21. From Facets to Flow: The Electrooxidation of Glycerol on Pd-based catalysts
Sammanfattning : Glycerol, a by-product of biodiesel refineries, has uses in industries such as cosmetics, food, and pharmaceuticals. However, its usage is small compared to the amount of glycerol produced from biodiesel production. LÄS MER
22. Exploring Biopolymer-Clay Nanocomposite Materials by Molecular Modelling
Sammanfattning : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. LÄS MER
23. Water film-mediated mineralogical transformations and photocatalytic reactions
Sammanfattning : Mineral particles capture water vapor in the atmosphere in the form of water films that are only few monolayers thick. Water films form nanoscale hydration environments that mediate a wide range of important reactions in nature and technology. LÄS MER
24. Artificial Photosynthesis: Molecular Catalysts for Water Oxidation
Sammanfattning : Artificial photosynthesis provides a promising solution to the future sustainable energy system. Water is the only suitably sufficient protons and electrons supplier by the reaction of water oxidation. However, this reaction is both kinetically and thermodynamically demanding, leading to a sluggish kinetics unless the introduction of a catalyst. LÄS MER
25. 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
