Carbon cycle feedbacks in an idealized simulation and a scenario simulation of negative emissions in CMIP6 Earth system models
(Journal article; Peer reviewed, 2024)Limiting global warming to well below 2 ∘C by the end of the century is an ambitious target that requires immediate and unprecedented emission reductions. In the absence of sufficient near-term mitigation, this target will ... -
Many-body effects on superconductivity mediated by double-magnon processes in altermagnets
(Journal article; Peer reviewed, 2024)Altermagnets exhibit a large electron spin splitting which can be understood as a result of strong coupling between itinerant electrons and localized spins. We consider superconductivity due to electron-magnon scattering, ... -
Effects of different live feeding regimes on the development and lipid composition of ballan wrasse (Labrus bergylta) larvae
(Master thesis, 2024)Lakselus (Lepeophtheirus salmonis) utgjør en av de største utfordringene for utvidelsen av norsk lakseoppdrett, og påvirker produksjonen, fiskevelferden og villaksbestandene negativt. Effektiviteten til både kjemiske og ... -
Topology-guided polar ordering of collective cell migration
(Peer reviewed; Journal article, 2024)The ability of epithelial monolayers to self-organize into a dynamic polarized state, where cells migrate in a uniform direction, is essential for tissue regeneration, development, and tumor progression. However, the ... -
LCA of recycling aluminium incineration bottom ash, dross and shavings in a rotary furnace and environmental benefits of salt-slag valorisation
(Peer reviewed; Journal article, 2024)Recycling aluminium in a rotary furnace with salt-fluxes allows recovering valuable alloys from hard-to-recycle waste/side-streams such as packaging, dross and incinerator bottom ash. However, this recycling route generates ... -
Optimization of Co-Ni-Mg-Al mixed-oxides CO2 methanation catalysts with solution combustion synthesis: On the importance of Co incorporation and basicity
(Peer reviewed; Journal article, 2023)Hydrogenation of CO2 to methane is a promising prospect for the utilization of carbon dioxide. Ni-Mg-Al mixed oxides have been reported as a catalyst for this process. Their promotion with cobalt allows to improve Ni ... -
Excess-Methane CO2 Reforming over Reduced KIT-6-Ni-Y Mesoporous Silicas Monitored by In Situ XAS–XRD
(Journal article; Peer reviewed, 2023)Making Europe less dependent on imported fuels requires a long-term strategy. Low-quality natural gas and biogas could be used to mitigate the energy crisis, and excess-methane dry reforming has the potential to upgrade a ... -
Stabilization of PFAS-contaminated soil with sewage sludge- and wood-based biochar sorbents

Advancing Spintronics through Ellipsometric Characterisation of Surface Polaritons
(Doctoral theses at NTNU;2024:133, Doctoral thesis, 2024)Spintronics is a subtopic of magnonics in which the spin of the electron is used to store and process information. Magnonics is the magnetic analogue of the recently popularised field of plasmonics, which deals with the ... -
Steady-State and Transient Kinetic Investigations of the Oxidation of NO over Pt/SiO2
(Journal article; Peer reviewed, 2024)The reaction mechanism of the oxidation of NO under conditions of high NO concentration over a 2 wt% Pt/SiO2 was studied using both kinetic and transient isotopic tracing experiments. The reaction mechanism was found to ... -
Exposure assessment of plastics, phthalate plasticizers and their transformation products in diverse bio-based fertilizers
(Peer reviewed; Journal article, 2024)Bio-based fertilizers (BBFs) produced from organic waste have the potential to reduce societal dependence on limited and energy-intensive mineral fertilizers. BBFs, thereby, contribute to a circular economy for fertilizers. ... -
Evaluating hyperspectral Secchi depth retrieval through hybrid modeling and regression
(Peer reviewed; Journal article, 2023)This work compares different regression models combined with hybrid modeling to estimate water clarity using hyper-spectral remote sensing data. The Secchi depth, a proxy of water clarity, can be modeled using first ... -
Gasskraftverk med CO2-håndtering - Studie av alternative teknologier
(Research report, 2002)Rapporten dokumenterer en studie som beskriver og sammenligner 12 ulike teknologier for gasskraftverk med CO2-håndtering. Merkostnaden for å fjerne CO2 i forbindelse med elektrisitetproduksjon er i studien beregnet til ... -
Currents in AC stressed liquid insulated needle plane gap
(Chapter, 2014)Currents and space charge phenomena in 8 different dielectric liquids have been investigated for an ac stressed needle plane gap. Applied frequencies ranged from 0.1 Hz to 100 Hz. A high resolution analogue-digital converter ... -
The Simple Solution for Nonlinear State Estimation of Ill-Conditioned Systems: The Normalized Unscented Kalman Filter
(Journal article; Peer reviewed, 2023)An easy-to-implement method for nonlinear state estimation for ill-conditioned systems is proposed. By propagating standard deviations and correlations instead of the covariance in the unscented Kalman filter (UKF), the ... -
Towards a circular phosphorus economy in Norway - Strategies for integrating agriculture and aquaculture at multiple scales
(Research report, 2023)Phosphorus is a building block for all life and therefore plays an essential role in food production. Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer, ... -
Local statistics of immiscible and incompressible two-phase flow in porous media
(Peer reviewed; Journal article, 2023)We consider immiscible and incompressible two-phase flow in porous media under steady-state conditions using a dynamic pore network model. We focus on the fluctuations in a Representative Elementary Area (REA), with the ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -
Use of H2 in Mn-Ferroalloy Production
(Chapter, 2023)The use of H2 as a reductant in the iron and steel industry is an obvious choice towards carbon neutrality. For pyrometallurgical processes like Mn and Si, H2 cannot be the only solution, as the stability of the oxides of ...
