1. Transition metal oxide surfaces : Surface structures and molecular interaction
Abstract : Metal oxides are both corrosion products and useful materials with a wide range of applications. Two of the most used metals today are iron and copper. In this thesis, surface structures and molecular interaction with surfaces of iron oxides and copper oxides are studied using spectroscopy and microscopy methods. READ MORE

2. To metal, or not to metal : Diverse mechanisms of O2-activation and radical storage in the ferritin superfamily
Abstract : Proteins in the Ferritin-like superfamily are characterized by a four alpha-helical structural motif. These proteins are distributed across all three kingdoms of life and perform a wide range of functions. READ MORE

3. Development of metal hydride surface structures for high power NiMH batteries : Also extended cycle-life and lead to more effective recycling methods
Abstract : By combining alkaline etching of hydrogen storage alloys or their hydrides with a controlled oxidation, it was possible to improve reaction kinetics and accelerate activation of MH-electrodes. Both AB5 and AB2 alloys were studied where A is mixtures of rare earth elements for AB5 alloys and titanium and/or vanadium, zirconium for AB2 alloys; nickel contributes the major part of B.

4. Window Layer Structures for Chalcopyrite Thin-Film Solar Cells
Abstract : This thesis aims to contribute to the development of improved window layer structures for chalcopyrite thin-film solar cells, with an emphasis on the buffer layer, to assist future reductions of the levelized cost of energy. This is realized by exploring the potential of existing materials and deposition processes, as well as developing new buffer layer processes based on atomic layer deposition (ALD). READ MORE

5. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase
Abstract : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. READ MORE
