This course with cover fundamental principles related to interactions, dynamics, and structure in colloidal and interfacial systems. Concepts covered include Fluid Interfaces and Capillarity, Brownian motion, diffusion, sedimentation, electrophoresis, colloidal and surface forces, polymeric forces, aggregation, deposition, and experimental methods. Modern topics related to colloids in nano- science and technology will be discussed throughout the course with frequent references to recent literature. Students with research topics in colloids, polymers, biomaterials, nanoscience and nanotechnology will be beneficial from the lectures of this course.
