1. Phase Transformations in Solid Pharmaceutical Materials Studied by AFM, ESCA, DSC and SAXS
Sammanfattning : Mixing excipients is a common way to produce pharmaceutical materials with suitable properties for drug formulation. An understanding of the basic mechanisms involved in the formation and transformation of the structures of solid state mixtures is crucial if one is to be able to produce materials with the desired properties in a reliable way.

2. Passivation of Austenitic Stainless Steel
Sammanfattning : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). LÄS MER
3. On the interactions in cellulose systems : surface forces and adsorption
Sammanfattning : In this thesis the interactions in cellulose systems havebeen studied with emphasis on surface forces and adsorptionphenomenon. The study was limited to surfaces and polymers ofinterest for papermaking. LÄS MER
4. Silicone biomaterials obtained by plasma treatment and subsequent surface hydrosilylation
Sammanfattning : The need for safe and functional implants has led to anincreased demand for improved biomaterials. The performance invivo depends on the interaction between the biologicalsurrounding and the surface of the material. LÄS MER
