Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
Nanostructure boosts efficiency in energy transport
Overcoming a critical conductivity challenge to clean energy technologies, Boston College researchers have developed a titanium nanostructure that provides an expanded surface area and demonstrates significantly greater efficiency in the transport of electrons. view more (2009-03-03)
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)
Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor
When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. view more (2009-02-26)
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)
Novel gate dielectric materials: perfection is not enough
For the first time theoretical modeling has provided a glimpse into how promising dielectric materials are able to trap charges, something which may affect the performance of advanced electronic devices. view more (2007-10-17)
Cluster helps to protect astronauts and satellites against 'killer electrons'
ESA's Cluster mission has revealed a new creation mechanism of 'killer electrons'-highly energetic electrons that are responsible for damaging satellites and posing a serious hazard to astronauts. view more (2005-12-23)
Electrons travel through proteins like urban commuters
For Duke University theoretical chemist David Beratan, the results of his 15 years of studying how electrons make their way through some important protein molecules can be summed up with an analogy: how do big city dwellers get from here to there? view more (2007-02-02)
New understanding for superconductivity at high temperatures
An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed. view more (2008-01-14)
New quantum state: two electrons trapped in an excited atom
Researchers from Universitat Autònoma de Barcelona and the University of Salamanca have discovered a method to generate a new quantum phenomenon which had never been explored until now: simultaneous trapping of two particules between two excited energy states. The research, reported in Physical Review Letters may have important applications... view more... (2002-01-23)
Porphyrin electron-transfer reactions observed at the molecular level
Researchers at Temple University have observed and documented electron transfer reactions on an electrode surface at the single molecule level for the first time, a discovery which could have future relevance to areas such as molecular electronics, electrochemistry, biology, catalysis, information storage, and solar energy conversion. view more (2007-08-03)
Silicon nanowires upgrade data-storage technology
Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage. view more (2007-06-11)
Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more... view more...

New plasma transistor could create sharper displays
By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. view more (2009-02-05)
New accelerator technique doubles particle energy in just one meter
Imagine a car that accelerates from zero to 60 in 250 feet, and then rockets to 120 miles per hour in just one more inch. view more (2007-02-15)
Study gives clues to increasing X-rays' power
Three-dimensional, real-time X-ray images of patients could be closer to reality because of research recently completed by scientists at the University of Nebraska-Lincoln and a pair of Russian institutes. view more (2009-06-16)
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)
MIT material puts new spin on electronics
Researchers at MIT's Francis Bitter Magnet Lab have developed a novel magnetic semiconductor that may greatly increase the computing power and flexibility of future electronic devices while dramatically reducing their power consumption. view more (2006-05-25)
New insights into how lasers cut flesh
Lasers are at the cutting edge of surgery. From cosmetic to brain surgery, intense beams of coherent light are gradually replacing the steel scalpel for many procedures. view more (2007-10-26)
More evidence for 'stripes' in high-temperature superconductors
An international collaboration including two physicists from the U.S. Department of Energy's Brookhaven National Laboratory has published additional evidence to support the existence of "stripes" in high-temperature (Tc) superconductors. view more (2006-04-27)
