Applications of solid-state NMR include (1) structural elucidation of solid materials, such as crosslinked polymers, gels, zeolites, and natural organic matter; (2) morphology and organization of heterogeneous materials, such as semicrystalline polymers, photovoltaic polymers, and composites; and (3) molecular dynamics and interactions. The information content obtained from ssNMR is highly complementary to that from microscopy and scattering techniques.

This course provides a comprehensive understanding of polymer decomposition and degradation, covering thermal and chemical degradation, biological decomposition, and other mechanisms. The knowledge and discussion gained in this course are essential for designing sustainable polymers.

Freshwater ecosystems provide important services and harbor unique biota; however, watershed degradation, species invasion, and poor management have led to imperilment of freshwater rivers, lakes, and wetlands, and a global freshwater biodiversity crisis. In this seminar, we will read and discuss recent scientific literature related to threats, conservation, and restoration of freshwater ecosystems (streams, lakes, wetlands) and biota.
