  1. 1. Computer Simulations of Membrane–Sugar Interactions

    Författare :Jon Kapla; Arnold Maliniak; Alexander Lyubartsev; Ilpo Vattulainen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular simulations; Molecular dynamics; Lipid bilayers; Carbohydrates; Biological membranes; Trehalose; Glycolipids; Membrane—sugar interactions; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Carbohydrate molecules are essential parts of living cells. They are used as energy storage and signal substances, and they can be found incorporated in the cell membranes as attachments to glycoproteins and glycolipids, but also as free molecules. LÄS MER

  3. 2. Numerical Simulations of Plasmonic Nanostructures

    Författare :Joan Alegret; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoholes; DDA; Green s tensor; nanostructures; surface plasmons;

    Sammanfattning : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. LÄS MER

  4. 3. Alloy Plasmonics - Fundamentals and Applications

    Författare :Christopher Tiburski; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sensing; gold-palladium; nanothermometry; palladium-hydride; nanoalloys; photothermal; plasmonics; CO oxidation; heterogeneous catalysis; dielectric function;

    Sammanfattning : Alloys have for a long time been important in the development of our society; from the Bronze Age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, alloys have lately been proposed as a new paradigm in nanophotonics, to tailor optical properties of nanomaterials that find applications within telecommunication, sensing, or biotechnology.

  5. 4. Stellar kinematics in surveys and simulations

    Författare :Daniel Mikkola; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galactic dynamics; stellar dynamics; simulations; Gaia; Galactic dynamics; Stellar kinematics; Numerical simulations; Statistical methods; Solar neighborhood;

    Sammanfattning : We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. LÄS MER
