26. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams
Sammanfattning : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.

27. A study of an autogenous slag for steel production with consideration of possible vanadium extraction
Sammanfattning : The thesis discusses the use of the autogenous slag that forms from the residual oxides present in hydrogen reduced iron (H-DRI) pellets during melting. The studies are motivated by a better understanding of how H-DRI affect the steelmaking operations. LÄS MER
28. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties
Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER
29. Morphology Characterization of Foam Bitumen and Modeling for Low Temperature Asphalt Concrete
Sammanfattning : Development of new asphalt technologies to reduce both energy consumption and CO2 production has attracted great interest in recent years. The use of foam bitumen, as one of them, is attractive due to the low investment and production cost. LÄS MER
30. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers
Sammanfattning : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. LÄS MER
