Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells

Advanced Functional Materials, EarlyView.
This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Infinite families of trees with equal spectral radius

Examples and Counterexamples
In this note we show that for each positive integer a⩾2 there exist infinitely many trees whose spectral radius is equal to 2a. Such trees are obtained by replacing the central edge of the double star S(a,2a−2) with suitable bidegreed caterpillars.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.
