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).

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.
