Materials

Oak Ridge National Laboratory (ORNL) in cooperation with the U.S. Department of Energy conducts a broad range of theoretical and computational research in materials sciences. This work is tightly integrated with experimental programs and is committed to making effective use of modern theory and advanced computation to progress core science and technology. Efforts include a full range of theory activities, ranging from basic science aimed at providing the fundamental understanding and basis for long term solutions to our energy problems, to near term work addressing our nation's most pressing energy and security needs.

Neutron scattering characterizes dynamics in polymer family

Understanding the interplay between structure and dynamics is the key to obtaining tailor-made materials. In the last few years, a large effort has been devoted to characterizing and relating the structure and dynamic properties in families of polymers with alkyl side groups. Now...
