11. Reduction of heat transfer and heat load in internal combustion engines
Abstract : Thermal insulation of the combustion chamber in an engine has great potential to reduce fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. READ MORE

12. Modified oxygen and hydrogen transport in Zr-based oxides
Abstract : Most metals and alloys in the presence of oxygen and moisture will instantaneously react and form a thin (2-5 nm) surface oxide layer. For further reaction to occur, oxygen ions and/or metal cations often diffuse through the already formed oxide layer. READ MORE

13. Soft tissue integration to dental implants
Abstract : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. READ MORE

14. Deactivation of commercial three-way catalysts: Experimental and theoretical studies
Abstract : This PhD thesis is a summary of my work with thermal deactivated commercial three way catalysts (TWCs). An examination of catalytic properties, before and after accelerated aging was performed, such as light-off temperature, specific surface area (BET), noble metal dispersion and oxygen storage capacity was performed.

15. A Methodology to Control the Microstructure of Plasma Sprayed Coatings
Abstract : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.
