1. The effect of surface steps and oxides on the catalytic activity on model Pd and Rh catalysts
Abstract : A catalyst is a substance that can speed up the rate of a chemical reaction without itself being consumed. Catalysts are crucial for chemical production industries, where about 90% of all chemicals are produced using catalysts. READ MORE

2. Single-crystal Mo/V superlattices : growth, structure, and hydrogen uptake
Abstract : Fundamental studies concerning the growth, structural characterization and hydrogen uptake of single-crystal (00 l )-oriented Mo/V superlattices have been performed. The superlattices were grown by dual-target magnetron sputtering in pure Ar-atmosphere < 6·10-3 Torr on (001)-oriented MgO substrates. READ MORE

3. Using Light to Probe Surface Electrochemical Processes
Abstract : This thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. READ MORE

4. Experimental Studies of Charge Transport in Single Crystal Diamond Devices
Abstract : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. READ MORE

5. Adsorption of Molecules on Metal Surfaces Studied by High Resolution Core Level Photoemission
Abstract : Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. READ MORE
