Table 1 summarizes the application of MOS and metal-organic frameworks (MOFs) materials to gas sensors. Although the method based on GC is accurate, it is costly, not easy to miniaturize, and involves a complicated sampling process. The nondispersive infrared gas sensor also has the shortcomings of high-test cost, long test cycle, and not easy to miniaturize. Therefore, it is necessary to study a new type of gas sensor, which can not only be miniaturized but also run at room temperature to reduce power consumption.Capacitive gas sensor as an electrical sensor achieves the sensing effect by changing the dielectric constant [4][5][6] or dielectric layer thickness [7] after absorbing the target molecule. The capacitance value of a capacitive sensor is generally independent of the electrode material, and some materials with a lower temperature coefficient can be selected as the electrode, so its temperature stability is superb. At the same time, capacitive sensors have the advantages of simple structure, easy manufacturing, high measurement accuracy, and miniaturization. [8][9][10][11] Therefore, capacitive sensors have fantastic advantages when applied to gas sensing. The materials used in capacitive gas sensors mainly include zeolites, [12,13] metal oxides, [14] and carbon nanotubes, [15] but some shortcomings including high working temperature, high cost, and difficult process also limit their further development. [16,17] Therefore, a material with higher selectivity is needed for capacitive gas sensors.MOFs are an emerging class of microporous/mesoporous crystal material that assembled by metal ions/clusters and organic ligands through coordination bonds. MOFs materials have ultrahigh porosity, large surface-to-volume ratio and flexible skeleton, widely explored in gas storage, [18,19] separation, [20] catalysis, [21,22] magnetism, [23] and sensor. [24,25] According to the different structures of MOF materials, it can be divided into the following categories: MIL series, ZIF series, UiO series, HKUST series, IRMOF series, and PCN series, etc. Among them, the MIL series, ZIF series, and UiO series are widely used in the field of gas sensing.The MIL series mainly composed of transition metals (Cr, Fe, V) or lanthanide metals, and the ligands are mainly dicarboxylic acids (terephthalic acid, succinic acid). The MIL series generally have excellent stability and ultra-high specific surface area, which has a positive effect on gas adsorption and sensing. The ZIF series has a 3D network structure similar to zeolite, Gas sensors have been widely used in detection of industrial gas leak, air quality detection, and medical diagnosis. Although some chemical sensors have been commercialized, there are still some challenges such as sensitivity, cycle stability, and high power consumption. Metal-organic frameworks (MOFs) have high specific surface area, rich porosity, and excellent reversible/selective adsorption ability for various gases. Therefore, MOFs has been considered as an ideal sensing material. Metal active sites and...

Protective fabrics with air-permeable and flexible features are crucial for practical application in the detoxification of chemical warfare agents (CWAs). Zr-based metal−organic frameworks (Zr-MOFs) are desirable to exhibit outstanding degradation toward CWAs. However, generally, MOFs with powders cannot afford the utilization as a protective layer directly; meanwhile, it is still a puzzling challenge to integrate MOFs with textiles efficiently. Herein, we develop a scalable and controllable strategy to fabricate UiO-66-NH 2 on electrospun polyacrylonitrile nanofibers (UiO-66-NH 2 fabrics) firmly and uniformly to capture and catalyze 2chloroethyl ethyl sulfide (CEES) effectively for self-detoxification. The obtained UiO-66-NH 2 fabrics are greatly capable of specific surface area, ample porosity, excellent crystallinity, and abundant catalytic active sites. Consequently, CEES can be removed efficiently up to 97.7% after 48 h by reaction and adsorption. The degradation products mainly including ethyl-2-hydroxyethyl sulfide, ether, bis [2-(ethylthio)ethyl], and 2-(2-(ethylthio)ethylamino) terephthalic acid are detected. Moreover, the obtained nanofibrous fabrics possess air-permeable, washable, and flexible as well as lightweight merits, totally ensuring their promising engineering applications for protective clothing.

Some bacterial species of the genus Tenacibaculum, including Tenacibaculum ovolyticum, have been known as fish pathogens in the sea. So far, the only published genome sequence for this genus is for Tenacibaculum dicentrarchi, which could also be a fish pathogen. Strain da5A-8, showing 100% identity to the 16S rRNA gene sequence of T. ovolyticum DSM 18103T, was isolated from seawater at a depth of 344 m in Kochi, Japan, and grew optimally at 10 to 20°C. The genome sequence of strain da5A-8 revealed the possible virulence genes commonly observed in the genus Tenacibaculum.
