Advanced Crystallography

Overview

ChemMatCARS operates three experimental stations in the areas of advanced small-molecule crystallography, liquid surface and interface scattering, and ultra-small to wide-angle scattering at the Advanced Photon Source (APS), the premier undulator-based synchrotron source of high-brilliance high-energy x-rays in the U.S.A. The instrumentation at ChemMatCARS provides information that addresses a broad range of issues in chemistry and materials research.


NSF Award for New Pixel Area Detector to support ChemMatCARS and GSECARS research

Principal Investigator, Mark Schlossman of the University of Illinois at Chicago, and co-principal investigators, IME Pritzker Director, Matthew Tirrell, and Executive Director of CARS, Mark Rivers, were recently awarded a Major Research Instrumentation award from the National Science Foundation (NSF).

This award supports the acquisition and implementation of a state-of-the art cadmium telluride (CdTe) pixel array area detector for advanced X-ray synchrotron applications in the areas of chemical, materials, and earth sciences in ChemMatCARS and GSECARS.

Scientific Focus

The scientific focus of user activities at ChemMatCARS is the study of structure and dynamics over the range of length scales from atomic and molecular to mesoscopic. The experimental techniques available to the scientific community span a spatial resolution of sub-angstrom to micrometer and a time resolution from 50 ns to minutes. These include:

High Precision Crystallography to study charge (i.e., electron) densities, bonding, microcrystals, resonant diffraction, high-pressure (up to 10 GPa) single crystal diffraction, and transient state/photo-crystallography.

Scattering From Liquid Surfaces and Liquid-Liquid Interfaces to measure atomic, molecular, and mesoscopic ordering at interfaces using resonant and non-resonant reflectivity, grazing-incidence diffraction and small angle scattering, surface fluorescence, surface diffuse scattering, and fast techniques, such as grazing incidence diffraction in the 1D pinhole geometry.

Small and wide-angle x-ray scattering (SAXS/WAXS) to probe ordering in bulk materials on angstrom to micrometer length scales.
