Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

Advanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Extremely Long Electron Lifetime in Spontaneously Passivated Polycrystalline Perovskite Layers via Illumination‐Assisted Trap Filling

Advanced Functional Materials, EarlyView.
ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...
