A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

Advanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Identifying Beneficial and Adverse Co4+ Species in Cobalt‐Based Oxygen Evolution Catalysts via Precursor Polymorphism Engineering

Advanced Science, EarlyView.
This study resolves conflicting roles of Co⁴⁺ species in cobalt‐based oxygen evolution reaction (OER) catalysts by engineering precursor polymorphism. Through controlled annealing of cobalt oxysulfide, researchers selectively stabilize γ‐CoO2 (enabling oxygen pathway mechanism) and β‐CoO2 (following conventional mechanism). γ‐CoO2 demonstrates superior

Direct Nucleation of Hierarchical Nanostructures on Plasmonic Fiber Optics Enables Enhanced SERS Performance

Advanced Science, EarlyView.
An unconventional synthesis strategy enables the direct growth of shape‐tunable nanostructures, from multi‐dot to multi‐arm designs, on silica optical fiber tips. This breakthrough boosts the sensing power of plasmonic fiber‐optic probes and unlocks new possibilities for large‐scale, in situ nanofabrication on silicate‐based substrates, including ...
