With the emergence of novel sensing materials and increasing opportunities to address safety life quality priorities our society, gas is experiencing an outstanding growth. Among characteristics required assess performances, overall speed response recovery adding well-established stability, selectivity, sensitivity features. In this review, we focus on fast detection with chemiresistor sensors, focusing both time that characterize their dynamical response. We consider three classes operating in a architecture, exposed most investigated pollutants, such as NH3, NO2, H2S, H2, ethanol, acetone. materials, first selected nanostructured metal oxides, which are by far used chemiresistors can provide solid ground for performance improvement. Then, carbon layers (carbon nanotubes, graphene, reduced graphene), represent promising class operate at room temperature offer many possibilities increase sensitivities via functionalization, decoration, or blending other materials. Finally, transition dichalcogenides presented emerging chemiresistive bring what has been learned from graphene into quite large portfolio chemo-sensing platforms. For each class, studies since 2019 reporting display less than 10 s either listed. show layers, sum times already below s, making them devices measurements detect, e.g., sudden bursts dangerous emissions environment, track integrity packaging during food processing conveyor belts pace industrial production timescales.

Comprehensive Review of Hydrogen Leakage in Relation to Fuel Cell Vehicles and Hydrogen Refueling Stations: Status, Challenges, and Future Prospects

Energy & Fuels, Год журнала: 2024, Номер 38(6), С. 4803 - 4835

Опубликована: Март 11, 2024

As fuel cell vehicles (FCVs) are increasingly put on the market and hydrogen refueling stations (HRSs) built accordingly, fatal accidents caused by explosion due to leakage reported have become a critical issue. The results from complicated processes associated with so-called jet diffusion when leaks FCVs or HRSs, demonstrating its sophisticated characteristics presenting significant technical challenges. Recently, particularly in past few years, researchers established variety of theoretical models reveal relevant mechanisms introduced series monitoring/diagnostic approaches detect control hazards. This comprehensive review summarizes major research outcomes state-of-the-art progresses relation including (1) subsonic jets, (2) underexpanded (3) behavior, (4) hazard reduction methods for confined free spaces, (5) four types widely used detection technologies, (6) application diagnostic different systems. An insight is that related HRSs should be combined realistic characteristics. jets generated real gaps discussed, proposed based spaces. It suggested that, order integrate evaluate multiple sensor data points more accurately determine location level, artificial intelligence technologies could resolve issues encountered currently.
