What do you get when you subject Nitrogen to pressures 2.4 million times the atmospheric pressure at sea level? The answer is a new form of Nitrogen that is a semiconducting solid. For the first time, scientists at Carnegie Institute at Washington made electric measurements on the condensed gas. This new dense form of Nitrogen stores energy, which they say makes it viable for semiconducting material. The material remains stable after the pressure is removed. The institute's work is partially funded by the National Science Foundation's Division of Materials Research. The findings also confirm theories about superconductivity properties in other elements, such as Hydrogen. For more information, contact the institute's team leader Russell Hemley at (202) 478-8951.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
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.
