Oxygen‐Regulated GaN‐Based Sensors Fabricated by MOCVD for Switchable Gas Detection: Exhaled Gas Smart Platform for Non‐Invasive Disease Detection

Advanced Science, EarlyView.
This work presents highly consistent GaN‐based thin‐film gas sensors prepared by MOCVD for non‐invasive breath analysis. The sensors exhibit tunable selectivity from oxidizing to reducing gases by incorporating In composition, ultra‐low detection limits and humidity resistance.

Cathode Electrolyte Interphase Engineering by Quaternized Chitosan for Stabilized Li–SPAN Batteries

Advanced Science, EarlyView.
In this work, quaternized chitosan (QCS) is reported as an additive optimizing the sulfurized polyacrylonitrile (SPAN) cathode/electrolyte interphase (CEI). Its high positive charge density adsorbs PF6− anions, enriching the Helmholtz layer with aggregates. This promotes rapid anion desolvation, forming an anion‐derived CEI enriched in LiF.

Atomic‐Level Structural Characteristics of β‐Relaxation in Metallic Glasses

Advanced Science, EarlyView.
Using in situ synchrotron radiation X‐ray techniques, this study experimentally characterizes β‐relaxation at the atomic scale, linking it explicitly to tricapped trigonal prism (TTP)‐like atomic structures and fast atomic motions. Cyclic heating reveals β‐relaxation as irreversible yet reactivatable through rejuvenation, offering unprecedented insight
