Technology Research News October 6, 2004 Kimberly Patch	Fluid chip does binary logic Researchers are working to combine many gates to make a microfluidic computing system. The technology could lead to inexpensive, easily-manufacturerd handheld labs-on-a-chip that do not require control electronics.
Technology Research News October 6, 2004	Crystal structure tunes nanowires A new process that controls the crystal structure of nanowires made from specific semiconductors may enable electronic components, such as light-emitting diodes and laser diodes, with tunable properties.
Technology Research News October 6, 2004	Gas flow makes electricity Gas flows at speeds as low as a few meters per second over semiconductor materials and carbon nanotubes have produced electricity. The phenomenon could lead to small, inexpensive, accurate gas flow sensors in less than two years, according to the researchers.
Technology Research News October 6, 2004	Sound makes electricity for space A compact generator that converts heat to electricity with the relatively high efficiency of 18 percent is especially appropriate for generating electricity aboard spacecraft, according to the researchers.
Technology Research News October 6, 2004	Design rules build on self-assembly Researchers at the University of Michigan have developed computer simulations that promise to speed the process of finding ways to build practical nanostructures, including precisely-structured materials, electronic and optical components, and chemical sensors.
Technology Research News October 6, 2004	Nanotube diode reverses itself A minuscule p-n junction diode that could be used as a field-effect transistor or a light-emitting diode is a step forward in the push to make nanoscale electronic components.
Wired October 2004 Ed Regis	The Incredible Shrinking Man K. Eric Drexler was the godfather of nanotechnology. But the MIT prodigy who dreamed up molecular machines was shoved aside by big science - and now he's an industry outcast.
IndustryWeek October 1, 2004 John Teresko	Plasma Window Reinvents Electron Beam Welding Considering electron beam welding? Get ready to evaluate a process innovation designed to deliver high quality without dependence on a vacuum chamber.
Industrial Physicist Oct/Nov 2004 Jesse H. Ausubel	Big Green Energy Machines Zero-emission power plants and Continental SuperGrids can multiply the power of the energy system 5-10 times while shrinking it in a revolutionary way.
Industrial Physicist Oct/Nov 2004 Eric J. Lerner	Less is More with Aerogels With the lowest density, highest thermal insulation, lowest refractive index, and highest surface area per unit volume of any solid, aerogels exhibit remarkable properties and now this laboratory curiosity is showing some practical uses.
