Tutorial I: Sample Environments for Soft Matter Processing


  • Matthew E. Helgeson, University of California, Santa Barbara
  • Lilo Pozzo, University of Washington
  • Norman Wagner, University of Delaware

Recent developments in new sample environments for SANS have opened up a wide range of new experiments to examine the dependence of soft matter morphology and microstructure on various types of processing including flow, applied fields, compositional changes and extreme state changes. Furthermore, the emergence of time-resolved SANS measurements through process cycling builds upon these capabilities toward experiments aimed at elucidating structural evolution during real and simulated industrial processing conditions. This tutorial will provide an overview of these important new advances, and highlight some of the resulting exciting science and engineering on a range of soft materials including polymers, colloids, biomaterials and surfactants. We will also highlight the strong coupling of these new experimental capabilities with data analysis methods, which require the development and use of sophisticated modeling in order to handle the complexities of the data including structural anisotropy, polydispersity and time variation. The tutorial will conclude with a panel discussion aimed at researchers interested in developing new sample environment capabilities in collaboration with neutron scattering facilities. As such, we anticipate attendance by researchers from a wide range of backgrounds interested in the processing of soft materials and complex fluids.

Tutorial II: Neutron Spectroscopy Techniques for Magnetic Materials and Single Crystal Characterization


  • Kate Ross, Colorado State University
  • Jose A. Rodriguez-Rivera, National Institute of Standards and Technology

The study of novel solid state materials at the atomic scale is fundamental to efforts to model and understand their properties. Elucidating the interactions between atoms and molecules is central to the search for materials with higher temperature superconducting, greater information storage densities, and faster computers. Neutron spectroscopy is an essential and powerful technique with which to understand these interactions through measurements of the underlying atomic and magnetic order as well as the associated dynamics. This tutorial will explain how to use neutron scattering to study magnetic materials with experimental examples.
