A procedure to find thermodynamic equilibrium constants for CO2 and CH4 adsorption on activated carbon
(Journal article; Peer reviewed, 2015)Thermodynamic equilibrium for adsorption means that the chemical potential of gas and adsorbed phase are equal. A precise knowledge of the chemical potential is, however, often lacking, because the activity coefficient of ... -
A robust method to calculate the volume phase transition temperature (VPTT) for hydrogels and hybrids
(Journal article; Peer reviewed, 2017)Here, we report three different methods to determine the volume phase transition temperature (VPTT) of various systems including poly(N-isopropylacrylamide) (pNIPAm) based nanogels, Au nanoclusters and a combination of ... -
A sensitive and compact optical detector based on digital lock-in amplification
(Peer reviewed; Journal article, 2021)We report a sensitive, fixed-wavelength, lock-in-based optical detector built from a light-emitting diode, two colour filters, a photodetector, a small number of discrete analogue components, and a low-cost microcontroller ... -
A simple synthetic route to methyl 3-fluoropyridine-4-carboxylate by nucleophilic aromatic substitution
(Journal article; Peer reviewed, 2006)The nitro group of methyl 3-nitropyridine-4-carboxylate (1) has successfully been replaced by fluoride anion via nucleophilic aromatic substitution to give the 3-fluoropyridine- 4-carboxylate 2. -
A study of carbonaceous aerosols in the Norwegian environment, focusing on the water-soluble organic carbon fraction
(Doctoral thesis, 2005)The aim of the present thesis was to study the carbonaceous fraction of ambient aerosols in the Norwegian environment, with a particular focus on the water-soluble carbonaceous fraction. Studies were based on bulk and ... -

A study of size fractions of metals in sedimented tunnel wash water
(Master thesis, 2020)Hensikten med dette prosjektet var å undersøke hvilke størrelsesfraksjoner av forskjellige metaller som er tilstede i vaskevann fra vegtunneler med et hovedmål om å utvikle en behandlingsstrategi for tunnelvaskevann. Dette ... -
A Study of the Entropy Production in Liquid Phase Shock Waves
(Master thesis, 2022)Vi har simulert en sjokkbølge i væskefase ved bruk av Non-Equilibrium Molecular dynamics (NEMD) og Navier-Stokes (N-S) ligningene. Den nye anvendelsen av N-S ligningene kombinerte en tilstandslikning (EOS) for et ... -
A study of the potential of mRNA vaccines against disease
(Bachelor thesis, 2021)I over to århundrer har vaksinasjoner forhindret utallige sykdommer og reddet utallige liv. Til tross for konstant fremgang av vaksineteknologi, utgjør sykdommer fortsatt en alvorlig risiko. Heldigvis finnes det et alternativ ... -
A Study of Thymine to Support Experimentalists - Interaction Energies and Core Ionisation Energies
(Master thesis, 2016)This thesis aims at investigating the interaction energies between two thymine molecules at different geometries, discussing select wave function based approaches for finding interaction energies, and looking closer at the ... -
A study on the Cytochrome P450 catalyzed production of (S)-perillyl alcohol from (S)-limonene
(Master thesis, 2020)Abstract will be available on 2023-06-01 -
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
(Journal article; Peer reviewed, 2008)It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have a long residence time ... -
A theoretical and experimental benchmark study of core-excited states in nitrogen
(Journal article; Peer reviewed, 2018)The high resolution near edge X-ray absorption fine structure spectrum of nitrogen displays the vibrational structure of the core-excited states. This makes nitrogen well suited for assessing the accuracy of different ... -
A thermodynamic study of the hydrogen dissociation by the Small System Method and the reactive force field ReaxFF
(Master thesis, 2016)The aim of this thesis was to study the reaction 2H=H2 using the reactive interaction potential ReaxFF. This was done by performing a thermodynamic study, using the ReaxFF and the Small System Method (SSM). The results ... -
Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
(Peer reviewed; Journal article, 2020)Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies ... -
