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.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
