Recent Advances in Ene Reactions with Carbon Enophiles

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

The Role of Operating Temperature on Pore‐Scale Gas Transport in Polymer Electrolyte Membrane Electrolyzers

open access: yesAdvanced Science, EarlyView.
This study clarifies the critical relationship between operating temperature and two‐phase flow behavior in polymer electrolyte membrane (PEM) electrolyzers by investigating pore‐scale gas bubble transport in the anode porous transport layer. Higher temperatures (80 °C vs 40 °C) result in a lower total bubble volume fraction and smaller bubble ...

Jigsaw Puzzle Inspired Patterning of Gas Diffusion Layers for Enhanced Water Management in Polymer Electrolyte Fuel Cells

open access: yesAdvanced Science, EarlyView.
A novel jigsaw‐inspired method introduces patterned hydrophilic domains into gas diffusion layers (GDLs) to enhance water management in polymer electrolyte fuel cells (PEFCs). This scalable technique improves high‐current performance by separating water and gas pathways, offering a promising advance for hydrogen‐based energy systems.

Unusual Van der Waals Magnetoresistance in Stacked Ferromagnetic Fe3GeTe2: The Role of Atomically Sharp Interfaces

open access: yesAdvanced Science, EarlyView.
Angular‐dependent magnetoresistance in stacked Fe3GeTe2 reveals high‐order UAMR that defies spin‐current‐based interpretations. Instead, it originates from internal electric fields at atomically sharp interfaces (ASI), in excellent agreement with two‐vector MR theory.
