Nano antenna amplifies light by a factor of 1,000

By - September 24, 2010 2 Pictures
Scientists at Houston’s Rice University have successfully increased the intensity of laser light a thousand-fold by shining it into a “nanoantenna.” At the heart of the device are two gold tips, separated by a gap measuring about a hundred-thousandth the width of a human hair. At the point where it passed through that gap, the light was “grabbed” and concentrated. Condensed matter physicist Doug Natelson believes that the technology could be useful in the development of tools for optics and chemical/biological sensing, with applications in industrial safety, defense and homeland security.

Latest spintronics breakthrough detects flow of spinning electrons in real time

By - August 24, 2010
Spin electronics, or “spintronics” promises to revolutionize computing. We’ve covered numerous breakthroughs in the field including controlling the spin of electrons, manipulating single electrons independently, and the first plastic spintronic computer memory device. However, one major hurdle for spintronics researchers has been the difficulty in detecting the flow of spinning electrons in real time. The discovery of a new way to recognize currents of spinning electrons within a semiconductor changes that and could lead the way to the development of superior computers and electronics. Read More

Researchers demonstrate first plastic spintronic computer memory device

By - August 10, 2010
Spintronics – or spin electronics – is an emerging technology that exploits the intrinsic spin of the electron rather than its charge, as is the case with current electronic devices. The technology promises microelectronic devices that can store more data in less space, process data faster, and consume less power. Researchers at Ohio State University (OSU) have now demonstrated the first plastic memory device that utilizes the spin of electrons to read and write data. Read More

Color matters: GreenSun Energy colored solar technology

By - September 24, 2009 4 Pictures
One of the most common ways to turn the sun's energy into electricity is by persuading silicon to give up some of its electrons. But it's also quite expensive, so any innovation that helps reduce the cost of solar cell production is welcome. Researchers in Israel have come up with a cell that uses only 20% of the silicon in a standard cell yet yields similar amounts of electricity. It does this by diffusing any light that falls on its surface and sends it off to photovoltaic collector strips on each of its sides. And it doesn't even need bright sunlight to operate. Read More

Large Hadron Collider readies for half-power restart

By - August 11, 2009
The date 10 September 2008 was forseen by some as the end of the world, at least if you believed scientists who were trying to pull the plug on an experiment that some dubbed the ‘Doomsday Test’. As it turned out a faulty electrical connection brought proceedings to a halt. Now the $9 billion ‘atom-smasher’, aka the Large Hadron Collider, which was developed by CERN to recreate the chemical reactions that took place when the universe came into existence around 14 billion years ago, is gearing up for a restart.
