1. X-ray spectroscopy on diatomic and cationic molecules
Abstract : X-ray spectroscopy have been used to study the electronic structure of diatomic and cationic molecules. X-ray absorption spectra of the molecular cations N2+, O2+, and CO+ have been measured. READ MORE

2. Self-assembly in Melts of Block copolymer-based Systems Featuring Supramolecular Interactions
Abstract : The subject of this thesis is experimental investigation of self-assembly in solvent-free (ionic) macromolecular systems that contain block copolymer chains as the basic constituent component in combination with low molecular weight amphiphiles. In particular, especial attention is paid to study thoroughly a new class of block copolymer-based ionic supramolecules, named as Linear-b-AmphComb, that feature novel hierarchical self-assembly characteristics.

3. Equilibrium and Kinetic Studies of the Binding of DNA to Cationic Liposomes
Abstract : The objective of this work was to study the formation of DNA-cationic vesicle complexes (lipoplexes). These complexes are interesting not only from a fundamental point of view but also as promising candidates for gene therapy. The approach taken was to study first the cationic vesicles by themselves.

4. Cationic Interactions with Nucleic Acids With Focus on Anticancer Active Platinum(II) Complexes
Abstract : It is well documented that the antitumour activity of the Pt(II)-complex cisplatin, and similar anticancer active complexes, is a result of metalation of DNA, and thereby inhibition of cell proliferation. Since nucleic acids are polyanions at physiological pH, the rate of adduct formation with positively charged complex, as the hydrolyzed Pt(II) complexes studied in this work, is influenced by the ionic environment surrounding the polymer.

5. Immunochemical characterisation of Brucella LPS and its relation to virulence
Abstract : Members of the genus Brucella are facultative intracellular pathogens which infect and produce disease in a wide variety of mammals. Although some factors have been implicated in the virulence of Brucella, the virulence mechanisms of this intracellular pathogen are not known. READ MORE
