Kurzbeschreibung
This book discusses the fundamental processes at work in mechanical catalysis, the origin of its general and physical features, the way it has evolved in many enzymes, and how it relates to catalysis in man-made systems. It ties together the thirty-plus existing theories of enzymatic catalysis, covers design issues in the creation of biomimetic catalysts (including requirements, problems, approaches, and solutions), explains the difference between energy- and time-dependent catalysis, and interfaces with the hot ideas of complexity and complex systems science. This book has large implications and could revolutionize our understanding of catalysis.

GLOSSARY.

1. Introduction to Thermodynamic (Energy-Dependent) and Mechanical (Time-Dependent) Processes: What Are They and How Are They Manifested in Chemistry and Catalysis? (Gerhard F. Swiegers).

2. Heterogeneous, Homogeneous, and Enzymatic Catalysis. A Shared Terminology and Conceptual Platform. The Alternative of Time-Dependence in Catalysis (Gerhard F. Swiegers).

3. A Conceptual Description of Energy-Dependent ("Thermodynamic") and Time-Dependent ("Mechanical") Processes in Chemistry and Catalysis (Gerhard F. Swiegers).

4. Time-Dependence in Heterogeneous Catalysis. Sabatier's Principle Describes Two Independent Catalytic Realms: Time-Dependent ("Mechanical") Catalysis and Energy-Dependent ("Thermodynamic") Catalysis (Gerhard F. Swiegers).

5. Time-Dependence in Homogeneous Catalysis. 1. Many Enzymes Display the Hallmarks of Time-Dependent ("Mechanical") Catalysis. Nonbiological Homogeneous Catalysts Are Typically Energy-Dependent ("Thermodynamic") Catalysts (Robin Brimblecombe, Jun Chen, Junhua Huang, Ulrich T. Mueller-Westerhoff and Gerhard F. Swiegers).

6. Time-Dependence in Homogeneous Catalysis. 2. The General Actions of Time-Dependent ("Mechanical") and Energy-Dependent ("Thermodynamic") Catalysts (Robin Brimblecombe, Jun Chen, Junhua Huang, Ulrich T. Mueller-Westerhoff, and Gerhard F. Swiegers).

7. Unifying the Many Theories of Enzymatic Catalysis. Theories of Enzymatic Catalysis Fall into Two Camps: Energy-Dependent ("Thermodynamic") and Time-Dependent ("Mechanical") Catalysis (Gerhard F. Swiegers).

8. Synergy in Heterogeneous, Homogeneous, and Enzymatic Catalysis. The "Ideal" Catalyst (Gerhard F. Swiegers).

9. A Conceptual Unification of Heterogeneous, Homogeneous, and Enzymatic Catalysis (Gerhard F. Swiegers).

10. The Rational Design of Time-Dependent ("Mechanical") Homogeneous Catalysts. A Literature Survey of Multicentered Homogeneous Catalysis (Junhua Huang and Gerhard F. Swiegers).

11. Time-Dependent ("Mechanical"), Nonbiological Catalysis. 1. A Fully Functional Mimic of the Water-Oxidizing Center (WOC) in Photosystem II (PSII) (Robin Brimblecombe, G. Charles Dismukes, Greg A. Felton, Leone Spiccia, and Gerhard F. Swiegers).

12. Time-Dependent ("Mechanical"), Nonbiological Catalysis. 2. Highly Efficient, "Biomimetic" Hydrogen-Generating Electrocatalysts (Jun Chen, Junhua Huang, Gerhard F. Swiegers, Chee O. Too, and Gordon G. Wallace).

13. Time-Dependent ("Mechanical"), Nonbiological Catalysis. 3. A Readily Prepared, Convergent, Oxygen-Reduction Electrocatalyst (Jun Chen, Gerhard F. Swiegers, Gordon G. Wallace, and Weimin Zhang).

Appendix A Why Is Saturation Not Observed in Catalysts that Display Conventional Kinetics?
