Material wastes energy, Case Western Reserve University researcher suggests Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that material - platinum - to make it work better, Chemistry Professor Alfred Anderson urges his colleagues to start anew.
An Office of Naval Research (ONR) universal gateway that gives Sailors access to more accurate, secure, real-time information will be delivered to the fleet in just three years from the project’s inception at ONR officials announced July 11. On any Navy destroyer, cruiser or carrier today, there are two networks: one for combat systems (weapons and sensors) and one for command and control, or C2, which also encompasses intelligence, surveillance and reconnaissance.
Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over - a first step in making the technology more practical. In the so-called spin Seebeck effect, the spin of electrons creates a current in magnetic materials, which is detected as a voltage in an adjacent metal.
Modern-day computers are based on logic circuits using semiconductor transistors. To increase computing power, smaller transistors are required. Moore’s Law states that the number of transistors that can fit on an integrated circuit should double every two years due to scaling. But as transistors reach atomic dimensions, achieving this feat is becoming increasingly difficult.
Researchers from North Carolina State University have developed highly conductive and elastic conductors made from silver nanoscale wires (nanowires). These elastic conductors can be used to develop stretchable electronic devices. Stretchable circuitry would be able to do many things that its rigid counterpart cannot.
New technology promises brighter TV and computer displays University of Utah physicists invented a new "spintronic" organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices.
Next-generation "smart" electrical meters for residential and commercial buildings will have computerized operating systems just as laptops or mobile devices do. On July 10, 2012, the National Institute of Standards and Technology (NIST) published its first-ever draft guidelines* to help utility companies test their procedures for upgrading meters securely from a remote location.
Energy harvesters and wireless sensors are not always deployed under "a walk in the park" operating environments. If anything, the most interesting applications for these technologies tend to be in sectors where conditions are harsh or devices are inaccessible once deployed. Requirements in such operating conditions are stringent enough to make it impossible to even consider wired sensors or battery operated devices.
Project to test smartphone ticketing using iPhone, Android and Blackberry handsets on the largest commuter rail network in the US New York’s MTA Metro-North Railroad, working with transit mobile ticketing specialists Masabi US Ltd., will begin testing a smartphone app that will let people buy their train tickets anywhere, anytime and never have to hold a piece of paper.
Nearly 3,000 solar panels will power a 17-mile stretch of E-470 in Colorado, officials say, lowering costs for drivers. E-470 wraps around the suburbs east of Denver. Solar-generated electricity will power streetlights, toll collection equipment, plaza and maintenance facilities, variable message signs and the E-470 administrative headquarters.
TE Connectivity today announced that its distributed antenna systems (DAS) have been deployed for capacity crowds in key venues at both the Democratic and Republican national conventions. TE’s DAS products, including FlexWave Prism, InterReach Spectrum, and InterReach Fusion will provide “gavel to gavel” 3G and 4G mobile coverage and capacity at these major events, which host thousands of delegates, reporters and support staff who will want to send and receive texts, e-mails, videos, and other bandwidth-intensive data.
The new Galaxy S series, the strongest rival for Apple's iPhone, was launched in Europe in late May and in the United States last month. A Dublin-based consumer posted comments and photos on a web site in June, saying his Galaxy phone had "exploded" while mounted on his car dashboard. He wrote that while he was driving, "suddenly a white flame, sparks and a bang came out of the phone.
The writedown of almost all of that deal's value, announced this week, shows how misguided those expectations were, and how brutal the once-thriving business of selling banner ads on websites has become. The main culprit is an explosion of advertising space offered by Facebook Inc and other websites that is outpacing steady demand.
"We're trying to set up a situation where people share the burden of transportation with each other," said Blake Wirht, director of marketing for San Francisco-based SideCar. When someone requests a ride, nearby drivers can decide if they want to respond. The passenger can compensate the driver via the app at a suggested fare that often undercuts the cost of a taxi.
Japan's Sharp Corp (6753.T) said on Monday it has reached an out of court settlement with Dell Inc (DELL.O) and two other companies that filed a lawsuit over its TFT digital business in North America and Europe. Sharp said it will pay $198.5 million in settlement to the three companies. www.
