Walker Breakdown in Magnon-Induced Ferromagnetic Domain Wall Motion
(Master thesis, 2015)We derive for the first time the collective coordinate equations for magnon-driven domain wall motion in ferromagnets from the Landau-Lifshitz-Gilbert equation. By performing a consistent calculation to second order we are ... -
Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
(Journal article; Peer reviewed, 2014)One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ... -
Water adsorption on surfaces of calcium aluminosilicate crystal phase of stone wool: a DFT study
(Journal article; Peer reviewed, 2024)Water adsorption on surfaces of calcium aluminosilicate crystal phase of stone wool: a DFT study -
Water as a monomer: synthesis of an aliphatic polyethersulfone from divinyl sulfone and water
(Peer reviewed; Journal article, 2022)Using water as a monomer in polymerization reactions presents a unique and exquisite strategy towards more sustainable chemistry. Herein, the feasibility thereof is demonstrated by the introduction of the oxa-Michael ... -
Water as key to activity and selectivity in Co Fischer-Tropsch synthesis: γ-alumina based structure-performance relationships
(Journal article; Peer reviewed, 2018)Thirteen γ-alumina supports with different pore sizes and pore size distributions have been impregnated with cobalt and rhenium. The catalysts were tested for Fischer-Tropsch synthesis (FTS) under dry and enhanced water ... -
The water assisted vinylene mechanism for cobalt Fischer-Tropsch synthesis assessed by multi-catalyst modelling of kinetics and deactivation
(Peer reviewed; Journal article, 2022)The paper describes development of a mechanism and a consistent rate expression for Fischer-Tropsch (FT) synthesis over cobalt-based catalysts. The developed mechanism relies on a two-step hydrogen assisted activation of ... -
Water education, ocean literacy and arts integration. A literature review in an interdisciplinary team
(Journal article; Peer reviewed, 2023)The article is part of the special issue Vol. 12 No. 2 (2023): Aesthetics and Ethics: Arts Education as a Catalyst for Sustainable Development https://journals.oslomet.no/index.php/ar/issue/view/497 -
Water holding properties of Atlantic salmon
(Peer reviewed; Journal article, 2021)With global seafood production increasing to feed the rising population, there is a need to produce fish and fishery products of high quality and freshness. Water holding properties, including drip loss (DL) and water ... -
A Water Model Study of Alumina Feeding and Dispersion
(Journal article; Peer reviewed, 2022) -
Water quality in closed-containment aquaculture systems (CCS) for Atlantic salmon post-smolt - Non-target screening of organic substances using UPLC-MS/MS
(Master thesis, 2018)Organic substances may be released in a recirculating aquaculture system (RAS) from a variety of sources such as fish, feed, and bacteria among other. Due to continuous re-use of the water, compounds can potentially ... -
Water treatment as an approach to increase microbial control in the culture of cold water marine larvae
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:231, Doctoral thesis, 2011) -
Water waves with compactly supported vorticity: A functional-analytic approach to bifurcation theory and the mathematical theory of traveling water waves
(Master thesis, 2014)We study the mathematical theory of water waves. Local bifurcation theory is also discussed, including the Crandall-Rabinowitz theorem; an abstract theorem used to establish the presence of bifurcation points in the zero ... -
Water-lean solvents for biogas upgrading
(Doctoral theses at NTNU;2020:298, Doctoral thesis, 2020)Biogas upgrading consists in the removal of CO2 from biogas, a process which produces a highly purified biomethane stream. As such, biogas upgrading has a double positive impact when considering climate change mitigation ... -
Waterborne chitosan-epoxysilane hybrid pretreatments for corrosion protection of zinc
(Journal article; Peer reviewed, 2016)Biopolymer-based systems are extensively studied as green alternatives for traditional polymer coatings, e.g., in corrosion protection. Chitosan–epoxysilane hybrid films are presented in this work as a chitosan-based ... -
Water–Gas Shift Activity of Pt Catalysts Prepared by Different Methods
(Peer reviewed; Journal article, 2020)Platinum supported on ceria and zirconia was prepared through different preparation methods: Coprecipitation (CP), spray drying (SD), and flame spray pyrolysis (FSP). The catalysts were characterized by XRD, TPR, N2 ... -
Watt-level Kerr-Lens Mode-Locked Cr:ZnS Laser at 2.4 μm
(Chapter, 2013)Power scaling of Kerr-lens mode-locked Cr:ZnS femtosecond oscillator allows reaching 1 W output power and pulse energies over 8 nJ. Soliton and chirped-pulse regimes result in 68 fs and 0.8-2 ps pulses, respectively. -
Wave scattering and transmission from penetrable self-affine surfaces
(Master thesis, 2009) -
Wave scattering theory applied to inversion and design
(Doctoral theses at NTNU;2018:310, Doctoral thesis, 2018)The scattering of waves from objects can be used as a tool for both characterization and manipulation. The way waves interact and scatter from objects can give us information about their structure and composition. Additionally, ...
