21. Enantioselective Synthesis of Sec-Alcohol Derivatives and Diols via Combined Ruthenium and Enzyme Catalysis
Sammanfattning : The first part of this thesis describes the synthesis of enantiopure secondary alcohol derivatives. These syntheses are carried out via the combination of an enzyme as a resolution catalyst and a ruthenium catalyst as a racemization catalyst, in what is called dynamic kinetic resolution (DKR).

22. Stepping into Catalysis : Kinetic and Mechanistic Investigations of Photo- and Electrocatalytic Hydrogen Production with Natural and Synthetic Molecular Catalysts
Sammanfattning : In light of its rapidly growing energy demand, human society has an urgent need to become much more strongly reliant on renewable and sustainable energy carriers. Molecular hydrogen made from water with solar energy could provide an ideal case. LÄS MER
23. The Importance of Being Promiscuous : Understanding enzyme function, specificity, and evolution through structure
Sammanfattning : Enzymes are known to be amazingly specific and efficient catalysts. However, many enzymes also have so-called promiscuous functions, i.e., they are able to catalyze other reactions than their main one. LÄS MER
24. Aliphatic Polyesters for Soft Tissue Engineering : Development from Conventional Organometallic to Novel Enzymatic Catalysis
Sammanfattning : The development of macromolecules with defined structure and properties, aimed specifically for biomedical applications, has resulted in diverse biodegradable polymers with advanced architectures. Among them, aliphatic polyesters synthesized by ring-opening polymerization (ROP) of lactones and lactides have a leading position due to their good mechanical properties, hydrolyzability and biocompatibility.

25. Immobilizing catalysts on textiles : case of zerovalent iron and glucose oxidase enzyme
Sammanfattning : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. LÄS MER
