Electrokinetic phenomena, zeta potential, Henry equation, Hückel and Smoluchowsky approximations.Self-assembly phenomena in thermodynamically and kinetically stable systems.

Role of charged interphases in the phenomena of coagulation, flocculation, or stability of disperse systems (kinetic stability) Diffusion coefficient, Stokes-Einstein equation, intermolecular forces role in stability of kinetically stable systems. Rheological properties: Brownian motions in different types of fluids: viscosity and kinetic aspects.

Intermolecular Forces: Electrical double layer, van der Waals forces, DLVO theory.

Phenomenological aspects as discontinuity at interphases, superficial excess, surface tension, adsorption phenomena, phenomena of adhesion, wettability and spreading. Phenomena and parameters to describe solid-gas, solid-liquid, liquid-gas, liquid-liquid interfacial properties.

Interphases Colloids and Surfaces Nanostructures in the fluid phase.

The concepts and knowledge learned by the students will give them the ability to understand the behavior of real (colloidal, nanophasic and biological) systems and of emerging scientific issues (nanoscience and nanotechnology), and the curiosity to explore these subjects by individual study on specialized texts and scientific papers. The course aims to develop the ability to present in a concise and comprehensive way a scientific subject both in written (scientific report) and oral (seminars) form also through the use of computer media (PowerPoint presentations). The course is focused on developing the knowledge and ability to interpret data in a critical way to frame every argument in its scope, knowing then find the appropriate way for its consideration, or resolution. The student will acquire the theoretical knowledge and the practical skills to characterize and understand the evolution of colloidal, nano-structured, and macromolecular systems, and predict their stability.

In addition, students will gain basic knowledge about the phenomena of self-association of surfactants and their role in the preparation of complex formulations. Role of the interphases in real systems, in particular the stability, the phenomenological aspects, and specific interactions at the molecular level.
