Analog University Online Launched
National Semiconductor Corp., Santa Clara, Calif., recently launched Analog University, the industry's first online educational resources devoted entirely to analog semiconductor technologies. Designed to meet the information needs of novice, mid-career and experienced design engineers, Analog University is a no-cost online tool created to give designers fast access to technical information and training so they can solve real-world semiconductor applications issues in the shortest possible time.
In addition to Analog University, National introduced Knowledge Base, an online tool featuring the semiconductor industry's most powerful natural language search engine. Knowledge Base allows engineers to sift through vast amounts of technical resources on National's Web Site and generates highly targeted results within one to two seconds.

Technique Shatters Accuracy, Speed Barriers
With the release of Coolit v5.0, Daat Research, Hanover, N.H., is the first CFD company to successfully incorporate embedded mesh technology.
This pioneering approach eliminates dependence on approximate model building techniques, such as resistor networks and lumped parameter (compact) models, thereby simplifying model building while increasing model fidelity and accuracy and delivering order of magnitude increases in calculation speed.

New Composite Anode Materials Developed
Researchers at the Department of Energy's Sandia National Laboratories in Livermore, Calif., have developed a new class of composite anode materials composed of silicon and graphite that may double the energy storage capacities currently possessed by graphite anodes. This would lead to rechargeable Li-ion batteries with more power, longer life, and smaller sizes.
Silicon/graphite electrode materials are promising for applications requiring high capacities delivered at low to moderate rates. The marriage of silicon and graphite may improve specific capabilities of commercial graphite anode materials up to 400%, according to the researchers. When small particles of silicon, which offers more than 10 times the lithium capacity potential of graphite, are combined within a graphite matrix, large capacities are retained. The benefits of these materials together include the large capacities and capacity retention during cycling compared to other high-capacity materials. It can also control its performance by changing the composite composition and microstructure.
