Scientists have recently carried out the first investigation of 2D fermion liquids using neutron scattering, and discovered a new type of very short wavelength density wave. The team believes their discovery will interest researchers looking at electronic systems, since high temperature superconductivity could result from this type of density fluctuations.
Common material such as polyethylene used in plastic bags could be turned into something far more valuable through a process being developed at Oak Ridge National Laboratory. In a recently published paper, a team led by Amit Naskar of the Materials Science and Technology Division outlined a method that allows not only for production of carbon fiber but also the ability to tailor the final product to specific applications.
While several recent studies suggest that much of the world is likely to experience freshwater shortages as the population increases and temperatures rise, determining the relative impact of each has been difficult. A recent Oak Ridge National Laboratory paper outlines a process that might help.
Identifying chemicals from a distance could take a step forward with the introduction of a two-laser system being developed at Oak Ridge National Laboratory. The technique uses a quantum cascade laser to "pump," or strike, a target, and another laser to monitor the material's response as a result of temperature-induced changes. That information allows for the rapid identification of chemicals and biological agents.
