The dominant research interest of the Queen's University Small
Angle X-ray Scattering (SAXS) Laboratory involves the study of microstructure
and dynamical processes in polymer materials, both in 2-D (film) and 3-D (bulk)
forms. This is primarily an experimental project utilizing scattering
techniques to probe the unique self ordering seen in block copolymer materials
at nanometer length scales. An
active collaboration with the Department of Materials and Metallurgical
Engineering (Queen's University) applying SAXS methods to the study of
nanostructure in aluminum alloys is also in progress.
Measurements are done using an in-house small angle x-ray
scattering apparatus as well as off-site facilities, such as the Cornell High
Energy Synchrotron Source of Cornell University and the National Synchrotron
Light Source of Brookhaven National Laboratory (Long Island, NY). Past
synchrotron SAXS measurements have also been performed at the Laboratorio
Nacional de Luz Sincrotron (Campinas, Brazil) and the European Synchrotron
Radiation Facility (Grenoble, France).
