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

Advanced Science, Volume 12, Issue 43, November 20, 2025.
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.

Real‐Time In Vivo Monitoring of Cholinergic Neurotransmission in the Mouse Brain Using a Microelectrochemical Choline Biosensor

European Journal of Neuroscience, Volume 62, Issue 9, November 2025.
The measurement of choline as a biomarker for in vivo cholinergic neurotransmission is a valuable tool in the study of a range of CNS disorders. However, the continuous detection of cholinergic neurotransmission in selective brain regions in the mouse brain remains challenging and underexploited.

Prompting Interfacial Elastic Instability for Effective and Durable Icephobic Surfaces

Advanced Science, Volume 12, Issue 33, September 4, 2025.
To address the inherent trade‐off between icephobicity and the mechanical strength of icephobic materials, a new icephobic material design strategy is proposed by integrating fibrous construction frameworks and icephobic polymer. The structure prompts interfacial elastic instability and the subsequent undulatory interfacial stress at ice/solid ...
