Soft Materials Characterization Laboratory
Anna Kiyanova, Paul F. Nealey, Doug Weibel
This NSEC sponsored facility has filled a critical need on Campus for characterization of soft materials and Polymers:

*Differential Scanning Calorimeter
*Thermo Gravimetric Analysis
*Schlenk lines for polymer synthesis (anionic, others)
*Zeta Potential Analyzer, Spin coater/vacuum ovens/photo crosslinker.
Impact: The SML is used heavily by biomedical researchers (membranes, artificial tissue). Polymer and liquid crystal researchers. New this year are 2 groups from Engineering Physics looking at phase transitions in inorganic materials.
Growth: In one year, patrons increased from 3 groups with seven students to 11 groups with 26 users, and 3 industrial companies.
Future Expansion of SML Capability:
The measurement of mechanical properties and fictionalization of nano scale materials (including elasticity, molecular (un)folding, ligand-receptor interactions, etc.) is of growing interest to our researchers and industrial partners. The laboratory will acquire a BIO-AFM in 2009 to enable such studies (figure 2)
