21. Tribological evaluation of the contact between upper compression ring and cylinder liner with different surface coatings
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysikAbstract : The constant pursuit in the automotive industry to increase the engines performance, new solutions are always developed and tested to reduce the friction and increase the efficiency in the engine. One component that contributes to friction losses is the piston ring pack where the top compression stands for up to 40 %. READ MORE

22. Variability of GHG emissions from emergent aquatic macrophytes in mixed boreal and Equisetum dominated communities
University essay from Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Filosofiska fakultetenAbstract : Plants (macrophytes) growing in lake and wetland sediments are known mediators of greenhouse gases (GHG), specifically methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). Current studies have emphasized the potential risk of underestimation regarding emissions of plant-mediated GHGs from terrestrial systems including lakes, streams and other freshwater bodies.

24. Investigation of the dielectric breakdown strength of polymer nanocomposites
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : The aim of this thesis is to investigate the possibility of enhancing the dielectric breakdown strength (DBS) of low density polyethylene (LDPE) with addition of voltage stabilizing additives. In the first part of the thesis, the influence of various process parameters on the alternating current DBS of pure LDPE and LDPE containing either 3 or 30 wt% magnesium oxide nanoparticles was investigated.

25. Iron Oxide Thin Film Growth On Ag(100)
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikAbstract : This thesis presents a study of iron oxide thin films, grown on a silver metal substrate, with the goal of characterizing the structures that form during growth of the first atomic layers. Such ultra-thin iron oxides are interesting model materials for fundamental surface chemistry and catalysis studies. READ MORE
