Dedicated to static and dynamic condensed matter chemistry and materials science.

Advanced Crystallography

Uses a "rapid setup" crystallography facility that allows us to rapidly switch operation to the single-crystal instrument.

Liquid Surface/Interface X-ray Scattering

Used to investigate dynamical and structural properties of surfaces and interfaces in a variety of liquid and solid systems.

Anomalous Small Angle X-ray Scattering (ASAXS)

Focuses on element specific structural study of soft-matter in nano-dimensions.

Science Highlights

Two- and Three-Dimensional Assembly of Anisotropic Gold Nanoparticles

Science Highlights

Materializing rival ground states in the barlowite family of kagome magnets: quantum spin liquid, spin ordered, and valence bond crystal states. 

Update on Status at NSF’s ChemMatCARS, August 19, 2020

Dear NSF’s ChemMatCARS Users,

2020-3 cycle will start on October 1 and APS plans to move to Limited Operations Plus mode. In this operations mode, only mail-in/remote access experiments, including some limited in-situ experiments, are feasible. 

Onsite access remains prohibited for external users for majority of beamlines at APS, including ChemMatCARS beamline. Please see the announcement on the APS home page at www.aps.anl.gov or the User Info page at www.aps.anl.gov/Users-Information

Please contact your beamline scientist contacts (Dr. Yu-Sheng Chen, Dr. Wei Bu and Dr. Mrinal Bera) to discuss the compatibility of your experiments in this operations mode.

Recent Publications

NSF’s ChemMatCARS operates three experimental stations in the areas of advanced small-molecule crystallography, liquid surface and interface scattering, and 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 NSF’s ChemMatCARS provides information that addresses a broad range of issues in chemistry and materials research. NSF’s ChemMatCARS is supported by the Divisions of Chemistry (CHE) and Materials Research (DMR), National Science Foundation, under grant number NSF/CHE-1834750. Construction of a second beamline at NSF’s ChemMatCARS is supported by NSF grant CHE-1836674 with contributions from the Office of Multidisciplinary Activities within the Directorate of Mathematical and Physical Sciences and NSF Divisions in Chemistry (CHE), Molecular and Cellular Biology (MCB), and Chemical, Bioengineering, Environmental, and Transport Systems Engineering (CBET).
