Electrospun WO3/TiO2 Core–Shell Nanowires for Triethylamine Gas Sensing

Chemosensors, Journal Year: 2025, Volume and Issue: 13(2), P. 45 - 45

Published: Feb. 2, 2025

In this work, WO3/TiO2 core–shell (C-S) nanowires (NWs) were successfully synthesized by the coaxial electrospinning method and subsequent high-temperature calcination treatment. After some microscopic structural characterizations, although prepared WO3–TiO2 TiO2–WO3 C-S NWs displayed quite different surface morphologies, both of shell coatings uniform their typical thicknesses extremely close, with mean values 22 20 nm, respectively. gas sensing tests, exhibited good selectivity towards triethylamine (TEA) without significant interfering gases. Compared bare WO3 TiO2 NWs, showed better performance. Specifically, optimal operating temperature response to 100 ppm TEA 130 °C 106, which reduced 70 increased 5.73 times compared WO3, Obviously, nanostructures contributed improving performance materials TEA. Finally, hypothetical mechanisms proposed, expected have important reference significance for design target products applied sensing.

Homogenizing In‐Built Electric Field via Curved Conductive Nanonetworks for Electrochromic Fibers with Enhanced Switching Stability

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 21, 2024

Abstract Electrochromic (EC) fibers capable of optical transmission, reflection, and emission modulation are highly desired for promising applications in electronic display, adaptive camouflage, visual sensation. However, the non‐uniform electric field fiber structure lack electrochemically stable transparent conductive electrodes still limit practical EC fibers. In this work, scalable with long‐range performance electrochemical stability fabricated using Ag@Au nanowires (AANWs) nanonetwork parallel dual‐electrode. Benefiting from resistant Au shell layer that inhibits oxidation electrodes, maintain excellent even after 300 color changes. The synergistic interaction between unique AANWs dual‐electrode enables 10 m‐long to rapid switching speeds uniformity. Additionally, utilization mechanical looms weave long has facilitated application wearable displays,

Design Strategies of Integrated Metal-Oxide Semiconductor-Based Resistive Sensor Systems for Ammonia Detection

Electronics, Journal Year: 2024, Volume and Issue: 13(23), P. 4800 - 4800

Published: Dec. 5, 2024

Chemical production activities cause large amounts of ammonia to evaporate into the atmosphere, degrading air quality and even endangering public health, so monitoring in real time is significant. Traditional detection techniques, including spectrometers, chromatography, pumping methods, are characterized by high costs, complex operation, significant delays, limited compatibility, which obstructs immediate identification timely provision information. Due their distinct benefits such as compact size, affordability, quick response time, lack need for manual resistive sensors hold promise real-time tracking emissions chemical manufacturing processes.
