Photo‐Thermal Approaches on Polyimide Film for Demonstration of Sub‐50 µm Polymer Stencil Mask

Advanced Electronic Materials, EarlyView.
A photo‑thermal approach enables precise control of polyimide film properties during UV laser processing, achieving stencil mask fabrication with feature dimensions <50 µm—with the smallest features measuring 42.4 µm. This method maintains the polymer in its glassy state during processing, resulting in exceptional pattern stability and reproducibility.

Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Fe‐N‐C in Proton Exchange Membrane Fuel Cells: Impact of Ionomer Loading on Degradation and Stability

Advanced Energy Materials, EarlyView.
The impact of the ionomer to catalyst ratio for atomic Fe in N‐doped C (Fe‐N‐C) degradation in proton exchange membrane fuel cells is elucidated by advanced electrochemical techniques. Kinetic degradation dominants, with the reduction in turnover frequency of FeNx active sites initially suppressed with increasing ionomer loading.

Confining Surface Oxygen Redox in Double Perovskites for Enhanced Oxygen Evolution Reaction Activity and Stability

Advanced Energy Materials, EarlyView.
The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).
