1. Mimicking Nature – Synthesis and Characterisation of Manganese Complexes of Relevance to Artificial Photosynthesis
Sammanfattning : The development of efficient catalyst for water oxidation is of paramount importance to artificial photosynthesis, but before this can be achieved a deeper understanding of this reaction is essential. In nature this reaction occurs in a tetranuclear Mn-cluster which serves as the work-horse of oxygenic photosynthesis. LÄS MER
2. 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
3. The birth of the hydrogenase : Studying the mechanism of [FeFe] hydrogenase maturation
Sammanfattning : The [FeFe] hydrogenases are ancient metalloenzymes that catalyse the reversible interconversion between protons, electrons and molecular hydrogen. Despite the large structural variability within the [FeFe] hydrogenase family, the active site, the so called “H-cluster” is present in every representative. LÄS MER
4. 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.

5. Wood Templated Organic Electronics
Sammanfattning : In today’s digital era, electronics are integral to most activities in our daily lives, offering swift and global communication, powerful data processing tools, and advanced sensor devices. However, there are drawbacks to the exponentially growing demand for electronics, such as the depletion of fossil resources, and the complexities surrounding recycling electronic waste (E-waste).
