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.

Synthesis of Primary Amines via Reductive Amination of Aldehydes and Ketones Over a Ni‐Doped MFM‐300(Cr) Catalyst

open access: yesAdvanced Science, EarlyView.
Reductive amination of aldehydes and ketones to primary amines with high selectivity and yield can be achieved over Ni‐doped MFM‐300(Cr) in the presence of NH3 and H2. In situ inelastic neutron scattering, coupled with modeling, reveals that cooperativity between Ni active sites and MFM‐300(Cr) affords an optimal microenvironment for the selective ...
