Physical properties and reaction kinetics of CO2 absorption into unloaded and CO2 loaded viscous monoethanolamine (MEA) solution
(Journal article, 2021)In order to comprehensively understand how solvent free concentration and high viscosity affect mass transfer and consequently absorption flux, CO2 absorption kinetics into unloaded and CO2 loaded viscous monoethanolamine ... -
Vapor liquid equilibrium of pure and aqueous Methyl diethanolamine (MDEA), 2-Dimethylmonoethanolamine (DMMEA), N-Methylmonoethanolamine (MMEA) and 1-(2-Aminoethyl)piperazine (AEP): Experimental results and modeling
(Peer reviewed; Journal article, 2023)This work presents new vapor-liquid data for the pure components 2-dimethylmonoethanolamine (DMMEA) and N-methylethanolamine (MMEA) and for the binary systems of aqueous methyldiethanolamine (MDEA), DMMEA, MMEA, and ... -
Modeling the Effect of Excess Vacancies on Precipitation and Mechanical Properties of Al–Mg–Si Alloys
(Peer reviewed; Journal article, 2023)A model for vacancy annihilation during aging has been combined with a precipitation model for coupled nucleation, growth, and coarsening in AA 6xxx series aluminum alloys. The simulation results were compared with ... -
Introduction of Potassium Iodide as an Inhibitor for Oxidative Degradation of Amines
(Chapter, 2021)Oxidative degradation of amines for CO2 capture is a challenge that has yet to be overcome. This work presents the potential of using potassium iodide as a stable inhibitor, potentially without the need for replenishment ... -

Mechanisms and evolution of thermal tolerance in fish
(Doctoral theses at NTNU;2023:392, Doctoral thesis, 2023)Global temperatures are rising and heat waves are becoming more frequent, reaching higher temperatures, and lasting longer. Many animals are living close to their limits for warming tolerance and mass mortality events are ... -
Experimental Assessment of the Environmental Impact of Ethanolamine
(Chapter, 2021)The environmental impact of ethanolamine, a common amine for carbon dioxide capture, was experimentally investigated in laboratory scale microcosms. By exposing the plant-soil systems to varying amounts of ethanolamine, ... -
Nanoscale Chemical Analysis of Ferroic Materials and Phenomena
(Doctoral theses at NTNU;2023:397, Doctoral thesis, 2023)The discovery of new physical phenomena in materials is closely linked to the progress in characterization and is propelled by the ability to observe and study physical processes occurring at the atomic level. Newly ... -
Restriction spectrum imaging with elastic image registration for automated evaluation of response to neoadjuvant therapy in breast cancer
(Peer reviewed; Journal article, 2023)Purpose: Dynamic contrast-enhanced MRI (DCE) and apparent diffusion coefficient (ADC) are currently used to evaluate treatment response of breast cancer. The purpose of the current study was to evaluate the three-component ... -
Describing posterior distributions of variance components: Problems and the use of null distributions to aid interpretation
(Peer reviewed; Journal article, 2023)1. Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)-based mixed-effects models is not straightforward. Variance estimates are constrained to be greater than zero and ... -
Catalyst Development of Ethylene Oxychlorination to Ethylene Dichloride and Vinyl Chloride
(Doctoral theses at NTNU;2023:372, Doctoral thesis, 2023)Vinyl chloride monomer (VCM) is a critical component in the production of polyvinyl chloride (PVC), one of the most extensively used plastic polymers, through the polymerization process. The global VCM industry capacity ... -
Macro- and micro scale phenomena in gas flotation for produced water treatment- the effect of fluid composition, temperature and pressure
(Doctoral theses at NTNU;2023:369, Doctoral thesis, 2023)Produced water, the primary waste product of the petroleum industry, contains harmful components that must be treated before discharge to the sea or reinjection. The focus of treatment has traditionally been on dispersed ... -
Enhanced grain growth and dielectric properties in aerosol deposited BaTiO3
(Peer reviewed; Journal article, 2023)Piezoelectric ceramics are envisioned as cell stimulating materials for in-vivo, load-bearing applications. To compensate for their brittle nature developing ceramic films on medically accredited metals is a promising ... -
Moon phase and season alter road use by lions
(Peer reviewed; Journal article, 2023)Roads within protected areas facilitate management and tourism but can also alter animal movements and foraging opportunities. Animal tracks observed along roads are also used to index species distributions and abundance. ... -
Topological superconductivity mediated by magnons of helical magnetic states
(Peer reviewed; Journal article, 2023)We recently showed that spin fluctuations of noncoplanar magnetic states can induce topological superconductivity in an adjacent normal metal [Mæland et al., Phys. Rev. Lett. 130, 156002 (2023)]. The noncolinear nature of ... -
A species-level trait dataset of bats in Europe and beyond
(Peer reviewed; Journal article, 2023)Knowledge of species’ functional traits is essential for understanding biodiversity patterns, predicting the impacts of global environmental changes, and assessing the efficiency of conservation measures. Bats are major ... -
Circular economy for aquatic food systems: insights from a multiscale phosphorus flow analysis in Norway
(Peer reviewed; Journal article, 2023)As wild-caught fish become scarce, feed ingredients for farming fish, such as salmon, are increasingly sourced from agricultural plants that depend on mineral fertilizers. Since these fish are naturally carnivorous, they ... -
Comparative kinetics study of different iron-containing pellets with hydrogen at isothermal conditions
