MXene‐Based Room‐Temperature NO2 Gas Sensors: A Meta‐Analysis

Advanced Science, EarlyView.
This study presents the first comprehensive meta‐analysis of MXene‐based NO2 sensors, decoding 32 study characteristics across 61 peer‐reviewed studies. By isolating materials chemistry as the primary performance driver over device‐level parameters, the authors establish a methodological blueprint and a predictive structure–function map to accelerate ...

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films

Advanced Science, EarlyView.
Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.
