(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Two high-mass polar compounds were observed in aqueous side-fractions from the purification of okadaic acid (1) and dinophysistoxin-2 (2) from Dinophysis blooms in Spain and Norway. These were isolated and shown to be ...
-
(Master thesis / Masteroppgave, 2018)About 5% of solar radiation comes from the ultraviolet (UV) region. It carries high energy and can do serious damage to living organisms. The eye of animals and humans is a critically exposed area and contains UV absorbing ...

Immunocapture of oxytocin followed by liquid chromatography-mass-spectrometric detectionRestricted Access (Master thesis / Masteroppgave, 2019)
-
(Master thesis / Masteroppgave, 2018)Fillers are used in coating and composite materials to enhance or introduce new properties. Deterioration of certain properties have been explained by a lack of interactions between the polymer and the filler. The interactions ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Here, we report the synthesis and magnetic properties of a novel, centrosymmetric, quasi-1D spin chain system La3VWS3O6, with hexagonal crystal structure (P63/m, a = 9.460 76(3), c = 5.518 09(2) Å). Pure powders were ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)In the present study, a series of H-ZSM-22 mesoporous catalysts resulting from three different desilication treatments (NaOH treatment, treatment using mixtures of NaOH/CTAB and using mixtures of NaOH/TBAOH) and sequential ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Non-alcoholic fatty liver disease (NAFLD) is a very common indication for liver transplantation. How fat-rich diets promote progression from fatty liver to more damaging inflammatory and fibrotic stages is poorly understood. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this work, impedance spectroscopy has been employed to explore the electrochemical behaviour of a 15 cm2 complete tubular cell with BaZr0.8Ce0.1Y0.1O3-δ (BZCY) electrolyte and two asymmetric Ni-BCZY cermet electrodes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We herein report an impedance spectroscopy study of Au electrodes on Gd-doped CeO2 (GDC) – molten Li2CO3+Na2CO3 (LNC) composite electrolytes in O2 and O2+CO2 atmospheres. Complementary measurements of Au on GDC alone are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Polychlorinated biphenyls (PCBs) are persistent organic compounds that are ubiquitously found in the environment. Their use and manufacture were restricted or banned in many countries in the 1970±1980s, however, they still ...

Importance of Val567 on heme environment and substrate recognition of neuronal nitric oxide synthase (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Nitric oxide (NO) produced by mammalian nitric oxide synthases (mNOSs) is an important mediator in a variety of physiological functions. Crystal structures of mNOSs have shown strong conservation of the active‐site residue ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)2-Aminobiphenyl palladacycles are among the most successful precatalysts for Pd-catalyzed cross-coupling reactions, including aryl amination. However, the role of NH-carbazole, a byproduct of precatalyst activation, remains ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In a solid-liquid dual-phase CO2 separation membrane, the native ions in the molten alkali carbonate, including carbonate anions and metal cations can transport CO2 in a process that is charge-compensated by electronic ...
