Towards greener wind power: Nanodiamond-treated flax fiber composites outperform standard glass fiber composites in impact fatigue tests
(Journal article; Peer reviewed, 2024)Wind energy is facing two major problems, recyclability of wind turbine blades, primarily made from fiberglass, and rain erosion on the blade’s leading edges. Here, we show that flax fiber reinforced epoxy composites have ... -
Failsafe layer for wind turbine blades: Erosion protection of glass fiber composite through nanodiamond-treated flax composite top layer
(Journal article; Peer reviewed, 2024)Wind turbine blades are mainly made from E-glass fiber (GF) epoxy composites, because of their good ratio of strength to weight and costs. With the increase in blade length and tip speed, the problem of leading edge erosion ... -
Nanodiamond-treated Flax: Reducing Erosion on Wind Turbine Blades
(Doctoral thesis, 2024-10-03)Arbeidet som presenteres i denne oppgaven undersøker nye materialer for vindturbinblader som er mer erosjonsbestandige enn de vanlig brukte glassfiber-forsterkede komposittene (GFRCs). Med den pågående økningen i størrelsen ... -
Recent advances in emerging integrated anticorrosion and antifouling nanomaterial-based coating solutions
(Journal article; Peer reviewed, 2024)The rapid progress in the marine industry has resulted in notable challenges related to biofouling and surface corrosion on underwater infrastructure. Conventional coating techniques prioritise individual protective ... -
Impact of gas type on microfluidic drainage experiments and pore network modeling relevant for underground hydrogen storage
(Journal article; Peer reviewed, 2024)Underground hydrogen storage (UHS) in geological reservoirs is proposed as a technically feasible solution to balance mismatch between supply and demand in emerging markets. However, unique hydrogen properties and coupled ... -
Experimentally assessing the uncertainty of forecasts of geological carbon storage
(Journal article; Peer reviewed, 2024)Geological storage of carbon dioxide is a cornerstone in almost every realistic emissions reduction scenario outlined by the Intergovernmental Panel on Climate Change. Our ability to accurately forecast storage efficacy ... -
Atomic resolution transmission electron microscopy visualisation of channel occupancy in beryl in different crystallographic directions
(Journal article; Peer reviewed, 2024)The causes of colour in beryl have been a research topic for decades. For some varieties, such as emerald (green, coloured by Cr3+ and/or V3+), the main cause of colour is substitutions by metal atoms within the framework. ... -

Physical Variability in Meter-Scale Laboratory CO2 Injections in Faulted Geometries
(Journal article; Peer reviewed, 2024)Carbon, capture, and storage (CCS) is an important bridging technology to combat climate change in the transition toward net-zero. The FluidFlower concept has been developed to visualize and study CO2 flow and storage ... -
Pixelwise immersion factor calibration for underwater hyperspectral imaging instruments
(Journal article; Peer reviewed, 2024)In situ spectral reflectance initially captured at high spatial resolution with underwater hyperspectral imaging (UHI) is effective for classification and quantification in oceanic biogeochemical studies; however, the ... -
A Pore-Level Study of Dense-Phase CO2 Foam Stability in the Presence of Oil
(Journal article; Peer reviewed, 2024)The ability of foam to reduce CO2 mobility in CO2 sequestration and CO2 enhanced oil recovery processes relies on maintaining foam stability in the reservoir. Foams can destabilize in the presence of oil due to mechanisms ... -
Pore-level Dense Phase CO2 Foam Dynamics during CO2 EOR and CO2 Storage
(Doctoral thesis, 2024-09-26)Rask befolkningsvekst, økende velstand og økonomisk ekspansjon bidro til at behovet for energi økte med 1.3% i 2022. Det økende energibehovet kan sees på som en trussel ettersom energiproduksjon representerer tre fjerdedeler ... -
On the strength of E and F region irregularities for GNSS scintillation in the dayside polar ionosphere
(Journal article; Peer reviewed, 2024)We present results of the study conducted to quantify the relative contribution of different ionospheric regions to phase scintillation in Global Navigation Satellite Systems (GNSS) at the dayside high latitude ionosphere. ... -
How Do Substorms Influence Hemispheric Asymmetries in Equivalent Currents?
(Journal article; Peer reviewed, 2024)Ionospheric dynamics exhibits a distinct hemispheric asymmetry, influenced primarily by the Interplanetary Magnetic Field (IMF) By component, dipole tilt, or a combination of both. Previous studies have indicated a reduction ... -
Fuzzy-Vocabulary-Based Detection and Explanation of Anomalies
(Journal article; Peer reviewed, 2023)Fuzzy partitions associated with linguistic variables are particularly useful to provide users with a description of the data. However, designing a fuzzy vocabulary that makes it possible to linguistically describe the ... -
A smart ocean observation system for reliable real-time measurements
(Chapter, 2023)This paper presents a research and innovation centre for a smart ocean observation system. The main goal of the centre, SFI Smart Ocean, is to enable sustainable ocean management through real-time measurements from autonomous ... -
Exploring the Predictability of the High-Energy Tail of MEE Precipitation Based on Solar Wind Properties
(Journal article; Peer reviewed, 2023)Medium Energy Electron (MEE) precipitation (≳30 keV) ionizes the mesosphere and initiates chemical reactions, which ultimately can reduce mesospheric and stratospheric ozone. Currently, there are considerable differences ... -
