Chemiresistive sensors are currently the most popular gas sensors, and metal semiconductor oxides often used as sensitive materials (SMs). However, their high operating temperature means that more energy is required to maintain normal operation of SM, resulting in an increase power consumption entire sensing system. In order solve this problem, a microwave sensor embedded with multilayer Ti3C2Tx MXene split ring resonator (SRR) for nitrogen dioxide (NO2) detection was reported work. The takes advantage weak coupling between two SRRs achieve highly concentrated electric field Q-factor, which region serves avoid damage structure caused by excessive conductivity Ti3C2Tx. has good selectivity, lower limit 2 ppb, average sensitivity 98.66 mdB ppm–1 range 2–10,000 ppb at room temperature. Additionally, effect different lighting source performance investigated, reached best response (1.54 dB) under blue light. Finally, mechanism enhanced discussed detail based on results simulations tests. circuit designed work provides new approach MGSs first time introduces photocatalytic pathway into will contribute optimization future.

Abstract This study introduces a novel strategy for fabricating flexible nitrogen dioxide (NO 2 ) gas sensors based on Indium Oxide (In O 3 nanoparticles (NPs) employing selective reduction laser sintering (SRLS) technology. The SRSL technology utilizes ultraviolet (UV) to precisely and rapidly create oxygen vacancy (OV) defects in In NPs. These vacancies (OVs) enhance the active adsorption sites contribute additional free electrons, significantly improving sensor performance at room temperature. demonstrate excellent response ( S = 460.9 10 ppm), rapid response/recovery times τ resp / reco 27/570 s), superior selectivity (response ratio > 400), addition robust resistance light humidity (under ppm‐level NO gas). also exhibit low detection limit (200 ppb), high signal‐to‐noise (94.8 dB), good long‐term stability (25 days). Moreover, under photo‐assisted conditions, recovery speed of is further improved. not only provides an innovative development high‐performance but broadens application potential direct writing (LDW) advanced materials fabrications.

To achieve accurate and adjustable propulsion power, it is essential to utilize propellant materials undergoing repeated ignition combustion cycles. Injectable gel possess superior mechanical properties fluidity, allowing for the regulation of their process through precise control flow rate. Herein, an injectable conductive ion which uses hydroxylamine nitrate ([NH3OH]+[NO3]-, HAN) high-energy salt as matrix lithium perchlorate ( [Li]+[ClO4]-,AP) ammonium ([NH4]+[NO3]-, AN) adjust its conductivity was reported. The components this material exhibit high compatibility, confirmed by XPS FT-IR analysis, uniqueness conversion between liquid solid has established a good supply property. After centrifugation at 5000 r·min-1 15 min, eccentricity only 0.6%, demonstrating excellent stability. Compared with existing materials, delay time in single test reached 700ms under 225V 8ml·min-1. More importantly, can be reduced around 200ms after multiple tests, indicating ultra-fast response phenomenon that rarely occurs most research process, paving way realizing ultrafast application space propulsion.
