From waste to bio-oil : Hydrothermal liquefaction of digested sewage sludge in small and large scale
(Doctoral thesis, 2023-06-16)FN’s bærekraftsmål er tydelige på hvilke tiltak som er nødvendige for å drastisk redusere de pågående klimaendringene i verden. Blant disse tiltakene finner man målet om bedre utnyttelse av bærekraftige råstoff, å sørge ... -
Functionalization of the Imidazole Backbone by Means of a Tailored and Optimized Oxidative Heck Cross-Coupling
(Journal article; Peer reviewed, 2020)A general and selective Pd-catalyzed cross-coupling of aromatic boronic acids with vinyl-imidazoles is disclosed. Unlike most cross-coupling reactions, this method operates well in absence of bases avoiding the formation ... -
Gas Chromatography optimization using experimental design and surface response methodology.
(Master thesis, 2018-10-25)Gas Chromatography (GC) is an analytical method for the separation of enormous range of routine applications, to analyse very complex mixtures of Petroleum, such us different proteins in the human body, and natural products. ... -
Gas phase models of hydride transfer from divalent alkaline earth metals to CO2 and CH2O
(Journal article; Peer reviewed, 2023)The reactivity of HMg+, HMgCl, and HMgCl2− in hydride transfer reactions with CO2 and CH2O were studied by means of the reverse reactions—decarboxylation of HCO2MgCln+/0/− and deformylation of CH3OMgCln+/0/− (n = 0–2)—by ... -
Geometric Frustration on the Trillium Lattice in a Magnetic Metal-Organic Framework
(Journal article; Peer reviewed, 2022)In the dense metal-organic framework Na[Mn(HCOO)3], Mn2+ ions (S=52) occupy the nodes of a “trillium” net. We show that the system is strongly magnetically frustrated: the Néel transition is suppressed well below the ... -
GLORY: Generator of the structures of likely cytochrome P450 metabolites based on predicted sites of metabolism
(Peer reviewed; Journal article, 2019-06-12)Computational prediction of xenobiotic metabolism can provide valuable information to guide the development of drugs, cosmetics, agrochemicals, and other chemical entities. We have previously developed FAME 2, an effective ... -
GRANADA consensus on analytical approaches to assess associations with accelerometer-determined physical behaviours (physical activity, sedentary behaviour and sleep) in epidemiological studies
(Journal article; Peer reviewed, 2021)The inter-relationship between physical activity, sedentary behaviour and sleep (collectively defined as physical behaviours) is of interest to researchers from different fields. Each of these physical behaviours has been ... -
Hit Dexter 2.0: Machine-Learning Models for the Prediction of Frequent Hitters
(Journal article; Peer reviewed, 2019)Assay interference caused by small molecules continues to pose a significant challenge for early drug discovery. A number of rule-based and similarity-based approaches have been derived that allow the flagging of potentially ... -
Hydrothermal liquefaction of sewage sludge anaerobic digestate for bio-oil production: Screening the effects of temperature, residence time and KOH catalyst
(Journal article; Peer reviewed, 2022)Due to sewage sludge being an abundant biobased resource, and with the number of biogas plants utilizing sewage sludge increasing, digested sewage sludge (DSS) is a promising feedstock for producing bio-oil. This study ... -
Identification and quantification of valuable platform chemicals in aqueous product streams from a preliminary study of a large pilot-scale steam explosion of woody biomass using quantitative nuclear magnetic resonance spectroscopy
(Journal article; Peer reviewed, 2022)Steam explosion breaks down the polymeric matrix and enables the recovery of valuable compounds from lignocellulosic feedstock. In the steam explosion process, biomass is treated with high-pressure steam which subsequently ... -
Identification of a Phage Display-Derived Peptide Interacting with the N-Terminal Region of Factor VII Activating Protease (FSAP) Enables Characterization of Zymogen Activation
(Journal article; Peer reviewed, 2022)Factor VII Activating protease (FSAP) has a protective effect in diverse disease conditions as inferred from studies in FSAP–/– mice and humans deficient in FSAP activity due to single-nucleotide polymorphism. The zymogen ... -
Ikkje god, ikkje dårleg, men berre OK. Det er bra. Ei kvalitativ studie om etterarbeid ved vurderingar i kjemifaget i vidaregåande skule
(Master thesis, 2011-05-30)This thesis is mainly based on my interviews of four chemistry teachers and nine chemistry pupils. The goal of the thesis is to find out how teachers and pupils continue working with a subject after the pupils has been ... -
Imidazole Backbone Functionalization with Olefin Cross-Metathesis
(Journal article; Peer reviewed, 2022)A selective and high-rate Ru-catalyzed cross-metathesis reaction of alkenes with vinylimidazole is disclosed. Cross-metathesis is known to operate less efficiently on N-heterocycles, but through optimization by means of ... -
Immiscible Viscous Fingering: Modelling Unstable Water–Oil Displacement Experiments in Porous Media
(Journal article; Peer reviewed, 2022)Viscous fingering in porous media occurs when the (miscible or immiscible) displacing fluid has a lower viscosity than the displaced fluid. For example, immiscible fingering is observed in experiments where water displaces ... -
Impact assessment culture in the European Union. Time for something new?
(Journal article; Peer reviewed, 2023)Current approaches and cultures for the economic evaluations of environmental and health policies may suffer from excessive reliance on a standard neoclassic economic toolbox that neglects alternative perspectives. This ... -
