Solving the mystery of superconductivity

Yong Chu: a man looks inside a tube.

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...

Items coated in nanomolecular materials in blue-green, yellow, orange, red, and purple.

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...
