21. Development of low-cost ionic liquids based technology for CO2 separation
Abstract : CO2 separation plays an important role to mitigate the CO2 emissions due to burning of fossil fuels, and it is also of importance in biofuel production (e.g. biogas upgrading and bio-syngas purification and conditioning). The solvent-based absorption is the state-of-art technology for CO2 separation, where various solvents, e. READ MORE

22. Novel Materials for Fuel Cells and Batteries Light Scattering Studies of the Structure and Dynamics of Polymer Electrolytes
Abstract : The development of new materials and technologies for electrochemical energy conversion and storage, such as fuel cells and batteries, is important for a future more efficient use of energy. Polymer electrolytes are key components in polymer electrolyte fuel cells and lithium-based batteries. READ MORE

23. Mechanism Studies of Catalytic RNA, and RNA and DNA Model Compounds
Abstract : This thesis describes mechanism studies of transesterifications of phosphate esters. The aim of the studies concerns two fields. First, the catalytic mechanism that group I introns use in self-splicing. The focus was on metal ion coordinating groups at the catalytic site. READ MORE

24. Selective Catalytic Reduction of NOx with NH3 - Kinetic Modeling and Experimental Studies using Zeolite Based Catalysts
Abstract : Emissions from the combustion of fossil fuel contain several pollutants which can be converted over a catalyst to less harmful products. An efficient way to reduce nitrogen oxides in a lean environment is to apply selective catalytic reduction of these oxides with ammonia (NH3 SCR). READ MORE

25. Morphology of Polymers - Development of Electron Microscopy Methods
Abstract : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. READ MORE
