New study confirms exotic electric properties of graphene
First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. view more (2009-11-18)
Rice ties in race for atomic-scale breakthrough
Everybody loves a race to the wire, even when the result is a tie. The great irony is the ultraprecise clocks that could result from this competition could probably break any tie. view more (2009-11-18)
Electron self-injection into an evolving plasma bubble
Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. view more (2009-11-03)

NC State Develops Material That Could Boost Data Storage, Save Energy
North Carolina State University engineers have created a new material that would allow a fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text, far exceeding the storage capacities of today's computer memory systems. view more (2009-10-21)
Rutgers physicists discover novel electronic properties in two-dimensional carbon structure
Rutgers researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices. view more (2009-10-15)
Potential leap forward in electron microscopy
MIT electrical engineers have proposed a new scheme that can overcome a critical limitation of high-resolution electron microscopes: they cannot be used to image living cells because the electrons destroy the samples. view more (2009-10-07)
Discovery Brings New Type of Fast Computers Closer to Reality
Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality. view more (2009-09-28)
Optics made to measure
If you are in the business of developing high-speed electronic components, it pays not to lose sight of the electrons. To keep track of them you will need to use dedicated optical elements, such as those now on offer from UltraFast Innovations GmbH. view more (2009-09-17)
Carbon nanotubes could make efficient solar cells
Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. view more (2009-09-11)
High in sodium: Highly charged tungsten ions may diagnose fusion energy reactors
Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own. view more (2009-09-10)
Laser pulses control single electrons in complex molecules
Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. view more (2009-09-02)
Organic electronics a two-way street, thanks to new plastic semiconductor
Plastic that conducts electricity holds promise for cheaper, thinner and more flexible electronics. This technology is already available in some gadgets -- the new Sony walkman that was introduced earlier this summer and the Microsoft Zune HD music player released last week both incorporate organic light-emitting electronic displays. view more (2009-08-18)
Particles as tracers for the most massive explosions in the Milky Way
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". view more (2009-08-11)
From graphene to graphane, now the possibilities are endless
Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon in computer chips. view more (2009-07-31)
NIST scientists study how to stack the deck for organic solar power
A new class of economically viable solar power cells-cheap, flexible and easy to make-has come a step closer to reality as a result of recent work* at the National Institute of Standards and Technology (NIST), where scientists have deepened their understanding of the complex organic films at the heart of the devices. view more (2009-07-30)
