Design and Synthesis of Carbazole Derivatives as Novel Therapeutic Candidates Against Acute Myeloid Leukaemia
(Master thesis, 2023-11-20)Akutt myelogen leukemi (AML) er ein heterogen gruppe blodkreft, karakterisert ved ukontrollert vekst av celler i den myelogene celle linja. Denne sjukdomsgruppa er assosiert med låg overlevingsrate, særleg hos eldre pasientar ... -
Observasjoners rolle for refleksjoner og kritisk tenkning
(Master thesis, 2021-06-01)Det er økende fokus på kritisk tenkning og utforskende undervisning i den nye læreplanen (Utdanningsdirektoratet, 2019). I den anledning har jeg i denne masteroppgaven tatt utgangspunkt i problemstillingen: «Hvordan kommer ... -
Enabling Molecular-Level Computational Description of Redox and Proton-Coupled Electron Transfer Reactions of Samarium Diiodide
(Journal article; Peer reviewed, 2023)Samarium diiodide (SmI2, Kagan’s reagent) is a one-electron reductant with applications ranging from organic synthesis to nitrogen fixation. Highly inaccurate relative energies of redox and proton-coupled electron transfer ... -
Microplastics could be marginally more hazardous than natural suspended solids - A meta-analysis
(Journal article; Peer reviewed, 2023)Microplastics (MP) are perceived as a threat to aquatic ecosystems but bear many similarities to suspended sediments which are often considered less harmful. It is, therefore pertinent to determine if and to what extent ... -
Vertical distribution of inorganic nanoparticles in a Norwegian fjord
(Journal article; Peer reviewed, 2023)Due to the analytical challenges of detecting and quantifying nanoparticles in seawater, the data on distributions of NPs in the marine environment is limited to qualitative studies or by ensemble measurements subject to ... -
Quantitative Comparison against Experiments Reveals Imperfections in Force Fields’ Descriptions of POPC-Cholesterol Interactions
(Journal article; Peer reviewed, 2023)Cholesterol is a central building block in biomembranes, where it induces orientational order, slows diffusion, renders the membrane stiffer, and drives domain formation. Molecular dynamics (MD) simulations have played a ... -
Desorption of sulfamethoxazole from polyamide 6 microplastics: Environmental factors, simulated gastrointestinal fluids, and desorption mechanisms
(Journal article; Peer reviewed, 2023)Microplastics (MPs) can enrich pollutants after being released into the environment, and the contaminants-loaded MPs are usually ingested by organisms, resulting in a potential dual biotoxic effect. In this paper, the ... -
