Gas Sensing With Aerogels: A Critical Review on Structure‐Property Correlations and Performance Optimization

Advanced Science, EarlyView.
With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...

Liquid Gallium Nanozyme Coatings Enable Sustained Nitric Oxide Generation With Antioxidant and Anti‐Inflammatory Functions

Advanced Science, EarlyView.
Liquid gallium (Ga) acts as a catalytic center for nitric oxide (NO) generation within a tannic acid–zirconium metal–phenolic network coating. Stabilized Ga nanoparticles catalyze S‐nitrosothiol decomposition through surface electron transfer, enabling controlled NO production, enhancing endothelial biocompatibility, and providing antioxidant and anti ...

Cycloazulenylene

Angewandte Chemie International Edition, EarlyView.
A strained macrocycle consisting solely of azulene subunits, named [6]cycloparaazulenylene ([6]CPA), is presented. The macrocycle exhibits a notably narrow HOMO–LUMO gap for a pristine azulene species, strain‐induced red‐shifted absorption, and an unusual tubular packing motif elucidated via single‐crystal XRD.
