1. Vanadate and Peroxovanadate Complexes of Biomedical Relevance : A speciation approach with focus on diabetes
Abstract : Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain.

2. Open-framework Structures Built by Inorganic Clusters : Synthesis and Characterization
Abstract : Novel open-framework germanates and vanadoborates, which are constructed from typical types of clusters, have been synthesized based on different strategies. The crystal structures are solved by using single crystal X-ray diffraction (SXRD) technique or by combined techniques. READ MORE

3. Reactions of Model and Anticancer Active Platinum(IV/II) Complexes - A Kinetic and Mechanistic Study
Abstract : In this thesis reductions of model and anticancer active Pt(IV) complexes with thiols and ascorbic acid and substitution reactions of cisplatin and model Pt(II) complexes with S-donor nucleophiles (rescue agents) have been investigated using stopped-flow and UV/VIS spectrophotometry. Glutathione (GSH) reduction of the anticancer active Pt(IV) compounds t- and c-[PtCl4(cha)(NH3)] (cha = cyclohexylamine), t-[PtCl4(thiazole)(NH3)] and c-[PtCl4(NH3)2] at 25 oC was observed to be very fast.

4. Interactions of Anticancer Active Platinum(II) Complexes with DNA
Abstract : The kinetics and mechanism for interactions of the anticancer active platinum(II) complexes cis-[PtCl2(NH3)2)], cis-[PtCl2(NH3)(c-C6H11NH2)], and trans-[PtCl2-(NH3)(quinoline)] with DNA have been studied using a combination of HPLC, circular dichroism (CD), UV/vis spectroscopy, and differential scanning calorimetry (DSC). Reactions of the monoaqua forms (charge = +1) of these complexes with single-stranded DNA oligonucleotides, typically between 13-17 bases long, were found to depend on i) the composition of the reaction medium, ii) the exact nature and location of the platination target, and iii) on the DNA structure.

5. Chemical Processes at the Water-Manganite (γ-MnOOH) Interface
Abstract : The chemistry of mineral surfaces is of great importance in many different areas including natural processes occurring in oceans, rivers, lakes and soils. Manganese (hydr)oxides are one important group to these natural processes, and the thermodynamically most stable trivalent manganese (hydr)oxide, manganit (γ-MnOOH), is studied in this thesis.
