The effect of aerosol-deposited ash components on a cobalt-based Fischer–Tropsch catalyst
(Journal article; Peer reviewed, 2019)The effect of ash salts on Co-based Fisher–Tropsch catalysts was studied using an aerosol deposition technique. The major elements in the ash were found to be K, S and Cl. The ash was deposited on a calcined catalyst as ... -
Effect of amorphization-mediated plasticity on the hydrogen-void interaction in ideal lattices under hydrostatic tension
(Peer reviewed; Journal article, 2018)A thermodynamic model is derived to study the void nucleation in ideal lattices under hydrostatic tension loading and predicts that the plasticity has to be initiated before homogeneous nucleation of voids. Molecular ... -
Effect of Co incorporation and support selection on deoxygenation selectivity and stability of (Co)Mo catalysts in anisole HDO
(Peer reviewed; Journal article, 2019)A series of supported Co modified Mo catalysts was prepared by varying the Co/Mo ratio in the range from 0 to 1 while maintaining the Mo loading at ca. 10 wt%. A sequential incipient wetness impregnation method, with Mo ... -
Effect of composition and temperature on current efficiency for aluminium electrolysis from cryolite-based molten alumina electrolytes
(Peer reviewed; Journal article, 2017)The current efficiency (CE) for aluminium electrolysis in modern cells can be as high as 96 %. The main reason for loss in current efficiency is the so-called back reaction between dissolved metal and the anode product of ... -
Effect of Contamination on the Friction and Wear of Carboxylic Acids in Aqueous Lubricants
(Peer reviewed; Journal article, 2018)The friction and wear mechanisms of water-based fluids consisting of various types of carboxylic acids have been systematically investigated using a ball-on-disc tribometer on a super duplex stainless steel under boundary ... -
Effect of copper addition on the cluster formation behavior of Al-Mg-Si, Al-Zn-Mg, and Al-Mg-Ge in the natural aging
(Peer reviewed; Journal article, 2018)The time-dependent resistivity of Al-Mg-Si(-Cu), Al-Zn-Mg(-Cu), and Al-Mg-Ge(-Cu) alloys are studied over a range of constant temperatures between 255 K and 320 K. The resistivity vs time curves for the samples show three ... -
The effect of Cu and Ge additions on strength and precipitation in a lean 6xxx aluminium alloy
(Peer reviewed; Journal article, 2015)It has been demonstrated that the strength loss in a lean Al-Mg-Si alloy due to solute reduction could be compensated by back-adding a lower at % of Ge and Cu. Nanosized precipitate needles which are the main cause of ... -
