High-Temperature Reactive Wetting of Natural Quartz by Liquid Magnesium
(Journal article; Peer reviewed, 2024)High-temperature wetting of natural, high-purity quartz (SiO2) and liquid magnesium (Mg) was investigated at temperatures between 973 and 1273 K. Sessile drop experiments using the capillary purification (CP) procedure ... -
Simple and Robust Formulations of the Unscented Kalman Filter and Model Predictive Control
(Doctoral theses at NTNU;2024:93, Doctoral thesis, 2024)This thesis focuses mainly on state estimation by the Unscented Kalman filter (UKF), and partly on robust nonlinear model predictive control (RNMPC). Our aim is to refine or develop algorithms which are simple to implement, ... -
The effects of freezing and thawing on Alaria esculenta
(Journal article; Peer reviewed, 2024)Seaweeds must be stabilised shortly after harvesting to avoid rapid deterioration. To handle large amounts harvested during a short period, freezing and frozen storage until utilisation or further processing is one of the ... -
Metabolic engineering of industrially relevant strains for the production of riboflavin from sustainable feedstocks
(Doctoral theses at NTNU;2024:95, Doctoral thesis, 2024)There is an increasing demand for agricultural land and other resources necessary to feed an expanding world population. This has led to a growing interest in using sustainable feedstocks to produce value-added compounds ... -
Oxidative degradation of triethylene glycol
(Journal article; Peer reviewed, 2024)Triethylene glycol (TEG) is unstable in the presence of oxygen and at high temperatures, though the degradation mechanisms occurring are not properly understood. In attempting to close some of the knowledge gaps, ... -
The effect of salmon protein hydrolysate on palatability for Atlantic salmon smolts
(Master thesis, 2024)Krav om bedre fiskevelferd og mer bærekraftig akvakultur gjør det nødvendig å finne nye og bedre fôrressurser. Når man vurderer nye ingredienser til fôr, kan valg av strategi ha stor innvirkning på tolkningen av kvaliteten ... -
Krabbespredning i nord - Toktrapport 2023200030
(Toktrapport;, Research report, 2024)Taskekrabbe (Cancer pagurus) har spredd seg nordover i Troms, men utbredelse og bestandstetthet i Nord-Norge har så langt ikke blitt kartlagt. Det er ukjent om taskekrabbens utbredelsesområder overlapper med kongekrabbens ... -
FP-MAP: an extensive library of fingerprint-based molecular activity prediction tools
(Peer reviewed; Journal article, 2023)Discovering new drugs for disease treatment is challenging, requiring a multidisciplinary effort as well as time, and resources. With a view to improving hit discovery and lead compound identification, machine learning ... -
Experimental and Numerical Results of a Non-DLE Aeroderivative GT Combustion System Burning Methane-Ammonia Blends at Intermediate Pressures
(Chapter, 2023)Ammonia is considered as a practical hydrogen carrier, as it can be stored in liquid form at moderate pressures and temperatures and is commonly produced and transported today. Ammonia could be used directly as a Gas Turbine ... -
Improved Synthetic Methodology, Substrate Scope and X-ray Crystal Structure for N, N’-disubstituted Guanidines
(Peer reviewed; Journal article, 2024)Guanidine is a privileged scaffold in drug discovery. Herein we report our investigations into the acid promoted amination of pyrimidine-bearing cyanamide to produce N, N’-disubstituted guanidines. Hydrochloric acid was ... -
Shaping the Structure and Properties of TiO2-ZnO Oxide Coatings Produced by Plasma Electrolytic Oxidation on Titanium Substrate
(Peer reviewed; Journal article, 2023)The paper presents the results of preliminary research on the possibility of synthesizing ZnO-TiO2 mixed coatings by plasma electrochemical oxidation (PEO). The aim of the work was to synthesize TiO2-ZnO mixed coatings on ... -
Design of multi-luminescent silica-based nanoparticles for the detection of liquid organic compounds
(Journal article; Peer reviewed, 2024)Tracer testing in reservoir formations is utilised to determine residual oil saturation as part of optimum hydrocarbon production. Here, we present a novel detection method of liquid organic compounds by monodisperse SiO2 ... -
Thermodynamically consistent modeling of gas flow and adsorption in porous media
(Journal article; Peer reviewed, 2024)In modeling of gas flow through porous media width adsorption, the thermodynamic properties of the adsorbed phase are usually approximated by those of the bulk liquid. Using non-isothermal, gaseous transport of moist air ... -
Expanding the coverage of regulons from high-confidence prior knowledge for accurate estimation of transcription factor activities
(Peer reviewed; Journal article, 2023)Gene regulation plays a critical role in the cellular processes that underlie human health and disease. The regulatory relationship between transcription factors (TFs), key regulators of gene expression, and their target ... -
Tracing the footprints of Arctic pollution: Spatial variations in toxic and essential elements in Svalbard reindeer (Rangifer tarandus platyrhynchus) faeces
