1. Wettability of modified wood
Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER
2. Synchrotron X-ray Scattering and Monte Carlo Simulations of Structure and Forces in Silicate Nanoplatelet Dispersions
Sammanfattning : Clays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. LÄS MER
3. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications
Sammanfattning : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. LÄS MER
4. Alloy element redistribution during sintering of powder metallurgy steels
Sammanfattning : Homogenization of alloying elements is desired during sintering of powder metallurgy components. The redistribution processes such as penetration of liquid phase into the interparticle/grain boundaries of solid particles and subsequent solid-state diffusion of alloy element(s) in the base powder, are important for the effective homogenization of alloy element(s) during liquid phase sintering of the mixed powders.

5. Ultrastructure of the Primary Cell Wall of Softwood Fibres Studied using Dynamic FT-IR Spectroscopy
Sammanfattning : The primary cell wall is a complex multipolymer system whose composite structure has been mostly determined from chemical and biochemical studies. Although the primary cell wall serves a central role, with regard to the connective properties of fibres, knowledge about the interactions among the polymers, when it comes to the mechanical properties, is very limited.
