Scientists demonstrate effect of confining dielectrics on semiconductor nanowire conductivity
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS), in collaboration with researchers from Worcester Polytechnic Institute (WPI), have demonstrated, for the first time, that the activation energy of impurities in semiconductor nanowires is affected by the surrounding dielectric and can be modified by the choice of the... view more...

Power to the people
You`ve just settled in front of the TV to watch your favourite programme when the lights go out and the TV goes blank. Power cuts are annoying for anyone, but can be particularly costly for companies supplying power who suffer financial penalties if they fail to deliver. At the inaugural meeting of the Dielectrics Group of the Institute of Physics... view more... (2001-12-17)
Polymer electric storage, flexible and adaptable
The proliferation of solar, wind and even tidal electric generation and the rapid emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage. Now a team of Penn State materials scientists is developing ferroelectric polymer-based capacitors that can deliver power more rapidly and are much... view more... (2008-08-20)
How can we make nanoscale capacitors even smaller?
Researchers at UC Santa Barbara have discovered what limits our ability to reduce the size of capacitors, often the largest components in integrated circuits, down to the nanoscale. view more (2006-10-13)
ETH Zurich Develops a Single-chip Microsensor System to Analyse Gases
There are many target application areas envisaged for the gas sensor chip. Air quality in closed rooms can be monitored. The presence of dangerous - even poisonous - substances in the air can be detected, such as benzene from petrol pumps or perchloroethylene from dry-cleaning installations, and warnings can then be issued. Low-cost Mass... view more... (2001-11-14)
Testing, radiation testing: Northwestern transistors on space station
Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing. view more (2008-06-11)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Forget the freezer: Research suggests novel way to control water behavior
Researchers may be able to "freeze" water into a solid, not by cooling but by confining it to narrow spaces less than one-millionth of a millimeter wide, according to new results from an interdisciplinary team of scientists and engineers. view more (2009-02-23)
Blurring the Line Between Magic and Science: Berkeley Researchers Create an 'Invisibility Cloak'
The great science fiction writer Arthur C. Clarke famously noted the similarities between advanced technology and magic. This summer on the big screen, the young wizard Harry Potter will once again don his magic invisibility cloak and disappear. view more (2009-05-04)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)

Certain sizes of nanostructures may be more susceptible to failure by fracture than others. view more (2008-08-04)
Flat bacteria in nanoslits
It appears that bacteria can squeeze through practically anything. In extremely small nanoslits they take on a completely new flat shape. Even in this squashed form they continue to grow and divide at normal speeds. view more (2009-08-18)
UC San Diego Physicists Tackle Knotty Puzzle
Electrical cables, garden hoses and strands of holiday lights seem to get themselves hopelessly tangled with no help at all. Now research initiated by an undergraduate student at the University of California, San Diego has resulted in the first model of how knots form. view more (2007-10-04)
