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.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
