible process can produce organic light-emitting electrochemical cells under ambient conditions, which could lead to large-area light-emitting devices used in informative displays, and, later, in lighting applications.
Metamaterial Moves Photons in Single Direction
CAMBRIDGE, Mass., Aug. 15, 2012 — A new metamaterial can channel photons in one direction, and could point the way to more efficient and faster computer chips that use light to move data.
Scalable Sapphire Seen as Superior to Silica for Fiber Optics
CLEMSON, S.C., Aug. 15, 2012 — Transforming scalable sapphire into a fiber that can withstand greater light intensity provides an easily accessible, low-cost solution for fiber optics using common materials.
First Full-Color Image at 100,000 dpi
SINGAPORE, Aug. 14, 2012 — A method of printing metal-laced, nanometer-sized structures has created full-color images at 100,000 dots per inch, revolutionizing the way images are printed. The technology could be further developed for high-resolution reflective color displays...
LHC Experiments Shed Light on Primordial Universe
GENEVA, Aug. 14, 2012 — The primordial particles of matter that existed just after the big bang are now being re-created in the Large Hadron Collider to advance understanding of the kind of matter that existed in the first seconds of the universe.
NASA Teams to Advance Small Spacecraft Technologies
WASHINGTON, Aug. 14, 2012 — Teams have been named to advance radio communications, formation flying and docking systems for NASA’s Small Spacecraft Technology Program.
Report Hails Photonics as Hope for US Economy
WASHINGTON, Aug. 14, 2012 — A national photonics initiative would not only advance the economy in the US but also enable growth in applications of optical science and technology, according to a new report from the US National Academy of Sciences that identifies research...
DARPA Seeks Ultrafast Laser Science Proposals
ARLINGTON, Va., Aug. 13, 2012 — DARPA is looking to fund projects to develop ultrafast laser applications including microwave generation, optical time transfer, laser-driven secondary radiation generation and attosecond science through its Pulse (Program in Ultrafast Laser Science...
Surprising Quantum Source Yields Info Advantage
SINGAPORE, Aug. 13, 2012 — Quantum entanglement may not always be necessary to run quantum computers, new research suggests. Moreover, technologies discovered over the past few years can gain a quantum advantage without entanglement.
X-Ray Beam Refined to Scalpel Precision
MENLO PARK, Calif., Aug. 13, 2012 — A thin sliver of diamond has transformed the Linac Coherent Light Source (LCLS) into a precise tool for studying and manipulating matter at the atomic level - and may enable experiments that have never before been possible.
For New Applications, Give Photonic Fiber a Twist
ERLANGEN, Germany, Aug. 10, 2012 — Simple longitudinal twists that convert photonic crystal fibers into filters were measured and theorized upon; the results suggest new applications in optical communications and will enable the construction of sensors, light amplifiers and lasers.
Sound Waves Focused Like A Camera Lens
UNIVERSITY PARK, Pa., Aug. 10, 2012 — A metamaterial capable for the first time of manipulating a variety of acoustic waves with one simple device was designed and computationally tested. The device holds promise for applications across various acoustic fields, from medical ultrasound...
System Simultaneously Uses Loss, Gain
ERLANGEN, Germany, Aug. 10, 2012 — Light absorption (loss), usually seen as a disadvantage in optical metamaterials, has been shown to have useful applications.
Process Could Make IR Lenses up to 70 Percent Cheaper
FREIBURG, Germany, Aug. 8, 2012, — A new fabrication process that lowers the cost of infrared lenses for thermal cameras by 70 percent could make such devices more attractive for integration into cars as driver warning systems.
Robotic Hand Gets Thumbs Up
SAARBRÜCKEN, Germany, Aug. 7, 2012 — The first human-sized, five-fingered robotic hand also has a brain: it has the cognitive power to learn to grasp and manipulate a range of delicate and oddly shaped objects just as humans do.
X-ray Imaging Shines Light on Gold Nanocrystals
LONDON, Aug. 7, 2012 — A new x-ray diffraction technique has revealed the three-dimensional shape of gold nanocrystals and is likely to shine a light on the structure of other nanoscale materials.
LZH to Push fs Pulse Energies into µJ Range
HANNOVER, Germany, Aug. 6, 2012 — The first 2-µm femtosecond laser source with pulse energies in the µJ range is under development and could lead to new fields of application in medical technology, micromaterial processing and nanotechnology.
Toward an ‘Unbreakable’ Message Exchange
WÜRZBURG, Germany, Aug. 6, 2012 — Single particles of light were produced and implemented into a quantum key distribution link, paving the way for unbreakable communication networks.
Chemical Sensor Seeks Out Land Mines, IEDs
STORRS, Conn., Aug. 3, 2012 — A new chemical sensing system that unearths land mines and other buried explosives by signaling their presence to the naked eye without advanced scientific instrumentation may be the first of its kind, University of Connecticut engineers say.
Making Microscale Wrinkles
CAMBRIDGE, Mass., Aug. 3, 2012 — A new method of creating microscale wrinkled surfaces with precise sizes and patterns can be compared to the way raisin skins dry, becoming stiff and wrinkly as the pulp inside dries out.
A Novel Approach to Negative Refraction
CAMBRIDGE, Mass., Aug. 2, 2012 — An “extraordinarily strong” negative refractive index as large as -700 - more than 100 times larger than most previously reported - was achieved in metamaterials using a new technique developed by scientists at the Harvard School of Engineering and...
