Nonreciprocal Spin Waves in Nanoscale Hybrid Néel–Bloch–Néel Domain Walls Detected by Scanning X‐Ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers

open access: yesAdvanced Materials, EarlyView.
Using scanning transmission X‐ray microscopy, nonreciprocal spin‐wave behavior is revealed in real space in Fe/Gd multilayers with perpendicular magnetic anisotropy, highlighting their functionality for magnonic logic circuits operating at GHz frequencies.

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Ce Single Atom‐Engineered Amorphous/Crystalline Nanosheets for Enhanced Alkaline Water Electrolysis

open access: yesAdvanced Materials, EarlyView.
We leveraged Ce single‐atom engineering to generate short‐range ordered crystalline nanodomains in amorphous RuOx for creating amorphous/crystalline nanojunctions, in an effort to regulate the water dissociation kinetics for enhanced HER. Specifically, the Ce‐doped crystalline nanodomains greatly reduce the energy barrier to water dissociation and ...

De‐Saturation of Single‐Atom Copper Catalysts for Accelerating Propargylic Substitution Reactions

open access: yesAdvanced Materials, EarlyView.
De‐saturation of copper‐based single‐atom catalysts (De‐sat SACs) are realized by a KOH‐mediated Joule thermal shock strategy. Benefiting from the under‐saturation coordination environment of single‐atom Cu center, De‐sat Cu SACs exhibit remarkable catalytic activity in propargylic substitution reactions, tolerating a broad range of nucleophiles (N–, C–

How the Arrangement of Platinum Atoms on Ruthenium Nanoparticles Improves Hydrogen Evolution Activity

open access: yesAdvanced Materials, EarlyView.
A synthetic strategy for the formation of Pt islands and their transformation into Pt atomic strings on Ru nanoparticle surfaces is presented. The thermodynamically favored configuration of Pt strings on Ru catalyst is demonstrated to catalyze HER via the faster Volmer–Tafel pathway with a significantly improved intrinsic activity, owing to the well ...
