Technology Research News October 22, 2003	Process prints nanoparticles Researchers have coaxed tiny particles of gold, silver and carbon to assemble into patterns on silicon wafers over areas as large as a square centimeter by using electrical charge patterns to attract and position the nanoparticles.
Technology Research News October 22, 2003	Single electrons perform logic The ultimate in transistors, which turn on and off in response to a flow of electricity, is a device that can be tripped by a single electron. Researchers from Hokkaido University have put together an AND logic circuit made from four single-electron tunneling transistors.
Technology Research News October 22, 2003	Embedded rotors mix fluids Researchers have found that it is possible to change the way fluid flows through arrays of tiny rotary motors embedded in a membrane. Minuscule motor arrays could eventually be used to sort, mix and transport molecules for medicine, biology and bioengineering applications.
Technology Research News October 22, 2003	Nanowires boost plastic circuits The move is on to develop flexible, cheap, plastic electronics, but so far organic circuits have fallen far short of silicon chip performance. Researchers from the Hahn-Meitner Institute in Germany have moved the field forward with a new way to make flexible transistors.
Technology Research News October 22, 2003	Chip mixes droplets faster A team of researchers from Duke University has improved a method to mix droplets smaller than a nanoliter, or millionth of a liter. The method makes it possible to mix a pair of merged nanoscale-size droplets in less than two seconds rather than the 90 seconds ordinarily needed.
PC Magazine October 21, 2003	More than a Mirage Need to keep your eyes on the road -- or on the runway? A new breed of heads-up display technology lets you see electronic images like maps and instructions -- at the same time.
CIO October 15, 2003 Tom Krazit	Xerox Minds Its MEMS If you think your data center is too crowded, pay attention to researchers at Xerox, who hope to make optical switches much smaller than today's devices. The secret lies in a technology called optical MEMS, or micro-electrical-mechanical systems.
BusinessWeek October 20, 2003 Otis Port	Super-Radar, Done Dirt Cheap A radar system that uses ubiquitous cell-phone signals is on its way. The technology, called Celldar, seems certain to be deployed, given its myriad civilian and military applications.
PC Magazine October 28, 2003	The Lookout: A Fix for RFID Researchers at RSA Security's lab have come up with a technique they say will eliminate many of the privacy concerns surrounding the use of RFID (radio frequency identification) tags.
PC Magazine October 7, 2003	Wi-Fi Here, Wi-Fi There A mini chip could put wireless networking everywhere.
