EUV: tabletop system generates extreme-UV laser light
Margaret Murnane describes a small, inexpensive tabletop laser system that can produce coherent extreme-ultraviolet laser light has been built by a research team at the University of Colorado. The system uses a hollow optical fiber filled with argon gas as a nonlinear optical waveguide that upconverts visible laser light into the extreme-ultraviolet range � a critical part of the spectrum for advanced lithography systems.

"NANOPARTICLES: synthesis of nanoparticles coming into focus"
Scientists are fast gaining control over the building of tiny particles, accomplishing nanoparticle synthesis in both inorganic and organic chemistries. University of Arkansas researchers here have devised a "green" chemical process that offers tight control over the size of nanoparticles and eliminates toxic by-products. And a team at the University of Michigan (Ann Arbor) is developing dendrimer-based fluorescent particles to monitor human cell damage from radiation.

NANOTRANSISTOR: Cornell demos single-atom transistor
Using a single cobalt atom as a switch, a research team at Cornell University has demonstrated a working transistor only 1.3 nanometers in length. Silicon transistors today are generally more than 100 nm long.

NANOMEM: IBM nanotechnology creates 1-terabit memory chip
ZURICH, Switzerland � IBM Corp. has developed a prototype terabit memory that stores a trillion bits of data, or twenty times more than a current disk drive, in a square inch. Created with micromachining techniques, IBM said the Millipede non-volatile memory is only the beginning of even denser memories. The Millipede chip uses silicon micromachining techniques to precisely move a silicon substrate coated with a thin-film polymer beneath an array of 1,024 parallel activated 20-nanometer read/write heads, which were also etched from silicon.

NANOTUBES: IBM says experimental carbon-based transistor beats silicon
The next generation of semiconductors will be carbon-based if researchers at IBM's T.J. Watson Research Center here have their way. IBM revealed details Monday (May 20) about what it is calling "the world's best transistor," based on a single carbon nanotube measuring 1.4-nanometers in diameter. Fabricated with conventional MOSFET processing technology, IBM characterized both n-type and p-type FETs using carbon nanotubes as the channel.

"ANTI-TERROR: Sandia enlists MEMS sensors to fight terrorism"
On Sept. 11, 2001, a think tank at Sandia National Laboratories started assessing its advanced technologies against the threat of terrorism. In response to that study, Sandia recently funded a program to counter terrorist threats with microelectromechanical systems (MEMS) � not only to sense dangerous chemical, biological and nuclear agents, but also to identify and track the danger itself � the terrorists.
