  1. 1. Evolution of biological systems linked to complex cell architectures in Planctomycetota

    Författare :Emil Hägglund; Siv Andersson; Damien Devos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Planctomcyetota; Cellular complexity; Gemmataceae; Phagocytocis; Serine Threonine kinase; Anammox; Hydrazine Synthase; Hydroxylamine oxidoreductase; Heme biosynthesis; Phylogenetics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : The eukaryotic cells have a nucleus and membrane-enclosed organelles for functions such as energy production, whereas the prokaryotic cells have a cell wall but no intracellular membrane-bound structures. Species of the Planctomycetota phylum are classified as bacteria but have diverse and complex cell architectures. LÄS MER

  3. 2. Structural chemistry and optical application

    Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjugated polymers; single crystal x-ray diffraction; porphyrins; NLO-materials;

    Sammanfattning : The demand for materials with optical activities against LASER radiation has been extensively increased over the last decade with the development of sophisticated high energetic LASER sources. The goal is to obtain organic or metal-organic molecules capable of increasing their absorptions against LASER irradiance while still maintaining a degree of transmittance. LÄS MER

  4. 3. Character and Function of Anammox Bacteria under Environmental Stress

    Författare :Ola Bäckman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anammox; N-cycle; environmental stress; redox oscillations; anammoxosome; key proteins;

    Sammanfattning : During the last few decades observations of novel processes involved in nitrogen transformations have fundamentally challenged the view of pathways and controlling mechanisms during local and global nitrogen cycling. Anaerobic ammonium oxidation (anammox) constitutes one of these new pathways where autotrophic bacteria oxidize ammonium by nitrite to dinitrogen gas under anaerobic conditions. LÄS MER

  5. 4. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER

  7. 5. Bispidine Derivatives : Synthesis and Interactions with Lewis Acids

    Författare :Lauri Toom; Adolf Gogoll; Helena Grennberg; Frode Rise; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; bispidines; NMR; basicity; structural information; palladium; complexes; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : In this thesis, the improved synthesis and investigations into the properties of some 3,7-diazabicyclo[3.3.1]nonane (bispidine) derivatives are described. LÄS MER
