Image 1 - New Path To Flex And Stretch Electronics
2011-12-14 05:49:35

Berkeley Lab Researchers Develop Solution-based Fabrication Technique Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make “smart devices” nearly ubiquitous. Among the applications that have been envisioned are electronic pads that could be folded away like paper, coatings that could monitor surfaces for cracks and other structural failures, medical bandages that could treat infections and...

Since the invention of liquid crystal displays in the mid-1960s, display electronics have undergone rapid transformation. Recently developed organic light-emitting diodes (OLEDs) have shown several advantages over LCDs, including their light weight, flexibility, wide viewing angles, improved brightness, high power efficiency and quick response. OLED-based displays are now used in cell phones, digital cameras and other portable devices. But developing a lower-cost method for mass-producing...

New nanoscale electronic state discovered on graphene sheets Researchers from the London Centre for Nanotechnology (LCN) have discovered electronic stripes, called 'charge density waves', on the surface of the graphene sheets that make up a graphitic superconductor. This is the first time these stripes have been seen on graphene, and the finding is likely to have profound implications for the exploitation of this recently discovered material, which scientists believe will play a key role...

Although they found that graphene makes very good chemical sensors, researchers at Illinois have discovered an unexpected “twist”–that the sensors are better when the graphene is “worse”–more imperfections improved performance. “This is quite the opposite of what you would want for transistors, for example,” explained Eric Pop, an assistant professor of electrical and computer engineering and a member of the interdisciplinary research team....

Field emission devices, which produce a steady stream of electrons, have a host of consumer, industrial, and research applications. Recent designs based on nanotubes and other nanomaterials embedded in plastics show initial promise, but have a number of drawbacks that hinder their wide-scale application. The embedded nanotubes, which serve as the source for the electrons, also enable the normally inert plastic to conduct electricity. This has the desired effect of producing a versatile and...

Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and other diseases. Standard sensors employ metal electrodes coated with enzymes that react with compounds and produce an electrical signal that can be measured. But the inefficiency of those sensors leads to imperfect measurements. Carbon nanotubes, cylindrically shaped...

Image 1 - NASA Material Absorbs Light Across Multiple Wavelength Bands
2011-11-09 04:23:46

NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it -- a development that promises to open new frontiers in space technology. The team of engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., reported their findings recently at the SPIE Optics and Photonics conference, the largest interdisciplinary technical meeting in this discipline. The team has since reconfirmed the...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
