NTNU Physics Department Clays represent one of the traditional materials, whose applications have played an important role throughout human history. A list of keywords in this context include building materials, ceramics, rheology modification, catalysis, paper filling, oil well -drilling and -stability, etc. Clays as geological materials have been widely studied and discussed by geologists, geo-chemists, geophysicists, etc, and modern industrial uses of clays are based on this history and knowledge. However, studies and resulting applications of clays beyond these traditional approaches and disciplines, are merely in its infancy. For example, one may observe that physicists in particular until recently apparently have not regarded clays as "interesting and accessible" experimental and theoretical model systems. With the availability of clean chemistry customized synthetic clays, this is changing, and there is presently a growing scientific activity associated with including clays into modern materials science together with other synthetic and complex adaptive materials such as colloids, polymers, liquid crystals, bio materials, etc. In this talk these points will be illustrated by means of selected recent experimental and theoretical findings on model system synthetic clays.
