Image 1 - Graphene Grows Better On Certain Copper Crystals
2011-10-28 04:55:42

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...

Image 1 - New Method Of Growing High-quality Graphene Promising For Next-gen Technology
2011-10-17 08:08:55

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...

An international team of researchers has invented new artificial muscles strong enough to rotate objects a thousand times their own weight, but with the same flexibility of an elephant´s trunk or octopus limbs. In a paper published online today on Science Express, the scientists and engineers from the University of British Columbia, the University of Wollongong in Australia, the University of Texas at Dallas and Hanyang University in Korea detail their innovation. The study elaborates...

2011-10-14 07:06:07

Twist per muscle length is over a thousand times higher than for previous artificial muscles and the muscle diameter is ten times smaller than a human hair New artificial muscles that twist like the trunk of an elephant, but provide a thousand times higher rotation per length, were announced on Oct. 13 for a publication in Science magazine by a team of researchers from The University of Texas at Dallas, The University of Wollongong in Australia, The University of British Columbia in...

'Mirage-effect' Helps To Hide Objects
2011-10-04 10:37:03

Scientists have created a working cloaking device that not only takes advantage of one of nature's most bizarre phenomenon, but also boasts unique features; it has an 'on and off' switch and is best used underwater. The researchers, from the University of Dallas, Texas, have demonstrated the device's ability to make objects disappear in a fascinating video shown here. This novel design, presented today, Tuesday 4 September, in IOP Publishing's journal Nanotechnology, makes use of sheets...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
