Researchers shed more light on conversion of water to hydrogen gas
Chemists are several steps closer to teasing hydrogen fuel from water using man-made molecular devices that collect electrons and use them to split hydrogen from oxygen. view more (2005-08-29)
Thermometer For Plasma
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics. This device is a further step forward to controlled nuclear fusion. The device... view more... (2003-09-05)
Cluster Quartet Probes the Secrets of the Black Aurora
Swedish and British researchers have used the European Space Agency`s Cluster spacecraft to unveil the mysteries of the "black aurora", a strange electrical phenomenon that generates dark, empty regions adjacent to the visible Northern and Southern Lights. The new results, to be announced today at a meeting of the American Geophysical Union in San... view more... (2001-12-10)
First demonstration of new laser-driven accelerator technology
A team of UK scientists has used, for the first time, an extremely short-pulse laser to accelerate high-energy electrons over an incredibly short distance. Current accelerators can be hundreds of metres long, this is just a millimetre long. view more (2004-09-28)
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)
Measuring electrical arcs at the micrometer scale
Air is a great insulator-except when it becomes a conductor. Under the right conditions, miniature lightning bolts of electricity will "arc" through the air between two electrically conducting points. view more (2006-03-31)
Mars Express observes aurorae on the Red Planet
Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks. view more (2008-11-24)
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)
New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms vibrate in high definition in real time. view more (2007-03-19)
Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers. view more (2007-07-13)
Dartmouth researchers discover chromium's hidden magnetic talents
Two Dartmouth researchers have determined that the element chromium displays electrical properties of magnets in surprising ways. view more (2008-04-17)
UT-ORNL researchers take step toward understanding superconductivity
A research group at the University of Tennessee and Oak Ridge National Laboratory led by physics professor Pengcheng Dai, along with collaborators at Boston College, has taken a step toward understanding a great physical mystery. view more (2007-12-26)
UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the remote operation of micromachines a possibility. view more (2007-06-01)
G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration,... view more... (2006-06-30)
New design for transistors powered by single electrons
Scientists have demonstrated the first reproducible, controllable silicon transistors that are turned on and off by the motion of individual electrons. view more (2006-02-03)
Rice researchers gain new insight into nanoscale optics
New research from Rice University has demonstrated an important analogy between electronics and optics that will enable light waves to be coupled efficiently to nanoscale structures and devices. view more (2005-09-15)
Scientists reveal how a novel ceramic achieves directional conduction
An international team led by UCL (University College London) scientists at the London Centre for Nanotechnology has unravelled the properties of a novel ceramic material that could help pave the way for new designs of electronic devices and applications. view more (2006-04-20)
Chemists forge a new form of iron
An international team of chemists has discovered a new and unexpected form of iron, a finding that adds to the fundamental understanding of an element that is among the most abundant on Earth and that, in nature, is an essential catalyst for life. view more (2006-06-02)
New '1/f noise' discovery promises to improve semiconductor-based sensors
More sensitive sensors and detectors based on semiconductor electronics could result from new findings by researchers from the United States, Norway and Russia. view more (2007-05-10)
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)
