Origin and spatial distribution of metals in moss samples in Albania: A hotspot of heavy metal contamination in Europe
(Journal article; Peer reviewed, 2018)This study presents the spatial distribution of 37 elements in 48 moss samples collected over the whole territory of Albania and provides information on sources and factors controlling the concentrations of elements in the ... -
Oxidative degradation of triethylene glycol
(Journal article; Peer reviewed, 2024)Triethylene glycol (TEG) is unstable in the presence of oxygen and at high temperatures, though the degradation mechanisms occurring are not properly understood. In attempting to close some of the knowledge gaps, ... -
Oxygen and related defects in Czochralski silicon crowns
(Master thesis, 2014)For the purpose of this thesis work, four n-type CZ silicon ingots with different crown tapered angle and shouldering area were characterized in order to understand the oxygen behavior and related defects on ingot top cuts ... -
Oxygenate conversion over protonated zeolites.
(Master thesis, 2013)In this thesis, a number of commercial zeolites and a silicalite have been characterised using transmission FT-IR in a vacuum cell. The samples were then investigated in situ by DRIFTS during methanol conversion at 350oC, ... -
Palladium Catalyzed Cross-Coupling Reactions on 7-Azaindoles in the Synthesis of CSF1R Inhibitors
(Master thesis, 2019)Overuttrykk av colony stimulating factor 1 receptor (CSF1R) tyrosin kinase er blitt linket til flere sykdommer, blant annet kreft, benosteolyse og betennelseslidelser. En lovende behandlingsstrategi for disse sykdommene ... -
Palladium(0)-Catalyzed Cross-Couplings of 2-Bromophosphinine
(Journal article; Peer reviewed, 2013)A new Negishi-type cross-coupling of 2-bromophosphinine has been developed. The new method expands the scope of palladium-catalyzed couplings to monobromophosphinines, which have been considered as poor substrates so far. ... -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
(Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ... -
Parabens and triclocarban in baby foodstuffs
(Master thesis, 2020)For forbrukersikkerhet og kvalitetssikring av forbrukerartikler, er tilsetning av bakteriebekjempende kjemikalier strengt regulert, både med hensyn på merking og mengde. Alkylestere av parahydroksibenzosyre, kalt parabener, ... -
Parameters Governing the Adsorption of Crude and Bunker Fuel Oils to Seawater Suspended Particulate Matter
(Master thesis, 2012)In this study, parameters influencing the adsorption of dispersed oil droplets to suspended particulate matter (SPM) in seawater were investigated. The interaction between oil and SPMs can alter the ultimate fate of oil ... -
Parametrization of a classical force field model (CT-PDI) for the calculation of molecular polarizablities
(Master thesis, 2023)To parametriseringer av en klassisk elektrostatisk modell for polariserbarheten er blitt gjennomført. Parametriseringene er gjennomført på et stort sett av små organiske molekyler, med mange vanlige funksjonelle grupper. ... -
Part A: Investigations of Sodium-Graphite InteractionPart B: Structures and conformational Energies of 1,2- Dihaloethane and Silane AnaloguesPart C: Development of Ab Initio computational Methods based on non-orthogonal Slater Determinants
(Master thesis, 2011)Part A:Cathode wear is the limiting factor in the lifetime of electrolytic cells in aluminium production. One important reason for wear in carbon cathode materials is the penetration and diffusion of sodium from the melt, ... -
Particulate Iron Bioavailability to Phytoplankton in Antarctic and Arctic Waters: Effects of Ocean Acidification and the Organic Ligand EDTA
(Master thesis, 2021)Particulate iron (PFe) usually is not considered as a bioavailable iron fraction to phytoplankton. In this study we tested the bioavailability of one PFe species, goethite (α-FeO(OH)), to phytoplankton community in Southern ... -
