Category Conferences - Seminars
Advances in materials increasingly rely on the 3-D characteristics of its microstructure and chemistry at the nanoscale.  This presentation will review 3-D imaging techniques that measure microstructural properties, and discuss its influence on material function and reliability. The presentation will then focus on three-dimensional microstructural imaging methods for energy materials. The use of a novel imaging technique, synchrotron-based transmission x-ray microscopy, will be demonstrated by characterizing structural and chemical changes in fuel cell and gas separation membrane materials. Challenges and opportunities for future work will then be discussed.

The goal of this research will be to obtain a scientific and engineering understanding into how micro- and nano-structure induced transport mechanisms govern performance, with a long-term goal to improve current materials and create new materials that will enable improved device performance and increased long-term reliability for advanced engineering applications.
