Revised Enskog theory and extended corresponding states models for the transport properties of the Lennard-Jones/spline fluid
(Master thesis, 2025)Fluider som består av partikler som interagerer via parpotensialer er forenklede, men mye anvendte modeller av reelle fluider. Disse modellfluidene er nyttige for å utvikle teorier og modeller som senere kan anvendes for ... -
Identification of polar bioactive substances in the Upper Rhine using effect-directed analysis
(Journal article; Peer reviewed, 2025)Effect-Directed Analysis (EDA) was used to identify bioactive compounds in surface and well water from the Upper Rhine, and to evaluate their properties against the criteria set for Persistent, Mobile and Toxic (PMT) and ... -
Impact of seawater temperature and physical-chemical properties on sorption of pharmaceuticals, stimulants, and biocides to marine particles
(Peer reviewed; Journal article, 2024)Pharmaceuticals, stimulants, and biocides enter the environment via wastewater from urban, domestic, and industrial areas, in addition to sewage, aquaculture and agriculture runoff. While some of these compounds are easily ... -
Occurrence, bioaccumulation and trophic dynamics of per- and polyfluoroalkyl substances in two tropical freshwater lakes
(Journal article; Peer reviewed, 2024)We have investigated the occurrence, distribution, and biomagnification of per- and polyfluoroalkyl substances (PFAS) in two tropical lakes (Asejire and Eleyele) of Southwestern Nigeria, with contrasting urban intensities. ... -
Role of niche and micro-habitat preferences in per- and polyfluoroalkyl substances occurrence in the gills of tropical lake fish species
(Peer reviewed; Journal article, 2024)The present study has investigated per- and poly-fluoroalkyl substances (PFAS) in the gill tissues of various fish species inhabiting different trophic levels within Eleyele Lake, a tropical freshwater lake in Nigeria. The ... -
The effect of temperature constraints on the treatment of tumors using focused ultrasound-induced acoustic streaming
(Peer reviewed; Journal article, 2025)The transport of drugs into tumor cells near the center of the tumor is known to be severely hindered due to the high interstitial pressure and poor vascularization. The aim of this work is to investigate the possibility ... -
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
(Peer reviewed; 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 ... -
