A NEXAFS study of thymine tautomers using coupled cluster methods
(Master thesis, 2018)The gas phase geometries of the thirteen different tautomers of thymine were optimized at the level of coupled cluster singles, doubles and perturbative triples, CCSD(T), using an aug-cc-pVDZ basis set. The total energy ... -
Nickel incorporated silica aerogels for the catalytic hydration of carbon dioxide.
(Master thesis, 2023)Denne oppgaven investigerer potensialet for å inkorporere nikkel i en silika aerogel atomisk og om en slik katalysator vil være aktiv for hydrering av karbondioksid. For å oppnå dette ble det brukt en optimalisert medforløper ... -
Nitrifying biofilms deprived of organic carbon show higher functional resilience to increases in carbon supply
(Peer reviewed; Journal article, 2020)In nitrifying biofilms, the organic carbon to ammonia nitrogen (C/N) supply ratio can influence resource competition between heterotrophic and nitrifying bacteria for oxygen and space. We investigated the impact of acute ... -

Nitropyridines in Organic Synthesis. 2.5-Disubstituted Pyridine Compounds
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:34, Doctoral thesis, 2004)The goal of this project was to explore how 5-nitropyridine-2-sulfonic acid (18) and its potassium salt (18a) could be utilised as starting materials for 2,5- substituted pyridines. Compounds 18/18a were prepared by oxidation ... -
Nitrous oxide and hydrogen sulfide production in sludge from a recirculating aquaculture system (RAS)
(Master thesis, 2021)Recirculating aquaculture systems (RAS) blir mer og mer vanlig, som svar på de økologiske og økonomiske problemene som finnes i oppdrettsnæringen. Sjøvann brukt i marine RAS er rikt på sulfat, og kombinert med organisk ... -
Non-equilibrium molecular dynamics simulations of the transient Ludwig-Soret effect in a binary Lennard-Jones/spline mixture
(Journal article, 2017)A binary isotope mixture of Lennard-Jones/spline particles at equilibrium was perturbed by a sudden change in the system's boundary temperatures. The system's response was determined by non-equilibrium molecular dynamics ... -
Non-equilibrium thermodynamics and nature-inspired chemical engineering applied to PEM fuel cells
(Doctoral theses at NTNU;2021:38, Doctoral thesis, 2021)The first objective of this thesis is to discover potentials for the optimisation of the performance of polymer electrolyte membrane (PEM) fuel cells by using new designs for the flow field plates (FFP) based on nature-inspired ... -
Non-equilibrium thermodynamics as a tool to compute temperature at the catalyst surface
(Journal article; Peer reviewed, 2019)The surface temperature is computed for a heterogeneous catalytic reaction model, namely the oxidation of carbon monoxide on platinum. The surface temperature was found using non-equilibrium thermodynamic theory, a theory ... -
Non-isothermal transport in cation-exchange membranes
(Master thesis, 2020)I denne masteroppgaven har seebeckeffekten blitt målt i ionebyttermembraner som er relevante for revers elektrodialyse (RED). Seebeckeffekten er elektrisk spenning som oppstår som følge av en temperaturgradient, og ... -
Non-isothermal transport of multi-phase fluids in porous media. Constitutive equations
(Journal article; Peer reviewed, 2019)We define a representative elementary volume of a porous medium in terms of lumped extensive variables, including properties of homogeneous phases, interfaces, and contact lines. Using the grand potential, we define the ... -
Non-isothermal transport of multi-phase fluids in porous media; The entropy production
(Journal article; Peer reviewed, 2018)We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Thermodynamic extensive variables on the ... -
Non-target analysis of chemicals extracted and migrated from plastic food contact articles
(Master thesis, 2022)Produksjonen av plast er stadig økende, og i dag blir plast brukt til alle slags formål, deriblant til produkter som skal være i kontakt med mat (FCA). For å gi plasten ønskede egenskaper, blir mange tilsetningsstoffer ... -
Non-target Screening of Emerging Organic Pollutants in Siberian Sediments
(Master thesis, 2023)Til tross for sin avsidesliggende beliggenhet, er Arktis i økende grad truet av forurensning, særlig fra kjemisk avrenning. I lys av dette undersøker denne studien både målrettede og ikke-målrettede analytiske metoder, og ... -
