1. Formation mechanism of anionic-surfactant-templated mesoporous silica (AMS)
Sammanfattning : This dissertation is focused on synthesis, characterization and formation mechanism of anionic-surfactant-templated mesoporous silica (AMS). Structural control mechanisms of AMS are investigated. LÄS MER
2. Isotopes as Mechanism Spies : Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects
Sammanfattning : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

3. Secondary Nucleation in Amyloid Formation
Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

4. Formation of mesostructured silica based on non-ionic interactions
Sammanfattning : Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. LÄS MER
5. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State
Sammanfattning : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mixandmeasurespectrophotometric technique and stoppedflow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.
