Objectives
Many complex molecular systems (synthetic or natural) are used, in low concentration, to control functions such as detergency, coating capability, anti-icing, therapeutic targeting, ... by giving a very strong response to a very weak control signal (electrical, mechanical, thermal). These technologies are based upon of a strong state of division of matter giving large interfaces between immiscible liquids or between solid and liquids. The aim of the course is to present the fundamental processes governing the dynamics state of matter called "colloidal" state and to understand the physicochemical and rheological properties of common objects (lubricants, drugs, food, cosmetics, paints, cells. ) in variable applications ranging from biotechnology to civil engineering.
