Redox transformations of Ru catalyst during NO oxidation at industrial nitric acid production conditions
(Peer reviewed; Journal article, 2023)Oxidation of nitric oxide is one of the main steps in the Ostwald process for industrial nitric acid production. This work summarises the use of - supported Ru catalyst to study the oxidation of NO to NO at ambient and 4 ... -
The Enhancing Effect of α–FeOOH on Ni Surfaces Toward Electrolytic Water Splitting
(Journal article; Peer reviewed, 2023)For decades Ni has been known as an electrocatalyst for the oxygen evolution reaction (OER); however, the crucial role that Fe plays in enhancing the electrocatalytic activity of Ni still requires deeper investigation and ... -
Shape of a frictional fluid finger
(Peer reviewed; Journal article, 2023)Frictional fluid dynamics describes the displacement patterns that arise when a confined mixture of liquid and grains are displaced by an immiscible fluid under pressures that are too small to cause drainage into single ... -
Control of Magnon Condensates
(Doctoral theses at NTNU;2024:63, Doctoral thesis, 2024)Spintronics is a technology driven field aimed at harnessing the electron spin for novel devices. This is in contrast to traditional electronics, where the electron charge is used as an information carrier. Advances in ... -

Simulation of potential and species distribution in a Li||Bi liquid metal battery using coupled meshes
(Journal article; Peer reviewed, 2023)In this work a 1D finite volume based model using coupled meshes is introduced to capture potential and species distribution throughout the discharge process in a lithium–bismuth liquid metal battery while neglecting ... -
A data-derived reference mixture representative of European wastewater treatment plant effluents to complement mixture assessment
(Journal article; Peer reviewed, 2023)Aquatic environments are polluted with a multitude of organic micropollutants, which challenges risk assessment due the complexity and diversity of pollutant mixtures. The recognition that certain source-specific background ... -
Deflecting Dendrites by Introducing Compressive Stress in Li7La3Zr2O12 Using Ion Implantation
(Peer reviewed; Journal article, 2023)Lithium dendrites belong to the key challenges of solid-state battery research. They are unavoidable due to the imperfect nature of surfaces containing defects of a critical size that can be filled by lithium until fracturing ... -
Functional characterization of a lytic polysaccharide monooxygenase from Schizophyllum commune that degrades non-crystalline substrates
(Journal article; Peer reviewed, 2023)Lytic polysaccharide monooxygenases (LPMOs) are mono-copper enzymes that use O2 or H2O2 to oxidatively cleave glycosidic bonds. LPMOs are prevalent in nature, and the functional variation among these enzymes is a topic of ... -
Spatial cumulant models enable spatially informed treatment strategies and analysis of local interactions in cancer systems
(Peer reviewed; Journal article, 2023)Theoretical and applied cancer studies that use individual-based models (IBMs) have been limited by the lack of a mathematical formulation that enables rigorous analysis of these models. However, spatial cumulant models ... -
Development of Solvent Degradation Models for Amine-Based CO2 Capture
(Doctoral theses at NTNU;2024:54, Doctoral thesis, 2024)Carbon capture and storage can be essential for achieving short-term emission reductions to reach climate goals and realizing the decarbonization of hard-to-abate sectors in the future. Aside from logistical and political ... -
Do oil droplets and chemical dispersants contribute to uptake of oil compounds and toxicity of crude oil dispersions in cold-water copepods?
(Journal article; Peer reviewed, 2023)Accidental crude oil spills to the marine environment cause dispersion of oil into the water column through the actions of breaking waves, a process that can be facilitated using chemical dispersants. Oil dispersions contain ... -
Steady-State Two-Phase Flow of Compressible and Incompressible Fluids in a Capillary Tube of Varying Radius
(Peer reviewed; Journal article, 2023)We study immiscible two-phase flow of a compressible and an incompressible fluid inside a capillary tube of varying radius under steady-state conditions. The incompressible fluid is Newtonian and the compressible fluid is ... -
