Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand. The breakthrough is a method for creating and attaching the tiny wires that will connect molecular components, reports a new study in the Journal of the American Chemical Society. Yuji Okawa and colleagues write that the "key to single-molecule electronics is...

By swapping one superconducting material for another, researchers at the National Institute of Standards and Technology (NIST) have found a practical way to boost the efficiency of the world's fastest single-photon detector, while also extending light sensitivity to longer wavelengths. The new tungsten-silicon alloy could make the ultrafast detectors more practical for use in quantum communications and computing systems, experiments testing the nature of reality, and emerging applications...

COLLEGE PARK, Md., June 9, 2011 /PRNewswire-USNewswire/ -- No one is happy about rising gas prices, and to make matters worse, up to 60 percent of each $4 gallon is wasted, lost as heat that pours out of the exhaust pipe. But what if some of that heat could be collected and converted back into electricity that can recharge the battery that powers the lights, wipers, power steering, or even the electric motor in a hybrid vehicle? The technology to do just that exists, but it's still a work...

'Quantum coaxial cable' nanostructure efficiently harvests visible wavelength light using stable, high bandgap semiconductors A report, published in the March 14 edition of the Journal of Materials Chemistry, announced the successful fabrication and testing of a new type solar cell using an inorganic core/shell nanowire structure. Arrays of core/shell nanowires (described has "quantum coaxial cables") had previously been theorized as a potential structure that, while composed of chemically...

Anne M Stark, LLNL Unlike many conventional chemical detectors that require an external power source, Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires, rather than traditional batteries. The device overcomes the power requirement of traditional sensors and is simple, highly sensitive and can detect various molecules quickly. Its development could be the first step in making an easily deployable chemical sensor for the battlefield. The Lab's...

Surprising phenomenon may lead to greater sensitivity in image sensor devices Engineers may soon be singing, "I'm going to wash that gray right out of my nanowires," thanks to a colorful discovery by a team of researchers from Harvard University and Zena Technologies. In contrast to the somber gray hue of silicon wafers, Kenneth B. Crozier and colleagues demonstrated that individual, vertical silicon nanowires can shine in all colors of the spectrum. The vibrant display, dependent on the...

Focusing on interdisciplinary research is now leading to breakthroughs in bio nanotechnology research. A new method for drug development has become a reality. Four years ago, the biologist Karen Martinez almost didn't believe in the research project herself when she started with her team working on it, but now it has been proven. Together with colleagues at the Nano-Science Center, her team has been able to combine nanoscale materials and technologies that are traditionally used for...

After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements "” a finger pinch now en route to a pulse beat in the future "” to generate electricity. Speaking here today at the 241st National Meeting & Exposition of the American Chemical Society, they described boosting the device's power output by thousands times and its voltage by 150 times to finally move it out of the...

New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at the University of Copenhagen is behind the sensational new theoretical model, which is developed in collaboration with researchers from CINAM-CNRS in Marseille. One of the most important components in future electronic devices will likely be based on nanocrystals, which are smaller than...
