Angewandte Chemie, EarlyView.A porous NHC‐polymer with large surface area anchors Rh amide sites to yield a stable and highly active catalyst for efficient hydrogenation of N2O and selective alcohol dehydrogenation, outperforming molecular analogues. Spatially arranged NHC sites prevent Rh deactivation and leaching, enabling sustainable conversion of a climate‐relevant gas into ...

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization
Annalen der Physik, EarlyView.A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

Active Transport of Macrocycles into Micelles Using Molecular Pumps
Angewandte Chemie, EarlyView.Artificial molecular pumps attached to polymeric micelles were found capable of transporting charged macrocycles into the micelles. The pumps operate with only modestly reduced pumping efficiency as compared to nonmicellar counterparts, indicating that ring‐threading molecular pumps can transport charged solutes into supramolecular assemblies, akin to ...

Quantifying the Biodegradation of Water‐Soluble Polymer Mixtures with Diffusion NMR Spectroscopy
Angewandte Chemie, EarlyView.The fate of polymers in liquid formulations in natural environments has not been extensively researched, in part as a result of incompatible analytical techniques. We show that diffusion NMR spectroscopy can be used to quantify the simultaneous biodegradation of multiple water‐soluble polymers with limited sample preparation, measuring the molar mass ...

Angewandte Chemie, EarlyView.In dieser Studie wurden die Veränderungen eines industriell relevanten CuO/ZnO/Al2O3 Katalysators während dessen Aktivierung und unter inversen Wassergas‐Shift‐Reaktionsbedinungen untersucht. Die Veränderungen der dielektrischen Eigenschaften durch H2 bzw. CO2, die als Elektronendonator bzw. ‐akzeptor fungieren, korrelieren direkt mit der katalytischen
