Scatterings

We use small angle scatterings extensively to study the microstructure of soft matter systems listed above. Small angle x-ray scattering (SAXS), small angle neutron scattering (SANS), Grazing Incidence SAXS (GI-SAXS) and light scattering (LS) are good experimental tools to study particle interactions and polymer microstructures. We are also interested in seeing their physical properties; rheological properties are examined with conventional rheometer and Diffusing Wave Spectroscopy (DWS).

In addition, we are collaborating with national labs to study the particle/polymer dynamics employing neutron reflectivity (NR), QENS, NSE and etc.

Our specialty is to characterize the microstructure and dynamics of polymer/colloids-based systems employing SAXS, SANS, NR, QENS and rheo-SAXS. We are currently focusing on the use of Rheo-SAXS for simultaneous observation of structure and rheological properties of soft matter systems.
