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 ... -
X-ray absorption, X-ray diffraction and electron microscopy study of spent cobalt based catalyst in semi-commercial scale Fischer-Tropsch synthesis
(Peer reviewed; Journal article, 2014)Calcined, reduced and spent Co-Re/γ-Al2O3 catalysts for Fischer–Tropsch synthesis (FTS) were characterized and compared. Co-K-edge and Re-LIII-edge X-ray absorption near edge structure (XANES), X-ray powder diffraction ... -
XPS Examination of the Oxide-Metal interface of an Al-Mg Alloy Containing Beryllium
(The Minerals, Metals & Materials Series;2367-1181, Chapter, 2018)The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ... -
Zeolite surface methoxy groups as key intermediates in the stepwise conversion of methane to methanol
(Journal article; Peer reviewed, 2019)This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites ... -
Zero Stress Aging of Glass and Carbon Fibers in Water and Oil—Strength Reduction Explained by Dissolution Kinetics
(Peer reviewed; Journal article, 2019)Understanding the strength degradation of glass and carbon fibers due to exposure to liquids over time is important for structural applications. A model has been developed for glass fibers that links the strength reduction ... -
