Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Angewandte Chemie, EarlyView.Clade B carbon monoxide dehydrogenases (CODHs) remain enigmatic, diverging from canonical CODHs in structure and function. Here, we present the first characterization of Ruminococcus flavefaciens CODH (RfCODH), revealing occluded substrate pathways and attenuated CO oxidation activity.

Advanced Energy Materials, EarlyView.Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Angewandte Chemie, EarlyView.We propose an “amorphous oxygen mechanism (AOM)” for urea electrooxidation on amorphous NiWOx with tunable Ov, which achieves robust UOR activity and stability simultaneously. The “amorphous oxygen” in NiWOx prefers to escape during the UOR, in situ generating and stabilizing Ov, which thermodynamically promotes the reaction.

Safety and Feasibility of Magnetic Separation‐Based Blood Purification
Advanced NanoBiomed Research, EarlyView.We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Radical‐Mediated Dispersion Breaks Aggregation Limits in Carbon Thermoelectrics
Angewandte Chemie, EarlyView.We report a rationally designed small molecule (OTN) that effectively disperses SWCNTs via π–π and radical‐radical interactions, yielding hybrid films with a record power factor of 30.1 µW cm−1 K−2 and excellent flexibility. A nine‐leg device achieves a record normalized power density of 0.653 µW cm−2 K−2, setting a new benchmark for carbon‐based ...

Angewandte Chemie, EarlyView.Fe3O4 clusters can be precipitated onto Fe–N–C SACs through a residual‐oxygen‐assisted precipitation approach. Compelling evidence, including operando spectroscopy and ab initio calculations, suggests that Fe3O4‐cluster precipitates not only induce asymmetric electronic structures of Fe‐N4 active center to optimize the OH* adsorption, but also ...

Angewandte Chemie, EarlyView.We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...
