Computational study of the dissolution of cellulose into single chains: the role of the solvent and agitation
(Journal article; Peer reviewed, 2022)We investigate the dissolution mechanism of cellulose using molecular dynamics simulations in both water and a mixture solvent consisting of water with Na+, OH− and urea. As a first computational study of its kind, we apply ... -
Four different benzimidazoles as treatment against Encephalitozoon cuniculi infection in rabbits and how they may bind to β-tubulin
(Bachelor thesis, 2022)Encephalitozoon cuniculi infeksjon i kjæledyr- og laboratoriekaniner er et pågående problem som kan føre til alvorlig sykdom og død hos kaninene. Behandling av den parasittiske infeksjonen innebærer hovedsakelig doser av ... -
The thermal boundary resistance at semiconductor interfaces: a critical appraisal of the Onsager vs. Kapitza formalisms
(Journal article; Peer reviewed, 2018)We critically readdress the definition of thermal boundary resistance at an interface between two semiconductors. By means of atomistic simulations we provide evidence that the widely used Kapitza formalism predicts thermal ... -
Thin film breakage in oil–in–water emulsions, a multidisciplinary study
(Peer reviewed; Journal article, 2022)Coalescence is a critical phenomenon in separation and transport processes. An improved understanding of coalescence can enhance current models predicting emulsion stability and separation. We here report a combined ... -
Heat to Hydrogen by RED—Reviewing Membranes and Salts for the RED Heat Engine Concept
(Peer reviewed; Journal article, 2022)The Reverse electrodialysis heat engine (REDHE) combines a reverse electrodialysis stack for power generation with a thermal regeneration unit to restore the concentration difference of the salt solutions. Current approaches ... -
Occurrence and sorption behaviour of bisphenols and benzophenone UV-filters in e-waste plastic and vehicle fluff
(Journal article; Peer reviewed, 2021)Bisphenols and benzophenone UV-filters are hazardous, high production volume chemicals. There is concern that these contaminants could leach into the environment or be recycled into new products during waste management. ... -
The development of antifouling materials with potential application on sensors
(Doctoral theses at NTNU;2022:77, Doctoral thesis, 2022)Unwanted biofilm is one of major unsolved problems for underwater structures including movable and stationary, such as ships, pipelines, cables, fishing nets, bridge pillars and sensors. Especially for water monitoring ... -
Skogholt’s disease—A tauopathy precipitated by iron and copper?
(Peer reviewed; Journal article, 2022)Background It has been suggested that Skogholt’s disease is a new neurological disease entity. The disease, confined to a family line in Hedmark county, Norway, usually affects both the brain and peripheral nerves. Typical ... -
Effects of Organic Carbon Origin on Hydrophobic Organic Contaminant Fate in the Baltic Sea
(Peer reviewed; Journal article, 2021)The transport and fate of hydrophobic organic contaminants (HOCs) in the marine environment are closely linked to organic carbon (OC) cycling processes. We investigated the influence of marine versus terrestrial OC origin ... -
Burst Dynamics, Upscaling and Dissipation of Slow Drainage in Porous Media
(Peer reviewed; Journal article, 2021)We present a theoretical and experimental investigation of drainage in porous media. The study is limited to stabilized fluid fronts at moderate injection rates, but it takes into account capillary, viscous, and gravitational ... -

Carbonaceous materials for single-use sensors. Quality assessment by electrochemical impedance spectrometry
(Chapter, 2005)An overview of achievements and prospects of electrochemical impedance spectrometry (EIS) application for characterizing the surface of the carbon paste electrode (CPE) is emphasized. Several guidelines are pointed out and ... -
Using thiourea as source for electrochemical generation of metal sulfides
(Journal article; Peer reviewed, 2008) -
Small Size Effects in Open and Closed Systems: What Can We Learn from Ideal Gases about Systems with Interacting Particles?
(Peer reviewed; Journal article, 2021)Small systems have higher surface area-to-volume ratios than macroscopic systems. The thermodynamics of small systems therefore deviates from the description of classical thermodynamics. One consequence of this is that ... -
Fate of Springtime Atmospheric Reactive Mercury: Concentrations and Deposition at Zeppelin, Svalbard
(Peer reviewed; Journal article, 2021)Mid-latitude atmospheric elemental mercury (Hg) emissions undergo extensive oxidation to reactive Hg (RM) compounds during Arctic polar sunrise, resulting in enhanced atmospheric deposition that impacts Arctic marine ... -
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 ... -
Cathodic stripping voltammetry of homocysteine and the respective thiolactone at a mercury electrode

Effects of leachates from UV-weathered microplastic on the microalgae Scenedesmus vacuolatus
(Peer reviewed; Journal article, 2021)Plastics undergo successive fragmentation and chemical leaching steps in the environment due to weathering processes such as photo-oxidation. Here, we report the effects of leachates from UV-irradiated microplastics towards ... -
Efficient algorithms for coupled cluster with approximate triples for larger molecular systems
(Doctoral theses at NTNU;2021:339, Doctoral thesis, 2021)Spectroscopic techniques are widely used to study matter in a non-invasive manner. With increasing complexity of the experiments conducted, theoretical simulations become more important to gain additional insight into the ... -
