A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not...

A newly discovered magnetic phenomenon could accelerate data storage by several orders of magnitude. With a constantly growing flood of information, we are being inundated with increasing quantities of data, which we in turn want to process faster than ever. Oddly, the physical limit to the recording speed of magnetic storage media has remained largely unresearched. In experiments performed on the particle accelerator BESSY II of Helmholtz-Zentrum Berlin, Dutch researchers have now achieved...

Completing the story they started by creating synthetic magnetic fields,* scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields. Reported in the journal Nature Physics,** these synthetic electric fields make each atom in a gas act, individually, as if it were a charged particle, but collectively they...

WARREN, Mich., March 18, 2011 /PRNewswire/ -- Since he took delivery of his 2011 Chevrolet Volt electric car with extended-range capability in December, Mike DiPisa is averaging 231 miles per gallon of gasoline. It's because his 26-mile daily commute allows him to run almost gas free. "I haven't filled up my Volt since I took delivery," the Lyndhurst, N.J. resident said. Of the 1,485 miles DiPisa put on his Volt, 1,391 have used using grid electricity. DiPisa's fuel economy is on...

Tomorrow's nonvolatile memory devices "“ computer memory that can retain stored information even when not powered "“ will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance. Using a very fast oscilloscope, researchers led by Dan Ralph, the Horace White Professor of Physics, and Robert Buhrman, the J.E. Sweet Professor of Applied and Engineering Physics, have figured out how to quantify the...

In research appearing in today's issue of the journal Nature Nanotechnology, Nongjian "NJ" Tao, a researcher at the Biodesign Institute at Arizona State University, has demonstrated a clever way of controlling electrical conductance of a single molecule, by exploiting the molecule's mechanical properties. Such control may eventually play a role in the design of ultra-tiny electrical gadgets, created to perform myriad useful tasks, from biological and chemical sensing to improving...

CINCINNATI, Jan. 25, 2011 /PRNewswire/ -- Mid month reports from the U.S. Energy Information Association confirm what your wallet already knows... that gas prices are on the rise across the United States. In fact, there is not a region across the country where prices were not up from the same period a year ago. Additionally, this rise put the price per gallon of gasoline above the $3 threshold in every region across the U.S. with the exception of one. In mid January, Ford Motor Company...

Electronics researchers love graphene. A two-dimensional sheet of carbon one atom thick, graphene is like a superhighway for electrons, which rocket through the material with 100 times the mobility they have in silicon. But creating graphene-based devices will be challenging, say researchers at the National Institute of Standards and Technology (NIST), because new measurements show that layering graphene on a substrate transforms its bustling speedway into steep hills and valleys that make it...
