    Platycodon grandiflorus is a plant widely used in traditional Chinese medicine, of which polysaccharides are reported to be the main components responsible for its bio-functions. In this work, the inulin-type fructan (PGF) ...
  • Skjærvø, Øystein (Master thesis / Masteroppgave, 2016)
    The structure, thickness and characteristics of liquid chromatography (LC) column materials are central factors regarding their performance. However, miniaturized capillaries (sub 20.0 μm inner diameter, typically used for ...
  • Kvellestad, Anders (Doctoral dissertation / Doktoravhandling, 2015)
    In this thesis we explore several physics scenarios based on the Minimal Supersymmetric Standard Model (MSSM) and its extension in terms of Rparity violation. We derive predictions for, and analyse results from, the ongoing ...

    To improve lithium and sodium ion battery technology, it is imperative to understand how the properties of the different components are controlled by their chemical structures. Operando structural studies give us some of ...
  • Desissa, Temesgen D.; Kanas, Nikola; Singh, Sathya Prakash; Wiik, Kjell; Einarsrud, Mari-Ann; Norby, Truls Eivind (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Diffusivity on the A- and B-site of polycrystalline perovskite CaMnO3-δ with Ca deficiency and spinel CaMn2O4 (marokite) as a secondary phase was studied using chemical tracers and secondary ion mass spectrometry (SIMS) ...
  • Sønsteby, Henrik Hovde; Nilsen, Ola; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Potassium sodium niobate (KNN) has long been considered a viable candidate for replacing lead‐based materials in piezo‐ and ferroelectric devices. The introduction of KNN on an industrial scale is highly awaited; however, ...
  • Tellgren, Erik; Kvaal, Simen; Sagvolden, Espen; Ekström, Ulf Egil; Teale, Andrew Michael; Helgaker, Trygve (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    The selection of basic variables in current-density-functional theory and formal properties of the resulting formulations are critically examined. Focus is placed on the extent to which the Hohenberg-Kohn theorem, ...
  • Aass, Cecilie (Master thesis / Masteroppgave, 2013)
    Phosphatidylinositol phosphates (PIPs) are phospholipids (PLs) that play fundamental roles as signaling molecules in numerous cellular processes. However, PIPs have shown to be perhaps some of the most challenging compounds ...
  • Valiev, Rashid R.; Fliegl, Heike; Sundholm, Dage (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Magnetizabilities and magnetically induced ring-current strength susceptibilities have been calculated at the Hartree–Fock, density functional theory and second order Møller–Plesset levels for a number of antiaromatic ...
  • Frøen, Emil Herman (Master thesis / Masteroppgave, 2019)
    NiO and ZnO are a pair of p- and n-type wide band gap metal oxide semiconductors that forms a partially soluble system with each other. Due to these properties, they are considered a potential semiconductor pair for the ...
  • Nielsen, Malte; Hafreager, Anders; Brogaard, Rasmus Yding; De Wispelaere, Kristof; Falsig, Hanne; Beato, Pablo; Van Speybroeck, Veronique; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    When exposed to steam, zeolite catalysts are irreversibly deactivated by loss of acidity and framework degradation caused by dealumination. Steaming typically occurs at elevated temperatures, making it challenging to ...
  • Vehus, Tore; Waaler, Jo; Krauss, Stefan; Lundanes, Elsa; Wilson, Steven Ray Haakon (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Fluorescence polarization (FP) is a highly regarded technique for studying drug–protein interactions, but has limited value regarding protein mixtures. As a novel approach to drug target discovery, the possibility of ...
  • Karazhanov, Smagul; Kroll, P; Holt, A; Bentzen, A; Ulyashin, Alexander (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)
    We present a study of the electronic structure and optical properties of Si3N4 and Si2N3H in crystalline and amorphous phases by first-principles calculations. We find that besides structural disorder those matrix atoms ...
  • Evensen, Kjetil Gurholt (Master thesis / Masteroppgave, 2014)
    With large countries as India and China in tremendous development accompanied by a growing worldwide population, questions arise in how energy demands can be met in the post-oil society. The methanol-to-hydrocarbon process, ...
  • Vesterdal, Caroline (Master thesis / Masteroppgave, 2015)
    Oxysterols in biological samples of limited size are present in low concentrations thus sensitive methods are advantageous. Derivatization of oxysterols prior to liquid chromatography (LC) mass spectrometry (MS) analysis ...
