  1. 16. Modelling and Simulation of Electro-catalysts for Green Energy : From Solvated Complexes to Solid-Liquid Interfaces

    Författare :Jose Luis Lima de Jesus Silva; Moyses Araujo; Mårten Ahlquist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Hydrogen Evolution Reaction; Hybrid Structures; Ruthenium Complexes; XPS; OER; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In this thesis, I have worked with solid-liquid interfaces, adsorbed molecules on the surface, and solvated complexes using Density Functional Theory (DFT) calculations to find possible signatures that could help design suitable energy materials. More specifically, I have explored hybrid electrocatalysts for hydrogen evolution reaction (HER), XPS fingerprints of gas-phase melamine (monomer, dimer, trimer, and hexagonal packed arrangement), hexagonally packed melamine adsorbed on the Au(111) surface, and high-valence Ruthenium complexes along a reaction pathway in aqueous solution through a joint theory-experiment approach.

  3. 17. Beyond Classical Ruthenium(II) Polypyridyl Complexes : Photosensitizers as Building Blocks For Linear Donor-Photosensitizer-Acceptor Assemblies

    Författare :Michael Jäger; Olof Johansson; Edwin Constable; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : This thesis describes ruthenium(II) polypyridyl-type complexes tailored for artificial photosynthesis. Inspired by Nature, the primary events in photosystem II are mimicked by donor-photosensitizer-acceptor (D-P-A) assemblies. LÄS MER

  4. 18. Kinetic Recognition of Nucleic Acids - Studies on the DNA Binding Selectivity of Threading Ruthenium Complexes

    Författare :Pär Nordell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intercalation; circular dicroism; ruthenium complexes; sequence selectivity; fluorescence; DNA; supercoiling; spectroscopy; kinetics;

    Sammanfattning : Despite the great progress in our understanding of DNA during the past half-century, there are many important aspects of its chemical and biological role yet to be explored. The principles by which it selectively interacts with other molecules have attracted much interest due to the relevance for fundamental cellular processes, as well as for the development of diagnostic probes and effective pharmaceutical agents.

  7. 20. Ruthenium-catalyzed C-H Functionalization of (Hetero)arenes

    Författare :Karthik Devaraj; Lukasz T. Pilarski; Victor A. Snieckus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; C-H activation; heterocycles; ruthenium; aryne precursor; silylation; gramine;

    Sammanfattning : This thesis concerned about the Ru-catalyzed C-H functionalizations on the synthesis of 2-arylindole unit, silylation of heteroarenes and preparation of aryne precursor.In the first project, we developed the Ru-catalyzed C2-H arylation of N-(2-pyrimidyl) indoles and pyrroles with nucleophilic arylboronic acids under oxidative conditions.
