Chemically-Enhanced Motion by Curvature by Professor Paul Fife University of Utah JTB 320, 3:20pm Monday, November 3, 1997 Abstract Interfaces between solid phases in a material often migrate, due to chemical action localized at the interfaces. Models developed by Cahn, Fife, and Penrose account for the motive force for this migration in terms of the concentration of a "solute" substance and the curvature of the interface. The solute can diffuse along the interface, but not elsewhere. The derivation and progress in the analysis of these models will be presented. (Joint with the above authors plus Elliott.)
