1. Depth Profiling of the Passive Layer on Stainless Steel using Photoelectron Spectroscopy
Sammanfattning : The physical properties of the protective passive films formed on the surface of stainless steels under electrochemical polarization in different electrolytes were studied. The structure of these films was analyzed as a function of depth using photoelectron spectroscopy (PES). LÄS MER
2. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films
Sammanfattning : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. LÄS MER
3. Contacts on Silicon Carbide by Use of Nickel and Tantalum ---Preparation and Characterisation
Sammanfattning : Silicon carbide (SiC) is one of the attractive semiconductors due to its good electrical, thermal and mechanical properties. It is a promising material for high temperature, high power and high frequency application. Reliable electrodes are always necessary to utilise SiC for electronic devices. LÄS MER
4. Development and Application of ToF-SIMS for Clinical and Microbiological Analysis
Sammanfattning : The aim of the work of this thesis was to further the implementation of timeof-flight secondary ion mass spectrometry (ToF-SIMS) in biological analysis and to generate new knowledge from the samples analysed. ToF-SIMS is a chemical analysis technique. LÄS MER
5. Non-Exhaust PM10 and Road Dust
Sammanfattning : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. LÄS MER
