Angewandte Chemie, EarlyView.Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Advanced Science, EarlyView.Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties
Advanced Science, EarlyView.Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Disentangling Elemental Roles in an Amorphous Medium‐Entropy Electrocatalyst for Oxygen Evolution
Advanced Science, EarlyView.An amorphous medium‐entropy FeCoNiMo‐a catalyst with a unique nanoring architecture is synthesized via a solvothermal method. The catalyst exhibits exceptional stability in anion exchange membrane water electrolysis, maintaining stable operation for over 600 h at 1 A cm−2.
