Teleportation exits realm of sci-fi
News & Analysis  
8/30/2004   Post a comment
The problem with teleportation — the real beam-me-up-Scotty kind — is not its principles, which appear to be sound, but in the devil's details.
Tangled states

In Einstein's prophetic world, fact is stranger than fiction. In the TV show Star Trek, beam-me-up-Scotty teleportation was only possible within the range of the "transporter," but in Einstein's world, teleportation is not limited by range.
Toyota reports silicon carbide wafer advance
News & Analysis  
8/30/2004   Post a comment
Toyota Central Research and Development Laboratories Inc. (Aichi, Japan) will announce the development of ultrahigh-quality single-crystal silicon carbide 3-inch wafers at the Fifth European Conference on Silicon Carbide and Related Materials, which begins Tuesday in Bologna, Italy.
Nanoscale parts get binding aid
News & Analysis  
8/23/2004   Post a comment
Nanoscale particles that are easy to manufacture piecemeal — but hard to assemble — may benefit from a new "sticky patch" technology that researchers at the University of Michigan say enables nanoscale self-assembly.
Bonding breakthrough may ease MRAM design
News & Analysis  
8/16/2004   Post a comment
For all their promise, magnetic random-access memories have barely made it out of the lab due to problems plaguing their scaling to smaller sizes — namely, the need for lower drive current and thinner metallization.
Researchers simplify quantum-dot manufacture
News & Analysis  
8/16/2004   Post a comment
A research team from the State University of New York at Buffalo claims to have discovered a simple way to mass-produce semiconductor nanocrystals precisely, in nearly any desirable size, using a technique based on self-assembly and room-temperature chemistry.
Quantum dots poised for production line
News & Analysis  
8/10/2004   Post a comment
University researchers are using self-assembly techniques and chip-related chemistry to develop a process for mass producing tiny crystals called quantum dots.
Wireless transceiver-on-chip now possible, team says
News & Analysis  
8/9/2004   Post a comment
A research team from Michigan-based universities says it has succeeded in integrating the last two components needed to create a one-chip wireless transceiver.

Ever since Texas Instruments Inc. and Fairchild Semiconductor Corp. cross-licensed their technologies to offer the first commercially available microchips in 1961, two components had continued to resist shrinkage-the antenna and the time base.
Futuristic factories make mesh
