Reinforcing Particle Architectural Stability of Li‐Rich Cathode With Enhanced Anionic Redox Reaction Reversibility

open access: yesAngewandte Chemie, EarlyView.
In this work, we establish a direct correlation between internal compactness and particle architectural stability, identifying it as a key descriptor of cathode structural integrity. Simultaneously, the capacity contribution and compensation mechanism of ARR are resolved, revealing that the extent of irreversible capacity loss is governed by both the ...

Spatially Coupled Cl2 Confinement and Activation at Curved Ni Single‐Atom Sites for Highly Reversible Li–Cl2 Batteries

open access: yesAngewandte Chemie, EarlyView.
A robust cathode featuring curvature‐engineered Ni single‐atoms anchored within hierarchical pores effectively confines Cl2 and accelerates Cl0/Cl−1 redox kinetics. This synergistic architecture unlocks the potential of Li‐Cl2 secondary batteries with an unprecedented 1×106 mAh g−1 cumulative capacity, all‐climate resilience (–40°C to + 70°C), and 7.65

CO2‐to‐CO Electrochemical Conversion With an Fe(I) Porphyrin Complex in Water

open access: yesAngewandte Chemie, EarlyView.
Using in situ UV–vis/IR spectroelectrochemistry, we track CO2 reduction by a water‐soluble iron porphyrin. Rather than the usual [Fe0] intermediate in organic solvents, CO2 binds the electrogenerated [FeI] species and undergoes reductive C─O cleavage to stable [FeII‐CO]. This previously unexplored reaction pathway is facilitated by an aqueous H‐bonding

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

open access: yesAngewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.
