Building on the work of Japanese researchers, Scott Chambers and other scientists at Pacific Northwest National Lab (PNNL) think they have a better semiconducting material that one day will lead to faster computing speeds and better data storage. Understanding why the material is better requires an understanding of spintronics—the exploitation of an electron's spin for carrying information. Today's computers use an electron's charge for storing and processing information, which is limited by speed and storage density. Conversely, magnetic storage relies on properties created by an electron's spin. Harnessing the spin creates the possibility of creating new signal processing that could increase speed and data storage densities. What makes Chamber's work on semiconducting materials important is the material's magnetic properties. "Our material has superior magnetic strength," says Chambers. "It's an improvement of nearly a factor of five," he adds. One key to the new material, made from titanium, oxygen, and cobalt, is the technique PNNL scientists use for making it. The method uses atomic beams generated in a vacuum and then directed onto a crystalline surface of strontium titanium where the atoms condense and form a thin film. The magnetic properties were tested and validated by IBM's Almaden Research Center in San Jose, CA. PNNL has turned in an invention report and is pursuing a patent application with the United States Patent and Trademark Office.

Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
