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...]
Carbon Nanotubes as Conductive Material for Through-Silicon Vias
A research team at Chalmers is working with carbon nanotubes as conductive material for through-silicon vias. Carbon nanotubes are going to be the most reliable of all conductive materials if it is possible to use them on a large scale. This is the opinion of Kjell Jeppsson, a member of the research team. The researchers have demonstrated that two chips can be vertically … [Read more...]
