1. Adsorption of polyhydroxyl based surfactants
Sammanfattning : Adsorption on solid surfaces from solution is a fundamental property of a surfactant. It might even be the most important aspect of surfactant behavior, since it influences many applications, such as cleaning, detergency, dispersion, separation, flotation, and lubrication. LÄS MER
2. Atom Probe Tomography of Hydrogen and of Grain Boundaries in Corroded Zircaloy-2
Sammanfattning : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry for fuel cladding and structural components. The lifetime of the fuel assemblies in the reactors are largely dictated by the ability of the fuel cladding to withstand corrosion and mechanical damage. LÄS MER
3. Adsorption of nonionic amphiphiles to solid surfaces
Sammanfattning : In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. LÄS MER
4. Molecular overlayers on homogeneous and heterogeneous metal surfaces studied by core-level photoemission
Sammanfattning : The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. LÄS MER
5. Adsorption Properties of Triblock Copolymers at Solid Surfaces
Sammanfattning : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. LÄS MER
