From Nickel Ore to Ni Nanoparin the Extraction Process: Properties and Application
(Journal article; Peer reviewed, 2023)Laterite nickel ore is a mineral rock, which contains iron–nickel oxide compounds. One processing technology proposed to treat the ore is the Caron process. In general, the Caron process combines pyrometallurgical and ... -
From Nucleation to Percolation: The Effect of System Size when Disorder and Stress Localization Compete
(Peer reviewed; Journal article, 2021)A phase diagram for a one-dimensional fiber bundle model is constructed with a continuous variation in two parameters guiding the dynamics of the model: strength of disorder and range of stress relaxation. When the range ... -
From Poly(glycerol itaconate) Gels to Novel Nonwoven Materials for Biomedical Applications
(Peer reviewed; Journal article, 2023)Electrospinning is a process that has attracted significant interest in recent years. It provides the opportunity to produce nanofibers that mimic the extracellular matrix. As a result, it is possible to use the nonwovens ... -
From Rock Scissor Paper to study and modeling of Chinese Five Elements: Evolutionary Game Theory
(Master thesis, 2013)In this thesis, we have developed a model to study the behavior of an extended version of evolutionary game "Rock-Scissor-Paper", that is "Five Elements". The origin of five elements are from "Chinese five elements" in ... -
From Svalbard to Siberia: Passerines breeding in the High Arctic also endure the Extreme cold of the Western Steppe
(Journal article; Peer reviewed, 2018)Few species are adapted to high latitudes, and many over-winter in milder climates with migrations involving extensive barrier crossings. By escaping extreme conditions for the majority of the year, physiological and ... -
From the Ocean to the Lab—Assessing Iron Limitation in Cyanobacteria: An Interface Paper
(Peer reviewed; Journal article, 2020)Iron is an essential, yet scarce, nutrient in marine environments. Phytoplankton, and especially cyanobacteria, have developed a wide range of mechanisms to acquire iron and maintain their iron-rich photosynthetic machinery. ... -
From-scratch development and improvement of a problem-based learning course: Nonlinear Model Predictive Control for Chemical and Biochemical Processes
(Journal article; Peer reviewed, 2022) -
Fryselagring av hepatopankreas fra taskekrabbe (Cancer pagurus): En studie på endring i fettsyresammensetning og innhold av frie fettsyrer, samt intravevsvariasjoner.
(Bachelor thesis, 2024)Fettsyresammensetning i en organisme bidrar til økosystemforståelse og gir innsikt i diett og habitat, samt hvilket trofisk nivå en art tilhører. I tillegg kan fettsyresammensetning være indikator for terrestrisk påvirkning, ... -
FSC hollow fibre membranes - Optimization of coating and drying procedures
(Master thesis, 2016)Composite hollow fibre membranes were prepared by coating PVAm and PDMS, on a PSf support. Bundles consisting of 100 fibres were placed in PVC tubes with diameter 0.6cm, which gave a packing density of 30,3%. The bundles ... -
Fuel oil desulfurization with dual functionalized imidazolium based ionic liquids
(Peer reviewed; Journal article, 2020)A series of 36 dual functionalized N-(poly)ethylen glycol N-allyl-/N-benzyl imidazolium and benzimidazolium ILs were synthesized for extractive desulfurization studies (EDS). The novel ILs were readily prepared from imidazole ... -
Full Waveform Inversion of Gas Hydrates: Application to estimate of hydrate saturation
(Master thesis, 2014)Through seismic acquisitions there have been discovered layers beneath the seabedthat consist of pores filled with gas hydrates (GH). These reservoirs are potentialenergy reserves and it is therefore desirable to get an ... -
A Full-Field Crystal Plasticity Study on the Bauschinger Effect Caused by Non-Shearable Particles and Voids in Aluminium Single Crystals
(Journal article; Peer reviewed, 2024)In the present work, the goal is to use two-scale simulations to be incorporated into the full-field open software DAMASK version 2.0.3 crystal plasticity framework, in relation to the Bauschinger effect caused by the ... -
Fully Polarizable QM/Fluctuating Charge Approach to Two-Photon Absorption of Aqueous Solutions
(Peer reviewed; Journal article, 2019)We present the extension of the quantum/classical polarizable fluctuating charge model to the calculation of single residues of quadratic response functions, as required for the computational modeling of two-photon absorption ... -
Fully resolved strain field of the β’’ precipitate calculated by density functional theory
(Peer reviewed; Journal article, 2020)The β′′ precipitate is the main hardening phase in age hardenable Al-Mg-Si alloys, and it is therefore of major scientific and industrial importance. A full model of the β′′ precipitate cross-section embedded in an aluminium ... -
Fume Formation and Measurements in the Metal-Production Industry
(Doctoral theses at NTNU;2022:14, Doctoral thesis, 2021)Airborne Particulate Matter (PM) is considered to be a major concern for both occupational health and the environment, and in the metal production industry, the level of such particles in the air can be considerable. This ... -
Fume Formation from Oxidation of Liquid SiMn Alloy
(Journal article; Peer reviewed, 2017)Thermally generated fumes from the production of manganese ferroalloys are mostly composed of metallic oxides generated due to reaction between high-temperature molten metal and ambient oxygen in the air. In the current ... -
Fuming during processing of FeSi alloys
(Master thesis, 2021)Støving er ei stor utfordring for metallproduksjonsindustrien. Støv går inn i naturen som forurensing, og luftveiene til verksarbeidere, hvor de bidrar til luftveissykdommer og kreft. Derfor er det veldig viktig å kontrollere ... -
