Simulations help North and South Dakota researchers decide which technology would make a better solar collector, quantum dot or nanowire A trio of researchers at North Dakota State University, Fargo, and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires. Andrei Kryjevski and his colleagues, Dimitri...

New OLEDs For Fully Stretchable Electronics
2013-09-24 04:14:47

[ Watch the Video: Flexible and Stretchable LEDs ] April Flowers for redOrbit.com - Your Universe Online Can you imagine a curtain that illuminates a room, or an electronic display almost as clear as a window? How about a smartphone screen that doubles in size and stretches like rubber? Researchers from the UCLA's Henry Samueli School of Engineering and Applied Science recently developed a transparent, elastic, light-emitting device (OLED) that might just make these devices possible one...

Electronic devices with touchscreens are ubiquitous, and one key piece of technology makes them possible: transparent conductors. However, the cost and the physical limitations of the material these conductors are usually made of are hampering progress toward flexible touchscreen devices. Fortunately, a research collaboration between the University of Pennsylvania and Duke University has shown a new a way to design transparent conductors using metal nanowires that could enable less...

Your Signature In Lights
2013-08-12 06:20:58

Georgia Institute of Technology Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a fingerprint – directly into light signals that can be captured and processed optically. The sensor device could provide an artificial sense of touch, offering sensitivity comparable to that...

For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions of transistors on a single silicon chip. But transistors based on semiconductors can only get so small. “At the rate the current technology is progressing, in 10 or 20 years, they won’t be able to get any smaller,” said physicist Yoke Khin Yap of Michigan Technological University. “Also, semiconductors have another disadvantage: they waste a...

Nanowires Precisely Positioned Using Sound Waves
2013-06-19 10:28:48

Penn State The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits. "There are ways to create these devices with lithography, but it is very hard to create patterns below 50 nanometers using lithography," said Tony Jun...

Ulsan National Institute of Science and Technology(UNIST) Eye contact lenses, picture-taking and scanning, possibly, a wearable black box A hybrid transparent and stretchable electrode could open the new way for flexible displays, solar cells, and even electronic devices fitted on a curvature substrate such as soft eye contact lenses, by the UNIST(Ulsan National Institute of Science and Technology) research team. Transparent electrodes are in and of themselves nothing all that...

Solar Power Through Painted On Organic Photovoltaics
2013-05-14 05:58:22

Lee Rannals for redOrbit.com - Your Universe Online Researchers at the University at Buffalo are developing a technique that could allow for solar panels to be painted on some day. The team wrote in the journal Advanced Materials they are helping to develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than today's solar panels. These devices are processed in liquid form and can be applied to a variety of surfaces. “Compared with...

Motion Converted To Electronic Signals For Tactile Imaging By Piezoelectric 'Taxel' Arrays
2013-04-25 21:27:07

Georgia Institute of Technology Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices. The arrays include more than 8,000 functioning piezotronic transistors, each of...

Nanowires Grown On Graphene Have Surprising Structure
2013-04-24 12:04:44

University of Illinois When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications. Led by professor Xiuling Li, in collaboration with professors Eric Pop and Joseph Lyding, all professors of electrical and...

Word of the Day
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
'Cacodemon' comes from a Greek term meaning 'evil genius.'
