6. Online characterization of wood pulp : foundations for a photoacoustic sensing technique
Sammanfattning : Today, there is an increasing demand in the paper industry for better utilisation of the raw material and improved energy efficiency. Also, the increasing use of recycled paper in the manufacturing process leads to a situation where the knowledge of pulp properties needs to be improved and controlled. LÄS MER
7. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration
Sammanfattning : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.

8. Fundamental Characterization and Technical Aspects of a Chelating Surfactant
Sammanfattning : The purpose of this study was to investigate the fundamental characteristics of a chelating surfactant in terms of solution behaviour, chelation of divalent metal ions, and interaction in mixtures with different foaming agents and divalent metal ion, as well as examining its prospects in some practical applications. Chelating surfactants are functional molecules, with both surface active and chelating properties, which are water soluble and therefore suitable for chelation in many aqueous environments. LÄS MER
9. Green Liquor Dregs in Sealing Layers to Prevent the Formation of Acid Mine drainage : From characterization to implementation
Sammanfattning : One of the mining industry’s main concerns is the management of waste rock and tailings generated by sulfide ore extraction. Upon exposure to atmospheric oxygen, iron sulfides oxidize producing acidity. LÄS MER
10. Recycling of cotton textiles: Characterization, pretreatment, and purification
Sammanfattning : In many parts of the world, there are well-established systems for material recycling of metal, glass, and paper. However, no large-scale chemical recycling of textiles currently exists. LÄS MER
