Researchers at the University of Copenhagen have developed a new nanotechnology platform for the development of molecule-based electronic components using graphene. At the same time, they have solved a problem that has challenged researchers from around the world for ten years.
New and better ways of measuring high-tech energy consumption could lead to significant environmental and economic gains, a study from The Australian National University (ANU) has found. Researchers from ANU, the University of Texas at Austin, and the University of Washington have completed the first systematic profile of microprocessors, which could help lower the energy costs of electronic devices.
Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing. This improvement can be seen by measuring amplitude instead of frequency.
Most RFID tags that are to be used on metal objects are made by placing an antenna on a spacer. Such tags can be easily damaged because they stick out. New tags, developed by North Dakota State University researchers and being presented at an upcoming IEEE workshop, use the metal objects themselves as the antenna.
A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring blood oxygen in stroke patients in the hospital. Unlike a pulse oximeter, which also performs this task, the head patch uses near-infrared spectroscopy to quickly the presence of another stroke.
One day in 2010, Rutgers University physicist Vitaly Podzorov watched a store employee showcase a kitchen gadget that vacuum-seals food in plastic. The demo stuck with him. The simple concept—an airtight seal around pieces of food—just might apply to his research: Developing flexible electronics using lightweight organic semiconductors for products such as video displays or solar cells.
Kodak is at a crossroads: It could go the way of Circuit City, or it could prosper after bankruptcy like General Motors. Even in bankruptcy, the company boasts some enviable strengths, including a rich collection of photo patents, and more than $4 billion in annual sales. But it may be too late for a transition.
Although still two years away for consumers, the next generation of mobile technology will be up to 500 times faster than 3G smartphones. Approved this week at a United Nations radio communications meeting, the technology standard is called IMT-Advanced and will use the radio-frequency spectrum much more efficiently.
After a long decade of deliberation, United Nations member countries will cast their vote this week on an issue that lasts literally just a second. Leap seconds are necessary to prevent atomic clocks from speeding ahead of solar time, but the United States and other countries want to abolish it for all time.
In recent years nanoscale thermal analysis has been employed to reveal the temperature-dependent properties of soft polymers at the nanoscale. Researchers at the University of Illinois at Urbana-Champaign and Anasys Instruments, Inc. have now shown that they can perform this nanoscale thermal analysis on stiff materials like epoxies and filled composites.
A team in Germany has built a transmitter less than a millimeter square that has generated the highest frequency ever attained by a microelectronic device: 1.111 THz. Compared to previous transmitters that have been bulky and expensive, the new device could soon find use in engineering applications.
A University of California, Riverside team has made a breakthrough discovery with graphene, a material that could play a major role in keeping laptops and other electronic devices from overheating. The team has shown that the thermal properties of isotopically engineered graphene are far superior to those of graphene in its natural state.
Manufacturing inspectors usually time procedures manually in order to organize manual assembly operations efficiently. This method is prone to error. A new system invented in Germany records times automatically, helping to costs for companies.
Researchers have created a new type of optical device, the passive optical diode, small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
An innovative design for a small-volume molecular imaging instrument by University of Pittsburgh physicists has been hampered by a major question: How does one measure a magnetic field accurately using the resonance of single electrons within a diamond crystal? It’s too difficult with normal computers, but the scientists think they may now have an answer.
Atomic force microscope cantilever tips with integrated heaters are widely used to characterize polymer films, and to study fundamentals of nanometer-scale heat flow. Until University of Illinois engineers adapted such a tip to read electrothermal voltage, however, no one had used a heated nano-tip for electronic measurements.
BriskHeat Corporation has recently released the Centipede 2, a temperature control system that economically controls multiple heaters in a system. Each heater in a system has its own PID temperature controller and RTD sensor, and individual PID control improves temperature uniformity across a system.
Aerotech’s new A3200 MotionPAC is a software-based programmable logic controller that is completely integrated with the company’s A3200 motion controller to increase programming efficiency, increase quality, and decrease development time by 30 to 50%.
Cities are wasting the potential of smart technologies by failing to realize the value of their hidden infrastructure and digital assets. A report published by The Climate Group, Accenture, Arup, and Horizon Digital Economy Research at The University of Nottingham says opening up data and digital assets is critical to accelerating low carbon cities.
Individual molecules have been used to create electrical components like resistors, transistors, and diodes, that mimic the properties of familiar semiconductors. But according to Nongjian Tao, a researcher at the Biodesign Institute at Arizona State University, unique properties inherent in single molecules may also allow designers to produce novel devices whose behavior falls outside the performance observed in conventional electronics.
Molybdenite, a mineral of molybdenum disulfide, was shown earlier this year to be an effective band gap semiconductor and a possible competitor to graphene. EPFL scientists have now made the first molybdenite microchip, boasting smaller and more energy-efficient transistors than traditional silicon.
Exotic materials called topological insulators, discovered just a few years ago, have yielded some of their secrets to a team of Massachusetts Institute of Technology researchers. For the first time, the team showed that light can be used to obtain information about the spin of electrons flowing over the material's surface, and has even found a way to control these electron movements by varying the polarization of a light source.
Researchers at the University of Pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule. The incorporation of such single-molecule elements could enable smaller, faster, and more energy-efficient electronics.
There has been enormous progress in recent years toward the development of photonic chips—devices that use light beams instead of electrons to carry out their computational tasks. Now, researchers at the Massachusetts Institute of Technology have filled in a crucial piece of the puzzle that could enable the creation of photonic chips on the standard silicon material that forms the basis for most of today's electronics.
Instead of sending grandma a holiday photo of the family for her fridge, imagine calling up the image on your computer monitor, clicking “print,” and producing a 3D plastic model ready for hanging on the holiday tree. According to a American Chemical Society editor, scenes like that are fast approaching reality.
