3D modelling of β'' in Al-Mg-Si: towards an atomistic level ab initio based examination of a full precipitate enclosed in a host lattice
(Peer reviewed; Journal article, 2014)We extend a first principles based hierarchical multi-scale model scheme for describing a fully coherent precipitate in a host lattice to 3D simulations. As our test system, the needle-shaped main hardening Al–Mg–Si alloy ... -
Online monitoring of aluminium primary production gas composition by use of Fourier-transform infrared spectroscopy
(Journal article; Peer reviewed, 2014)Online monitoring of aluminium primary production raw gas is challenging due to the high concentration of HF in the presence of water. Tunable Diode Laser (TDL) analyzers retrofitted with sapphire optical windows allow for ... -
Grid independence behaviour of fluidized bed reactor simulations using the Two Fluid Model: Effect of particle size
(Peer reviewed; Journal article, 2014)It is well known that particle size has a significant influence on the grid independence behaviour of fluidized bed reactor simulations carried out using the Two Fluid Model (TFM) approach. The general rule of thumb states ... -
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 ... -
Evaluation of energetic benefit for solid-liquid phase change CO2 absorbents
(Peer reviewed; Journal article, 2014)A preliminary evaluation of desorption energy requirement for a precipitating system shows that precipitate formation results to a decrease in desorption energy requirement for a precipitating amino acid salt system compared ... -
Atomic-resolution electron energy loss studies of precipitates in an Al-Mg-Si-Cu-Ag alloy
(Peer reviewed; Journal article, 2014)Aberration-corrected scanning transmission electron microscopy combined with electron energy loss spectroscopy has been used to determine the distribution of Cu and Ag atomic columns of precipitates in an Al–Mg–Si–Cu–Ag ... -

CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods
(Peer reviewed; Journal article, 2014)One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ... -
Atomic-resolution elemental mapping of precipitates in a 7449 aluminium alloy
(Peer reviewed; Journal article, 2014)The high-strength weldable 7xxx series of aluminium alloys are of great importance to the aeronautics industry. Only recently, the complex structures of the AlZnMg hardening precipitates have been solved by HAADFSTEM imaging ... -
Prediction of solute diffusivity in Al assisted by first-principles molecular dynamics
(Peer reviewed; Journal article, 2014)Ab initio calculations of the solid-state diffusivity of solute atoms in bulk aluminium have previously been based on transition state theory (TST), employing transition state searches and systematic assessments of single ... -
A new and improved host-independent plasmid system for RK2-based conjugal transfer
(Journal article, 2014)Bacterial conjugation is a process that is mediated either by a direct cell-to-cell junction or by formation of a bridge between the cells. It is often used to transfer DNA constructs designed in Escherichia coli to recipient ... -
Synthesis and characterization of hybrid aminopropyl silane-based coatings on stainless steel substrates
(Journal article; Peer reviewed, 2014)Transparent and homogeneous hybrid aminopropyl silane-based coatings on steel were prepared by the sol–gel method using hydrolyzed γ-APS as a precursor. The coatings were fabricated by dip coating, and the effect of pH, ... -
Clustering and Vacancy Behavior in High- and Low-Solute Al-Mg-Si Alloys
