11. Deactivation of emission control catalysts for heavy-duty vehicles : Impact of biofuel and lube oil-derived contaminants
Abstract : Catalytic emission control is used to reduce the negative impact of pollutants from diesel exhausts on our health and on the environment. For a heavy-duty truck, such a system consists of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), a selective catalytic reduction (SCR) catalyst, and an ammonia slip catalyst (ASC).

12. Numerical modelling of biomass thermochemical conversion and potassium release
Abstract : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. READ MORE

14. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles
Abstract : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.

15. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon
Abstract : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. READ MORE
