1. Immobilisation of Ru-Based Molecular Catalysts for Electrochemical Water Oxidation
Abstract : Artificial photosynthesis requires catalysts for efficient and selective conversions of small molecules. Molecular catalysts are advantageous to use in these instances as they offer precise control over chemical reactivity. READ MORE

2. Design of Cellulose-based Materials by Supramolecular Assemblies
Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

3. Improving Tröger's Base Chemistry : Developing the Chemistry of Tröger's base
Abstract : The Tröger’s base framework has been implemented in two different receptors. The first of these receptors, incorporating two 18-crown-6 moities, was used as a host in a binding study together with a sieries of bisammonium salts that yielded different binding constants that were then used as a benchmark to compare different computational methods (Molecular Mechanics (MM) and Density Functional Theory (DFT)) in predicting the correct results where the MM methods proved more effective.

4. (Photo)electrochemical Water Oxidation: From Catalysis to Functional Device
Abstract : The key challenge within artificial photosynthesis is achieving efficient electro- or photo-driven water oxidation catalysis, a necessary process to supply the protons for the reduction reactions, thereby enabling solar fuel production. To facilitate efficient water (photo)electrolysis for solar fuel production, this thesis focuses on two aspects: 1) elucidating the O-O bond formation mechanism and developing efficient, stable, and economical water oxidation catalysts (WOCs); 2) exploring stable, low-cost, light-absorbing photoanode materials that have suitable band structures and excellent charge diffusion properties.

5. Investigating cellulose structure using solid-state NMR spectroscopy
Abstract : Cellulose is the most abundant polymer in nature and it is an important constituent in most flowers, trees, and even some animals. Cellulose has an established use in many important products, such as textile fibers, paper and paperboard, and recently new applications have received increased attention. READ MORE
