An interfacial gas-enrichment strategy for mitigating hydrate adhesion and blockage
(Peer reviewed; Journal article, 2022)Unwanted gas hydrates blockage is a threat to the safety of oil-gas pipeline systems. Deploying passive anti-hydrate surfaces is a promising approach to circumventing the long-lasting hydrate problem, and a precise ... -
Interfacial leakage of elastomer seals at low temperatures
(Journal article; Peer reviewed, 2018)Interfacial leakage of air in hydrogenated nitrile butadiene rubber (HNBR) O-ring seals exposed to sub-ambient temperatures is studied. Flange-type fixtures with sealing surfaces produced by 3 different surface finish ... -
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 ... -

(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 ... -
Interfacial microstructure formation in A356/steel compound castings using metal coating
(Peer reviewed; Journal article, 2020)Compound castings between aluminum and steel have great potential for applications in the automotive industry. However, due to large differences in thermal and mechanical properties between steel and aluminum, and the ... -
Interfacial Microstructure Formation in Al7SiMg/Cu Compound Castings
(Peer reviewed; Journal article, 2020)Compound casting is an attractive approach to create multi-material components and thus reduce the overall weight, while maintaining both the functional and mechanical properties. In this work, Al7SiMg alloy/copper compound ... -
Interfacial properties of dissolved crude oil components in produced water
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:, Doctoral thesis, 2013)Produced water is a mixture of water trapped in underground formations and injection water that is brought to the surface along with oil or gas. In general, produced water is a mixture of dispersed oil in water (o/w), ... -
Interfacial properties pertinent to W/O and O/W emulsion systems prepared using polyaromatic compounds
(Journal article; Peer reviewed, 2019)Establishing interfacial science to understand molecular mechanisms of stabilizing water in heavy crude oil (W/O) emulsions is challenging due to non-transparent nature of crude oil even in diluted systems, as most of the ... -
Interfacial Study of Input Data in Dynamic Ice-Structure Interaction and Evaluation of Tactile Sensors Usability in Ice-Related Problems
(Master thesis, 2014)Tactile sensor recordings have been analyzed in time domain, frequency domain and visually to identify failure processes along a structural interface. Except for the pre-study to this thesis, there was not found anywhere ... -
