37. Oxidation of some Late Transition Metal Surfaces: Structural Studies from UHV to Atmospheric Pressure
Abstract : The oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scanning tunneling microscopy, as well as density functional theory calculations.

38. Characterization of Surfaces Relevant to Nanotechnology
Abstract : In this thesis investigations of the structure and dynamics of semiconductor surfaces relevant for the synthesis of nanostructures are presented. The studies were performed using Scanning Tunneling Microscopy (STM), Low Energy Electron Diffraction (LEED), and Spectroscopic PhotoEmission and Low Energy Electron Microcopy (SPELEEM). READ MORE

39. Studies of Catalytic Low-Temperature CO Oxidation over Cobalt Oxide and Related Transition Metal Oxides
Abstract : The catalytic oxidation of carbon monoxide at low temperatures is important in many applications. The use of a low temperature active catalyst may lower the emissions during the cold-start of a car, and volatile organic compounds in exhaust gases from stationary sources might be treated without the need of preheating the gas.

40. Development of New Bacteria-Reducing Surfaces
Abstract : In recent years, antibacterial surfaces have been a subject of increased interest. Especiallyinteresting are non-leaching, contact-active surfaces that physically disrupts the bacterialcell using immobilised cationic polymers. Thus the risks of bacterial resistance and discharge of hazardous biocides is minimised. READ MORE
