1. Structural, Electronic and Reactive Properties of Pentapyridyl - Base Metal Complexes : Relevance for Water Oxidation Catalysis
Sammanfattning : The rationalization of chemical-physical proprieties of transition metal complexes is fundamental in order to understand and tune their reactivity. In this thesis, a systematic investigation of the geometrical and electronic properties of [M(Py5OH)Cl]+ complexes (M= Mn, Fe, Co, Ni) has been performed, and their ability to act as molecular water oxidation catalysts has been probed.

2. Studies of second coordination sphere effects and metal variations on [FeFe]-hydrogenase mimics
Sammanfattning : Mitigation of climate change motivates researchers to explore hydrogen as a potential energy carrier. Unfortunately, widespread use of hydrogen as an energy carrier is limited by numerous challenges in its production, including high energy consumption; high economic cost; current reliance on rare metals such as platinum.

3. The Far-Red Limit of Photosynthesis
Sammanfattning : The photosynthetic process has the unique ability to capture energy from sunlight and accumulate that energy in sugars and starch. This thesis deals with the light driven part of photosynthesis. LÄS MER
4. Towards renewable chemicals production in cyanobacteria
Sammanfattning : The intensive fossil fuel combustion by humanity resulted in the increase of atmospheric CO2 concentration creating the greenhouse effect, which in turn causes severe environmental problems. Thus, humanity should find solutions to decrease dependency on fossil hydrocarbons in order to lower CO2 emission into the atmosphere. LÄS MER
5. New Roads for an Ancient Enzyme : Whole-Cell Studies and New Cofactors for [FeFe] Hydrogenases
Sammanfattning : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. LÄS MER
