The objective of this workshop is to discuss ways to characterize complex materials using scattering techniques. The materials include,zeolites, manganites and glasses and experimental techniques include x-ray and neutron scattering, XAFS etc. Computer simulations play an important role in incorporating the known local stereochemistry with the experimental results to produce a more complete description of the structure, including structural disorder that is often present. Participation is by invitation only and is capped at 30 people. The sessions will include introductory lectures and also informal discussions.
