1. The life and death of perovskites : Interfacial function and degradation of lead halide perovskites studied by photoelectron spectroscopy
Sammanfattning : Lead halide perovskite solar cells are a promising new technology which could soon see widespread commercial application but is partly held back by poor long-term stability. In this thesis, photoelectron spectroscopy (PES) is used to study the dynamical processes at the surface or interfaces of lead halide perovskite materials. LÄS MER
2. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems
Sammanfattning : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. LÄS MER
3. Modification of Surface Properties Through Polymer Adsorption. Kinetics, Interaction, Degradation and Stability
Sammanfattning : The interfacial behaviour of polymers in relation to surface modification and polymer degradation was studied. In the first part the interfacial behaviour of amphiphilic poly(ethylene oxide)–poly(D,L-lactide) (EmLn) diblock copolymers at hydrophilic and hydrophobic substrates from aquous solution was studied.

4. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Sammanfattning : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. LÄS MER
5. Non-aqueous Electrolytes and Interfacial Chemistry in Lithium-ion Batteries
Sammanfattning : Lithium-ion battery (LIB) technology is currently the most promising candidate for power sources in applications such as portable electronics and electric vehicles. In today's state-of-the-art LIBs, non-aqueous electrolytes are the most widely used family of electrolytes. LÄS MER
