Unraveling Alkali Ion Electron Donation for Enhancing Heterogeneous Catalytic Oxidation

Advanced Science, EarlyView.
A new mechanistic pathway for potassium (K) ions as electron donors is identified by constructing single K ion chains confined within hexagonal WO3 tunnels. The as‐produced high‐electron‐density Kδ+ (0<δ<1) ions not only facilitate the formation of oxygen vacancies that behave classical electronic effect but, more importantly, also directly donate ...

Nanoscopic Mapping of the Extracellular Space in Amyloid Plaque‐rich Cortex

Advanced Science, EarlyView.
The extracellular space and diffusion around amyloid plaques are examined using shadow imaging and single‐particle tracking. Increased diffusivity is found near plaques, extracellular matrix alterations, and plaque core penetrability that varies with amyloid phenotype.

Deconvoluting Degradation Mechanisms in Anion Exchange Membrane Water Electrolysis Using Operando X‐ray Microtomography

Advanced Energy Materials, EarlyView.
X‐ray microtomography enables operando study of membrane degradation in running anion exchange membrane water electrolysers. By comparing membrane thickness and resistance changes in commercial membranes, the study reveals the superior stability of aryl ether‐free anion exchange membranes.

Prediction of One‐Dimensional Metallicity and π‐Band Superconductivity in Rhodizonate Radical Pancakes

Angewandte Chemie, EarlyView.
Equidistant stacking of radicals is typically unstable due to symmetry‐lowering distortions. We predict that such arrangements can be stabilized by multicentered covalent (“pancake”) bonding and Coulombic repulsion between negatively charged radicals.
