1. 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.

2. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications
Abstract : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. READ MORE

4. Ultrafast Magnetization Dynamics : Element-selective studies of magnetic alloys using ultra short XUV pulses
Abstract : In this thesis, I investigate the ultrafast magnetization dynamics in 3d ferromagnets and their alloys with ultrashort laser pulses. The high harmonics generation (HHG) setup provides extreme-ultraviolet photons with energies 35-72 eV, which is the energy range where 3d metals have their M2,3 absorption edges. READ MORE

5. Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants
Abstract : This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. READ MORE
