21. Interactions between non-polar surfaces in water: Fokus on talc, pitch and surface roughness effects
Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE

22. Structure and Phase Behavior of Protein Solutions
Abstract : The complexity of proteins is reflected in the structure of their fluids. This is seen from strongly inhomogeneous distributions about the single protein. Using molecular simulations of protein models, based on experimental structures, the present work probes the directional forces between proteins. READ MORE

23. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity
Abstract : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. READ MORE

24. Adsorption of Molecular Hydrogen on Cu, Pd and Ni Surfaces
Abstract : This thesis is devoted to spectroscopic studies of molecular hydrogen adsorbed on metal surfaces. Hydrogen is the simplest molecule available and is a very valuable model adsorbate. From a spectroscopic point of view there are also three easily accessible molecular isotopes, H2, HD and D2, with widely different masses. READ MORE

25. Following nanoparticle self-assembly in real-time : Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes
Abstract : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. READ MORE
