What’s New @ CNMS


Small Angle X-ray Scattering (SAXS)


Small Angle X-ray Scattering (SAXS) is an analytical method to determine the structure of particle systems in terms of averaged particle sizes or shapes. The materials can be solid or liquid and they can contain solid, liquid or gaseous domains of the same or another material. The method is accurate, non-destructive and often requires only a minimum of sample preparation. The concentration ranges between 0.1 wt.% and 99.9 wt.%. The particle or structure sizes that can be resolved range from 1 to 50 nm in a typical set-up but can be extended to larger angles than between the typical 0.1° and 10° of SAXS, through simultaneous collection of Wide-Angle X-Ray Scattering (WAXS) data. The CNMS has recently added an Anton Paar SAXSess spectrometer to expand our nanoscale characterization capabilities. This new instrument features both SAXS and WAXS data collection, and a range of sample stages to enable SAXS studies on powders, liquids, solids, and thin films. Non-ambient options include controlled temperature and humidity cells, flow cells, and grazing-incidence SAXS for in-plane characterization of thin films.


ORNL Guest House construction - update

The exterior hasn’t changed much lately – we can see progress on the interior through the windows! We anticipate opening in early Summer!
