MS-91: Time-resolved phase evolution, interaction & crystallization in soft matter: Integrative approaches

Time:

10:20am - 12:45pm

Session Abstract

This MS will discuss possible interactions among coexistent phases and corresponding impacts on the evolution of phase morphology, distribution, and size, which are barely understood currently, but which, nevertheless, can provide new insights on ordering behaviors. The phase distribution patterns in functional materials are critical in Performance of these products is controlled by a wide range of microstructural feature sizes - from approximately 1 A (phase structure) to hundreds of nanometers and micrometers (grain and voids structures). Microstructures are metastable and can follow unpredictable paths during post-processing. This severely limits application of computer models, the preferred method of optimization. SAXS, SANS, and diffraction of these complex materials, ideally in combination, deliver critically important, quantitative data. This MS will attract talks on metals, ceramics, synthetic biomaterials, polymers manufactured under these industrially relevant conditions.
