Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

open access: yesSmall, EarlyView.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Jump Diffusion Modelling for the Brazilian Short-Term Interest Rate

open access: yesBBR: Brazilian Business Review, 2015
In order to capture the informational effect of the Brazilian short-term interest rate (SELIC rate) by Poisson jumps, we build on the tests condu cted by Das (2002) and Johannes (2004), which show the significance of such structures for U.S ...

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.
