1. "De Andra" : afrikaner i svenska pedagogiska texter (1768-1965)
Sammanfattning : This study examines the way in which the image of the Sub-Saharan peoples is presented in the schools texts used in Sweden. The concept of ‘educational texts’ includes both used reading books and school texts for teaching geography. This study primarily concentrates on educational texts from 1768 up to 1965. LÄS MER
2. Surface force studies of association phenomena at solid-liquid interfaces
Sammanfattning : The main topics of this thesis, association phenomena inbulk and at solid-liquid interfaces in polar and non-polarmedia, were studied by a range of methods. Direct forcemeasurements employing the interferometric surface forceapparatus (SFA) was the chief technique. LÄS MER
3. Inter-firm relationships for sustainability : Incumbent firms and sustainability ventures
Sammanfattning : The magnitude of global environmental and social challenges puts business firms under constant scrutiny. To address such challenges, incumbent firms initiate and manage partnerships with external organizations. LÄS MER
4. Biolubricants and Biolubrication
Sammanfattning : The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants.

5. Grafted Molecular Layers for Control of Surface Properties
Sammanfattning : The goal of this thesis work was to develop responsive surface grafted brushlayers for control of surface properties and to gain insights in the molecular mechanisms that control these properties. Three types of grafted layers were investigated, as outlined below. LÄS MER
