Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.

Perovskite CsPbI3 Nanocrystal and Nanowire Incorporated G‐C3N4 Nanosheets for CO2 Reduction and NO Removal

Advanced Science, EarlyView.
CsPbI3 nanostructures integrated with g‐C3N4 formed S‐scheme heterojunctions enabling efficient photocatalytic CO2 reduction and NO abatement. The g‐C3N4/CsPbI3 nanowires achieved a CO production rate of 4.6 µmol g−1 h−1, while nanocrystal composites delivered 69.5% NO removal with only 5.0% NO2 selectivity, driven by highly energetic charge carriers ...

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

Advanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed
