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

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.

Advanced Crystallography

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

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).

Near NSF’s ChemMatCARS Users,

Argonne to Restrict User Facility Access for Non-Argonne Users

Argonne National Laboratory is committed to minimizing transmission of COVID-19. While no cases of the virus have been reported on site, we recognize the importance of taking steps to minimize transmission and to accommodate those employees and visitors who are experiencing travel restrictions, school closing or other life changes due to the pandemic.

As such, Argonne is transitioning to an alternate operations model, which includes restricting visitor access to the Lab, including those planning to visit and utilize our User Facilities. This policy takes effect on Tuesday, March 17, 2020.

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) if you have further questions.

In situ visualization of loading-dependent water effects in a stable metal–organic framework

December 02, 2019

Nature Chemistry (2019)

Even for MOFs that are highly stable in humid environments, a static representation of the framework structure may not be sufficient to understand the observed stability. This work has shown that the DMOF-TM framework has a dynamic and reversible structural response to water guest molecules, observed in changes in the unit cell parameters, microstrain, vibrational spectra and atomic structure. These changes manifest themselves at low guest loading and continue to change in response to guest loading.

Nanosheets Synthesis under Mixed Surfactants

October 11, 2019

Chem. Mater. 2019, 31, 21, 9040-9048

Two-dimensional monocrystalline oxide nanomaterials have a great impact on material innovation and property advancement. However, creating them with fine control remains a grand challenge. Inspired by the biomineralization processes, researchers from the University of Wisconsin-Madison were able to synthesize the monocrystalline 2D nanosheets under the mix-charges amphiphilic monolayer. The growth process was monitored by in-situ grazing incidence X-ray diffractions at NSF’s ChemMatCARS.
