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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
