"NANO-CROSSBAR: IBM grows nanotube patterns on silicon wafers"
IBM Corp. has grown catalyst-free nanotube networks on silicon carbide substrates, the company said last week. With atomic-force microscopy verifying the results, researchers at the T.J. Watson Research Center set up grids of nanotubes (in rows and columns), bringing the promise of nanotube transistors arrayed across silicon chips one step closer to reality,. IBM also announced a patent for its "cookbook" that shows how to grow the pure, catalyst-free nanotubes needed in electronics manufacturing, as opposed to the bulk nanotubes that other suppliers are offering for sale today.

"NANOTECH: Star Trek technology comes alive at IDF"
Star Trek's William Shatner shared the podium with Intel Corp. CTO Patrick Gelsinger at the Intel Developer Forum (IDF) here Thursday (Sept. 12), where the chief technology officer disclosed Intel's explorations in the areas of software radios, sensors and silicon photonics. "It's refreshing to be at a conference where the technology is not made of papier-m�ch�," said Shatner. Shatner was there to promote his new book, "I'm Working on That: A Trek from Science Fiction to Science Fact," but his quip was a fitting intro to Gelsinger's keynote address, "Expanding Moore's Law with Silicon Nanotechnology."

"NANOTECH: rebuilding electronics one atom at a time"
Molecular nanotechnology � or "nanotech" as it is popularly called � is the technology of manipulating materials at the molecular level or the "nanoscale (a nanometer spans only three or four atoms.)" And while that may appear futuristic, it is not: Design rules of silicon chips have already dropped below 100 nanometers.

"SMART-DUST: Silicon nanoparticles eyed for chemical detection"
Smart dust results from nanostructuring micron-sized porous-silicon particles so that they have a selective response to light when sensing dangerous chemicals or biological agents. Developed here at the University of California, the process creates a special reflective layer � called a rugate filter � on the surface of the particles. The layer only reflects light in a narrow spectral band. The reflection bands vary, creating a medium that has a 20-bit code, enabling millions of tests to be performed simultaneously. Any given chemical will change the reflectivity of some particles in a cloud, creating a unique signature that can be detected from a distance.
