Observation of Electric-Field-Induced Structural Dislocations in a Ferroelectric Oxide
(Peer reviewed; Journal article, 2021)Dislocations are 1D topological defects with emergent electronic properties. Their low dimensionality and unique properties make them excellent candidates for innovative device concepts, ranging from dislocation-based ... -
Observations of rising methane bubbles in Trondheimsfjord and its implications to gas dissolution
(Journal article; Peer reviewed, 2019-02-13)Gas dissolution reduces the release of methane to the atmosphere from subsea sources. Being able to predict and assess the methane flux to the atmosphere requires knowledge on gas dissolution and mass transfer. This can ... -

Occurrence, characterisation and fate of (nano)particulate Ti and Ag in two Norwegian wastewater treatment plants
(Journal article; Peer reviewed, 2018-09-15)Due to their widespread application in consumer products, elemental titanium (e.g., titanium dioxide, TiO2) and silver (Ag), also in nanoparticulate form, are increasingly released from households and industrial facilities ... -
Offset dependence of overburden time-shifts from ultrasonic data
(Peer reviewed; Journal article, 2020)Depletion or injection into a reservoir implies stress changes and strains in the reservoir and its surroundings. This may lead to measurable time-shifts for seismic waves propagating in the subsurface. To better understand ... -
Offshore Wind: Employment and value creation of EPCI exports in Norway
(Peer reviewed; Journal article, 2021)The objective of this study is to investigate the value creation potential and the employment effects for the offshore wind engineering, procurement, construction and installation (EPCI) sector in Norway up to 2030 considering ... -
On capital utilization in the hydrogen economy: The quest to minimize idle capacity in renewables-rich energy systems
(Peer reviewed; Journal article, 2020)The hydrogen economy is currently experiencing a surge in attention, partly due to the possibility of absorbing variable renewable energy (VRE) production peaks through electrolysis. A fundamental challenge with this ... -
On Common Research Needs for the Next Generation of Floating Support Structures
(Chapter; Peer reviewed, 2022)The world is facing several industrial and societal challenges, such as providing enough renewable energy and enough safe and healthy food as formulated in the United Nations sustainable development goals. Using floating ... -
On intermetallic phases formed during interdiffusion between aluminium alloys and stainless steel
(Peer reviewed; Journal article, 2022)One of the major challenges in welding of aluminium (Al) alloys and steels is the growth of brittle intermetallic phases, which depends on the thermomechanical processing history and the alloying elements. This work focuses ... -
On pragmatism in industrial modeling
(SINTEF Proceedings;1, Chapter, 2015)Many natural or industrial processes are of extreme complexity, and where the time- and length scales range from an atomistic level to years and kilometers. Often the processes or phenomena consist of multiple sub processes ... -
On pragmatism in industrial modeling. Part III: Application to operational drilling
(SINTEF Proceedings;2, Chapter, 2017)In this paper, we will apply the concepts of pragmatic industrial modelling to the development of a real time drilling support tool. We develop requirements to such a modelling tool, regarding both input and output, model ... -
On scenario construction for stochastic shortest path problems in real road networks
(Peer reviewed; Journal article, 2021)Stochastic shortest path (SSP) computations are often performed under very strict time constraints, so computational efficiency is critical. A major determinant for the CPU time is the number of scenarios used. We demonstrate ... -
On the Atomic Structure of the β′′ Precipitate by Density Functional Theory
(Peer reviewed; Journal article, 2023)The substitution of elements into the precipitate in the 6xxx-series of aluminium alloys is an interface sensitive problem. The strain caused by the misfit between the precipitate and the matrix interacts with the size ... -
On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record
(Journal article; Peer reviewed, 2019)Microaerophilic Fe(II)‐oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations. Extracellular Fe stalks ... -
On the choice of closure complexity in anisotropic drag closures for filtered Two Fluid Models
(Journal article; Peer reviewed, 2019)Filtered Two Fluid Models (fTFMs) aim to enable accurate industrial-scale simulations of fluidized beds by means of closures accounting for the effects of bubbles and clusters. The present study aims to improve anisotropic ... -
On the Direct Reduction Phenomena of Bauxite Ore Using H2 Gas in a Fixed Bed Reactor
(Peer reviewed; Journal article, 2020)The Bayer Process is the dominant industrial method to produce alumina from bauxite ore. Due to the generation of large amounts of Bauxite Residue (red mud), an alternative method, called the Pedersen Process, is of our ... -
On the Evolution of Stress and Microstructure in Radio Frequency-Sputtered Lead-Free (Ba,Ca)(Zr,Ti)O3 Thin Films
(Peer reviewed; Journal article, 2024)Thin-film piezoelectrics are widely investigated for actuators and energy harvesters, but there are few alternatives to toxic lead zirconate titanate. Biocompatible Ca- and Zr-modified BaTiO3 (BCZT) is one of the most ... -
On the Feasibility of Using Low-Melting Bath to Accommodate Inert Anodes in Aluminium Electrolysis Cells
(Peer reviewed; Journal article, 2021)Inert anodes for aluminium production can be made of ceramics, metals, or a mixture of those (cermets). Regardless of the type of anode, the surface will be an oxide. With high enough anode potential, the surface oxide ... -
