21. Blood protein coated model biomaterials : preparation, and cell and tissue response
Sammanfattning : Solid biomaterials are widely used in bone and in soft tissue applications. Problems may then arise due to a prolonged inflammation in the proximity of the implant, resulting in the formation of a fibrous capsule and a low vascularisation near the interface. LÄS MER
22. Hydrodynamic lubrication of rough surfaces
Sammanfattning : Interacting surfaces are frequently found in mechanical systems and components. A lubricant is often added between the surfaces to separate them from mechanical contact in order to increase life and performance of the contacting surfaces. In this work various aspects of hydrodynamic lubrication are investigated theoretically. LÄS MER
23. Design of Cellulose-based Materials by Supramolecular Assemblies
Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

24. Emissions of organic compounds from technosphere articles : Measurements and modeling of mass transfer from consumer goods and building materials to air and water
Sammanfattning : This thesis describes the development of a generic model for predicting the emissions of organic compounds from materials used in the manufacture of various goods and products. Many products contain organic substances that are not bound to the matrix formed by their constituent materials and are thus able to dissociate from the material and become transferred into the surrounding environment.

25. The Friction between Paper Surfaces
Sammanfattning : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.
