11. Physico-Chemical Investigations of, and Characterization of Model Membranes for, Lipid-Peptide Interactions
Sammanfattning : The main focus of this thesis is on the effects caused by α-helical peptides on liposome structure, the impact of cholesterol on the peptide-membrane interactions, and the effect of aggregate curvature on the peptide affinity. Results of the studies show that the membrane destabilizing effect of the cationic α-helical peptide melittin is modulated by cholesterol. LÄS MER
12. Simulation of deformable objects transported in fluid flow
Sammanfattning : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.

13. Elastic properties of suspended graphene
Sammanfattning : This thesis concerns describing the mechanical properties of the two dimensional material graphene by continuum elasticity theory. In particular, Nano ElectroMechanical Systems (NEMS) where part of the graphene sheet is made suspended, are considered. LÄS MER
14. Physico-Chemical Investigations of Bilayer Discs and Related Lipid Structures Formed in Liposomal Systems Intended for Triggered Release
Sammanfattning : This thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated. LÄS MER
15. Molecular organization and in situ assembly of the human skin barrier
Sammanfattning : A deficient skin barrier function is a characteristic feature of skin diseases such as eczema, psoriasis and the ichtyoses. A malformation of the lipid matrix might be a major factor in barrier deficient skin disease. LÄS MER
