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.
