Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

open access: yesAdvanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

N‐heterocyclic Carbenes as Adhesion Promoters on Aluminum Alloy 6061

open access: yesAdvanced Materials Interfaces, EarlyView.
N‐heterocyclic carbenes as novel non‐toxic surface primers for aluminum alloys for better adhesive bonding, because strong adhesive bonding shouldn't come at the cost of poisoning the human body. The impact of NHC functionalization on adhesive joint strength and durability is also evaluated using a single‐lap‐shear test, following continuous exposure ...
