1. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. READ MORE

2. Lead Concentrations in Indoor Dust : Differences Between Indoor Shooting Ranges and Assumed Non-Lead Contaminated Sites
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : A projectile which missed its target and falls into the bullet trap at the end of the shooting range might not be viewed as dangerous. Yet, hazardous fumes and fine metal fragments from the bullet might contaminate the users of the shooting range. READ MORE

3. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

4. Synthesis and Characterization of Multi-component Metal Oxides based on Ru-Co-Mo as Oxygen Evolving Electrocatalysts
University essay from Umeå universitet/Institutionen för fysikAbstract : Finding materials based on non-rare earth metals is vital for the global transition to a more sustainable economy. Discovering useful properties in common metal oxides is a promising avenue for new materials. READ MORE

5. Biocatalysis in Pickering emulsions
University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)Abstract : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. READ MORE
