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.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
