ASM International fosters the understanding and application of metals and engineered materials and their research, design, reliable manufacture, use, and economic and social benefits. This is accomplished via a global information-sharing network of interaction among members in forums and meetings, education programs, and through publications and digital media.
The Minnesota Chapter of ASM International is located in the Twin Cities, Minnesota.

Cryogenic Scanning Electron Microscopy: Exploration of Water-Containing Materials and Dynamic Processes
Scanning electron microscopy (SEM) is a powerful tool for characterizing the microstructure of materials. However, the high resolution of the scanning electron microscope requires high vacuum to control the electron beam and therefore the interior structures of liquids and specimens containing water cannot be imaged due to volatilization. Likewise , imaging a structure that is changing, as in a drying coating, for example, by regular SEM is impossible.
Cryogenic SEM (cryoSEM) meets these challenges. A cryoSEM experiment begins with rapid freezing of the liquid or water-containing specimen to arrest structural development. Then the frozen material is fractured to reveal the interior structure of the specimen and sublimed for contrast. Still frozen, the specimen is then transferred to an SEM equipped with a cryostage and im-aged. CryoSEM has proven to be very useful in exploring the origin of mi-crostructural features in food products, biological specimens and materials. In addition to introducing the technique and the new state-of-the-art cryoSEM facility at the University of Minnesota, this presentation will include examples the application of cryoSEM in exploring the microstructure of liquid applied coatings.
