Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

Molecularly Engineered Dual‐Crosslinked Polymer Dielectrics for 200 °C Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work establishes a molecular engineering strategy that constructs a robust dual‐crosslinked network in polymer nanocomposites, achieving a record‐high energy density of 5.17 J cm−3 with >90% efficiency at 200 °C. The multiscale‐validated design simultaneously enhances dielectric polarization and introduces deep electron traps, resulting in ...

Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.

Cu‐Doped Amorphous High‐Entropy Hydroxides Activating Electrochemical Reconstruction: Triggering LOM and Chloride Repellency for Enhanced Water and Seawater Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Copper‐doped amorphous high‐entropy hydroxide (CuNiCoFeCrOH) is constructed via one‐step electrodeposition. Cu doping promotes electrochemical reconstruction by accelerating Cr leaching and re‐adsorption, triggering LOM and chloride repellency for efficient water and seawater oxidation.

Appraising Policies Through Social Multi‐Criteria Evaluation: Lessons From a Systematic Review of Applications

European Policy Analysis, EarlyView.
ABSTRACT In response to renewed interest in analytical tools that address complex policy problems and move beyond linear‐rational approaches in policy appraisal, Social Multi‐Criteria Evaluation (SMCE) integrates participatory approaches with multi‐criteria analysis (MCA), thereby incorporating specialised knowledge and diverse social values and ...
