1. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water
Abstract : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. READ MORE

2. Chemical Processes at the Water-Manganite (γ-MnOOH) Interface
Abstract : The chemistry of mineral surfaces is of great importance in many different areas including natural processes occurring in oceans, rivers, lakes and soils. Manganese (hydr)oxides are one important group to these natural processes, and the thermodynamically most stable trivalent manganese (hydr)oxide, manganit (γ-MnOOH), is studied in this thesis.

3. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage
Abstract : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. READ MORE

4. Synthesis, Structure and Bonding in Polyiodides and Binary Metal Iodide-Iodine Systems
Abstract : Polyiodides and binary metal iodide-iodine compounds have been prepared and investigated by means of X-ray diffraction, EXAFS, far-IR, Raman, UV-vis and NMR spectroscopy and quantum chemical calculations. (Et3S)[AuI4].2I2 and (Me3S)[Cd2I6]1/2. READ MORE

5. CO oxidation over platinum-ceria catalysts -- Structural dynamics and reaction mechanisms
Abstract : Catalytic oxidation of carbon monoxide (CO) continues to be important due to its wide applicability in emission control, in-door air cleaning, fuel cell efficiency enhancement, chemical feedstocks purification etc. The transportation sector emits most of the CO emissions. READ MORE
