6. Thin water and ice films on minerals : a molecular level study
Abstract : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. READ MORE

7. Gas Adsorption and Permeation in MFI Zeolites and Membranes
Abstract : The single and multi component gas adsorption behavior on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. READ MORE

8. Study of H2/CO/CO2 adsorption on MFI zeolites for CO2 selective WGS membrane reactor concept
Abstract : The single-component adsorption behavior of CO, CO2 and multi-component adsorption of H2/CO2, CO/CO2, and H2/CO/CO2 on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. READ MORE

9. Electronic Structure of Transition Metal Complexes in Silicon
Abstract : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. READ MORE

10. Hydrogen in nominally anhydrous silicate minerals : Quantification methods, incorporation mechanisms and geological applications
Abstract : The aim of this thesis is to increase our knowledge and understanding of trace water concentrations in nominally anhydrous minerals (NAMs). Special focus is put on the de- and rehydration mechanisms of clinopyroxene crystals in volcanic systems, how these minerals can be used to investigate the volatile content of mantle rocks and melts on both Earth and other planetary bodies (e.
