CK204V Surfaces, Colloids and Soft Matter 5.0 credits

The course is online with a series of pre-recorded lectures, with periodic zoom "tutorials". We will address a broad range of surface and colloidal principles and see how these are applied, for example in cosmetics, recycling, detergency, food technology and pharmaceuticals. Some of the sustainability issues we face in this discipline and their solutions form a continuous theme. We will discuss the surface science of nature – how nature solves such challenges as water harvesting by beetles in the desert, how geckos stick to the ceiling and the lotus leaf effect.
