Design of Ti₃C₂T_<i>x</i>/SnO₂‑Selective Ethanolamine Sensor

Two-dimensional transition metal carbides/nitrides (MXenes) show great potential in volatile organic compound (VOC) sensors owing to their exceptional electrical properties, numerous active sites, and abundant terminal functional groups. However, pure MXene Ti3C2Tx is prone to oxidative degradation under ambient environment, and the insufficient response and poor stability are still grand challenges. Hereby, by deliberately introducing metal oxide semiconductor in multilayer Ti3C2Tx, a promising Ti3C2Tx/SnO2 sensor with excellent long-term stability and outstanding selectivity is developed for VOC monitoring. The research shows that the Ti3C2Tx/SnO2 hybrid sensor implements efficient detection of hydrogen-bonded gases and is especially highly efficient with ethanolamine (EA). The sensitivity of the hybrid sensor to EA is improved by over 10-fold in comparison with pristine Ti3C2Tx, besides the good selectivity to over 12 different VOCs. The synergistic effects of n-n nanoheterojunctions, the large specific surface area of 45.186 m2/g and mesoporous-rich hierarchical structure, and the functional terminal groups together facilitate the EA-sensitive properties. In addition, the innovative preparation of the Ti3C2Tx/SnO2 sensor, which takes advantage of terpinol, contributes to the close contact of Ti3C2Tx/SnO2 on the ceramic tubes, thus improving the sensor sensitivity. The scientific findings of this work may provide valuable ideas for the exploration of innovatively composite gas sensors

DataSheet_1_Genome-wide identification of the class III peroxidase gene family of sugarcane and its expression profiles under stresses.zip

IntroductionPlant-specific Class III peroxidases (PRXs) play a crucial role in lignification, cell elongation, seed germination, and biotic and abiotic stresses.MethodsThe class III peroxidase gene family in sugarcane were identified by bioinformatics methods and realtime fluorescence quantitative PCR.ResultsEighty-two PRX proteins were characterized with a conserved PRX domain as members of the class III PRX gene family in R570 STP. The ShPRX family genes were divided into six groups by the phylogenetic analysis of sugarcane, Saccharum spontaneum, sorghum, rice, and Arabidopsis thaliana. The analysis of promoter cis-acting elements revealed that most ShPRX family genes contained cis-acting regulatory elements involved in ABA, MeJA, light responsiveness, anaerobic induction, and drought inducibility. An evolutionary analysis indicated that ShPRXs was formed after Poaceae and Bromeliaceae diverged, and tandem duplication events played a critical role in the expansion of ShPRX genes of sugarcane. Purifying selection maintained the function of ShPRX proteins. SsPRX genes were differentially expressed in stems and leaves at different growth stages in S. spontaneum. However, ShPRX genes were differentially expressed in the SCMV-inoculated sugarcane plants. A qRT-PCR analysis showed that SCMV, Cd, and salt could specifically induce the expression of PRX genes of sugarcane.DiscussionThese results help elucidate the structure, evolution, and functions of the class III PRX gene family in sugarcane and provide ideas for the phytoremediation of Cd-contaminated soil and breeding new sugarcane varieties resistant to sugarcane mosaic disease, salt, and Cd stresses.</p
