Tailored low consistency refining for targeted fiber properties
(Åbo Akademi, 2020)The main aim of the study has been to analyze the impact of refining on the physical and optical properties of paper sheets with respect to change in three refining parameters. The three parameters that have been changed ... -
Techno-economic analysis of a reversible solid oxide cell and hydrogen gas storage system
(Åbo Akademi, 2019)As the share of intermitted renewable energy increases, there will be a growing demand of grid balancing energy storage solutions. A new type of energy storage is using hydrogen gas as an energy carrier and reversible solid ... -
The effects of temperature treatments on the structure of an injectable depot material consisting of silica microparticles and a silica hydrogel
(2022)During transportation of injectable depot materials, temperature variations might occur as they are shipped globally in different climates. A systematic approach to study the effects of temperature variations was therefore ... -
The fate of Sn, Pb, Cu, and Ni from e-waste in secondary copper smelting
(2023)Electronic waste (e-waste) is waste generated from end-of-life electrical and electronic equipment. E-waste is the fastest growing type of solid waste stream. This has become a major environmental concern. Fortunately, the ... -
The potential of lignin as a maritime biofuel
(2021)In the 1940s, efforts towards lignin valorisation were triggered by high oil prices, but today, the motives are much more varied. The movement towards a greener future to combat climate change and the expected introduction ... -
The Potential Use of LNG in SSAB Raahe Steelworks
(2020)Steel has been produced for thousands of years, but its extensive, industrial use began during the industrialization, with the introduction of more efficient production methods, such as the blast furnace. The global ... -
The short sea shipowner taking on new waves of innovation

Thermal degradation and stabilization of HVDC power cable insulation materials based on polypropylene
(2022)In this work, a series of antioxidant formulations’ effectiveness for propylene copolymers intended to be used as insulation materials for HVDC cables has been eval-uated by subjecting the polymer samples to forced-air ... -
Thin-layer composite reference electrodes
(Åbo Akademi, 2020)In this thesis work the performance and feasibility of a thin layer polymer:salt composite reference electrode was assessed, in an attempt to further miniaturize the all solid-state reference electrode previously made. The ... -
Tuning strategies for control of integrating systems with model predictive control
(2022)The objective of this thesis was to verify the suitability of Valmet’s own MPC solution, DNAMPC2, when applied to a common system encountered in process industry and biofuels processing. An extensive literature study was ... -
Utilization of waste heat sources to lower energy consumption at a paper mill
(2022)The environmental impact has become an important aspect to consider for companies. Energy efficiency is a significant part of the environmental impact that is continuously improved. New solutions are found to increase the ... -
UV-initierad fotopolymerisation vid tillverkning av slipmaterial
(Åbo Akademi, 2020)Ett konventionellt, flexibelt slipmaterial består i sin enklaste form av ett substrat, till exempel papper, ett limlager som fäster slipkornen vid bottenmaterialet samt ytterligare ett limlager för att vidare förankra ... -
Water resistant electrospun nanofibers composed of nanocellulose and conducting polymer
(Åbo Akademi, 2019)Nanofibers of novel polymer compositions containing cellulose nanofibrils and the conducting polymer poly(3,4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) were prepared via electrospinning and ...
