Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions
Advanced 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 ...

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
