Solving the mystery of superconductivityby Kathy Chambers 17 Oct, 2013 in Products and Content
At the legendary 1987 American Physical Society conference, sometimes called the “Woodstock of physics”, thousands of physicists descended upon a New York Hilton ballroom to hear about the discovery of high-temperature superconductivity (HTS) in ceramic materials. The world was intrigued with possibilities of magnetically levitated trains and bulk power storage. There was excitement and great hope in the world of condensed-matter physics research. After decades of controversy, many competing theories, and several Nobel prizes later, the vision presented in the ballroom that night is beginning to emerge. DOE researchers and their collaborators are utilizing new technologies to make significant progress solving the HTS mystery. Some of the leading HTS theories are being challenged by using cutting-edge x-ray scattering techniques to discover hidden magnetic waves in high-temperature superconductors and additional breakthroughs are anticipated when DOE’s National Synchrotron Light Source II (NSLS-II) begins operation promising unprecedented energy resolution. The string-theory holographic principle is one of the new conceptual tools being used to study HTS electrons. Electron spectroscopy with synchrotron light is being used to understand HTS structures. And, the sample testing process is being greatly accelerated with the atomic layer-by-layer molecular beam epitaxy system.

Travel through DOE databases; find emerging nanotechnology devicesby Kathy Chambers 16 Jul, 2012 in Technology
In the world of nanomanufacturing, new materials, devices, components and products are emerging at a breathtaking rate. Next-generation nanocoatings are being developed to enhance wear resistance of industrial materials. An infrared retina that includes adaptive sensors has been patented. Self-cleaning skin-like prosthetic polymer surfaces have been developed at Oak Ridge National Laboratory (ORNL). ORNL is also well on its way to creating nano catalysts for diesel engine emission remediation. The sonification of x-ray scattering data is explored at Brookhaven National Laboratory. A high frequency nanotube oscillator has been patented by Lawrence Berkeley National Laboratory. And the National Renewable Energy Laboratory is developing tools to measure biomass at the nanometer scale. Take a trip through OSTI’s databases to see the multitude of discoveries happening at the nanoscale. Find the research resultsin the DOE databases and read more at the OSTI Science Showcase.
