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 ...

Signal Extraction from Inrush Current for Inter-Winding Fault Protection of Power Transformers
In case of transformer failure there is a high risk of losing part of power system, which can result in disruption for consumer power supply. This is the main reason for power transformer protection requirements to be so high.
