First-order superconducting phase transition in a chiral p+ip system
(Peer reviewed; Journal article, 2021)We use large-scale Monte Carlo computations to study the phase transitions between a two-component chiral p -wave superconductor and normal state in zero external magnetic field. We find a first-order phase transition from ... -
First-principles study of tensile and shear strength of an Fe2Al5//Fe interface
(Peer reviewed; Journal article, 2021)The interfacial strengths of a low misfit Fe2Al5//Fe interface structure found at aluminum-steel joints has been studied using density functional theory. An interface between Fe and Fe2Al5 was selected based on a criteria ... -
First-principles study of tensile and shear strength of Fe-Al and α-AlFeSi intermetallic compound interfaces
(Peer reviewed; Journal article, 2021)First-principles virtual tensile and shear strength calculations have been performed on the Fe2Al5// Fe4Al13 and -AlFeSi// Fe4Al13 interfaces. The Fast Inertial Relaxation Engine (FIRE) algorithm is used for optimizing ... -

Flare Duty Cycle of Gamma-Ray Blazars and Implications for High-energy Neutrino Emission
(Journal article; Peer reviewed, 2023) -
Flat-top supercontinuum and tunable femtosecond fiber laser sources at 1.9-2.5 μm
(Journal article; Peer reviewed, 2016)We report the high-energy flat-top supercontinuum covering the midinfrared wavelength range of 1.9-2.5 μm as well as electronically tunable femtosecond pulses between 1.98 and 2.22 μm directly from the thulium-doped fiber ... -
Flavor Oscillations of High-Energy Neutrinos
(Master thesis, 2016)In this thesis, we study neutrino oscillations in vacuum and in the presence of a Dark Matter halo in the Milky Way. For that purpose, first describe the particle physics of neutrinos through an historical introduction. ... -
Flow-Area Relations in Immiscible Two-Phase Flow in Porous Media
(Journal article; Peer reviewed, 2020)We present a theoretical framework for immiscible incompressible two-phase flow in homogeneous porous media that connects the distribution of local fluid velocities to the average seepage velocities. By dividing the pore ... -
Fluid flow through 3D-printed particle beds: a new technique for understanding, validating, and improving predictability of permeability from empirical equations
(Peer reviewed; Journal article, 2020)The application of 3D technology for fabrication of artificial porous media samples improves porous media flow studies. The geometrical characteristics of a porous media pore channel: the channel shape, size, porosity, ... -
Fluid Meniscus Algorithms for Dynamic Pore-Network Modeling of Immiscible Two-Phase Flow in Porous Media
(Peer reviewed; Journal article, 2021)We present in detail a set of algorithms for a dynamic pore-network model of immiscible two-phase flow in porous media to carry out fluid displacements in pores. The algorithms are universal for regular and irregular pore ... -
Fluorescent Ligands for Detection of Transthyretin Amyloid - Photophysics and Cytotoxicity on Astrocytes
(Master thesis, 2021)Når proteiner feilfoldes og danner uoppløselige avleiringer får man amyloidfibriller. Sykdommer som forårsakes av disse proteinaggregatene kalles for amyloidose. Når transportproteinet transthyretin (TTR) danner amyloidfibriller ... -
Fluorescent Nanocomposites: Hollow Silica Microspheres with Embedded Carbon Dots
(Journal article; Peer reviewed, 2021)Intrinsically fluorescent carbon dots may form the basis for a safer and more accurate sensor technology for digital counting in bioanalytical assays. This work presents a simple and inexpensive synthesis method for producing ... -
Fluorohectorite as a CO2 adsorbent: a DFT and DFTB study.
(Master thesis, 2020)I denne oppgaven gjøres beregninger med tetthetsfunksjonalteori (DFT) og tetthetsfunksjonalteori tight binding (DFTB) på leirematerialet fluorhektoritt for å finne hvilke kationer som passer best for interkalasjon av CO2. ... -
Flux Optimisation of the Cold Neutron Source in the JEEP II Reactor
(Master thesis, 2019)The purpose of this thesis is to describe the optimisation of the cold moderator setup in the JEEP II research reactor. This includes the development of a MCNP model of the tangential beam channel of the JEEP II, combining ... -
Flytende tak i en konsertsal
(Master thesis, 2013)I denne masteroppgaven har det blitt sett på hva som skjer med de vanlige romakustiske parametrene ved å ha et fritthengende flytende tak med åpning mot sideveggene i en konsertsal. Koplingen mellom rommet over og under ... -
Focused ultrasound and microbubble treatment increases delivery of transferrin receptor-targeting liposomes to the brain
(Peer reviewed; Journal article, 2021)The blood-brain barrier (BBB) is a major obstacle to treating several brain disorders. Focused ultrasound (FUS) in combination with intravascular microbubbles increases BBB permeability by opening tight junctions, creating ... -
Formation models for cosmic ray antinuclei
(Peer reviewed; Journal article, 2022)The expected low background of light antinuclei, such as antideuteron and antihelium-3, makes them ideal detection channels for exotic physics, such as dark matter annihilations. At the same time, their small binding ... -
