Samsung to Mass Produce Highly Interactive Displays
SEOUL, South Korea, Dec. 2, 2011 — Samsung Electronics Co. Ltd. has begun mass production of the 40-in. Optical Sensor in Pixel interactive liquid crystal display (LCD) panel, which features advanced optical sensors. Because the display panel can perform touch and multitouch sensing and image display simultaneously, it represents a new paradigm for massively interactive communications compared to the one-way communication of today’s kiosk touch panels, the company said. The panel can detect more than 50 touch points...

Terahertz Computed Tomography Helps ID Chemical Substances
Dec 1, 2011 — As radiation sources become more efficient, detectors become more sensitive, and acquisition speeds up, terahertz computed tomography holds promise for nondestructively finding and distinguishing between different materials by visualizing spatial...
Research at the Nanoscale Boosts Green Photonics
Dec 1, 2011 — Improving the efficiency of thin-film solar cells is a key challenge, and some believe that nanophotonics could be the answer. Nanophotonic structures give us better control over light, enabling us to manipulate it in ways never seen before...
Proper Load Distribution Ensures Stable Operation
Dec 1, 2011 — With vibration-isolated platforms, questions of load distribution and static stability of pneumatic support systems are not always properly understood. This can create difficulties when setting up modern optoelectronic systems. Optical tables on...
3-D Optical Microscopy Expands Applications
Dec 1, 2011 — High-speed operation has enabled the 3-D optical microscope to transition successfully from a precision laboratory instrument to a rugged, frontline industrial tool for quality control and process-monitoring applications in diverse industries....
Ending on an Up Note
Dec 1, 2011 — At the close of a year in which the industry weathered global economic storms and tragic natural disasters, we’re happy to report a little good news: After prices for cerium oxide and other rare-earth elements climbed to stratospheric levels...
Smart petri dish analyzes cell growth
PASADENA, Calif. — Built from a smartphone, a commercially available cell phone image sensor and some Lego blocks, ePetri isn’t like other petri dishes. The compact, lens-free microscopy imaging platform can track cell cultures and bacteria as they incubate....
"Mirage effect" from carbon nanotubes hides objects
DALLAS — A cloaking device made from sheets of transparent carbon nanotubes takes advantage of the mirage effect — an optical phenomenon in which light rays are bent to produce a displaced image of distant objects or the sky — to make objects...
Improved photosynthesis increases fuel, food production
SWINDON, UK — Overcoming some fundamental limitations of photosynthesis could lead to major increases in crop yields, bioenergy and the production of renewable chemicals, and five new research projects have taken up the cause. The new research complements...
Compact terahertz device could improve security screening
EVANSTON, Ill. — Using two mid-infrared laser beams, researchers have finally generated single-chip terahertz radiation at room temperature. The technology could speed up and improve a range of processes, including high-sensitivity biological and chemical analysis,...

NOTTINGHAM, UK — A software tool kit encourages students to ask questions and look for deeper reasons behind observations, helping them to think and act like real science investigators. The new approach could spark and sustain interest in science and lead today's...
"Smart" polymer disassembles under low-level NIR irradiation
SAN DIEGO — A unique polymeric material disassembles when exposed to low levels of near-infrared irradiation and is well-tolerated by cells. The new "smart" polymer could be used for noninvasive medical and biological applications. Researchers at the...
Simple nanoantenna separates colors of light
GOTHENBURG, Sweden — A new nanoantenna directs red and blue colors in opposite directions and could lead to optical nanosensors that can detect very low concentrations of gases or biomolecules. Historically, a structure that is smaller than the wavelength of...
Microarray chips enhance clinical diagnostics
AACHEN, Germany — A laser-based benchtop system fabricates protein microarray chips for use in clinical diagnostics, enabling doctors to identify tumor markers in blood samples and to detect pathogens responsible for infectious diseases. Microarray chips for...
IPhone becomes multipurpose imaging tool
DAVIS, Calif. — Using materials that cost about as much as a typical app, scientists have transformed the everyday iPhone into a medical-quality imaging and chemical-detection device that performs detailed microscopy and spectroscopy. The enhanced device...
Laser remelting produces structured surface designs
AACHEN, Germany — Structuring the metallic surfaces of tool inserts by laser remelting allows manufacturers to more quickly and cost-effectively adapt their production processes to incorporate novel structures and design elements. Unlike laser structuring by...
Photonics on ice!
Dec 1, 2011 — Summer comes to the icy vistas of the Antarctic shores. The winds die down a bit, and the temperature climbs (sometimes to above freezing). Most remarkable is the burgeoning population of the unusual bipeds, all puffed up in their striking, yet...
