1. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?
Abstract : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. READ MORE

2. Modeling DNA Damage
Abstract : In this thesis methods of computational chemistry have been used to examine DNA damaging processes initiated by ionizing radiation, free radicals, or Low-Energy Electrons (LEE). The computational chemistry method based on quantum mechanics that has been mainly used here is the Density Functional Theory (DFT). READ MORE

3. Catabolism of Pyrimidines in Yeast
Abstract : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. READ MORE

4. RNA-protein interactions in the bacteriophage MS2
Abstract : The bacteriophage MS2 coat protein interacts specifically with a 19 nucleotide long hairpin formed within the viral RNA genome. In the current work the structural details of this interaction have been examined using X-ray crystallography of complexes where the RNA hairpin sequence has been varied. READ MORE

5. Design of pyrimidine-based photoresponsive surfaces and light induced wettability control
Abstract : For photochromic molecules, the ability to switch reversibly between two states is controlled largely by structural effects. The photodimerization of 5-methyluracil, commonly known as thymine, a member of the pyrimidine family and one of the DNA bases, is a particularly important reaction in photobiology, one which occurs when the molecule is subjected to UV irradiation.
