1. Metal film growth on weakly-interacting substrates : Multiscale modeling
Abstract : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. READ MORE

2. Metal-exchanged zeolites for NH3-SCR applications - Activity and Deactivation studies
Abstract : Emissions of nitrogen oxides (NOX) formed during the burning process in internal combustion engines is a major contributor to global air pollutions. One effective way to reduce NOX in lean environments, i.e. oxygen excess is selective catalytic reduction with ammonia (NH3-SCR). READ MORE

3. Quantum aspects of hydrogen in metals and oxides from density-functional calculations
Abstract : Atomic hydrogen dissolved in a solid or adsorbed on a solid surfacedisplays many remarkable features, and is a subject ofgreat technological interest.An increased understanding of hydrogen/solid systems can supportthe development of areas as diverse asproton exchange membranes for fuel cells,heterogeneous catalysis, and growth of semiconductor devices.

4. Studies on preparation and properties of nanophase metal oxides
Abstract : This thesis is about science on an atomic scale - aninterdisciplinary approach to nanoparticles. Studies of thepreparation of nanoparticles using both physical and chemicalmethods are presented. Understanding and controlling factorsfor particle growth during synthesis are the keys to successfulfabrication of materials with tailored properties. READ MORE

5. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals
Abstract : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). READ MORE
