3. Physical chemistry of nanodispersed systems and polymer solutions Objectives of the course: The course aims to provide the physical chemistry background necessary for explanation of phenomena and processes taking place in the nanoscale – in colloids, micellar systems and polymer solutions and the achievement of skills of the computer modelling and experimental studies of processes in nanoscales. The course contains selected ideas, laws, models and theories necessary to understand the basic nanotechnology problems. Synonyms: physics of mesoscale introduction to nanotechnology soft matter physics
