21. On the Adhesion Between Substrates Covered with Polyelectrolyte Multilayers
Abstract : This thesis examines the formation of Polyelectrolyte Multilayers (PEM) on cellulose fibres as a new way of influencing the fibre surface and the adhesion between wood fibres. The aim of the study was to enhance the fundamental understanding of the adsorption mechanisms behind the formation of Polyelectrolyte Multilayers on cellulose fibres; to study how the properties of the layers can be influenced and to show how the properties of the layers influence the adhesion between the fibres and the strength of paper sheets made from the PEM treated fibres.

22. Fractal analysis and surface characterization by atomic force microscopy and other methods
Abstract : This licentiate thesis focuses on fractal analysis of surfaces measured with atomic force microscopy (AFM) and other microscopic methods, and the correlation between fractal dimensions and tensile strength for pre-treated stainless-steel surfaces. The disadvantage is that the probe biases the image and the roughness measurement. READ MORE

23. Structure, Morphology, and Catalytic Properties of CuOx/CeO2 Model Catalysts
Abstract : Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. READ MORE

24. Surface Force and Friction : effects of adsorbed layers and surface topography
Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

25. Towards the Integration of Carbon nanostructures into CMOS technology
Abstract : Relentless efforts for miniaturization of traditional complementary metal oxide semiconductor (CMOS) devices have reached the limit where the device characteristics are governed by quantum phenomena which are difficult to control. This engendered a need for finding alternative new materials that can be engineered to fabricate devices that will possess at least the same or even better performance than existing CMOS devices.
