1. Atomic Scale Modelling in Photoelectrocatalysis : Towards the Development of Efficient Materials for Solar Fuel Production
Abstract : Using sunlight to produce valuable chemicals has been pointed out as an interesting alternative to deal with the well-known environmental problem related to the use of fossil fuels for energy generation. Thus, it is crucial for this field the development of novel photocatalysts that could drive the uphill reactions with high efficiency while presenting low price and toxicity. READ MORE

2. A biophysical study of nucleic acid interactions with analogues and drugs
Abstract : work presented in this thesis concerns studies on the physicochemical nature of interactions between nucleic acids and small ligands. The outcome of such studies can yield insights at a molecular level into the physiological mechanisms of action of biologically active nucleic-acid binding molecules. READ MORE

3. DNA Binding of Metal Complexes. A Spectroscopic Study of Trigonal Ru(II)phenanthroline Complexes and Uranyl(VI) Ion with Respect to Specific Interactions with DNA
Abstract : The interaction of metal complexes with nucleic acids has attracted attention owing to their potentials as optical probes, probes of chirality, and for use as artificial restriction enzymes. To understand the underlying mechanisms in these contexts we studied the binding to DNA of the enantiomers of two chiral ruthenium(II) metal complexes ([Ru(phen)3]2+ and [Ru(phen)2]2+DPPZ) phen=1,10-phenanthroline, DPPZ=dipyrido[3,2-a:2',3'-c]phenazine, and of the linear uranium(VI) complex, uranyl ([UO2]2+), using linear dichroism, circular dichroism and luminescence, as well as nuclear magnetic resonance spectroscopy.

4. Computational Studies of Nitrogenase
Abstract : AbstractNitrogenase is the only enzyme that can convert the inert nitrogen molecule to ammonia, so that it can be used for biomass production and in biosynthetic pathways. It contains a complicated acitve site, composed of eight metal ions, nine sulfur ions and one carbide ion (the FeMo cluster). READ MORE

5. Design, Synthesis and Thermodynamic Studies of Galectin Ligands
Abstract : The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. READ MORE
