SEM/EDX, XPS, corrosion and surface roughness characterization of AISI 316L SS after electrochemical treatment in concentrated HNO3
(Journal article; Peer reviewed, 2015)In the paper there is described the AISI 316L stainless steel surface obtained after electrochemical treatment in concentrated HNO3. It was characterized by roughness parameters, corrosion protection behaviour and chemical ... -
High-current-density electropolishing (HDEP) of AISI 316L (EN 1.4404) stainless steel
(Journal article; Peer reviewed, 2015)The paper presents new XPS results of surface layers formed after electrochemical polishing of AISI 316L stainless steel at high current density (HDEP) of 1000 A/dm2 (EP1000) versus a standard electropolishing (EP50) process ... -
Fundamental formulae for wave-energy conversion
(Journal article; Peer reviewed, 2015)The time-average wave power that is absorbed, from an incident wave, by means of a wave energy conversion (WEC) unit, or by an array of WEC units--i.e. oscillating immersed bodies and/or OWCs--may be mathematically expressed ... -
Computed X-ray Tomography Study of Carbonate Precipitation in Large Portland Cement Pores
(Journal article; Peer reviewed, 2019)Cement degradation caused by CO2 exposure is an increasingly important environmental challenge that must be understood, for example, if former oil reservoirs are to be used for CO2 storage. When exposed to CO2-saturated ... -
Dispersionsrelasjonen til magnoner i ultratynne Co filmer grodd på Ir(111)
(Master thesis, 2019)I denne masteroppgaven har de magnetiske egenskapene til en 1.6 ML Co film, grodd på et Ir(111) substrat, blitt undersøkt ved hjelp av spin-polarisert elektron energitap spektroskopi (SPEELS). To magnon-eksitasjonstopper ... -
Cleaning methods and aluminium growth on yttrium iron garnet
(Master thesis, 2019)Å forstå tynn film vekst på yttrium jern granat(YIG) er eit vikitig steg å ta før ein kan studere magnon-elektronvekselvikning for å koble elektronikk og spinntronikk. Magnon-elektronvekselvirkning på eit metall-magnetiskisolator ... -
Modeling hemodynamic responses during virtual navigation in human 7T- fMRI
(Master thesis, 2019)Functional magnetic resonance imaging (fMRI) is one of the most widely used non-invasive neuroimaging technique in humans. fMRI measures neural activity indirectly in the form of the blood-oxygen-level-dependent (BOLD) ... -
Red versus blue light illumination in hexyl 5-aminolevulinate photodynamic therapy: the influence of light color and irradiance on the treatment outcome in vitro
(Journal article; Peer reviewed, 2014)Abstract. Hexyl 5-aminolevulinate (HAL) is a lipophilic derivative of 5-aminolevulinate, a key intermediate in biosynthesis of the photosensitizer protoporphyrin IX (PpIX). The photodynamic efficacy and cell death mode ... -
Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
(Journal article; Peer reviewed, 2014)We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ... -
Effective Lagrangians for quantum many-body systems
(Journal article; Peer reviewed, 2014)The low-energy and low-momentum dynamics of systems with a spontaneously broken continuous symmetry is dominated by the ensuing Nambu-Goldstone bosons. It can be conveniently encoded in a model-independent effective field ... -
Direct Determination of Chitosan–Mucin Interactions Using a Single-Molecule Strategy: Comparison to Alginate–Mucin Interactions
(Journal article; Peer reviewed, 2015)Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct ... -
Inverse magnetic catalysis and regularization in the quark-meson model
(Journal article; Peer reviewed, 2015)Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ... -
Atomic structures of precipitates in Al–Mg–Si alloys with small additions of other elements
(Journal article; Peer reviewed, 2018)In Al–Mg–Si alloys, additions of only a few weight percent of Mg and Si enable formation of hardening precipitates during heat treatment. The precipitation is complex and is influenced by chemical compositions and ... -
Cr/Fe ratio by XPS spectra of magnetoelectropolished AISI 316L SS fitted by Gaussian-Lorentzian shape lines
(Journal article; Peer reviewed, 2014)In the paper, the analyses of Fe2p3/2 and chromium Cr2p3/2 XPS spectra with fitting by symmetrical and asymmetrical line shapes, are presented. The calculations are performed on AISI 316L SS biomaterial after magnetoelec ... -
Masteroppgave - A Predictive Model for Biological Range Shift in Proton Therapy
(Master thesis, 2019)Protonterapi er en metode innenfor str˚alebehandling for kreft som har blitt tatt i bruk i mange land over hele verden i løpet av de siste ti˚arene. Et argument for ˚a bruke protonterapi er at protonene har en bedre ... -
Introduksjon til gravitasjonsbølger
(Master thesis, 2019)I denne oppgaven utleder vi Einsteins feltligninger fra Einstein-Hilbert actionen ved å bruke variasjonsprinsipper. Videre ser vi på svak-felt grensen av disse ligningene ved å benytte en lineær approksimasjon. Gjennom en ... -
Nanoscale Characterisation of Deformed Aluminium Alloys
(Doctoral theses at NTNU;2019:252, Doctoral thesis, 2019)Summary: Nanoscale Characterisation of Deformed Aluminium Alloys Abstract Understanding deformation of structures made from aluminium alloys is important for a range of industries. Aluminium producers must know ... -
Mueller matrix three-dimensional directional imaging of collagen fibers
(Journal article; Peer reviewed, 2014)A method for measuring three-dimensional (3-D) direction images of collagen fibers in biological tissue is presented. Images of the 3-D directions are derived from the measured transmission Mueller matrix images (MMIs), ... -
Three-loop HTLpt thermodynamics at finite temperature and chemical potential
(Journal article; Peer reviewed, 2014)We calculate the three-loop thermodynamic potential of QCD at finite temperature and chemical potential(s) using the hard-thermal-loop perturbation theory (HTLpt) reorganization of finite temperature and density QCD. The ... -
Exotic Vortex Structures in Diffusive Superconducting Systems
(Master thesis, 2019)Selv vanligvis ikke-superledende materialer kan oppføre seg superledende dersom de blir plassert inntil en superleder. Dette fenometet kalles the proximity effect på engelsk, og når to materialer plasseres inntil hverandre ...
