  2. 1. Deposition and Resolution of AA Amyloid

    Author : Sofia N. Nyström; Gunilla T Westermark; Christoph Röcken; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AA-amyloid; autophagy; resolution; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Abstract : Amyloidosis is a group of protein misfolding diseases characterized by extracellulardeposition of fibrillar protein aggregates. Today more than 25 different human amyloidogenicproteins have been identified, causing a variety of pathological conditions that includeAlzheimer’s disease, type 2 diabetes and prion diseases.

  4. 2. Growth, Characterization, and Thermal Stability of CeO2 Thin Films

    Author : Sissel N. Jacobsen; David K. Fork; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Rare earth oxides are potentially useful materials in various optical electronic, and catalytic devices. The characteristics of such devices are strongly dependent on the interface structure of heterojunctions, hence engineering of the performance can be achieved through tailoring of the micro- and/ or surface structure.

  5. 3. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition

    Author : Michael Nordlund; Helena Grennberg; Mogens Brøndsted Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fullerenes; Graphene; Deposition; Functionalization; Organometallic complexes; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The work described in this thesis concerns development, synthesis and characterisation of new molecular compounds and materials based on the carbon allotropes fullerene (C60) and graphene.A stepwise strategy to a symmetric ferrocene-linked dumbbell of fulleropyrrolidines was developed.

  6. 4. Nitrogen, parasites and plants : key interactions in boreal forest ecosystems

    Author : Joachim Strengbom; Lars Ericson; Gaius R Shaver; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical loads; Deschampsia flexuosa; amino acids; mycorrhizal fungi; natural enemies; N deposition; N limitation; vegetational composition; Valdensia heterodoxa; Vaccinium myrtillus;

    Abstract : In the work described in this thesis I studied how increases in nitrogen (N) inputs may affect plant community structure in boreal forest understorey vegetation. These phenomena were investigated in N fertilization experiments and along a national N deposition gradient. READ MORE

  7. 5. Chemical vapor deposition of hard coatings : Development of W(C,N) coatings for cemented carbide and TiN deposition on a CoCrFeNi substrate

    Author : Katalin Böőr; Mats Boman; Markku Leskelä; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : There is a constant need for cutting tool material development to be able to machine new materials and improve the metal cutting efficiency. Inserts of indexable cutting tools usually consist of WC-Co cemented carbide (cc) with μm thick layers of ceramic coatings. READ MORE
