Blueprint brews 3D band-gap crystals
News & Analysis  
6/30/2003   Post a comment
A cookbook developed by University of Toronto researchers describes how to fabricate efficient, large-scale, three-dimensional (3D) photonic band-gap (PBG) crystals. PBG materials enable light from micro-lasers to carry information on-chip the way fiber optics uses light for communication between chips.
Oak Ridge claims sensitivity record for Si MEMS sensor
News & Analysis  
6/23/2003   Post a comment
Now that it has proved the concept of a "small, vibrating nose" built as a silicon microelectromechanical system, Oak Ridge National Laboratory in Tennessee has set itself the task of seeing how small an amount of substance the MEMS design can detect.
MEMS used to accelerate volume production
News & Analysis  
6/19/2003   Post a comment
Bringing microelectromechanical systems (MEMS) into mainstream manufacturing has been the goal over the last two years for Surfaced Technology Systems, which created a family of plasma etch and deposition tools to speed the process.

Sibelius Software Ltd. has successfully applied the principles of artificial intelligence to give the performances of its music software a more humanlike sound.
Neural-net scanner promises early detection of SARS
News & Analysis  
6/16/2003   Post a comment
Researcher Harold Szu, working at the Naval Research Laboratory (Arlington, Va.), has turned advanced target recognition technology into what he hopes will be a method for containing the spread of SARS.
Lab claims world's best MEMS sensor
News & Analysis  
6/12/2003   Post a comment
Oak Ridge National Laboratory in Tennessee is claiming a new world's record by detecting just 5.5 femtograms with its silicon micro-electro-mechanical-system (MEMS) sensor.
Tetrapod nanocrystals could improve solar cells
News & Analysis  
6/9/2003   Post a comment
A new shape for semiconductor nanocrystals—tetrapods, rather than simple spheres, rods and disks—could double the efficiency of "plastic" solar cells, according to the inventor of tetrapods.
Hybrid films herald organic sensors, 'smart' materials
News & Analysis  
6/9/2003   Post a comment
Thin, 1-nanometer films of crystalline clay on germanium substrates are being developed at Purdue University (West Lafayette, Ind.) as a scaffolding for "smart" materials.
Single-electron transistors shed heat
News & Analysis  
6/2/2003   Post a comment
Characterizing the electron flow and the resulting causes of heat dissipation in low-dimensional nanoscale electronics could lead to cool-running single-electron "quantum dot" transistors, according to a researcher here at the University of Wisconsin-Madison.
Researchers tap into quantum dots for optical comm
News & Analysis  
6/2/2003   Post a comment
Semiconducting polymers embedded with lead-sulphide nanocrystals could produce a light source for integrated photonic chips, according to recent work at the University of Toronto.
