Angewandte Chemie, EarlyView.Ammonia decomposition catalyzed by base metals: Exsolution of cobalt from perovskites prepared by spray‐flame synthesis (SFS) yields highly active, SrO‐promoted Co/La2O3 catalysts with low cobalt content. Operando studies provide insight into the function of the promoter. Dynamic surface reconstruction under operating conditions increases the interface

Spectroscopic studies of oxygen spillover on Pt/CeO2 catalyst
, 1997 Oxygen species adsorbed on the surface and in the bulk of a Pt/CeO2 catalyst have been investigated by FT-IR, ESR and FT-Raman spectroscopies. FT-IR and ESR spectra show that the dioxygen species, peroxide and superoxide, are easily formed on the CeO2 ...

Angewandte Chemie, EarlyView.A chemoenzymatic methodology is described that provided a panel of 6‐sulfo sialyl Lewisx‐containing glycans that were probed for receptor specificity of MERS‐CoV. Although the fucoside of 6‐sulfo‐SLex does not directly interact with the spike, it pre‐organizes the molecule into a conformation to allow a salt bridge between the sulfate and the ...
