The Dale E. Sayers papers document Sayers' career as a researcher and educator, from his work as an undergraduate at the University of California at Berkeley to his teaching and research career as a professor of physics at North Carolina State University. Sayers was a co-developer of the modern extended x-ray absorption fine structure (EXAFS) technique, which, according to Sayers, "allows atomic structural information to be determined in complex systems." In addition to EXAFS, his research interests included x-ray absorption spectroscopy, amorphous materials, mammography technology, synchrotron radiation, and environmental science. Sayers' extensive planning work on the NC STAR Storage Ring Project (North Carolina Storage Rings for Advanced Research) is one of the main subjects documented here. Other research project files included in these papers are Joint Economic Development Initiative - Advanced Light Technologies (JEDI-ALT) and the Department of Defense's Technology Reinvestment Project (TRP). These research files also include information on Sayers involvement in projects with the National Synchrotron Light Source (NSLS), the Advanced Light Source (ALS), the Canadian Light Source (CLS), Brookhaven National Laboratory (BNL), and MEMS (Microelectromechanical Systems). Sayers was active professionally in and beyond N.C. State. He published more than 200 articles in journals such as Environmental Science and Technology, Journal of Applied Physics, Journal of Materials Research, Journal of Synchrotron Radiation, and Thin Solid Films. He was active in organizations such as International XAFS Society and the American Physical Society, was awarded a patent on his "Stable Silicide Electrical Contacts on Si" invention, presented invited talks and seminars at more than sixty national and international conferences, and served as a consultant for groups such as Mobil Research and Development. During his tenure at N.C. State, Sayers was involved in grant projects with institutions such as Exxon, the Massachusetts Institute of Technology, the National Science Foundation, the Office of Naval Research, Procter & Gamble, the United States Department of Agriculture, the United States Department of Energy, and the University of Connecticut. Included in this collection are papers from Sayers' colleague Rodney McCormick, also of the NC State Physics Department. Dale Edward Sayers began his studies at the University of California at Berkeley, where he received his bachelor's degree in physics. He continued his studies at the University of Washington, where he completed his master's and doctoral degrees in physics. Sayers was named assistant professor of physics at North Carolina State University in 1976, associate professor in 1979, and professor in 1984. He served in that capacity until his death, November 25, 2004. Less

Stanley Backer (1920-2003) attended the Massachusetts Institute of Technology, earning degrees in engineering and textile technology. He joined the faculty at M.I.T. in 1951 and eventually became the head of the Fibers and Polymers Laboratory. His research in textiles engineering led to a greater understanding of fiber structure and fabric behavior. Backer also led a program to develop one of the first online information retrieval systems, known as the Textile Information Retrieval Product. He died in 2003. Stanley Backer's papers consist of articles, books, papers, theses and other material reflecting his textile engineering research while attending and teaching at the Massachusetts Institute of Technology. A Research Files series contains collected information on fabric mechanics, texturing, and other topics. The Massachusetts Institute of Technology Special Program series contains material on programs in which Backer had participated. The Supervised Theses series includes those supervised by Backer while a professor at M.I.T. A series of Backer's published works is also included, as well as a list of his collected works. Less
