Mission
To use small and wide angle scattering to study condensed matter at length scales ranging from angstroms to hundreds of nanometers.
Areas of Interest
• Colloids & suspensions
• Composite materials
• Crystallization
• Fiber structure and processing
• Polymers
• Self-assembly of nanoparticles
SAXS vs.WAXS
Both Small Angle X-ray Scattering -SAXS- and Wide Angle X-ray Scattering -WAXS- are available at ChemMatCARS.
The major difference in the two probes is related to the mechanism producing the scattering.
SAXS arises from inhomogeneous electron density on different length scales ranging from angstroms to microns.
WAXS arises more specifically from regular, periodic variations of electron density over length scales that are large compared to the repeat distance.
