Deborah Chung, Ph.D., professor of mechanical and aerospace engineering at the University at Buffalo (Buffalo, NY), discovered semiconducting behavior from an unusual source: a carbon composite. Her work endows structural materials with electronic capabilities without computer chips or electrical leads. Chung says, "We can use the structural material itself as the electronics." Made from carbon fibers embedded in a polymer matrix, the material would be easier and less expensive to fabricate than traditional silicon-based electronics, says Chung. According to the researcher, the process spreads electronic capabilities over a large surface area, therefore heat dissipation--now one of the biggest technological challenges facing electronic packaging--would no longer be a problem. Chung's work was presented at the International Symposium on Smart Structures and Materials in San Diego on March 4. Call (716) 645-3811.
Fifty-six-year-old Pasquale Russo has been doing metalwork for more than 30 years in a tiny southern Italy village. Many craftsmen like him brought with them fabrication skills when they came from the Old World to America.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
