2. 1. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation

   Author : Lele Duan; Licheng Sun; Matthias Beller; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; water oxidation; ruthenium; electrochemistry; DFT calculation; photoelectrochemistry; negatively charged ligand; catalyst;

   Abstract : This thesis concerns the development and study of Ru-based water oxidation catalysts (WOCs) which are the essential components for solar energy conversion to fuels. The first chapter gives a general introduction about the field of homogenous water oxidation catalysis, including the catalytic mechanisms and the catalytic activities of some selected WOCs as well as the concerns of catalyst design.

4. 2. Protein Interactions: Electrostatics and Ligand Binding

   Author : Ingemar André; Biofysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; secondary structure formation; protein GB1; pKa values; pH stability; NMR; electrostatic interactions; M proteins; calbindin D9k; calcium binding; cooperativity; calmodulin; calbindin D28k;

   Abstract : This thesis deals with Ca2+ binding to proteins, electrostatic interactions in and between proteins as well as inter- and intramolecular interactions. A computer program was developed to determine Ca2+ binding constants from experimental titration data of proteins. READ MORE

5. 3. Synthesis of donor–acceptor–donor thiophene based ligands that can be utilized for optical assignment of pathological targets

   Author : Linda Lantz; Peter Nilsson; Peter Konradsson; Jerker Mårtensson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Thiophene based ligands represent a class of molecular reporters proven superior in discerning pathological targets involved in neurodegenerative diseases, as well as bacterial infection. By fluorometric detection that depends on the milieu surrounding the ligand these biological processes can be studied with fluorescence spectroscopy and hyper-spectral confocal microscopy. READ MORE

6. 4. Photoinduced Electron Transfer in Luminescent Lanthanide Complexes

   Author : Daniel Kovacs; Eszter Borbas; Stephen Faulkner; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lanthanide; Luminescence; Photoinduced electron transfer; Kemi; Chemistry;

   Abstract : Luminescence from the trivalent lanthanides is used for detection in biological systems. Lanthanide luminescence is usually sensitized by a light-harvesting organic chromophore (’antenna’). An ideal emitter has an antenna that efficiently transfers energy to the lanthanide, and a ligand that shields the metal from quenching solvent molecules. READ MORE

7. 5. Protein-protein interactions in model systems : design, control of catalytic activity and biosensor applications

   Author : Johan Rydberg; Lars Baltzer; Joel Schneider; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein interactions; design; catalysis; biosensors; hybride materials; nanoparticles; Kemi; Chemistry; Kemi;

   Abstract : This thesis describes the design of polypeptides, unordered in the monomeric state but capable of folding into helix-loop-helix motifs and dimerise to form four-helix bundles. The goal of the design was to encode them with the capacity to form dimers highly selectively and the ability to carry out molecular functions in the folded state but not in the unordered state, and thus to establish a molecular link between recognition and function.
