Summary: Sensitive and stable triethylamine (TEA) gas sensors based on a core-shell heterostructure comprising CuO and amorphous In2O3/ZnO (CuInZnO) were fabricated via a facile electrodeposition method. The optimized gas sensor (CuInZnO-3) showed outstanding gas response, selectivity, linear response, and stability towards 10 ppm TEA at room temperature due to the unique core-shell nanorod heterostructure with a high specific surface area and the amorphous nature of the In2O3/ZnO shell.

Summary: A room-temperature NO2 sensor with greatly enhanced sensitivity and rapid response/recovery speed under ultraviolet (UV) illumination has been proposed. The sensor based on In2O3/ZnO yolk-shell nanofibers exhibits remarkable sensitivity and quick response/recovery time, outperforming the performance in dark conditions. These results were attributed to the improved photo-generated charge separation efficiency and increased reactive sites and gas adsorption provided by the heterojunction effect of In2O3/ZnO yolk-shell nanofibers.

Summary: In this paper, TiO2/Ni/C composites were prepared using MOF-derived Ni/C materials for SO2F2 detection at room temperature. The TiO2/Ni/C composites-based SO2F2 sensor shows a wide detection range and fast response/recovery time, with a higher response value compared to the pure TiO2-based sensor. A dual-layer hybrid TENG based on TiO2/PVDF composite film was constructed, which enables a self-powered temperature and humidity-corrected SO2F2 sensing system. This work broadens the application of TENG in self-powered gas sensing and provides a new idea for trace detection of SO2F2 at room temperature.

Summary: The ZrC-SiC ceramic was successfully joined to 304 stainless steel using a Ti/Ni interlayer. The joining process involved a combination of transient liquid phase bonding and diffusion bonding. During the process, TiCx grew rapidly on the ZrC-SiC interface and precipitated as particles in the transient liquid, with its distribution and morphology controlled by the Ti gradient. Additionally, a small amount of Si dissolved into the liquid and precipitated as Ti3Ni2Si. The TiNi reaction layer transformed into a refractory TiNi3 layer with Kirkendall pores and Ni5Zr phase at the TiNi3/Ni boundary during solid-state diffusion. The maximum shear strength of 97 +/- 10 MPa was achieved.

Summary: This study investigates the oxidation characteristics of N-methyl pyrrole (NMP) through experiments and kinetic modeling. The experiments were conducted at various temperatures and equivalence ratios, and the species formed during NMP oxidation were measured using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS). A comprehensive kinetic model, based on previous models, was developed and successfully reproduced the experimental results. The study reveals the dominant role of hydrogen abstraction reactions on the methyl group and the formation of nitrogen-containing compounds such as pyridine and pyrrole during NMP oxidation.

Summary: In this study, the reactions between 2-furfuryl alcohol (2FFOH) and OH radical were investigated by quantum chemical calculations. The energy diagram and rate coefficients of the reactions were calculated at different temperatures and pressures. The results showed that H-abstraction from the side chain of 2FFOH occurred faster than from the ring below 2300 K. Additionally, there was a slightly positive pressure dependence of the total rate coefficients in the temperature range of 500-1000 K. The findings of this study could contribute to the understanding of the chemical reaction mechanism of furan-based fuels in the atmosphere and combustion.

Summary: In this study, RNA sequencing was performed on six key stages of Apostichopus japonicus development, and a total of 32,353 genes were identified. WGCNA analysis revealed that genes in the blue, yellow, and darkslateblue modules were highly correlated with the gastrula, auricularia, and blastula stages, respectively. Further analysis showed that these genes were mainly associated with signal transduction, cellular immunity, and extracellular matrix functions. The results of this study provide a comprehensive understanding of the molecular characteristics of sea cucumber embryonic development and theoretical guidance for larva rearing in sea cucumber culture.

Summary: The treatment of NOx has become an urgent issue due to its difficulty in degradation in air and its negative impact on public health. Among various technologies, selective catalytic reduction (SCR) using ammonia as the reducing agent is considered as the most effective and promising technique. However, the development of high-efficiency catalysts for SCR is severely limited due to the poisoning and deactivation effect by SO2 and H2O vapor. This review summarizes the recent advances in enhancing the catalytic activity and stability of manganese-based catalysts in low-temperature NH3-SCR, as well as discussing the challenges and potential solutions for designing a catalytic system with high resistance to SO2 and H2O.
