Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

Concurrent Terahertz Spin Excitations and Phase Shift Control in Fe4Nb2O9: A Material for Synergizing Computation and Communication Technologies

Advanced Science, EarlyView.
A multifunctional terahertz (THz) platform is demonstrated, in a model material Fe4Nb2O9, exhibiting a large intrinsic THz phase shift alongside distinct THz magnon excitations in its antiferromagnetic phase. This coexistence of phase modulation and spin dynamics offers a promising pathway toward integrated THz communication and magnonic computation ...
