Cover: Liquid Crystal Phases

Binary phase diagrams are an important component of many materials science and physical chemistry courses. In Liquid Crystal Demonstration of Binary Phase Behavior for the Classroom, Marissa E. Tousley presents a classroom demonstration that allows students to observe phase behavior as a function of composition and temperature. This demonstration uses surfactants that self-assemble into ordered structures (lyotropic liquid crystalline phases) with unique optical properties in the presence of water. The cover shows images taken at different time points during a temperature-induced phase transition. Different liquid crystal phases exhibit different optical properties, making it possible to observe phase behavior using an optical microscope.
