2. LIGNIN DEPOLYMERISATION IN NEAR- CRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS: EFFECT OF CO-SOLVENT AND pH
Abstract : Lignin is a complex three-dimensional amorphous polymer, which, along with cellulose and hemicellulose, forms a main component of biomass. Its main role is in giving strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. READ MORE

3. Experimental investigation of hydrocarbon formation and transformation under Earth´s upper mantle conditions
Abstract : The theory of the abyssal abiotic petroleum origin considers oil and natural gas to begenerated in the Earth’s upper mantle. Hydrocarbons migrate further through the deep faults into the Earth’s crust, where they can form oil and gas deposits in any kind of rock in any kind of structural position. READ MORE

4. The Heterocysts of Nostoc punctiforme : From Proteomics to Energy Transfer
Abstract : The aim of this thesis is to provide a thorough characterization of the photosynthetic machinery from the heterocysts of Nostoc punctiforme strain ATCC 29133. In this thesis I describe the protocols I have optimized for the isolation of thylakoids from vegetative cells, the purification of heterocysts and the isolation of thylakoids from the purified heterocysts.

5. Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis
Abstract : The work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. READ MORE
