1. Modification of Surface Properties Through Polymer Adsorption. Kinetics, Interaction, Degradation and Stability
Abstract : 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.

2. Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces
Abstract : Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport.

3. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications
Abstract : This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. READ MORE

4. Polyelectrolytes : Bottle-Brush Architectures and Association with Surfactants
Abstract : This thesis has the dual purpose of raising awareness of the importance of the mixing protocol on the end products of polyelectrolyte-oppositely charged surfactant systems, and to contribute to a better understanding of the properties of bottle-brush polyelectrolytes when adsorbed onto interfaces. In the first part of this thesis work, the effects of the mixing protocol and the mixing procedure on formed polyelectrolyte-oppositely charged surfactant aggregates were investigated. READ MORE

5. Properties and fungal decomposition of iron oxide-associated organic matter
Abstract : Soil organic matter (SOM) stores the largest quantity of C in terrestrial ecosystems. Most SOM can be decomposed by microorganisms and released as CO2 into the atmosphere. The remaining fraction of SOM can be resistant against microbial decomposition over centuries to millennia. READ MORE
