11. Synchrotron Radiation, Adsorption Isotherms and the Large Hadron Collider Vacuum System
Sammanfattning : In circular particle accelerators and storage rings with relativistic beams of particles, e.g. electrons or protons, the vacuum performance of the accelerator is determined by the outgassing from the walls of the beam vacuum chamber. LÄS MER
12. Sorption of Cs, Ba, Co, and Eu onto biotite: experiments and modelling
Sammanfattning : The sorption of 134Cs, 133Ba, 60Co and 152Eu, all at about [~10-8 M] onto biotite mineral was studied using the batch method with S: L = 1:50 at three different ionic strengths (0.001, 0.01 and 0.1M NaClO4) and five different pH (5,6,7,8,9) at 25°C for up to two months in an inert atmosphere glovebox.

13. Adsorption of Molecules on Metal Surfaces Studied by High Resolution Core Level Photoemission
Sammanfattning : 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. LÄS MER
14. Interaction of CO and methane with platinum, Low-temperature oxidation and sensor response mechanisms
Sammanfattning : The aim of this thesis project was to increase the understanding of the mechanisms for low-temperature oxidation of carbon monoxide and methane over supported platinum catalysts. In situ spectroscopic methods together with mass spectrometry were used to study the catalysts during both steady state and transient conditions. LÄS MER
