This special field revolves around processes for modifying material properties (milling, cooling), composition (filtration, distillation) and type (oxidation, hydration).
Valuable information is available on a broad range of technologies including material separation, laser processes, measuring techniques and robot engineering in addition to testing methods and coating and materials analysis processes.
A new type of microfluidic device that can help industry to optimize paints, coatings for microelectronics and specialty polymers has been developed by National Institute of Standards and Technology (NIST) researchers. The device is made of a chemically durable plastic that is resistant to many common organic solvents. It was fabricated with a rapid prototyping method also developed at the agency.
Described in the Aug. 18 issue of the Journal of the American Chemical Society,* such
NASA decides to send astronauts to Mars and farther out, one of the biggest technological hurdles it will face will be making sure they don’t get thirsty.
A $49,000 toilet at Purdue University may provide part of the answer. When NASA engineers first considered manned missions to Mars to follow the moon landings, they imagined that the astronauts would simply pack lots of water and food.
“We could go to Mars with Apollo technologies,” said Dr. Daniel J. Barta, deputy manag
Time is fast running out for the semiconductor industry as transistors become ever smaller and their insulating layers of silicon dioxide, already only atoms in thickness, reach maximum shrinkage. In addition, the thinner the silicon layer becomes, the greater the amount of chemical dopants that must be used to maintain electrical contact. And the limit here also is close to being reached.
But a Cornell University researcher has caused an information industry buzz with the discover
A new generation of high surface-area porous materials for removing atrazine from water supplies has been developed by researchers at the University of Illinois at Urbana-Champaign. The low-cost and wear-resistant fibers also can remove the hazardous contaminants chloroform and trichloroethylene, both byproducts of the commonly used chlorine disinfection process.
“We’ve shown that we can remove all these impurities to well below the maximum contaminant levels established by the Env
With hundreds of thousands of the nation’s bridges nearing the end of their design lives, cash-strapped states are searching for innovative solutions to repair and replace their decaying structures. One answer may lie in the same material that delivered the stealth aircraft, according to two researchers at the University of Missouri-Rolla.
Composite fiber-reinforced polymer (FRP), first developed for use in the aerospace and automotive industries, may be able to help nurse the rapi
University of Michigan researchers have discovered a way to self-assemble nanoparticles into wires, sheets, shells and other unusual structures using sticky patches that make the particles group themselves together in programmed ways. This method could be used to fabricate new materials and devices for nanotechnology.
