Scientific ProgramsThe UNICAT mission to provide advanced x-ray techniques to a diverse scientific community is achieved through the development of two sectors at the Advanced Photon Source. At these facilities, UNICAT members pursue scientific endeavors which are consistent with the research mission of their institutions. The primary research areas of UNICAT members encompass Materials Sciences and Condensed Matter Physics. The breadth of this collaborative effort is reflected by the wide selection of x-ray techniques that are used to study an extensive list of materials problems.UNICAT Member InstitutionsOAK RIDGE NATIONAL LABORATORYSeveral Divisions at ORNL are actively involved in synchrotron radiation research, lead by the Solid State Division and the Metals and Ceramics Division. Their missions are to characterize and understand the properties and interactions of a wide range of materials used in advanced energy technologies, to develop new materials and materials processing techniques that extend the capabilities of existing technologies, to develop and maintain materials characterization and processing facilities needed in the DOE programs, and to develop and maintain productive research and technology transfer relationships with universities and industries in related areas of materials science.NATIONAL INSTITUTE OF SCIENCE AND TECHNOLOGYTo promote the U.S. economy and public welfare, the Laboratories of the National Institute of Standards and Technology provide technical leadership for the measurement and standards infrastructure, and assure the availability of measurement capabilities. Materials science and engineering programs at NIST cover the full range of materials issues from design to processing to performance. A unifying aim is to acquire the knowledge and tools needed for intelligent manufacturing methods with real-time automated process controls. Separate research initiatives address ceramics, metals, polymers, composites, and superconductors. This research supports efforts by U.S. industry to develop reliable, low-cost manufacturing methods for producing tailor-made materials and products with superior properties.UNIVERSITY OF ILLINOIS MATERIALS RESEARCH LABORATORYThe Materials Research Laboratory houses research laboratories and central facilities for 2 major programs: A Department of Energy Materials Science Program, and The University of Illinois portion of the NSF Science & Technology Center for Superconductivity (STCS). It supports interdisciplinary materials research for faculty and students in departments throughout the University. These programs support over 90 faculty members, and in excess of 250 graduate students at the University of Illinois in seven academic departments in the Engineering College and the School of Chemistry.UOP RESEARCH & DEVELOPMENTUOP is the premier organization serving the petroleum refining, petrochemical, and gas processing industries worldwide. Headquartered in Des Plaines, IL, their expertise extends to research & development, process technology, molecular sieves and absorbents, catalysts, specialty chemicals, process plants and equiment, engineering, technical services, and manufacturing. Through the innovation of its employees, UOP holds 25,000 patents worldwide and services more than 5600 process units in more than 100 countries.Materials of Interest to UNICAT MembersMetals and AlloysFunctional Ceramics Polymers Semiconductors Superconductors Catalysts Thin Films Magnetic Materials Bio-Materials Minerals Experimental TechniquesTIME-RESOLVED STRUCTURAL SCATTERINGDiffraction measurements of transient phenomena such as from highly undercooled liquids, or from rapid melting and subsequent crystal growth using the time structure of the APS for nanosecond time-resolution studies.
