Meso‐Crowned Porphyrin as a Dual Cavity Hybrid Macrocycle for Improving the Efficiency and Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
This study demonstrates a dual‐functional porphyrin‐based passivation molecule, [12]‐C‐4POR, capable of simultaneously coordinating Pb2+ and Li+ ions through its porphyrin core and crown ether moiety, respectively. This molecule effectively reduces trap‐state density, suppresses non‐radiative recombination, and mitigates Li+ migration at the perovskite/

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

Advanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

A Janus‐Like Bio‐Inspired Strategy for 3D‐Printed Bimetallic Metamaterials with Excellent Thermal‐Protection and Load Bearing Capacity

Advanced Science, EarlyView.
A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.

Redox‐Mediated Electrochemical Regeneration of Spent LiFePO4 Battery Cathodes

Angewandte Chemie, EarlyView.
This work demonstrates a redox‐mediated electrochemical method for direct recycling of spent LiFePO4 battery cathodes. A water‐soluble mediator, iron propylenediamine tetraacetate (Fe‐PDTA), transports electrons into an off‐electrode reservoir where it drives compositional and structural repair of degraded LiFePO4.

How Halide Segregation Governs the Ion Density Evolution and Ionic Performance Losses: From Degradation to Recovery

Advanced Energy Materials, EarlyView.
Halide segregation (HS) in mixed‐halide wide‐bandgap (WBG) perovskites is key to the stability of perovskite‐based tandem cells and a central focus of large‐scale research efforts. Here, we find that the underlying reason for the poor stability of cells prone to HS is enhanced ionic losses during operation. Furthermore, we identified irreversible ionic

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.
