Researchers have found that the band gap of semiconductor indium nitride is not 2 eV as previously thought, but a much lower 0.7 eV. Scientists from the Lawrence Berkeley National Laboratory, Cornell University, and Japan's Ritsumeikan University have discovered that a single system of alloys incorporating indium, gallium, and nitrogen can convert virtually the full spectrum of sunlight to electrical current. Such a discovery could eventually lead to the delivery of the most efficient and relatively inexpensive solar cells. For more information, go to www.lbl.gov/science-articles/archive.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
