First Principles Study of Bismuth Vacancy Formation in (111)-Strained BiFeO<inf>3</inf>
(Journal article; Peer reviewed, 2024)Epitaxial strain is known to significantly influence the structural and functional properties of oxide thin films. However, its impact on point defect concentration has been less explored. Due to the challenges in ... -
Snowmobiles as a potential local source of trace element and microplastic pollution in the Arctic
(Master thesis, 2025)Arktis blir ofte sett på som et øde og uberørt område. Til tross for dette finnes det lokale forurensningkilder her og det er viktig å øke kunnskapen om disse lokale kildene for å kartlegge et mer fullstendig bilde av ... -
Predicting ignitability of oil slicks for in-situ burning operations as a function of weathering and oil properties
(Journal article, 2024)In an In-Situ Burning (ISB) operation of a marine oil spill, igniting the oil is usually the critical step with emulsification as the main limiting factor. Several rules-of-thumbs exist to estimate ignitability based on ... -
Hyper-Ballistic Superdiffusion of Competing Microswimmers
(Peer reviewed; Journal article, 2024)Hyper-ballistic diffusion is shown to arise from a simple model of microswimmers moving through a porous media while competing for resources. By using a mean-field model where swimmers interact through the local concentration, ... -
Interpreting pore-scale fluctuations: Predicting transport coefficients in multiphase flow through porous media using the Green-Kubo formulation - An experimental investigation
(Peer reviewed; Journal article, 2024)Flow fluctuations that are commonly associated with multiphase flow in porous media are studied using concepts from non-equilibrium thermodynamic and statistical mechanics. We investigate how the Green–Kubo formulation of ... -
The nasal cavity of the bearded seal: An effective and robust organ for retaining body heat and water
(Journal article; Peer reviewed, 2024)We report the effects of varying physiological and other properties on the heat and water exchange in the maxilloturbinate structure (MT) of the bearded seal (Erignathus barbatus or Eb) in realistic environments, using a ... -
The impact of biochar's physicochemical properties on sorption of perfluorooctanoic acid (PFOA)
(Peer reviewed; Journal article, 2024)To better characterize properties governing the sorption of per- and polyfluoroalkyl substances (PFAS) to biochar, twenty-three diverse biochars were characterized and evaluated as sorbents for perfluorooctanoic acid (PFOA). ... -
Lattice Models in Molecular Thermodynamics: Merging the Configurational and Translational Entropies
(Journal article; Peer reviewed, 2024)Lattice models are a central idea in statistical thermodynamics, as they allow for the introduction of a configurational entropy by counting the multiplicity of placing indistinguishable particles on a lattice. In this ... -
Extrapolating into no man's land enables accurate estimation of surface properties with multiparameter equations of state
(Peer reviewed; Journal article, 2024)Thermodynamic properties of homogeneous fluids in the metastable and unstable regions are needed to describe confined fluids, interfaces, nucleating embryos and estimate critical mass flow rates. The most accurate equations ... -
Equation of State for Solid Argon Valid for Temperatures up to 300 K and Pressures up to 16 GPa
(Journal article; Peer reviewed, 2024)A new equation of state (EoS) is presented for solid argon. The EoS is based on the quasi-harmonic approximation and formulated in terms of the Helmholtz energy, with temperature and molar volume as independent variables. ... -
Per- and poly-fluoroalkyl substances (PFAS) do not accumulate with age or affect population survival in ruddy turnstone (Arenaria interpres)
(Journal article; Peer reviewed, 2024)Per- and poly-fluoroalkyl substances (PFAS) may threaten wildlife due to their high environmental persistence, toxicity potential and potential to bioaccumulate. Bioaccumulation may be particularly profound in long-lived ... -
The Global Threat from the Irreversible Accumulation of Trifluoroacetic Acid (TFA)
(Journal article; Peer reviewed, 2024)Trifluoroacetic acid (TFA) is a persistent and mobile substance that has been increasing in concentration within diverse environmental media, including rain, soils, human serum, plants, plant-based foods, and drinking ... -
Shellfish and shorebirds from the East-Asian Australian flyway as bioindicators for unknown per- and polyfluoroalkyl substances using the total oxidizable precursor assay
(Journal article; Peer reviewed, 2025)Per- and polyfluoroalkyl substances (PFAS) have gained significant global attention due to their extensive industrial use and harmful effects on various organisms. Among these, perfluoroalkyl acids (PFAAs) are well-studied, ... -
From mother to egg: Variability in maternal transfer of trace elements and steroid hormones in common eider (Somateria mollissima)
(Journal article; Peer reviewed, 2024)The Baltic Sea is among the most polluted seas worldwide with elevated concentrations of trace elements (TEs). TEs can induce negative effects on organisms and may be transferred to eggs causing endocrine-disrupting effects ... -
