Geophysical and Geochemical Sciences (GeoCARS)
Soil and Environmental Sciences (SoilEnviroCARS)
GeoSoilEnviroCARS (or GSECARS, Sector 13) research furthers knowledge of the composition, structure, and properties of earth and planetary materials and the processes they control. Experiments involve high pressure research using both the diamond anvil cell and the large volume press; X-ray diffraction and scattering and X-ray absorption spectroscopy from earth and planetary materials; and X-ray fluorescence microprobe analysis and microtomography. GSECARS is funded by the U.S Department of Energy and the National Science Foundation as a national resource for the entire community in these scientific areas in the United States. GSECARS is affiliated with the American Geophysical Union through its Committee on Mineral and Rock Physics and the Soil and Environmental Sciences.


Structural Biology
BioCARS (Sector 14) serves a community of structural biologists with special interest in protein and virus crystallography and time-resolved diffraction. Typical experiments involve crystallographic studies of viruses, ribosomes, and other complexes with very large unit cells; studies of small crystals; time-resolved crystallography; and scattering from less-ordered biological systems. In all cases, the goal is to understand basic biological processes in structural terms, a goal fundamental to the pharmaceutical and biotechnology industries as well as to basic biomedical science. BioCARS is funded by the National Center for Research Resources of the National Institutes of Health to serve as a national resource for the structural biology community.


Chemistry and Material Science
ChemMatCARS (Sector 15) represents chemists and material scientists with interests in surface science, advanced crystallography, nanoscience, and the science of soft materials and polymers. Research at ChemMatCARS focuses on several aspects of dynamic and structural condensed matter and materials chemistry research. Areas include surface and interfacial properties in soft condensed matter and molecular liquids; chemical crystallography; structure and properties of molecular aggregates and semiconductors in microporous, layered and glassy materials; interfacial and bulk properties of novel polymers and composites, including supramolecular and mesoscopic structures; and local structure in metalloproteins and enzymes. ChemMatCARS is funded by the National Science Foundation and the U.S. Department of Energy as a national chemistry and materials research facility.
