Atom Trap Is a Step towards a Quantum Computer

Wednesday, June 27th, 2007

by M. Inman News Service, 17 Jun 2007 A device that can hold hundreds of atoms in a 3D array, and image each one individually, has been developed by scientists in the U.S.  The machine is an important stepping stone towards the development of a quantum computer, they say.  Many teams are looking for [...]

Power-Generating Buoys Shelter in the Deep

Wednesday, June 27th, 2007

by C. Brahic News Service, 14 Jun 2007 They look a bit like underwater mines, but they have a far less sinister purpose — the first of these submarine wave-energy devices should sprout up off the U.K. coast in 2008.  AWS Ocean Energy has developed an underwater buoy that harnesses wave energy from 50 [...]

IEL Unavailable

Wednesday, June 27th, 2007

The IEEE/IET Electronic Library will be unavailable from 2:00 p.m.-3:00 p.m. today (June 27) due to scheduled maintenance.  We apologize for any inconvenience this may cause.

Tuning the Quantum Stability and Superconductivity of Ultrathin Metal Alloys

Tuesday, June 19th, 2007

by M.M. Özer et al. Science, 15 Jun 2007 Quantum confinement of itinerant electrons in atomically smooth ultrathin lead films produces strong oscillations in the thickness-dependent film energy.  By adding extra electrons via bismuth alloying, we showed that both the structural stability and the superconducting properties of such films can be tuned. The phase boundary [...]

Call for Papers – International Solid-State Circuits Conference

The 2008 IEEE International Solid-State Circuits Conference is being held in San Francisco, California, USA, on 3-7 February 2008.  A call for papers has been announced for the conference, with the theme being “System Integration for Life and Style.”  Contributions are sought from authors who demonstrate ways in which the integration of novel circuit and [...]

Nanoparticles Unlock the Future of Superalloy Metals

Tuesday, June 19th, 2007

Sandia National Laboratories Press Release, 13 Jun 2007 Sandia National Laboratories is pioneering the future of superalloy materials by advancing the science behind how those superalloys are made.  As part of Sandia’s nanoscale research, a group of experts specializing in inorganic synthesis and characterization, modeling, and radiation science have designed a radical system of experiments [...]

Bones Could Allow Data Swaps via Handshake

Tuesday, June 19th, 2007

by P. Marks News Service, 13 Jun 2007 Your backbone’s connected to your shoulder bone, your shoulder bone’s connected to your neck bone — and your neck bone’s connected to your cellphone.  Something along these lines is what Lin Zhong and Michael Liebschner at Rice University envisage.  They want to use the human skeleton [...]

Optical Remote Inspection of Live Contact-Wire Cross-Sections

Tuesday, June 19th, 2007

by Y. Chugui et al. SPIE Newsroom, accessed 19 Jun 2007 One of many important railroad maintenance tasks is the inspection of the condition of the contact wire that supplies electricity to a train.  Over long periods of operation the wire deteriorates, and these changes in its shape must be monitored.  But measurement is tricky [...]

Analytical Model of Planar Grids and High-Impedance Surfaces Comprising Metal Strips or Patches

Thursday, June 14th, 2007

by O. Luukkonen et al. E-print Archive, 24 May 2007 This paper introduces simple analytical formulas for the grid impedance of electrically dense arrays of metal strips or square patches and for the surface impedance of high-impedance surfaces based on such grids over ground planes.  The emphasis is on the oblique-incidence excitation, for which case [...]
