Fischer–Tropsch synthesis: Cobalt particle size and support effects on intrinsic activity and product distribution
Øyvind Borg,Pascal D. C. Dietzel,Aud I. Spjelkavik,Erik Z. Tveten,John C. Walmsley,S. Diplas,Sigrid Eri,Anders Holmen,Erling Rytter +8 more
TL;DR: In this article, the influence of cobalt particle size in the range 3 to 18 nm on the Fischer-Tropsch synthesis intrinsic activity and product distribution was investigated over 26 alumina supported catalysts.
Journal ArticleDOI
Characterization of alumina-, silica-, and titania-supported cobalt Fischer–Tropsch catalysts
TL;DR: In this article, the influence of different supports on the shape, appearance, and size of cobalt particles, as well as on reducibility, was studied by different techniques, including X-ray diffraction, scanning transmission electron microscopy, H2 chemisorption, N2 adsorption measurements, temperature-programmed reduction, and O2 titration.
Journal ArticleDOI
Wavefront dislocations in the Aharonov-Bohm effect and its water wave analogue
TL;DR: In this article, the wave psi AB possesses a wavefront dislocation on the flux line, whose strength (i.e., the number of wave crests ending on the dislocation) equals the nearest integer to alpha.
Journal ArticleDOI
Effect of artificial aging on intergranular corrosion of extruded AlMgSi alloy with small Cu content
Gaute Svenningsen,Magnus Hurlen Larsen,John C. Walmsley,John C. Walmsley,Jan Halvor Nordlien,Kemal Nisancioglu +5 more
TL;DR: In this paper, the effect of artificial aging parameters on the corrosion performance of air cooled AlMgSi(Cu) model alloy extrusions was investigated, and the results showed that IGC susceptibility was reduced, and finally eliminated, by artificial aging.
Journal ArticleDOI
Composition of β″ precipitates in Al–Mg–Si alloys by atom probe tomography and first principles calculations
Håkon S. Hasting,A.G. Frøseth,S. J. Andersen,Rene Vissers,John C. Walmsley,Calin Daniel Marioara,Frédéric Danoix,Williams Lefebvre,Randi Holmestad +8 more
TL;DR: The composition of β″ precipitates in an Al-Mg-Si alloy has been investigated by atom probe tomography, ab initio density functional calculations, and quantitative electron diffraction.
