Tennessee could become a model for the nation when it comes to protecting the public from chemical, biological or radiological releases.
Already, sensors that are part of Oak Ridge National Laboratorys SensorNet are deployed in Nashville, Knoxville and Oak Ridge, and in other parts of the nation. Additional sensors are planned for Memphis, Chattanooga and Sullivan County in Upper East Tennessee. ORNL project managers envision more being added in the next few years, eventually spanning the state with sensors that would alert emergency responders and the public if they were in danger of being exposed to water or airborne hazards.
Frank Libutti, the Department of Homeland Securitys under secretary for Information Analysis and Infrastructure Protection, was in Nashville today to see first hand how the system works. Also attending the demonstration were several homeland security advisers from neighboring states.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
