1. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications
Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER
2. Simulations of Silicon Carbide Chemical Vapor Deposition
Sammanfattning : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. LÄS MER
3. Transmission Electron Microscopy of Nanowires: Influence of Doping and Etching on Polytypism in InP
Sammanfattning : Semiconductor nanowires have many properties which makes them interesting for future electronic devices. The fact that they have very small diameters allow them to combine different III-V materials into heterostructures, and makes it possible to grow them on Si substrates which are the basis of nearly all current semiconductor technology.

4. Venturing Further into the Field of 2D Materials and their Laminated Parent Phases
Sammanfattning : The field of 2D materials is a relatively young and rapidly growing area within materials science, which is concerned with atomically thin states of matter. Because of their intrinsic 2D morphology, 2D materials have exceptionally high surface to weight or surface to volume ratio. LÄS MER
5. Design of carbide-based nanocomposite coatings
Sammanfattning : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. LÄS MER
