NSF’s ChemMatCARS

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 Hightlight

Competing Absorption of Surfactants and Antibodies to the Water Surface

Science Hightlight

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, June 17, 2020

Dear NSF’s ChemMatCARS Users,

2020-2 cycle started on June 10, and on June 15, the APS transitioned to Limited Operations from Minimum Safe Operations. In this operations mode, the scope of work has been expanded to include some limited in-situ experiments in addition to mail-in/remote access experiments involving low-risk and most medium-risk samples, as defined on the ESAF form. Onsite access remains prohibited for internal or external users for majority of beamlines at APS, including ChemMatCARS beamline, and each beamline is limited to one staff member onsite at a time per 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

Since the start of the 2020-2 cycle, NSF’s ChemMatCARS has been operating under the APS guideline and performing mail-in/remote access experiments that are feasible in this operations mode. Please contact your beamline scientist contacts (Dr. Yu-Sheng Chen, Dr. Wei Bu and Dr. Mrinal) 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).
