Water Vapour Promotes CO2 Transport in Poly(ionic liquid)/Ionic Liquid-Based Thin-Film Composite Membranes Containing Zinc Salt for Flue Gas Treatment
(Peer reviewed; Journal article, 2020)A poly(ionic-liquid) (PIL) matrix can be altered by incorporating additives that will disrupt the polymer chain packing, such as an ionic liquid (IL) and inorganic salts to boost their exploitation as materials for membrane ... -
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 ... -
Well integrity for CO2 injection from ships: Simulation of the effect of flow and material parameters on thermal stresses
(Journal article; Peer reviewed, 2017)Ships have been shown to be the most cost-effective way to transport CO2 from many sources in the Nordic region to offshore storage sites. Injection from ships introduces new challenges for the integrity of CO2 injection ... -
Wet Drilled Cuttings Bed Rheology
(Peer reviewed; Journal article, 2021)The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ... -
Wetting of Carbon Cathodes by Molten Electrolyte and Aluminium
(Peer reviewed; Journal article, 2021)The extent to which the carbon cathode is wetted by molten electrolyte or molten aluminium metal is important for understanding the cathode wear during aluminium electrolysis. The present paper reports on a laboratory study ... -
What is the correct interfacial tension between methane and water at high-pressure/high-temperature conditions?
(Peer reviewed; Journal article, 2023)The purpose of this communication is to draw attention to a puzzling inconsistency in the published data for the interfacial tension between methane and water at high-pressure and high-temperature conditions. The published ... -
Wire and Arc Additive Manufacturing with TiC-Nanoparticle Reinforced AA5183 Alloy
(Peer reviewed; Journal article, 2020)Wire and arc additive manufacturing of aluminium-ceramic composites shows great potential to produce high strength materials. By incorporation of nanoparticles in the feedstock wire, fine-grained material with low ... -
Wire arc additive manufacturing of AA5183 with TiC nanoparticles
(Peer reviewed; Journal article, 2021)Aluminium alloys processed by wire arc additive manufacturing (WAAM) exhibit a relatively coarse microstructure with a columnar morphology. A powerful measure to refine the microstructure and to enhance mechanical properties ... -
Wire-arc additive manufacturing of structures with overhang: Experimental results depositing material onto fixed substrate
(Peer reviewed; Journal article, 2022)As additive manufacturing (AM) technology grows both more advanced and more available, the challenges and limitations are also made more evident. Most existing solutions for AM build structures layer by layer using strictly ... -
A workflow for synthetic data generation and predictive maintenance for vibration data
(Peer reviewed; Journal article, 2021)Digital twins, virtual representations of real-life physical objects or processes, are becoming widely used in many different industrial sectors. One of the main uses of digital twins is predictive maintenance, and these ... -
