Physical chemistry of adsorption and catalysis

Like literature, philosophy is not distinguished from other subjects by a specific approach to a subject-matter independent of it. Chemistry deals with chemicals, biology with life and astronomy with very large, very distant objects. Philosophy can boast no such definite subject-matter.

Due to economic and ecological factors, catalytic processes in the pro duction of fine chemicals are gaining in importance, especially in the area of asymmetric catalysis (Collins et al. 1997; Breuer et al. 2004). Accordingly, the practicing chemist has three major options: transition metal catalysts (Jacobsen et al. 1999), organocatalysts (Berkessel and Gröger 2004) or enzymes (Drauz and Waldmann 2002; Liese et al. 2006). All of them have advantages and disadvantages, which means that a given type of catalysis cannot be expected to provide general so lutions to all problems of relevance in academic and industrial labora tories. Therefore, research in all three approaches needs to be intensified.

Modern warfare, we discovered, was to a far greater extent than ever before a conflict of chemists and manufacturers. Manpower, it is true, was indispensable, and generalship will always, whatever the conditions, have a vital part to play. But troops, however brave and well led, were powerless under modern conditions unless equipped with adequate and up-to-date artillery (with masses of explosive shell), machine-guns, aircraft and other supplies. Against enemy machine-gun posts and wire entanglements the most gallant and best-led men could only throw away their precious lives in successive waves of heroic martyrdom. Their costly sacrifice could avail nothing for the winning of victory.
