The term zeolite is based on Greek words for "to boil" and "stone" and it is already known since more than 250 years. At that time, the Swedish mineralogist A.F. Cronstedt (1722-1765) observed the formation of large amount of steam when heating the material Stilbite pointing to his porous character and adsorption capacity. At present, over 200 different zeolite frameworks have been identified. In general, zeolites are crystalline aluminosilicates with defined micropore structure. Within zeolites, a good number of elements can be isomorphously incorporated and much more elements or their oxides can be hosted by zeolites. Besides their big variety in size of pore mouths, channels, crossings etc. leading also to their designation as molecular sieves and uses in membrane applications, zeolites reveal BrOnsted and Lewis acidic properties that can be varied in wide limits as well. Thus, they deserve the name "solid acids." Zeolites have an immense importance in diverse industrial applications as catalysts and adsorbents, for example in refinery industry, chemical industry, detergent sector or for solar thermal collectors and adsorption refrigeration In this special issue we aim at new developments and recent progress with respect to zeolite-catalyzed chemical reactions, adsorption applications and membrane uses as well as improved syntheses strategies and characterization techniques.

Nonstandard analysis was originally developed by Robinson to rigorously justify infinitesimals like df and dx in expressions like df/dx in Leibniz' calculus or even to justify concepts like delta-`functions'. However, the approach is much more general and was soon extended by Henson, Luxemburg and others to a useful tool especially in more advanced analysis, topology, and functional analysis. The book is an introduction with emphasis on those more advanced applications in analysis which are hardly accessible by other methods. Examples of such topics are a deeper analysis of certain functionals like Hahn-Banach limits or of finitely additive measures: From the viewpoint of classical analysis these are strange objects whose mere existence is even hard to prove. From the viewpoint of nonstandard analysis, these are rather 'explicit' objects. Formally, nonstandard analysis is an application of model theory in analysis. However, the reader of the book is not expected to have any background in model theory; instead knowledge of calculus is required and, although the book is rather self-contained, background in more advanced analysis or (elementary) topology is useful.
