Technology Research News October 20, 2004	Molecules positioned on silicon Dubbed multi-step feedback control lithography, this new fabrication process could eventually be used to construct prototype molecular electronic devices for future technologies in areas like consumer electronics and biomedical diagnostics.
Technology Research News October 20, 2004	Mechanical valve design goes nano A combination of molecular modeling and classical engineering techniques were used to design a nanomechanical fluid valve that could (in 10 years) be used for drug delivery, biological and chemical testing, and fuel delivery for microscale and nanoscale engines.
Technology Research News October 20, 2004	Angles increase optical storage Ten years from now, one thousand gigabytes of data -- the equivalent of 472 hours of film -- could fit on an optical disk the size of a DVD. That's just over 200 times the storage of today's common 4.7-gigabyte DVDs.
Technology Research News October 20, 2004	Crystal links ultraviolet photons Researchers from Tohoku University in Japan have moved the quest to control entanglement forward with a method that uses the energy from a pair of photons to produce a pair of entangled photons that have the same energy state as the original photons
Military & Aerospace Electronics October 2004 Dave Slack	Active microwave receiver cable can help with antenna location selection Amplifying small signals, those just at the threshold of detectability, before passing them through significant interconnection losses, can cause targets to be detected that may otherwise have been lost.
Military & Aerospace Electronics October 2004	Chip researchers eye moving photons and electrons over the same substrate The new technology should enable systems integrators to move data from a chip directly to optical media. It also may lead the way to revolutionary approaches to all-optical super-high-speed data processing.
Military & Aerospace Electronics October 2004	The move to lead-free solders has its own challenges and hidden problems Peak reflow temperature increases and the imperfectly known characteristics of new materials lie at the core of the problem. Will the new finish layer on the lead frame adhere well to the epoxy? Will the epoxy stick to the die face?
InternetNews October 8, 2004 Susan Kuchinskas	Jeff Hawkins, Innovator Though he may not strive for the robotic capacity of I, Robot, the founder of Palm and Handspring offers a glimpse into the function of intelligence and how he wants to extend that to machines.
Technology Research News October 6, 2004 Eric Smalley	Atomic clock to sync handhelds Its physics package, or atomic works, is about the size of a grain of rice, making it potentially easy to mass produce and integrate with hand-helds and other electronics. It is accurate within 25 microseconds per day, or about a second per 126 years.
Technology Research News October 6, 2004 Eric Smalley	Quantum math models speech Researchers at King's College London and Phonologica Ltd. are using mathematical tools from quantum physics that could lead to improved telecommunications, speech recognition and speech synthesis technologies.
