Three‐Dimensional Heterogeneous Bonding for High‐Density and Low‐Noise TMR Sensing Arrays

open access: yesAdvanced Science, EarlyView.
This study demonstrates a three‐dimensional heterogeneous bonding approach to fabricate compact TMR sensing units with double junction numbers and improved magnetic performance. Optimized Au─Au bonding and angled etching improve device integrity, noise characteristics, and magnetoresistance.

ROS‐Responsive Wedelolactone Hydrogel Promotes Intervertebral Disc Repair by Disrupting the NF‐κB–LCN2 Inflammatory Feedback Loop

open access: yesAdvanced Science, EarlyView.
A mechanically robust, ROS‐responsive hydrogel is engineered to treat intervertebral disc degeneration by targeting the NF‐κB–LCN2 inflammatory feedback loop. By delivering wedelolactone specifically within oxidative niches, this system disrupts macrophage–disc cell crosstalk.

Pt Single‐Atom Activates Surface Lattice Oxygen for Enhanced Acetone Detection Mediated by the MvK Mechanism

open access: yesAdvanced Science, EarlyView.
A Pt single‐atom‐loaded CuO sensing material is developed for acetone detection, demonstrating remarkably enhanced sensing performance. The introduction of Pt single atoms effectively activates the lattice oxygen of the CuO support. A new sensing mechanism based on the Mars‐van Krevelen catalytic mechanism is proposed, offering new insights into the ...

Efficient and Robust Heterostructure CeZrOx/NiO‐Ni Inverse Catalyst for Sustainable Photothermal CO2 Methanation

open access: yesAdvanced Science, EarlyView.
A heterostructured CeZrOx/NiO‐Ni inverse catalyst is designed for highly efficient photothermal CO2 methanation under low‐intensity light without auxiliary heating. It achieves 464 mmol·gcat−1·h−1 methane space‐time yield under natural concentrated sunlight, maintains stability over light‐dark cycles and extended air storage, and is scalable to 100 g ...

Controlled Optically Active Hierarchical Nanostructures of Side‐Chain Sequence‐Regulated Graphene Nanoribbons

open access: yesAdvanced Science, EarlyView.
The restrained side‐chain accessibility and versatility of GNRs extremely impede their multifunctionality, solution processability, and numerous solution‐based applications. We report herein a robust liquid‐phase bottom‐up synthesis approach for high‐efficiency preparation of side‐chain sequence‐regulated functional GNRs.

A Janus‐Like Bio‐Inspired Strategy for 3D‐Printed Bimetallic Metamaterials with Excellent Thermal‐Protection and Load Bearing Capacity

open access: yesAdvanced Science, EarlyView.
A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.

Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.
