  1. 16. Boundaries of displacement : Belonging and Return among Forcibly Displaced Young Georgians from Abkhazia

    Författare :Minna Lundgren; Roine Johansson; Anna Olofsson; Barzoo Eliassi; Tone Bringa; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Georgia; Abkhazia; Caucasus; IDP; internal displacement; return; forced displacement; youth; border; riskscapes; uncertainty;

    Sammanfattning : This dissertation explores the implications of borders and boundaries for how forcibly displaced young Georgians from Abkhazia understand issues of belonging and return. My theoretical framework draws from theories on home and belonging as well as theories on border and boundary making, and locates them in geographies of uncertainty – or riskscapes – areas characterized by conflict and/or inequality.

  3. 17. Ground and Excited State Aromaticity : Design Tools for π-Conjugated Functional Molecules and Materials

    Författare :Christian Dahlstrand; Henrik Ottosson; Miguel Solà; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fulvene; fulvalene; polyfulvene; aromaticity; triplet state; excited state; Clar structure; polybenzenoid hydrocarbons PBH ; conjugated polymers; computational chemistry; optical spectroscopy; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : The main focus of this thesis is on the aromaticity of the ground state and electronically excited states of π-conjugated molecules and polymers, as well as how aromaticity is connected to their properties.The electronic structures of polybenzenoid hydrocarbons (PBHs) were explored through density functional theory (DFT) calculations and the π-component of the electron localization function (ELFπ).

  4. 18. Membrane interactions of glycosyltransferases

    Författare :Jobst Liebau; Lena Mäler; Christofer Lendel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipid; bicelle; glycosyltransferase; NMR; Biophysics; biofysik;

    Sammanfattning : Many important biological processes occur near or in membranes. The role of membranes is not merely confined to compartmentalization, they also form the matrix for membrane associated proteins and are of functional importance. Membrane associated proteins on the other hand require specific membrane properties for proper function. LÄS MER

  5. 19. Metal Organic Frameworks: History, Synthesis, and Topological approach

    Författare :Cédric Borel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MOF; crystal structures; crystal engineering; network; coordination chemistry; synthesis; TOPOS; systre; gas storage;

    Sammanfattning : The storage, separation, purification and catalytic reactions of small molecules are important research domains in both pure and applied chemistry, where porous materials play a major role. Among the different possible options for the preparation porous materials a recent approach is to build structures based on metal ions, metal complexes, or metal clusters, bridged by organic ligands.

  7. 20. Fullerene-like carbon nitride thin solid films

    Författare :Jörg Neidhardt; Brian C. Holloway; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The subject of this thesis is to establish synthesis-structure-property- performance relations for nano structured carbon nitride thin solid films. This material consists of bent and frequently intersecting nitrogen-containing graphite basal planes, where nitrogen plays an important role for the initiation of inter-planar cross-links and the induction of curvature via pentagon formation, much like in Buckminster Fullerenes - hence, the terminology "fullerene-like carbon nitride".
