  2. 21. First Principles Approach to the Hydrogen Pick-up during Oxidation of Zirconium Alloys by Water

    Author : Mikaela Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DFT; corrosion; zirconium alloys; hydrogen pick-up; electro-catalysis;

    Abstract : Zirconium alloys are widely used in nuclear power plants as cladding material to contain the fission fuel in the reactor cores. A limiting factor for fuel longevity is the corrosion property of the zirconium alloys. The main corrodent in the reactor core is water. READ MORE

  4. 22. Design, Synthesis and Characterization of Small Molecule Inhibitors and Small Molecule : Peptide Conjugates as Protein Actors

    Author : Jonas Nilsson; Lars Baltzer; Ingemar Kvarnström; Thomas Olsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synthetic receptor; Peptide inhibitor conjugate; Peptide protein surface interactions; General Lead Discovery Library; Combinatorial Chemistry; Solid Phase Chemistry; Targeted Library; Thrombin inhibitor; Fluorescence; Surface Plasmon Resonance; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes different aspects of protein interactions. Initially the function of peptides and their conjugates with small molecule inhibitors on the surface of Human Carbonic Anhydrase isoenzyme II (HCAII) is evaluated. READ MORE

  5. 23. Protein-water interactions studied by molecular dynamics simulations

    Author : Filip Persson; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Abstract : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. READ MORE

  6. 24. In-situ Study of the Growth, Composition and Morphology of III-V Semiconductor Nanowires

    Author : Robin Sjökvist; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Semiconductor; III-V; Transmission Electron Microscopy; In-situ; Environmental TEM; Crystal growth;

    Abstract : It is widely known that nanoparticle seeded growth of III-V semiconductor nanowires often occurs via the vapor-liquid-solid mechanism. However, conventional growth of nanowires is carried out in closed systems, where mostof the details and dynamics of the growth are impossible to follow. READ MORE

  7. 25. Beyond average crystal structures: understanding extended and local environments in proton-conducting Sc-substituted BaTiO3 perovskites

    Author : Nico Torino; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proton conducting oxide; IR; thermogravimetry; perovskite; neutron scattering; Raman; Reverse Monte Carlo; ordering; BaTiO3;

    Abstract : Proton conducting ceramics are very promising for applications concerned with energy sourcing with cleaner, safer, more abundant and cheaper alternatives to fossil fuels. These materials are still in development and advances in the field depend on a better understanding of the role of defects, their identification and location in the host framework, and the assessment of their short- and long-range dynamics and kinetics.
