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 ... -

Zn Redistribution and Volatility in ZnZrOx Catalysts for CO2 Hydrogenation
(Peer reviewed; Journal article, 2023)ZnO–ZrO2 mixed oxide (ZnZrOx) catalysts are widely studied as selective catalysts for CO2 hydrogenation into methanol at high-temperature conditions (300–350 °C) that are preferred for the subsequent in situ zeolite-catalyzed ... -
µSR study of Al-0.67%Mg-0.77%Si alloys
(Peer reviewed; Journal article, 2014)Zero-field muon spin relaxation measurements were carried out with Al-0.67%Mg- 0.77%Si alloys in the temperature range from 20 K to 300 K. Observed relaxation spectra were compared with the relaxation functions calculated ... -
