Graphene, which is composed of a one-atom-thick layer of carbon atoms in a honeycomb-like lattice (like atomic-scale chicken wire), is the world's thinnest material — and one of the hardest and strongest. Indeed, the past few years have seen an explosion of research into the properties and potential applications of graphene, which has been touted as a superior alternative to silicon. Because graphene is a two-dimensional material, "all of it is an exposed surface," says physical...

New observations could improve industrial production of high-quality graphene, hastening the era of graphene-based consumer electronics, thanks to University of Illinois engineers. By combining data from several imaging techniques, the team found that the quality of graphene depends on the crystal structure of the copper substrate it grows on. Led by electrical and computer engineering professors Joseph Lyding and Eric Pop, the researchers published their findings in the journal Nano...

Image 1 - Paper-based Wireless Sensor Could Help Detect Explosive Devices
2011-10-27 11:24:10

Researchers at the Georgia Institute of Technology have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives. The device, which employs carbon nanotubes and is printed on paper or paper-like material using standard inkjet technology, could be deployed in large numbers to alert authorities to the presence of explosives, such as improvised explosive devices (IEDs). "This prototype represents a significant step toward...

Pick your poison from this smorgasbord of recent salmonella outbreaks in the United States: ground turkey; fresh papayas; alfalfa sprouts. That's in 2011 alone, and the list goes on, according to the U.S. Centers for Disease Control and Prevention. But perhaps not for long, thanks to a promising new biosensor nanotechnology that could identify the presence of salmonella bacteria before contaminated food or animals reach the marketplace. In the AIP's journal AIP Advances, research...

In the latest issue of Elsevier´s Materials Today, researchers from Spain and Belgium reported on the innovative use of carbon nanotubes to create mechanical components for use in a new generation of micro-machines. While the electronics industry has excelled in miniaturizing components, with individual elements approaching the nanoscale (or a billionth of a meter), reducing the size of mechanical systems has proved much more challenging. One of the difficulties of shrinking...

[ Watch the Video ] Imagine having skin so supple you could stretch it out to more than twice its normal length in any direction - repeatedly - yet it would always snap back completely wrinkle-free when you let go of it. You would certainly never need Botox. That enviable elasticity is one of several new features built into a new transparent skin-like pressure sensor that is the latest sensor developed by Stanford's Zhenan Bao, associate professor of chemical engineering, in her quest...

Method refined by UC Santa Barbara scientists to synthesize sheets of 'wonder material' graphene is promising link to futuristic technology Making waves as the material that will revolutionize electronics, graphene — composed of a single layer of Carbon atoms — has nonetheless been challenging to produce in a way that will be practical for innovative electronics applications. Researchers at UC Santa Barbara have discovered a method to synthesize high quality graphene in a...
