Proteinvermittelte Kupfer‐Redoxregulation: Rolle von Disulfidbrücken und allosterischer Modulation

Angewandte Chemie, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Catalysis AI Agent Guides Discovering the Universal Design Principle of Cu‐Based Single‐Atom Alloy Catalysts for CO2 Electroreduction

Angewandte Chemie, EarlyView.
Artificial intelligence (AI) enables the systematic analysis and comparative evaluation of experimental and theoretical data, optimizes the catalytic reaction research workflow, and accelerates the discovery of high‐performance electrocatalysts. ABSTRACT Copper (Cu)‐based single‐atom alloys (SAAs) represent a promising strategy for optimizing the ...

Riesige Magnetostriktion im Ferrimagnet SmFe5As3

Angewandte Chemie, EarlyView.
SmFe5As3 ist ein neu entdecktes ferrimagnetisches Material, das ungewöhnliche volumetrische Effekte in Abhängigkeit von der Temperatur zeigt. Aufgrund zweier magnetischer Teilstrukturen – eines mit d$d$‐Elektronen des Fe und eines mit f$f$‐Elektronen des Sm – zeigen SmFe5As3‐Einkristalle negative (blau), positive (rosa) sowie konstante (beige ...

On the Structure and Redox Behavior of Ni and Cu Single Atoms Supported on Carbon Nitride

Angewandte Chemie, EarlyView.
Magnetic and electronic spectroscopies, combined with DFT, establish the MN4 binding site of Ni and Cu single atoms on carbon nitride and elucidate their redox photochemistry. Ni undergoes geometry‐preserving, reversible M2+/M+ cycling, whereas Cu collapses to an irreversible low‐coordinate Cu+ state, suppressing photocatalysis.
