General Motors is going to modify its Chevrolet Volt plug-in car to eliminate the possibility that its batteries can catch on fire hours or days after a serious side-impact crash. It turns out that battery coolant could leak on an electronic board, causing the fire. The leaks were discovered in tests in which a Volt was rotated until it was inverted. Only a small amount of … [Read more...]
Nanomaterials Doped Polymer Nanowires Synthesized by Pulsed Laser Irradiation
International Center for Materials Nanoarchitectonics (MANA) has succeeded in synthesizing nanomaterials doped polymer nanowires by a pulsed laser irradiation. The polymer nanowires grew perpendicular to the surface of a source film that included the nanomaterials and dye molecules as a photoabsorber. The technique is one of the solutions for fabricating of molecular devices … [Read more...]
Self-Healing Electronics Could Work Longer, Reduce Waste
A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Led by aerospace engineering professor Scott White and materials science and engineering professor Nancy Sottos, the researchers published their results in the journal Advanced Materials. As electronic … [Read more...]
IBM Retiree Wins Award from Engineers Society
Robert E. Simons was named the 2011 winner of the Allan D. Kraus Thermal Management Medal given recently by the committee that manages the annual award for the American Society of Mechanical Engineers. Simons is a retired IBM senior technical staff member who has had a 45-year career in the management of heat in electronics and holds more than 130 patents. He joined IBM in 1966 … [Read more...]
Tiny Solar Cell Saves Money and Energy
The U.S. Department of Energy's National Renewable Energy Laboratory recently validated greater than 41 percent efficiency at a concentration of 1,000 suns for tiny cells made by Semprius. The energy conversion efficiency of a solar cell is the percentage of sunlight converted by the cell into electricity. Seed money from DOE, together with the experts at the NREL-based … [Read more...]
