1. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth
University essay fromAbstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE

2. Implications of different sensor resolutions and contrast settings in a roll-to-roll process, considering the speed of the process vs identifying defects, for manufacturing green batteries : A study on the effect of light conditions on thedetection of defects in cathode foil in batteries
University essay from KTH/MekatronikAbstract : This Master’s thesis work is about the conditions that can affect the identification of defects in lithium-ion batteries. In lithium batteries, there are cathode and anode, which are separated with electrically insulative but ionically conductive electrolytes and separators. READ MORE

4. Improved interconnect materials for next-generation Solid Oxide Fuel Cells
University essay from KTH/MaterialvetenskapAbstract : Solid Oxide Fuel Cells (SOFC) are attractive candidates in the search for cleaner and energy efficient production due to their numerous advantages such as fuel flexibility, modularity and exceptional efficiencies when combined heat and power is harnessed. A key element in its design are the interconnects which are mainly manufactured from custom ferritic stainless steels to carry the electricity between two adjacent cells. READ MORE
