Nucleation is the onset of a phase transition, e.g. from liquid to gas, in a small but stable region. In this photo, bubbles in a soft drink each nucleate independently, responding to a decrease in pressure. (Photo courtesy of Wikipedia.)

This course presents a unified treatment of phenomenological and atomistic kinetic processes in materials. It provides the foundation for the advanced understanding of processing, microstructural evolution, and behavior for a broad spectrum of materials. The course emphasizes analysis and development of rigorous comprehension of fundamentals. Topics include: irreversible thermodynamics; diffusion; nucleation; phase transformations; fluid and heat transport; morphological instabilities; gas-solid, liquid-solid, and solid-solid reactions.
