Homogeneous asymmetric catalysis offers reliable results and the possibility to 'tune' the catalysis on a rational basis. A pitfall, however, is that the separation of the catalyst from the starting material and products is difficult and often results in the loss of the catalytic material. Immobilization offers a potential solution for the user of enantioselective catalysts in industrial processes and laboratories. Heterogeneous catalysis allows continuous operations, recycling of the catalyst, and an easy separation of the reaction products, reducing both waste and costs. Chemists in academia and industry will welcome this careful selection of topics in this handbook that provides readers with practical and detailed information about the technical requirements for the immobilization of chiral catalysts, their application in synthesis, and methods for recycling.

Raoul De Keyser's mainly abstract art is remarkable for its dimensional realism--that is, its connection of the subjective and objective dimensions of experience. De Keyser personalizes abstraction, he gives it a human face; many of his pictures include motifs drawn from his immediate surroundings or his own personal experience. Instead of searching for an overarching formal principle--as did the pioneers of abstraction from Kandinsky's time through the 1960s--De Keyser attunes his art to the significance of improvisation and chance in all life, and contemporary life in particular. Thus we find in the art of Raoul De Keyser much of the contingency, inconsistency, textual precariousness, modal variety, particularity, unpredictability, disorder and flux that we find in our daily lives. This catalogue, published on the occasion of a touring exhibition of De Keyser's work, documents in sumptuous reproductions the artist's oeuvre over the past twenty years.
