Quantitatively Predicting Angle‐Resolved Polarized Raman Intensity of Anisotropic Layered Materials

open access: yesAdvanced Materials, EarlyView.
This study develops comprehensive methodologies to predict angle‐resolved polarized Raman (ARPR) intensity profiles of anisotropic layered materials (ALMs), spanning from atomically‐thin layers to bulk limit. By considering birefringence, linear dichroism and multilayer interference, the complex refractive indexes and intrinsic Raman tensors are ...

Modulating Single‐Atom Pt Coordination for Enhanced Low‐Temperature Ammonia Fuel Cell Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
A bifunctional Pt single‐atom catalyst (Pt‐DG‐1) is discovered with enhanced ammonia oxidation reaction and oxygen reduction reaction mass activities compared to commercial Pt/C. It is shown that modulating the coordination environment of Pt single atoms is crucial towards dictating the electrocatalytic activity.

3D Acoustic Imaging Hitting the Diffraction Limit via Fully Parameter‐Optimized Meta‐Lens and Frequency‐Domain Reconstruction

open access: yesAdvanced Materials, EarlyView.
This article employs a binary genetic algorithm to design an ultra‐fine ultrasonic meta‐lens, achieving lateral super‐resolution imaging in the far field (>20λ₀). Building on this, longitudinal resolution is effectively restored through frequency domain reconstruction.

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 ...
