Acid preservation of cultivated brown algae Saccharina latissima and Alaria esculenta and characterization of extracted alginate and cellulose
(Peer reviewed; Journal article, 2023)Cultivated brown algae represent an important potential source of carbohydrate polymers for packaging and other biobased materials. However, their exploitation is currently limited by a short harvest season and a lack of ... -
Enhanced path sampling using subtrajectory Monte Carlo moves
(Journal article, 2023)Path sampling allows the study of rare events, such as chemical reactions, nucleation, and protein folding, via a Monte Carlo (MC) exploration in path space. Instead of configuration points, this method samples short ... -
How far can we stretch the timescale with RETIS?
(Peer reviewed; Journal article, 2023)Molecular dynamics (MD) and Monte Carlo (MC) have long coexisted as two main independent branches of molecular simulation. In the late eighties, however, algorithms based on the combination of both were created such as ... -
Analysis of nitro- and oxy-PAH emissions from a pilot scale silicon process with flue gas recirculation
(Peer reviewed; Journal article, 2023) -
Path sampling with memory reduction and replica exchange to reach long permeation timescales
(Journal article, 2023)Assessing kinetics in biological processes with molecular dynamics simulations remains a computational and conceptual challenge, given the large time and length scales involved. For kinetic transport of biochemical compounds ... -
Predicting Silica Deposition from Superheated, Pressurized Steam Using Numerical Modeling of Nucleation, Agglomeration and Deposition
(Peer reviewed; Journal article, 2023)A model that can be used to quantify silica deposition from superheated depressurized steam is developed. Classical nucleation theory, agglomeration and deposition onto a wall are combined in a numerical model that calculates ... -
Quality Changes of Cultivated Saccharina latissima as Influenced by Preservation Method During Short Term Storage
(Journal article; Peer reviewed, 2023)Post-harvest changes in the quality of cut and whole S. latissima upon 23 days storage with or without acidification at different temperatures were studied by bacterial counts, amino acids composition, and 1H-NMR profiling ... -
Urban stormwater capture for water supply: look out for persistent, mobile and toxic substances
(Journal article; Peer reviewed, 2023)Urban stormwater was traditionally managed for flood control and property protection. But this view is changing as urban stormwater is increasingly recognized as an underused water resource. As cities implement stormwater ... -
Teaching In Student-Centred Active Learning Spaces: How Relational, Pedagogical, Spatial, And Technological Aspects Intertwine And Affect The Learning Environment
(Chapter, 2023)Higher educational institutions internationally have shown a growing interest in developing learning spaces that support student-centred learning approaches. For engineering education, this development aligns well with an ... -
Investigations into Lytic Polysaccharide Monooxygenase functionalities using NMR
(Doctoral theses at NTNU;2024:25, Doctoral thesis, 2024)English summary Lytic Polysaccharide Monooxygenases (LPMOs) are enigmatic enzymes that oxidatively depolymerize crystalline polysaccharides like cellulose and chitin. Following their discovery in 2010, LPMOs have gained ... -
Advancing Methods for Sampling and Analysis of Microplastics in the Marine Environment
(Doctoral theses at NTNU;2024:24, Doctoral thesis, 2024)Plastic pollution is one of many growing anthropogenic stressors in the marine environment, and its proliferation and effects are not fully understood. Research reporting abundance of plastic debris in the environment is ... -
Multiscale X-ray tomography for shale microstructure and mechanical behaviour
(Doctoral theses at NTNU;2024:39, Doctoral thesis, 2024)Studying shales and other sedimentary rock systems is important to provide a fundamental understanding of their microstructural properties, including the mechanical response and the permeability of liquids and gases. ... -
Investigation of the structural and immunomodulatory properties of alkali-soluble β-glucans from Pleurotus eryngii fruiting bodies
(Peer reviewed; Journal article, 2023)Fungal β-glucans have received a lot of interest due to their proinflammatory activity towards cells of the innate immune system. Although commonly described as (1➔3)-β-glucans with varying degree of (1➔6)-branching, the ... -
Performance of activated stainless steel and nickel-based anodes in alkaline water electrolyser
(Peer reviewed; Journal article, 2023)Four different alloys including SS316, SS304, Inconel718 and Incoloy800 are activated by electro-oxidation at +1.70 V vs. RHE in 7.5 M KOH for 18 h. Their OER activity are evaluated ex-situ using linear sweep voltammetry ... -
ID22 - the high-resolution powder-diffraction beamline at ESRF
(Journal article; Peer reviewed, 2023)Following Phase 2 of the upgrade of the ESRF in which the storage ring was replaced by a new low-emittance ring along with many other facility upgrades, the status of ID22, the high-resolution powder-diffraction beamline, ... -
Effects of gadolinium (Gd) and a Gd-based contrast agent (GBCA) on early life stages of zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)Gadolinium (Gd) is one of the rare earth elements (REY) and is widely used in magnetic resonance imaging (MRI) contrast agents. Anthropogenic Gd enrichment has frequently been found in wastewater treatment plant effluents ... -
Recommendations for quantitative uncertainty consideration in ecology and evolution
(Peer reviewed; Journal article, 2023)Ecological and evolutionary studies are currently failing to achieve complete and consistent reporting of model-related uncertainty. We identify three key barriers – a focus on parameter-related uncertainty, obscure ... -
Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2023)The microbiota of recirculating aquaculture systems (RAS) is of major importance for optimal fish health. However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
The role of seasonal migration in spatial population synchrony
(Peer reviewed; Journal article, 2023)Spatially synchronized population dynamics are common in nature, and understanding their causes is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared ... -
Effects of Compaction and Thermal Pre‑treatments on Generation of Dross and Off‑Gases in Aluminium Recycling
(Peer reviewed; Journal article, 2023)Organic coatings are a challenge for aluminium packaging recycling since they tend to increase the re-melting metal losses. A solution is de-coating the scrap via a thermal pre-treatment to burn-off the organics before ...
