New research paves the way to manufacturing efficient, stable, and low-cost quantum dot-based light-emitting diodes (LEDs), which is important for the widespread commercial use of these LEDs in large-area, full-color flat-panel displays or as solid-state lighting sources to...

Photonic crystals have received an increasing amount of interest for use as light extractors in light-emitting diodes (LEDs), but their implementation on the surface of LEDs has thus far produced little improvement in extraction efficiency.

Relaxed silicon-germanium (SiGe) has become an important material in the fabrication of high-quality films for various applications. Strain-relaxed SiGe buffers have been produced by at least three known methods. However, these techniques present several disadvantages, such as long growth times, thick...

NASA has partnered with Space Adventures to support the YouTube Space Lab competition that invites students to envision and design their own experiment with the ultimate prize -- flying it on the International Space Station.

The contest opened on October 11, and will continue to accept submissions...

Georgia Tech researchers have discovered how to use a mobile phone to track what is being typed on a nearby computer keyboard. They used a smartphone accelerometer — the internal device that detects when and how the phone is tilted — to sense keyboard vibrations and decipher complete sentences with up to 80 percent...

Smartphone and tablet computer owners have become adept at using finger taps and and drags to control their touchscreens. Carnegie Mellon University researchers have found that this interaction can be enhanced by taking greater advantage of the finger's anatomy and dexterity....

Under Jewish law, religious texts cannot simply be thrown away once they're worn out. While many texts were buried, many synagogues also operated genizahs, or storerooms, to store disused holy texts. The Cairo Genizah is one of the most valuable sources of primary documents for medieval...

dSPACE (Wixom, MI) has added the ADASIS v2 Horizon Reconstructor Blockset (ADASIS v2 HR Blockset) to its range of products for developing advanced driver assistance systems. The Simulink blockset provides access to data on the road ahead. Such data, for example, comes from a navigation system or a special ECU,...

Symtavision (Braunschweig, Germany) has launched SymTA/S 3.0 and TraceAnalyzer 3.0, the first fully integrated versions of these system-level tools for model-based design and trace-based verification. Targeted at automotive, aerospace, automation, and other performance- and safety-critical systems, the...

Open-front refrigerated display cases, which make up roughly 60 percent of the refrigerated cases in grocery stores, provide quick access to chilled products – but they’re hardly energy-efficient. Engineers at the University of Washington and Kettering University are working to cut the...

Using carbon nanotubes bent to act like springs, Stanford researchers have developed a stretchable, transparent skin-like sensor that can be stretched to more than twice its original length and bounce back perfectly to its original shape. It can sense pressure from a firm pinch to...

Researchers at Karlsruhe Institute of Technology have developed a new concept for rechargeable batteries, based on a fluoride shuttle – the transfer of fluoride anions between electrodes – which could allow high energy densities up to ten times as high as those of...

A new system, dubbed “Designing With Vision,” incorporates eye-tracking technology that could help release constraints on creativity imposed by computer-aided design (CAD) tools. Developed by researchers at The Open University and the University of Leeds, the system is devised to break down rigid distinctions between...

MathWorks (Natick, MA) introduces AUTOSAR Target Production Package, a flexible support package available to automotive engineers requiring advanced AUTOSAR capabilities with Simulink and Embedded Coder. The AUTOSAR Target Production Package helps engineers use more features of the AUTOSAR standard with simplified...

Synopsys, Inc. (Mountain View, CA) offers enhancements to its CODE V® optical design and analysis software, acquired as part of Synopsys' acquisition of Optical Research Associates. CODE V 10.4 delivers enhancements to its Beam Synthesis Propagation (BSP) tool that enable optical designers to model and...

D2S, Inc. (San Jose, CA) has introduced TrueMaskTM DS, the industry’s first mask‐wafer double simulation accelerated workstation for R&D exploration, bit‐cell design, hot‐spot analysis, and mask‐defect categorization that comprehends overlapping eBeam shots and dose modulation. TrueMask DS is an...
