1. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process
Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

2. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets
Abstract : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. READ MORE

3. Theoretical Studies on CO2 Reduction Electrocatalysts
Abstract : The atmospheric CO2 concentration has increased by more than 20% since 1980s and has now reached the highest level than at any point in the past 800 000 years. Electrochemical CO2 reductions are receiving particular in- terest as the apparatus are relatively easy to maintain and cheap to operate. READ MORE

4. Enzymatic Reduction of Ketones
Abstract : Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. READ MORE

5. Modeling and Model Reduction by Analytic Interpolation and Optimization
Abstract : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. READ MORE
