1. Global stability analysis of complex fluids
Sammanfattning : The main focus of this work is on the non-Newtonian effects on the inertial instabilities in shear flows. Both inelastic (Carreau) and elastic models (Oldroyd-B and FENE-P) have been employed to examine the main features of the non-Newtonian fluids; shear-thinning, shear-thickening and elasticity.

2. Interaction Studies in Complex Fluids with Optical Biosensors
Sammanfattning : In this thesis interactions in complex fluids, such as serum and meat juice, were analysed with optical biosensor techniques.Panels of lectins immobilised on gold surfaces were used for investigation of differences in protein glycosylation pattern in sera and meat juices between various species.

3. Composite Cryogels: Stationary Phase for Separation of Complex Media
Sammanfattning : Demands for efficient, economical and fast separation and purification methods for various target molecules have led to the development of new techniques and materials for bioseparation processes. Separation can be carried out in both batch and chromatographic modes. LÄS MER
4. Opportunities and challenges of surface scattering at next generation neutron sources
Sammanfattning : Complex fluids and soft matter are ubiquitously found in the world and all contacts in life are made over surfaces. To describe the mechanical behavior of such substances, rheological methods are used. Flow instabilities are a big challenge in rheology since they will be reflected in the macroscopic variables probed, like e. g. LÄS MER
5. NMR studies of complex fluids and solids formed by surfactants
Sammanfattning : NMR methods have been designed and employed in studying ofcomplex liquids and solids formed by surfactants. PGSE NMRexperiments are easily biased by convection; this artifact canbe avoided by changing the sample holder and by usingconvection-compensated pulse sequences. LÄS MER
