In conventional field effect transistors, the current through the device can be switched on and off by an electric field. A research team in Poland, however, has developed a new way to control electron current in a transistor-like structure by using the electrons’ spin. The new method can not only tune the electrical current in the device but also the spin-polarization of the electron current.
3DIcon Corporation and Dimension Technologies Inc. announced that they have signed a non-binding Letter of Intent outlining the terms and conditions for 3DIcon to acquire Dimension Technologies.
Males of the Japanese tree frog have learned not to use their calls at the same time so that the females can distinguish between them. Scientists at the Polytechnic University of Catalonia have used this form of calling behavior to create an algorithm that assigns colors to network nodes—an operation that can be applied to developing efficient wireless networks.
A NASA-created application that brings some of the agency's robotic spacecraft to life in 3D now is available for free on the iPhone and iPad. Called Spacecraft 3D, the app uses animation to show how spacecraft can maneuver and manipulate their outside components.
Despite impressive recent advances, holographic television, which would present images that vary with varying perspectives, probably remains some distance in the future. But in a new paper, the Massachusetts Institute of Technology Media Lab's Camera Culture group offers a new approach to multiple-perspective, glasses-free 3D that could prove much more practical in the short term.
A vessel hunting system called “Rough Rhino,” sponsored by the Office of Naval Research and deployed aboard U.S. aircraft, ships and partner nation ships operating in waters off the coast of Senegal and Cape Verde, has helped track more than 600 targets since it’s been in operation. The effort has culminated in 24 boardings.
Cornell University researchers have developed a new method of generating terahertz signals on an inexpensive silicon chip, offering possible applications in medical imaging, security scanning, and wireless data transfer.
The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments. A new optical microscope could make the tough task a whole lot easier. It uses photonic time-stretch camera technology and is the world's fastest continuous-running camera.
Humans and animals have evolved to consume energy very efficiently for movement. If robotic actuation can be made to approach the efficiency of human and animal actuation, the range of practical robotic applications will greatly increase. To help this progression, DARPA has created the M3 Actuation program with the goal of achieving a 2,000% increase in the efficiency of power transmission and application.
Long-time Japanese rivals Sony Corp. and Panasonic Corp. are working together to develop next-generation TV panels based on organic light-emitting diode technology. The move is a reversal of decades of rivalry as they try to catch up with South Korea's Samsung Electronics.
University of Utah physicists developed an inexpensive, highly accurate magnetic field sensor for scientific and possibly consumer uses based on a “spintronic” organic thin-film semiconductor that basically is “plastic paint.” Its inventors say the new type of magnetometer also resists heat and degradation, works at room temperature and never needs to be calibrated.
The Flexible Display Center (FDC) at Arizona State University announced that it has successfully manufactured the world's largest flexible color organic light-emitting display prototype using advanced mixed oxide thin-film transistors. Measuring 7.4 diagonal inches, the device was developed at the FDC in conjunction with Army Research Laboratories scientists.
A team of Case Western Reserve University engineers has designed and fabricated integrated amplifier circuits that operate under extreme temperatures—up to 600 C—a feat that was previously impossible. The silicon carbide amplifiers have applications in both aerospace and energy industries.
Agilent Technologies Inc. announced its Bluetooth low-energy (BLE) test solution on the N4010A wireless connectivity test set was verified by Texas Instruments Inc. (TI) for use with TI's integrated circuits in Bluetooth Smart and Smart-Ready devices.
NLT Technologies, together with its sales and marketing channels in the Americas and Europe, Renesas Electronics America Inc. and Renesas Electronics Europe GmbH, announced the successful development of three mid-size color LCD modules based on projected capacitive touch panel technology.
Lawrence Berkeley National Laboratory theorists and experimenters have led in the exploration of the unique properties of topological insulators, where electrons may flow on the surface without resistance and with their spin orientations and directions intimately related. Recent research at beamline 12.0.1 of the Advanced Light Source opens the way to exciting prospects for practical new spintronic devices that exploit control of electron spin as well as charge.
Researchers from Michigan State University, the NIST Center for Neutron Research, and the NIST Center for Nanoscale Science and Technology have discovered the key to controlling and enhancing the lossless flow of a current with a single electron spin state in a standard superconducting device.
A team of Duke University engineers has created a master "ingredient list" describing the properties of more than 2,000 compounds that might be combined to create the next generation of quantum electronics devices.
Peratech is developing an electronic nose using its Quantum Tunnelling Composite (QTC) material. This new sensor technology detects the presence of volatile organic compounds (VOCs) very rapidly and can recover equally quickly, in a matter of seconds.
After spending nearly five months conducting experiments in one spot, the NASA rover moved for the first time this week, rolling off the rock outcrop where it hunkered down for the Martian winter. Engineers will check its power supply before directing it north to study dust and bedrock.
Touché, a new sensing technique developed by a team at Disney Research, Pittsburgh, and Carnegie Mellon University, is a form of capacitive touch sensing, similar to what’s used in smartphone touchscreens. But its ability to monitor capacitive signals across a broad range of frequencies allows it to perform functions based on complex movements: doorknobs that know when to lock based on the type touch, for example.
An interdisciplinary team of engineers at the University of Arkansas has developed a wireless health-monitoring system that gathers critical patient information, regardless of the patient's location, and communicates that information in real time to a physician, hospital, or the patient herself.
Part helicopter, part airplane, the Office of Naval Research-sponsored Flexrotor vertical takeoff and landing unmanned aerial vehicle has an oversized propeller with helicopter-like controls for vertical takeoff and landing and the wings of a conventional aircraft. If successful, the craft will extend UAV surveillance capabilities to smaller platforms like ships.
By employing powerful X-rays that can see down to the molecular level of organic materials used in printable electronics, researchers are now able to determine why some materials perform better than others. Their findings could lead to cheaper, more efficient printable electronic devices.
A team of Rice University students has invented a machine designed to improve the process of correcting bone deformities in children. Typically, bone correction devices are manually operated, which children must remember to use and which introduces the possibility of damaging fragile tissues and nerves. The new automated linear lengthener avoids these risks.
