1. 1. Biomimetic Reactions : Water Oxidation and Aerobic Oxidation

   Författare :Lien-Hoa Tran; Björn Åkermark; Nina Kann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis deals mainly with two oxidation reactions: water oxidation and aerobic oxidation, both of which have been applied in a biomimetic fashion. In the former reaction molecular oxygen is generated whereas in the latter it was used as terminal oxidant in oxidation reactions. LÄS MER

3. 2. Biomimetic Membranes: : Molecular Structure and Stability Studies by Vibrational Sum Frequency Spectroscopy

   Författare :Jonathan F.D. Liljeblad; Mark W. Rutland; Magnus C. Johnson; Tore Brinck; Lars Kloo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrational Sum Frequency Spectroscopy VSFS ; Langmuir monolayer; LB depositon; phospholipids; oxidation; biomimetic membranes; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : In the research presented in this licentiate thesis the surface specific technique Vibrational Sum Frequency Spectroscopy, VSFS, combined with the Langmuir trough has been utilized to investigate Langmuir monolayers and Langmuir-Blodgett (LB) deposited mono- and bilayers of phospholipids. Their molecular structure, stability, and hydration were probed to gain additional understanding of important properties aiming at facilitating the use of such layers as model systems for biological membranes.

4. 3. Catalysts for Oxygen Production and Utilization : Closing the Oxygen Cycle: From Biomimetic Oxidation to Artificial Photosynthesis

   Författare :Erik Karlsson; Jan-Erling Bäckvall; Björn Åkermark; Jerker Mårtensson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxygen; catalytic oxidation; biomimetic oxidation; artificial photosynthesis; water oxidation; DFT calculations; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis describes the development and study of catalysts for redox reactions, which either utilize oxygen or hydrogen peroxide for the purpose of selectively oxidizing organic substrates, or produce oxygen as the necessary byproduct in the production of hydrogen by artificial photosynthesis.The first chapter gives a general introduction about the use of environmentally friendly oxidants in the field of organic synthesis, and about the field of artificial photosynthesis.

5. 4. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 : Catalyst Immobilization in Ionic Liquid for H2O2 Oxidations

   Författare :Auri Lindén; Jan-Erling Bäckvall; Peter Somfai; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomimetic; oxidation; catalysis; ionic liquid; hydrogen peroxide; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. LÄS MER
