(Peer reviewed; Journal article, 2021)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ... -
Interfacial Boundary between Carbon Anodes and Molten Salt Electrolyte
(Journal article, 2016)The properties of calcined petroleum cokes (CPC), used in the anodes in the Hall-Héroult process, are important for the electrochemical behaviour of the anodes. CPCs from different sources vary not only in impurity level ... -
Interfacial characterisation of dispersed components in produced water
(Master thesis, 2012)While a number of studies have investigated the processes responsible for the decay of the interfacial tension between crude oil and water with time, there is a great need for an improved understanding of the mechanisms ... -
Interfacial Characterisation of Gas-Liquid Interfaces Related to Gas Flotation in Offshore Produced Water Treatment - Dynamic Adsorption of Heteroatoms
(Master thesis, 2014)Produced water is the largest waste stream produced in the recovery of oil and gas. The processing of produced water occurs in several stages including gas flotation. Gas flotation is separation by gravity and the effectiveness ... -
Interfacial control of vortex-limited critical current in type-II superconductor films
(Master thesis, 2021)Ginzburg-Landau (GL)-teorien for superledning i kombinasjon med spinn-bane-kobling er brukt til å beregne kritisk strøm i type-II superledende tynne filmer med Rashba spinn-bane-kobling. Formalismen som er benyttet her er ... -
Interfacial dilation rheology properties of films formed at the oil/water interface by reaction between acid and calcium ion
(Master thesis, 2017)Interaction between ARN and Asphaltenes and consequences for the solubility of ARN in oil -
Interfacial Dilational Rheology of Molecular Films in DC Electric Fields
(Journal article; Peer reviewed, 2022)We present a novel technique to measure the interfacial dilational rheology of a molecular film adsorbed at a water–oil interface in a direct-current (dc) electric field. A film of a highly polar subfraction of asphaltenes ... -
Interfacial dilational rheology properties of films formed at the oil/water interface by reaction between tetrameric acid and calcium ion
(Journal article; Peer reviewed, 2017)This article aims to determine the applicability of interfacial dilational rheology to study the formation of viscoelastic film at the oil/water interface by reaction between tetrameric acids ARN and calcium ions, and to ... -
Interfacial magnon-mediated superconductivity in twisted bilayer graphene
(Journal article; Peer reviewed, 2024)The interfacial coupling between electrons and magnons in adjacent layers can mediate an attractive electron–electron interaction and induce superconductivity. We consider magic-angle twisted bilayer graphene sandwiched ... -
Interfacial mass transfer and bubble hydrodynamics in bubble columns
(Doctoral theses at NTNU;2023:420, Doctoral thesis, 2023)The interaction between gas–liquid or gas–liquid–solid phases exhibit complexity which for years have led researchers to study the intrinsic mechanisms involved. One important branch within multi-phase flow is the interfacial ... -
Interfacial mass transfer limitations in the Fischer-Tropsch synthesis operated in a slurry bubble column at industrial conditions
(Journal article; Peer reviewed, 2018)At high catalyst volume fractions the Fischer-Tropsch synthesis (FTS) operated in a slurry bubble column (SBC) is driven into the mass transfer limited regime. This study utilized literature models for the gas-liquid mass ... -
