1. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide
Abstract : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. READ MORE

2. Fundamental Investigations of Adsorption in SFC
Abstract : In supercritical fluid chromatography (SFC), the eluent is composed by carbon dioxide, often with additional components, in a condition between gas and liquid. This thesis aims to reach a deeper understanding of SFC by revealing the function of the additional eluent components through systematic adsorption studies. READ MORE

3. Surface and Bulk Reactivity of Iron Oxyhydroxides : A Molecular Perspective
Abstract : Iron oxyhydroxide (FeOOH) mineral plays an important role in a variety of atmospheric, terrestrial and technological settings. Molecular resolution of reactions involving these minerals is thereby required to develop a fundamental understanding of their contributions in processes taking place in the atmosphere, Earth’s upper crust as well as the hydrosphere.

4. Dissociative Adsorption of CO2 on Copper: The Role of Steps
Abstract : CO2 chemistry has received significant interest in recent time, due to the greenhouse effects of CO2 emissions and the resulting climate change. CO2 reduction reactions, such as methanol synthesis and reverse water-gas shift, is providing a route for recycling of CO2 and thus limiting the CO2 emissions. READ MORE

5. The Impact of Hydrocarbon and Carbon Oxide Impuritiesin the Hydrogen Feed of a PEM Fuel Cell
Abstract : The proton exchange membrane fuel cell generates electricity from hydrogen and oxygen (from air) through electrocatalytic reactions in an electrochemical cell. The Pt/C catalyst, commonly used in PEM fuel cells, is very sensitive to impurities that can interact with the active catalyst sites and limit fuel cell performance. READ MORE
